[LinuxCNC/linuxcnc Issue#271] M code greater than 199:M15816

#4 – SebKuzminsky 于 2017-05-16

I can reproduce this on the current tip of master (v2.8.0-pre1-3126), but it does not happen on 2.7.8. I’m testing on a 32-bit x86 VM installed from our 2.6 or 2.7 Live/Install ISO.

On both 2.7 and master, the active mcodes as reported by Status, both immediately after aborting the big program and also after trying to load 3D_Chips.ngc are: “M3 M9 M48 M53 M0”.

I wonder if this is also introduced by the same commit that caused the “G10” problem. Do we stuff something in the active M codes that is related to file position, and I’m erroneously trying to restore it?

Yup.

I’ll try to get this fixed later in the evening.

Thank you so much!

@TurBoss you’re welcome, and thank you for the actionable bug report. And I’m sorry again for introducing these problems! They are related to a feature I added that improves preview of “ungrounded” g-code programs, ones that depend on the current machine position and modal codes, rather than establishing them all at the beginning of the part program.
