General Mach Discussion / anyone ever have the screen go all jumbled?

« Last post by fast89 on June 25, 2025, 12:29:33 PM »

Only happens on 1 machine.  Windows XP. I've replaced memory, motherboard, parallel cable, video driver video card and probably a few other things. Only thing i have not replaced is the monitor. But i can unplug the monitor and it makes no difference. I can't make this fault happen. Anybody seen this?

General Mach Discussion / Re: Auto motor tuning

I think the answer must be "no" because there isn't a "settings" tab.  However in Mill the auto calibration button just calls a button macro and you could probably copy that across to Turn with appropriate modifications and add a button, probably to the "Diagnostics" screen.  However, all the "turning" macro does is set steps per unit which is trivial to do by calculation provided you know the screw pitch, any gearing between motor and screw, steps per rev and microstepping factor for the motor.

VB and the development of wizards / Re: Distinguish between pause caused by stop button and actual stop in mach3 macro

« Last post by FlavioDPP on June 25, 2025, 04:24:47 AM »

Hello all,
Experienced almost the same situation on a old colleague program in one machine with mach3..
He had a start cycle, pause and stop icon button.
Pushing stop button, the cycle stop (spindler, coolant stops) but remains in the current Gcode line...if we push start button, the program resume but there is no Gcode to start spindler and coolant.. This one was easy to solve with V-script button and then code OEMbutton (1003) followed by OEMbutton (1002)

For pause button is defined by System Function Pause... it Pauses the program except while is running G73 code (cycle)..
How i can pause it using Feed Hold ? Usually the Feed Hold button on other standard working screens is System Function Pause.

Finished Screens / Re: Mach3 DarkScreen Screenset - Now Available

What is the program you guys use to create screens for Mach3?
The Screen4 is a huge problem to work with... I have some customized old screens created by a old colleague and it's not easy to adjust it.

Hi, I know that on the mill side of Mach 3there is auto motor tuning. I am trying to tune the motors on a lathe using mach3 turn. Can I still use the auto tune from the mill side to tune the lathe. Thanks

Could be that the IP address at your home computer has been banned on this forum due to missuse by another user (dynamic IP).
You have not been banned and the IP address (130.155.97.132) you are using for this posting is good.

Third party software and hardware support forums. / JMC MCDC706 drives

« Last post by first off on June 22, 2025, 07:30:25 PM »

Has anyone had any luck with these JMC MCDC706 Brush DC drives? They are all over Ebay, Amazon, Aliexpress and elsewhere. They are cheap. They have an Alarm output function. I bought 3 of them. But I can not get them to communicate to any tuning software via RJ11 to DB9-RS232. RS232 has 2 different pinouts and I tried both. I also tried USB to DB9 (serial) converter cable. I can Get DCS810 drives to Communicate fine.
Any ideas would be helpful.
Russ.

General Mach Discussion / Some help needed.

Hi, I am using one of the cheap Chinese breakout boards for my lathe cnc convention. In the video it shows that you need to download the driver and input into the root directory of Mach3. Ok I did that. On start up mach3 asks which plug in I am using, so I tick the one I want. However the stepper motors will not move using mach3 turn. They will turn if I start mach3 mill. What have I done wrong, and how can I correct this. Thanks
