Title: zero setting changes after running program
Post by: R A on February 06, 2021, 05:54:18 AM

My cnc mill works under win xp. I am using mach3 the latest version. I want to run a program on my mill several times in succession. The problem is that I have to set the zero setting every time again.
When the program is done the spindle goes to the zero position, but then it changes the coordinates of X, Y and Z. What is the problem here.

are only the displayed values on Screen not Zero, or is the machine physicaly not at Zero?

The machine is physically at zero except for the Z axis. When I pause and stop the program the coordinates don't change.

Thanks for the reply.
I mean pause and stop on the way back to zero after ending the program

have you selected in Config -> General Config -> Persistent Offsets and Persistent DROs ?

Hey
Thank you already for the answer. Yes the Persistent Offsets and Persistent DROs are selected. Things have been getting worse lately. I could pause the program and then manually go to zero, this no longer works because the machine coordinates are now also changing. It makes me desperate

Is the ESS plugin for using an ethernet connection?
My controller for the milling machine only works with parallel port. I have a 6040Z-S80 cnc milling machine.

I have installed v3.043_2018 but here I get the same problem but a little less.
Sometimes the coordinates remain correct.
