Hey everyone, I just received a PocketNC today and so far everything is going well for the most part as I learn how the thing works.
I am wondering if there is any parameters in the control than can be changed to adjust how the machine handles B-Axis roll over.
I programmed a simple 5x milling toolpath and I was able to get the code to run well using B axis values between -9999 and +9999, however this posses some issues:
1) When the program is done and I command G53 A0 B0 to send the rotary axes home, the B axis unwinds all the way from its current position back to 0 which takes a lot of time.
2) Having to keep the B between -9999 and +9999 inherently has limitations in how you can program. This is only 27 times around the part which is not much even for small parts if you are doing a 5x finishing with a ball mill and small step over. With this limitation, the program would have to retract the tool, unwind, and then come back and start cutting again if long finishing operations must be performed.
Is it possible to change the control to read B values between 0 and 360 and to always find the shortest path to get to the next specified position?
I seems like LinuxCNC's Wrapped Rotary parameter might be needed for this, but I don't know if that can be changed for the Pocket NC.
Any input is appreciated.
