Hi All, I'm a 40+yr vet of developing hardware and software for automated equipment, CNC, Pick&Place, Etc. Lately I have been purchasing Duet PCAs with RepRap Firmware loaded for motion control applications.
The Only thing I can't find that I need on every application is an equivalent to "FEED HOLD". What I mean by feed hold is, during any movement pressing feed hold decelerates all motion in a coordinated fashion. leaving the spindle going. when a continue button (sometimes the same feed hold button) is the machine Accelerates in a coordinated fashion from where it left off.
I do realize all of this was originally designed for printing but these controllers are proliferating into many other applications.
As far as I have observed this function is a hardware feature of CNC equipment. I do not know of a G or M code for this function
How can I accomplish this? I can't be the only one needing to pause motion.
Perhaps using an I/O bit and an addition to the firmware.
