WCS Problem with Linuxcnc/qtdragon was created by Bram kersten
I have avidcnc from 2017 from wich i recently replace the breakoutboard with a mesa7i76EU to make it work with linuxcnc.
Everything seems to be working fine,
The only problem i have is that it doesn't seem to use the WCS coordonates after i zero my machine But keeps using only the absolute coordinates when im running my gcode
This causes the machine(zaxis) to move into the bed when starting the program.
can somebody help me please.
Thanks in advance.i added my gcodeand my hall/ini files for qtdragon.

Why did you replace the original breakout board?
LinuxCNC can work with a lot of different hardware.
The bottom of the window seems to be cut off (the monitor is slightly too small perhaps), is it possible that there is some important information that we (most importantly, you) can't see?

Because we had problems with mach4 and our hardware wasn't compatible with linuxcnc.
and oops i see i frogot to f11 in my picture but there isn't that much more info only the status bar. but maybe you can see someting extra, im very new to linuxcnc/qtdragon so to me everything looks normal.
i added a picture with the fullcreen gui

Does t3 have x or y offsets in the tool page?

Your Z configuration seems to have zero at the bottom, normally not recommended.
I would change Z machine home to top, something like
[AXIS_Z]
MIN_LIMIT = -350
MAX_LIMIT = 0.001
HOME = 0.0

correct, i'm gonna change that, it's the safer option. sadly this isn't a fix for the problem.

Agreed.
Home belongs on the top for the Z axis.
Remember that all you need is 1 home swich per axis, limit switches are more of an extra safety thing.
