Hello, the latest firmware (DM500 install 20191012.rar) has some issues. The same GCode which was running fine before now doesn't run properly. The work origin Z-axis resets to zero during the begin of the work. Needed to revert to the previous firmware (DM500 install 20190804.rar) to make it work again.

Here the GCode I was testing with:

Hello,

Thanks for answering so quick. Please find attached the parameters file I exported from the controller.

Hello,

Once again thanks for your support. The problem I'm having is not with the G28 going back to MACH Z0 but the ABS (work) Z being "re-zero" at the beginning. I thought it was fixed but not, the problem persists after I upgraded with the latest firmware and the same G-Code works with the previous version.

Here the link for the video showing the controller. You'll see the "Z" axis ABS (work position) zeroing in the new firmware.


Firmware 20190804 with G28 - OK
https://youtu.be/wAoYSiLU-SMIt moves to MACH zero and back to ABS work.

Firmware 20190804 without G28 - OK

Firmware 20200107 with G28 - NOT OK
https://youtu.be/q63IbdBXbQk
It moves to MACH zero, Zero "Z" (second 10 in the video) and back to ABS work.

Firmware 20200107 without G28 - NOT OK

I used exactly G-Code from my previous post. For the "without G28" I remove all lines using this command.

Thanks.

Helo enjoy_cnc,

Thanks for your reply. Yes, I already tested before and removing the T commands solves the issue so Z does not reset anymore. I'll explore the new T functions and update my G Code generation to assist for tool change process.
