I hacked out the emc_pause code from the mini gui and it seemed to work OK. There might have been an oddity in the backtrace display when you turn it on while running a program, but that doesn't bother me (I'm leaving it off anyway). So I tried dialing down my extruder temperature 10 degrees and started a print. 3+ hours later, I got my best looking vase so far, but there were still a few issues with the print (before I was getting more like 20+). To continue testing, I switched back to the Axis gui and dialed down the temperature another 10 degrees (now at 160 deg. C vs. 180). PERFECT! This time I got no flaws, and I have my first-ever correctly printed spiral-mode 1 wall thickness vase! Pics or it didn't happen: https://plus.google.com/106079792142766516843/posts/etDYDuRBpgw Thanks for putting up with my running around like a crazy fool. The Mini gui commanding a pause really sent me off into the weeds for a while...I'll try not to let it happen again, but no promises. :) ...and I learned something about 3D printing along the way. I've run long prints w/o issue before on LinuxCNC, but they had a lot more infill (which extrudes lots of plastic quickly). Doing the whole print at a slower speed for the vase apparently let the plastic sit around enough it started to cook and cause problems, while printing more 'typical' objects masked the over-temperature issue. -- Charles Steinkuehler char...@steinkuehler.net
