CNC Mach3 | Tool Setting Touch Plate | Auto Tool Zero (Z Axis) | Includes INCH/MM Script 

Thanks for the detailed explanation. I'm sure it'll help some folks out.

@@sunny5rising Hi Charlie. I love your set up it makes me happy. May I please have a copy of your script please. Bill

Hi David, My old parallel port computer died and my only choice was to buy a newer one with Win 10 installed (what a dreadful system). I had to buy a genuine UC100 USB to parallel converter, but I eventually got it working. I was almost stopped dead in my tracks because I grounded the probe and no LED illuminated in the Diagnostics page. I have no idea what the board is, probably a Chinese knock off but the motor outputs are X axis 2,3 Y axis 4,5 Z axis 6,7 and A axis 8,9. Thank you for restoring my 'will to live'. I shall give your suggestion a try.

Thank you. Glad you enjoyed the video. Have fun with the script.

Thank you. Glad you enjoyed the video.

Excellent! Glad you got it working. And thank you for the compliments.

I agree. ALWAYS be cautious. Glad the scripts are working for you.

Excellent! Glad it's working out for you.

Thank you. Glad you enjoyed the script.

Excellent! Glad it worked for you.

You're welcome.

I did.

Very welcome and thanks for the compliments.

WoW!

Thanks for the input.

Hai Tom, how did you receive the the files?the link does not seem too forward it to my email.

Excellent! Thank you.

Email me at sunny5rise@gmail.com and I'll send the files.

You're welcome.

@@sunny5rising I just got it working and it works well! Thanks!

Excellent!

Absolutely!

@@sunny5rising Sounds like the subject of a video, right up your street.

Definitely. I actually started the works on making a video about this a little while ago, then had a computer crash. Thank you for the reminder. :) By the way, I also have the Digitize LED on my Offsets screen as well. Makes life easier.

@@sunny5rising Great idea, I hadn't thought of that, I may have some time later to add that.

Excellent! Thank you for commenting. Enjoy the script.

Ok, that's funny.

Excellent! Thanks for the information.

Thanks for your input.

blackcatunderwater can you may help me? I have also cncest machine, for mine it says probe to gnd(ground) and in4 , i have the usb motion controller from build your cnc

@@TheDanie1988 do you have the red BITSENSOR board ? If not I can't help sorry... You either need to ground the probe or supply a voltage to it. Had to figure that out on mine by trial and error

blackcatunderwater i have this on www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

Gracias. Me alegro de que te gusta los videos.

You're welcome.

Excellent! And thanks for the feedback.

Thanks. Glad you enjoy the videos. Yeah, we're staying safe around here.

You're welcome.

Great!

Thanks for the the compliment.

Vous êtes les bienvenus. Merci pour les commentaires.

what port and pin configuration did you use? I'm having problems with my stb4100 seeing the probe.

@@kboothrealty Hello Kevin as soon I get to my shop I reply you also you're going to update you're instructions on mach 3 but I pass it on to you to just copy and paste.

You're welcome.

you use inch and not mm

@@Dark_Phoinix hi i use both mm and inch if this dose not work for you try this www.cncrouterparts.com/pro-cnc-accessories-c-47_56.html there is a script here too

revb0 Awesome!

Rick McCaskill Excellent, let me know how it works for you.

Thank you. I've had some folks say the USB version works with ethernet. If you try it, test carefully.

You're welcome.

You're welcome.

Email me at sunny5rise@gmail.com and I'll send an edited script for you to try.

Thanks. Glad you enjoyed it.

I used it today, a couple of syntax errors in the script, deleted those and got it running nicely, thanks again.

Not sure about that, but thank you, lol.

@@sunny5rising 😂

You're welcome.

Very welcome.

You're welcome.

You are welcome!

Possibly, I haven't tried that.

Try this macro - CurrentFeed = GetOemDRO(818) 'Get the current feedrate to return to later PlateThickness = GetUserDRO(1151) 'Z-plate thickness DRO ProbeHeight = GetUserDRO(32) If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty DoOEMButton (1010) 'zero the Z axis so the probe move will start from here Code "G4 P2" ' two second delay Code "G31 Z-1.0 F5" 'Z goes down a max of 1.0 at 5IPM While IsMoving() 'wait while it happens Wend ZProbePos = GetVar(2002) - "Make your ProbeHeight" 'get the axact point the probe was hit, making sure to account for the tool offset which is not accounted for in 2002 Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun While IsMoving () Wend Call SetDro (2, "Make Your PlateThickness") 'set the Z axis DRO to whatever is set as plate thickness Code "G4 P0.25" 'Pause for Dro to update. Code "G0 Z1.0" 'retract Z to 1.0 inch Code "(Z axis is now zeroed)" 'puts this message in the status bar Code "F" &CurrentFeed 'Returns to prior feed rate Else Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if applicable Exit Sub End If Example for mine I use in my G0704 with TTS in a ER-20 tool holder and a 1/4 chunk of drill rod. My tool table seem to be working good with it. ZProbePos = GetVar(2002) - 3.883 'get the axact point the probe was hit, making sure to account for the tool offset which is not accounted for in 2002 Call SetDro (2, 0.758) 'set the Z axis DRO to whatever is set as plate thickness

Very welcome.

Alexis Damianidis Absolutely!

You're welcome.

You're welcome.

Glad you enjoyed it.

Oh my, lol. Thanks.

You are welcome and thank you!

Glad you got the script working the way you need it to. I have no specific ideas as to why it was acting up on you. Truly, I am only familiar with my system specifically.

@@sunny5rising i have same problem...i find a script that works for me for z probe... FeedCurrent = GetOemDRO(818) 'Get the current settings, OEM DROs (818)=Feedrate DRO ZCurrent = GetOemDro(802) 'OEM DROs (802)=Z DRO GageH = GetOEMDRO(1001) 'OEMDRO(1001)=Gage Block Height ZNew = ZCurrent - 300 'probe down 20 mm Code "G90F200" 'slow feed rate to 100 MM/MIN Rem Code "G4 P1" 'Pause 1 second to give time to position probe plate Code "G31 Z" &ZNew While IsMoving() Sleep(10) Wend Call SetDro (2,GageH) 'DRO(2)=Z DRO FinalMove = GageH + 10 Code "G0 Z" &FinalMove Code "F" &FeedCurrent 'restore starting feed rate dr.lin 2009.10.16

Hi Agent West, I have the same problem. Had the probing script crash into the plate a few times... disastrous... the tip was supposed to move up (in positive direction), and it does 9/10 times... Anyways, highly recommend doing a soft touch pretty much all the time until you are sure the script works. I'm using Mach3 USB. The best I could figure was that some of the code (OEM LED and OEMDRO) correspond to different fields for me. Switching between the workpiece/machine coordinates, I realised that the script was zeroing my machine coordinates. As Agent West suggested, I also removed the bit of code from the script ("Move to contact point due to overrun" bit), and changed all the G90 to G91, now the code works.

Ah, makes sense if it was using absolute coordinates instead of machine coordinates.

I also have a video and scripts for XY. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MQ9XT30s-PU.html

Email me at sunny5rise@gmail.com and I'll send the files.

I will have to do a video on this topic. There are several ways to continue an interrupted job in Mach3. Which way to do this depends on several factors (home switches installed or not, CNC program written in absolute or incremental mode, for examples).

Dear respected@@sunny5rising​, Please sir, I am facing some problem about the load shading. Here in Bangladesh, electricity cut off frequently. After completing almost 50% sometime 70% of the total program, sometime electricity cut off, then I can not re-start the program from the line where electricity cut off. Therefore, I need a good solution about the uncompleted design. Please sir, could you help me? I need your help

Dear sir, still I am waiting for your response. Please sir, I need your help.

Try this... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7yAEXM-rq1E.html

Haven't tried that or even thought about a negative value while programming. Did you try it?

Charlie Sarsfield yeah I did and it didn’t like it so much the probe touched the plate stopped then went down a further 5mm then returned to the standoff distance

If possible, can you make a short video of your touch plate or where you're zeroing? Also possibly your material setup and such.

Tried it today had the same problem

Make sure the Maximum Travel in the script variables section is set larger than your expected travel to touch the touch plate.

Do you have a USB connected machine? If so, email me at sunny5rise@gmail.com and I'll send you a USB test version of the script that'll probably solve that issue.

Very welcome.
