Lucian, thank you for your support. I really appreciate it. Thank you for providing the tip as well. Please be safe. Vince

Did you tick it or untick it?I was having the issue that the machine coordinates wouldnt zero until i unticked persistent DRO and then everything was working as it should.

Y, thank you for your support. You don't need to use physical home switches with digital fixtures, and you shouldn't be using both physical switches, and soft limits. Your correct, that soft limits are simply to allocate chassis end stop positions. I recommend reviewing the video, and resetting them without the physical switches. Thank you, and you, and your family please be safe. Vince

@@corvetteguy50 You are most welcome. As far as the SL problem goes I have a suspicion that it may be attributed to the USB adapter/controller that came along with the machine. It is utterly disrespectful to the absolute character of the soft limits and to the role of the slow zones. Oh well....I thank you again. Wishing you the best through the circumstances.

I'm glad to have helped. Thank you for your support Vince

Thank you Jon for the support. You have to email me for the manual. Vince

Thank you for your support. Vince

I think it's looking for a physical homing switch that is not installed on my cnc.

Thank you for your support. I always suggest first removing Mach3 after copying your settings down to reinstall when you're experiencing odd issues. I suggest using Revo-Unistaller ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K_9fvehvv-w.html to make sure the software is uninstalled as if it were never in your computer before. Then after that you want to make sure no physical switches are activated. Its then time to proceed with the tutorial. If your version of Mach3 came bundled overseas its most likely pirated which can also have all sorts of issues. Thank you, Vince

Thanks for the reply and your info about the subject. The Chinese breakout board did come with a mach 3 install disk which I didn't trust at all... so I actually paid for a legit copy of mach 3 and downloaded the real mach 3. Haven't seen a single bug to date with the software. It's all been user error to some extent or another so far haha After a little more digging I'm pretty sure the machine is searching for like a proxy switch at the top of Z and that's why it never stops ascending the z axis. It would then search for the x and y proxy switches in the negative direction, if it were to ever find the z proxy switch. I'll have to either install some proxy switches or find a way to disable the physical switches in the software. Probably end up installing the proxy switches. Just in case the machine ever did lose power and the g code runs or something then I could tell it the same safe, secure, determined zero again. Until then, I've been able to run fine out of G54. It's just that each time I go to use the machine I have to zero everything for every work piece individually. But I would like a solidly defined fixed home position so I could use other work offsets. I could have jigs for neck blanks, fingerboard blanks, body blanks etc... these jigs would mount against stops in the table and it would make staging the work much less of a hassle. I only would need to clamp the work piece in the jig, zero the z axis for the cutter, turn the spindle on, mash to go button and go about other business while the machine creates the part. Again thanks for the info 👍 it's been a great help. I will eventually learn to use this machine effectively.

Ian, Thank you for your support. Take your time, and review the video as many times as required preferably with notes, and I'm sure it will make sense after trying it a few times. Thank you again, and have a great weekend! Vince

@@corvetteguy50 Referring to your video.....if you have limit switches on your mill does this mean you can/should use them to home the machine? In other words, if you set the program....whatever the code is...…..to go to home at the end of the program, isn't this a long winded way with long table travels etc to park your spindle out of the way when unloading and setting a new work piece as opposed to first raising the Z axis and then moving to a convenient X and Y position just clear of the vice, fixture...whatever? ….which is what I do.....just 2 extra lines of code. I have been told (if you want to) that you can home the mill to any place and not necessarily at the extreme limits of the table to the right end and the table up to the column with Z all the way to the top......so that would mean you would need to actually assign the home values and not have them by the limit switch. I think that it would be standard practice (in CAM software) to have the home position as table to the right and forward to the column with Z axis up due to CAM software understanding this procedure and positioning in all cases. ….your G54 work position will be the start of your program anyway for that particular workpiece. BTW...…..why does the table have to be forward to the column for homing...…..this puts the spindle towards you and the work vice away from you, meaning you need to lean over the table to load or unload the vice...…..perhaps I'm confusing a park position (set in the program) as initial homing, whereas homing is once set in the beginning and never altered.

@@gangleweed Limit switches can be used as home switches in Mach as well. The purpose of the video is to allow end users to try using soft limits, and fixtures the way they were designed to be used. A soft limit is simply a software input representing an arbitrary measurement of the CNC chassis end stops. A fixture is a programmed location on the CNC chassis no different than a GPS way point to allow end users to machine repeatably with digital accuracy. Utilizing soft limits for safety exceeds physical switches in safety, time, and monetary investment. I've had numerous clients, and potential clients deal with switch failures resulting in chassis collisions resulting in minor to major damage on larger systems. The beauty of the process I cover in the video is you can choose to use soft limits, and fixtures, or just use what you feel you want to for your particular machining preference. There's no right, or wrong as far as a method, but their certainly is a safer, cheaper alternative as I discussed in the video, and above. Thank you, and have a great weekend! Vince

Hey Carlos, thank you for your support. Here's my video covering offsets in Mach3. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-u8oFqMQit9E.html Thank you, Vince

Martin, If you set up the Safe Z setup in Mach3 it should be functioning, and if it isn't I suggest uninstalling Mach3 after copying all your setup information down, and reinstalling it as the Safe Z settings should be functioning. Thank you, Vince

Benjamin, Thank you for your support. I really appreciate it. I'm glad it helped you. Please be safe. Vince

Freedom, Thank you for your support. I really appreciate it. I'm glad to have helped. Have a great weekend! Vince

Lee, thank you for your support, and your correct. Vince

Marcetigreshark, Thank you for your support. I really appreciate it. I'm glad to hear you got them working. :) Have a great weekend! Please be safe. Vince

soft limits are properly used in addition to physical limit switches, not instead of them.

Hey Martin, Thank you for your support. You're correct with a slave axis Mach looks at the other Y axis motor as the first Y axis motor, so you need not worry about the axis measurements. Thank you, Vince

Al, Thank you for your support. I recommend uninstalling Mach3 after saving all your settings, to reinstall them later upon reinstallation. Once you've reinstalled the software you should be able to set the soft limits in Imperial. You must also be using a non-pirated Mach3 release as many of them are modified. Thank you, Vince

The software is licensed. Under Config select native units, it says not to use to change between metric and English G code.This for setting the units for motor tuning. So am I looking in the wrong place? Thanks for your help.

Ok, but the issue your having is resolved typically by uninstalling the software, and reinstalling it after you copy your settings down. Thank you, Vince

Steve, Thank you for your support. Mach is very powerful, and these settings will streamline your system, and its safety. Vince

I just reset my static system and if my other system works the same I think I'll have it. Once I clicked on Ref All I clicked on Soft Limits with none of those Pesky Soft Limit Warnings. I just need to figure out how to set up my Safe_Z.

Thank you for your support. I really appreciate it. Vince

Randy, Thank you for your support. You're correct you will leave Mach3 in G54 position, and upon reentering Mach3 following the same process. with hitting the Ref All button. Keep in mind you can't use physical switches in conjunction with soft limits. You can only utilize one or the other. Thank you, and have a great weekend!

Poh Di, thank you for your support. I'm glad to have helped. Vince

Hey Frank, thank you for your support. Unfortunately without seeing the process your doing I can't define what you're doing that is causing your error as there are a couple of variables. I do offer remote consultations if you're interested in scheduling one we're I use Microsoft Teams to remotely access your system, and diagnose the issue as if I were there with you which offers my clients the best learning experience. Thank you, Vince

Todd, thank you for your support. I really appreciate the kind words, and am glad it helped you. Please forward a donation to this Paypal address (payments only) Len1007@yahoo.com I do provide consultations, and Q&A support at the email listed in the videos description. Have a great weekend! Vince

Wesley thank you for your support. Do you have physical switches on your system? If you have physical switches setup for your system hitting REF ALL will move the axis to find them. Thank you, Vince

I had this. When setting up some months ago I had enabled Ports and Pins X Y Z Home. Unticking solved issue. Plz note I do not have physical switches.

Thank you for your support. unfortunately without seeing your system/settings its impossible to diagnose. If you want to setup a consultation just let me know. Thank you, Vince

Matt, thank you for your support. You can only utilize one or the other, and not at the same time. Soft limits must be used by themselves. I recommend removing the switches, and starting the process over again. Thank you, Vince

Thank you for your reply! I did find out later that evening thats what I needed to do. I did have to uncheck the "persistent coordinates" to reset the REF ALL HOME for machine coordinates. That allowed me to set machine coordinates to zero. I had then made the mistake of closing the program which didn't save my machine coordinates. So I re-zeroed everything set my coordinates. Then went back in and re checked the persistent coordinates box. Now all is set and everything is working! From reading the comments it looked like a few others months/years ago had similar issues. I'm not sure of they ever resolved it but I found this method worked for me and my set up. Thank you again for this detailed video it was extremely helpful!

I'm glad you got it worked out, and their working. Thank you again, Vince

nellinhos, thank you for your support. I would have to see the build your working with to analyze the potential issues as there's no way I can tell you what's going on from your description. I offer consulting, and can forward you the pricing if you email me. A place to start would be with my troubleshooting protocol here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FSQGvfGt2Qs.html Thank you have a great weekend, and please be safe. Vince

Hey Terry, Thank you for your support. I always suggest reinstalling Mach when setting soft limits up to assure the registry is clear from the program from when it was used previously. Thank you, Vince

@@corvetteguy50 Okay, thanks!

@@terryjones8360 You bet...:) Thank you, Vince

Jordan, Thank you for your support. If you encounter strange Mach3 software issues I highly recommend uninstalling it, and reinstalling it again to assure no settings have been modified once you copy down all your system settings to reinstall them after you perform the reinstall. Thank you, and have a great weekend! Vince

@@corvetteguy50 Thanks for the reply Vince, I've done that and still ref all doesn't change the machine cords

@@zviper Please review the video from here, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zFk_U3yqrks.html and try this to see if you still can't get them to zero the DRO's. If you can't then I would start the video from the beginning write every step down as you progress through it to see if the issue still exists. Thank you, and have a great weekend! Vince

Steinar, thank you for your support. I really appreciate it. You should set the software to support your preferred measurement system of either imperial, or metric. Thank you, Vince

Hi I did, and I use millimeters, I have taken engine tuning and I have axis calibration and everything seems to be nice when I run a file that I create myself, but now I upload the roadrunner.tap file as follows with marc3 and driving it is the figure very, very small? Can it may be that this file is made in inches and is using mm. Can I use the function (scale) and if you use it? And again, great video S Alpen

@@steinaralpenmob thank you for the follow up. Its possible that like you said its converting Imperial to metric.. You could always reinstall a version of Mach on another system to see if the scaling issue is resolved if you have access to one to validate its a software issue in the installation your currently using. I always recommend when dealing with strange issues to reinstall Mach, after writing down all your settings, and seeing if the issue is resolved. Typically it will be. Thank you, Vince

Hello again Vince I wonder what this (scale + 10000) is for? can I scale up "roadrunner.tap" with this feature? or is it for something else it should / can be used for

If you send me your email address I can send you the Mach3 manual. The buttons I've never used, but I believe its per each axis. Thank you, Vince

Did you try reinstalling it, and seeing if that corrected the issue? Thank you, Vince

no i have not..my cnc is in garage and its too cold out now and too dark..i have been messing with mach3 on my non cnc pc and it seems to function fine ... would you know what axis not refed to normal condition would refer to?... thats the wrror i get when i try to ref home in mach coordinates @@corvetteguy50

mach 3 is super cpmplicated and very powerful ... i can see why people have issues with it..its not user friendly at all.. it takes a lot to learn it and im sure i will not learn it..i just want to be able to enable soft limits.... lol

@@shelby50411I believe the software re-installation should get her behaving as she should. I have no idea what would cause that error. Thank you, Vince

Mach3 isn't very complicated if you break up learning it into sections. It essentially has 6 screen sets that contain all the information. I suggest learning what you'll use on each for your particular system, and digesting the rest of the information will come as your required to learn it for your applications. Thank you, Vince

Hey Carey, If you're using a CNC router this is incorrect. You'll want to review your settings again including if need be to reverse the axis to correct it, Thank you, Vince

Hey Sal, thank you for your support. I'm sorry it scared you :) Thank you, Vince

Joe, thank you for your support. I really appreciate it, and I agree when you learn soft limits your productivity goes through the roof, with maximum safety. Thank you, Vince

@@corvetteguy50 Noted. Just got my cnc router and it's kicking my ass. I'm so confused about the homing/soft limits. The router does have 3 optical homing sensors, so it's easy to get to machine zeros . But, I need a full understanding of the offsets, setups and limits. Will watch this video a few times before I setup to surface and drill the waste board

Practice, practice, practice is key! The optical sensors are really not the best type of physical switch to use if you want to go that way as over time certain ones drift from wear/dirt/debris. Thank you, Vince

@@corvetteguy50 Noted. I'm mounting a camera with cross hair this week. That way I can check the offset zeroes often and easier. I'll check on trip type switches later . These OMRON optical sensors are freaking expensive .

@@joeygonzo Sounds like a plan. Thank you, Vince

The Korink, thank you for your support. You can't use physical switches, and soft limits at the same time. I recommend disabling all the physical switches, and then following the video. If you still have issues then uninstalling the software after copying your system settings, and users license is the best way to resolve 99% of Mach issues. Uninstall Mach3 using this software, so its completely removed as discussed in this video tutorial ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K_9fvehvv-w.html Thank you, and have a great weekend! Vince

I am glad to got reply from You. Another question, can we use software for homing?

Yes, by utilizing the offsets in Mach3 covered in the video. Their essentially GPS locations on your table to machine from. Thank you, and have a great weekend! Vince

Rafael, Thank you for your support. I'm glad it helped you. Vince

@@corvetteguy50 Not at all... Vince I may have to reach you soon for help, I am starting a possible business that will require SMD placement and soldering in a transfer table, but I have hardware job before, Thank you again. Rafael

You bet :) Vince

Mezei, thank you for your support. I recommend reinstalling Mach3 after copying your initial machine settings down to make sure nothing is corrupted, and then attempting the soft limit setup again. Thank you, Vince

Hey Bob, Thank you for your support. If you email me I can forward you the manual. The TO GO button shows the distance to go on a commanded move rather than from the position you are at. Thank you, and have a great weekend! Vince

SlashPatry, thank you for your support. If your having trouble with Mach the first thing to do is to reinstall it to make sure your using its default settings. I would copy down all your motor tuning information if the machine has already been calibrated in order to move the settings to the new reinstalled version. Starting fresh usually always corrects the issues. Thank you again Vince

@@corvetteguy50 should i just copy all my pin selections and so on for the reinstall of mach 3 ? about to reinstall it tommorow, its gone crazy

@@airgunningyup Yes, and all additional settings if you have any set. Thank you, Vince

Hey Vijay! Thank you for your support. Unfortunately, I don't offer that service. Thank you, Vince

Ok I think I've figured it out. One you've set your G55 setting physically on your machine you have to go back to "OffSets" press G54 and Zero your axises to Zero then go back to "Program Run" turn on "Machine Coords" to check your G55 Settings, turn off "Machine Coords" and hit "Regen Toolpath" and the display will move your workpiece in the right place. Puhh.. lost a few brain cells there. lol...

Hey Martin, thank you for your support. The way to move the job over to G55 is to hit the REGEN TOOLPATH button once you have selected the G55 offset. , and your problem should be corrected. Thank you, Vince

JJ, thank you for your support. No, you shouldn't be able to jog past the set soft limit if its done correctly. I suggest uninstalling the software after copying down all your system settings, and then resetting them to see if this corrects the issue. Have a great weekend! Vince

Thank you for your support. I appreciate it! Vince

Isaak thank you for your support. You'll require a USB motion controller like a UC-100 in order to control the system utilizing USB format. Thank you, and have a great weekend! Vince

Thanks Vince I'll give it a go

I don't mind general questions, but if you require in depth support then I'll have to be compensated for my time. Thank you, Vince

A soft limit warning for whatever axis its related to means you've exceeded you're soft limits. This has nothing to do with what offset you're in as soft limits are based on the table's dimensions, and ends stops positions which won't change regardless of what offset you're in

The Storyist is correct in what they explained. Thank you Vince​

Clyde, Thank you for your support. I would validate the program your using to generate the code with as it could be do to your CAM software. Thank you, Vince

Alan, Thank you for your support. When it comes to feeds, and speeds there's simply no way for a precise measurement without some trial, and error. That being said plastics are fine to be cut with 800kw-1.5kw spindles. The best way to get a starting point is to contact the manufacturer of the endmill as they usually will recommend a starting point. If you don't have the support from the vendor here's a great little tool to use for a starting point. littlemachineshop.com/mobile/speeds_feeds.php Each tool will have their "sweet spot" based on the material their made out of which you didn't disclose above. Thank you, Vince

Der, Thank you for your support. Soft limits once set never change as their stored in Mach's settings as reflected in the video. The only thing that may change pending you never set an offset for where you plan on machining is your home location, meaning the location where you plan to start machining from. Thank you, Vince

Bob, thank you for the support. If your using a trial version of Mach that may be an issue. I suggest trying the retail version to see if the issue is eliminated. I would also recommend going over the process again carefully just to make sure you didn't miss step as it takes a few tries typically to understand the process. Thank you, and have a great weekend!

@@corvetteguy50 Hi Vince.I got myself into a complete muddle again. I've moved the Y axis to the front of the bed and the X axis to the far left, and set them as 0,0. My problem is that when I load gcode, e.g. Roadrunner, the Y axis wants to move further forward but is stopped by the zero setting. It's like the O,O position should be at the diagonally opposite end of the table. Tried all sorts of changes, one at a time but to no avail. When I manage to enable the soft limit, I just get the message asking if I want to proceed. I've also had the problem with a simple file I created in Fusion 360 loading with the 0,0 in the middle of the object. Any ideas?

Hey Bob, review where your zeroing the axis as you can't move past where the limit is set which is the issue your having. I discuss this in the video where you get the warning message your exceeding the soft limits. Review where your setting the G-code to be cut from on the table. Thank you, Vince
