@lansky: Is this still a problem in 126.96.36.199?
@b-morgan: Does this happen on 188.8.131.52?
I have noticed this too. Usually, you have to click the "extrude more" option several times before it actually comes out.
It still happens from time to time. On a scale of 1-10 of severity, I would consider it a 3, as it is annoying, but not preventing the printer from working entirely. We can close this ticket, and open it back up later if it crops up again.
@alexei I believe this was fixed in the newer Firmware versions but I will double check.
and FWIW, we had the same USB issues with Cura Legacy and Pronterface when we were using Slic3r
@logan , Any updates on this?
@logan, OK, the USB hub problem is a known issue and USB hub should be avoided when connecting printer to computer, closing this one out as resolved.
@MikeR , is the issue solved?
