Mach4 General Discussion / upgraded firmware now M6 fails most of the time
« on: April 11, 2018, 10:24:50 AM »
I upgraded firmware on my PMDX 411 and am now having issues in regards to M6 command. When I debug it works fine, but when I run it as a command it gets stuck on "mc.mcCntlGcodeExecuteWait(inst,"G90 G53 G0 Z0.0")" The command executes, but instead of going to Z0.0, it gets close .047ish. If i manually do am MDI "G90 G53 G0 Z0.0" it goes to where it needs to no problem. I did a debug and attached it. I see it is waiting for a motor 2 to stop, which it doesn't get. then an odd thing happens a few seconds later where I get a "Signal id 1123, (machine coord), changed from Low to High"
Just guessing here, but it seems that the probe function was tying up the command some how. I put ">>>>" where it is hanging up. I do get an occasional stop when the probe touches the plate and it just stays there instead of continuing. may be related, but one thing at a time.
Any help would be appreciated.
