Mach 3 tolerance problem
« on: November 24, 2020, 05:08:46 AM »
Hello,

I'm useing Mach3 and CSMIO IP-S controllers on lathe. I'm using it for serial production parts.

The problem is that it doesn't hold part dimensions. I have try to run with and without backlash compensation, but problem say the same.

However it is working great for around 20parts, than jumps for around 0,04mm and so on.

I really kindly ask anyone to help me with that, as I'm really desperate. I need machine to run but I don't know what to do.

Thank you

Gasper

CSLAB recomends to use  R3.043.022 with their Controllers.
PLS Try this Version (fresh copy).

ftp://ftp.machsupport.com/Mach3/

from CSLAB Homepage:

...., it’s enough to install older Mach3 release (03.043.022 to 03.043.044). I recommend 03.043.022 release. It’s the most reliable in our opinion. It’s here: ftp://www.machsupport.com/Mach3/Mach3Version3.043.022.exe
 Run the installer and re-instal it (it will replace the version you have).
