Same here. I have a Pyramid A`1. Owned A8, Tevo, Prusa, etc. Always used Slic3r. Tring to got with Cura. But a lot of crashes and stopped jobs.
4.9.1 is the version. Prints with Repiter/Slic3r, locks up 50% of the time with Cura. I just changed out cable, shorter one. I tried to move to another machine (Dell) and USB would not work. I did load the adafruit this time. Will not do that again, the USBs should work from Windows/Microsoft just fine.
Will all mentioned here and report if I find a fix for me.
