Problems with Linux command CNC after switching to new computer
Posted: Fri Feb 01, 2019 11:44 pm
I have been running Sheetcam and a Candcnc mp3600 THC on Linux for almost 2 years now. Everything was working great until I recently. I got a new laptop and this is where I run Sheetcam (separate from the Linux computer). After downloading the most recent version of Sheetcam to the new laptop and making some cuts I noticed a few weird things. Before I was able to use cut rules to turn on and off the THC for things like corners, curves, and holes where I wanted to slow down and / or turn the THC on and off no problem.
After the sheetcam update now every time I try to use cut rules I get a ton of problems with the torch height in the spots where sheetcam is telling Linux to turn the THC off. Mostly the torch dives towards or into the material when the rules are applied. Cut height is set to .06 in sheetcam but sometimes when the THC get turned off it will run at a height of like .02 or actually drive into the material.
It runs pretty good with no cut rules, the THC on, volts set proper and VAD on but still dives a lot on images with lots of turns. This really sucks on things like 1/4" plate where I would normally slow way down in corners to make them nice and crisp and things like detailed images.
I also noticed it pauses way worse at the end of a cut when I use the THC off before end of cut rule. It did not do that before the update.
The only thing I changed was sheetcam on my laptop. I did not change anything with the Linux computer running the actual CNC machine.
What is going on here??
Is it possible that the newer version of sheetcam is cauing problems with the linux system?
Is it possible to go backwards versions in sheetcam to see if this fixes the problem?
