You may want to get rid of the cat six line it’s very inappropriate for this type of set up and go to individual parents in a larger gauge as well as mount that VFD where it has a permanent ground set up. The other question is, where are your snubbers? For isolating your frequencies? I did not see them in your setup?
Just putting this out there. I have a LABVOLT 5400 CNC Mill and I am trying to wire it into a Mach3 controller to control using my laptop. If anyone can help me out I am willing to pay a little bit so that I can get this project finished. I just need help with the wiring and setup of the controller.
@@ryanwilson1369 you can certainly use Mach3. No issue. Cnczone.com Mach has a website. Personally I think you'll find Centroid CNC Acorn more robust and a little easier to setup as it is a hardware motion controller and software from the same company who has specialized in CNC machine control for over 30 years
I can not. That control is old and obsolete. I suggest you try CNCZONE.COM I picked up the machine to retrofit. Its been completed and I have since sold it.
That's been a long time. I do remember they are regular stepper motors I purchased from automationtechnologiesinc.com. These days I don't go with regular open loop steppers. I'd go with Leadshine closed loop steppers and drives. I don't recall what the torque rating of the original motors were. But they were reduced 10:1 so take the standard torque spec and multiply by 8-10 if you go with the closed loop steppers directly driving the leadscrew. There is a nylon gear on the leadscrew pulleys that are prone to cracking and disintegrating. I am also using Centroid Acorn now. I like the fact that the motion controller and the software come from the same company specializing in CNC machine motion control for over 30 years.
@@martyscncgarage5275 hey mate. thanks for your time. i was planing to go with closed loop steppers too, definetly. mine has 35oz-inch escap steppers on it, with an 1/10 reduction, just like you said. so 350-400oz-inch power would likely to be ok. but since i had never run the machine, i have my doubts.
@@martyscncgarage5275 and what about the teflon leadscrew nuts? how did they perform? did you replace them with ball screws and nuts? there's like, nothing, about this bad boy on internet. so please excuse my curiosity..
@@fatihdurmaz9826 leadscrews are generally fine. The nuts are made of Turcite. They can be adjusted. I think I have some documentation. Email me at my RU-vid channel name @gmailDOTcom and I'll send what I have. If the machine looks to be in good condition and perhaps yours has the auto lube it should be fine to run as is. But check those nylon gears...
@@martyscncgarage5275 mine has not nylon, but aluminum gears on the leadscrew ends. yet since i'm planing to do direct coupling, no need to worry. but they might be useful on a 4th axis someday? :)
@@uptechcncpvclt-1302 Which control? You should post these questions on the Centroid USER forums: centroidcncforum.com/viewforum.php?f=20 That way everyone learns from the question and answers.
@@uptechcncpvclt-1302 FYI, I used a Flashcut control on this mill because an entry level Centroid control was not available at the time. your issue is you need more inputs and outputs than something like Centroid Acorn can provide. We are testing an IO Expansion module now.
Hi Marty, I have been watching your videos on the Acorn and I had question on Connecting a DC Servo motor 3AM 48V from Dynethic Systems . The Servo motors came with my Techno CNC Lathe, is it worth trying to make them with with the Acorn or that's not really possible? - any insight would be great help. Thank you , kasra djkasra@gmail.com
Hey marty i have a chance to buy a dyna 2400 but the electronics were stripped out....it has the servos xyz ... Whats a fair price and shouls i buy it?
HI Marty, nice work. I have an Ezpath SD with a problematic control;. I have been looking at the Acorn or All-in-one Centroid. Mine has no manual gear levers like that one. Mine has CSS built in. It also has hand wheels on a sliding Apron on the front of the machine. Have you done one of those? I'm in Chandler,AZ. and understand you are in Mesa? I may need help with this if you are interested.
Hey Marty, I just bought one of these at a good price as the controller wasn’t working. Thinking of putting an acorn on it. I’m wrapping up my g0704 cnc conversion using acorn now. Any advice is welcomed.
Hi Kirk, the have a rather large spindle motor. If you use Acorn you won't be able to use the handwheel encoders. Otherwise I don't see a problem provided you get some AC servos that take step and direction input.
There is no code. There is a hall effect sensor on the spindle pulley for spindle orient. That is an input to the control. Once the control sees it, it applies the brake to the spindle.
@@martyscncgarage5275 okay well I have a Fidal 88hs and it worked fine a month ago I started it back up and now I'm having problems trying to get the spindle to orientate and pick up a tool. When I push m19 it just keeps rotating clockwise and counterclockwise and not locking I spoke to a person the other day who I can't seem to reach and he had me put in a S1 a S2 and then a m19 command. It worked yesterday but today it's giving me problems have you ever come across this issue? Can you recommend anything?
Man, sorry I missed that one. I just bought a Hardinge/Omniturn machine and the controller looks like it went through WWII. I am going to try and do the upgrades you did to yours since I cannot buy yours! Do you have a website you sell on or any way too keep up with you other than RU-vid public comments section? Thanks Marty!
Marty, I don't know yet. I just got the machine into my garage yesterday afternoon. I'm hoping to get some time this weekend to fool with it. Fingers crossed! Like I said, it looks BAD. I want to take the control unit/box off the lathe and test it on the bench as that seems like it would be much easier. I am assuming they are 110v (the lathe is 220 3 phase) Can't wait to check it all out. I am amazed at the quality of the omniturn components. They were really build well.
Well, it fired up but no video, so it is kind of hard to tell where I'm at! Lol. Okay, time to search for a video card and a LCD like you did. Thanks Marty.
Yeah thats what i figured....i saw one for salle $1295. Seems way to high...im looking for a deal not full retail....$500'i offered him hecsaid no...thank you.....
depends on where you are at and what comes with it. $500-$1500 maybe more to the right buyer. It will benefit from a control upgrade as the existing control is non standard. I paid around $500 each for mine, I have several
Marty, do you know what taper size is on the spindle bore of that machine. I have an EZ-Path with an A2-5 spindle nose but have no information on the bore. My Royal collet system is missing the spindle adapter. Do you have a part number for the adapter in this video?
Marty nice job. I'm doing the same project on the same lathe with centroid. Can you explain the speed lever configuration? How are you only using one lever 1-2-3? What is happening with the other two?
It's working very well. I sold the machine and am starting on retrofitting a knee mill very soon. You can follow my progress on my other RU-vid channel martyscncgarage
how's centroid running on this machine compared to bridgeports software? I assume that is what you mean, I have no experience with centroid but found the Original software super easy and very programming friendly.
Would the X axis behaving like it is be a result of the spindle encoder? Spindle Encoder is the original Heidenhain unit and its cable that came with the EZ Path Control. Spindle has a 1024 count and the handwheel encoders are 600p/r count rotary encoders.
Correction, the X axis comes all the way back when hitting CYCLE START to restart the program. In this video, I got spindle axis quadrature error. After clearing that error and hitting cycle start, X axis did come all the way back.
I custom made the motor mounts and Oldham couplers. No mods to the screws. I have a couple more machines and mounts to do them. just not time right now.
Hi ! I am in the process of converting the same machine, but I was wondering how you were coupling the axis motors to the lead screws? Did you modify the screws? or create an adaptor? Thanks for sharing!
Joshua Clark It has been reliable. I recently moved and have not had a chance to set up shop again. It will be awhile. I am using 4.5. I have a large knee mill I will be updating with Flashcut as well as an Emcoturn 240. House remodel comes first though....
It was running fine up until about a month ago when I sold the operator console who needed it. This is allowing me to upgrade the control to Flashcut. Same as my Dyna DM4400 and eventually my Emcoturn
hello. I represent an educational institution called CONALEP. We are looking to upgrade our equipment for teaching CNC and I found your video and I like it. at collage we have an emco compact 5 lathe can you help us with schematics and pictures. I would be grateful for your support thank you
Very cool, that slitting saw kicked ass.... You know how we talked about the G99/G98 difference on the canned cycles? This is where you could have used G98 on the first and second call (as long as we rapid down to Z.1 before the canned cycle and then used R-.3 on the drills as then it would have eliminated the air cutting down to the surface you end milled. A shorter 1/4" end mill would probably been better too.... but it worked, good job!
hello would u be willing to share ur program u used to test your md4400 i am looking a trying to buy one an would like to do a small test first..thanks radicalrescue@yahoo.com
Yes, and the original spindle drive, If I had it to do all over though, I would have tried to fit a 3 phase motor to it. I had to keep the transformer that came with the machine. It is an isolation transformer. The conversion I did is not for the faint of heart and it took me the better part of a year to complete. It IS doable. It was an enjoyable challenge. I do like Flashcut and was glad to have been talked into it.
You won't be able to keep the Spindle Servo motor and amplifier unless you keep the big transformer. The Servo Amp needs to be fed from an ISOLATED AC source. It was a big job. Your next hurdle is coming up with a way to invert the +0/10V signal so you can command the servo amplifier in reverse. I had to build a logic board to do it. If you want to run the tool changer, then things get much more complicated.Spindle orienting was my biggest challenge as you have to turn that spindle at a fixed speed in order to catch the spindle orient sensor. You also have tilt sensors on the ATC. I recommend you keep them. If you have the early machine with DYNA Skip control, then you also have to contend with the electromechanical drawbar and the ATC arm in and out. Its doable. But not for the faint of heart.It took me a year's worth of weekends to get mine done, and frankly, I am glad I used Flashcut instead of Mach3 for the conversion. Good luck! Take pictures along the way and if you get it done, please let me know. You will be one of the few that have converted a DM4400 successfully IF you get the ATC running. B-)
Hi Marty I purchased a dyna myte 4400 and will retrofit it with mach3. I've seen your thread on cnc arena .. it is super :-) the mill works fine, but old control, I have made a Super X3 mill with Mach 3 and some grinders I would like to reuse the large the DC servo and driver, it is possible that you could help me with some info on the DC driver? regarding signal + / - 10-15V start / stop, and where it is on the driver? (pins) I want to use C32 breakout board from cnc4pc.com and I have good experience with it. Sincerely, Thomas (Denmark)
Hi, very nice ATC. I purchased a surplus DM4400 spindle and am scratch building a VMC. Do you know where the inlet port is for the airblast? I think my spindle is the same as yours, but I don't see where the supply for the air comes in? Thanks, Walt
