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

« Last post by fast89 on June 30, 2025, 07:16:13 PM »

I turn off the tool path display before running a long bar feed program. Have not had it happen in 2 days. Seems to be a toolpath/memory problem.

PoKeys / Re: Pokeys 57U - Spindle Speed Control

In terms of the circuit, they have shown one with a simple Op Amp. I agree, its not that difficult.

In the manual currently online, no Op-Amp circuit is shown.  I suspect this may coincide with the introduction of the CNC version, which has a 0-10v output built in.  I suspect we're talking about an RC on the input to an Op-Amp with a gain of 3 or so.  But I'm not sure of the frequency, so I'm not sure of the RC values.  Any hints?

Hey lrgreen, would you mind sharing the answer you found? I’m running into the exact same issue with my setup and would really appreciate any insight you could offer.

When this happens, all motion and spindle stops. It is as if the cpu/motherboard crashed. Only thing that can fix it is pulling the power.

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

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?

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.

General Mach Discussion / Auto motor tuning

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
