Hi, On each print, the hot head freezes after changing layer. It seems the more time passes and the more it freezes. Less than a second freeze at the bottom and several seconds at the top.
On each freeze, some plastic is still extruded by the nozzle, leaving a bubble of plastic at each start. This makes the nozzle kick that bubble every time and makes ugly plastic spots all over the Z axis.
Regularly, around 98%, it won't recover the freeze and stays at starting position, making a big bubble.
If I pause the print, it takes a looooong time to actually pause and park the head. Then I can remove the big bubble and resume again... That crashes the LCD, it reboots on the resume print but showing 0%. If I hit resume, it goes to the right place but won't resume at the same spot, its like it missed a line.
I think I am using the standard Cura setting with PLA+ : 0.3 nozzle with 0.2 layer.
No temperature trouble when freezing, on both the bead and the head : no more than 1°C difference with what needed and most often 0.
Anyone experience this trouble ? Some Cura settings that could do this or correct the trouble ?
This seems to be a bug in the screen firmware. After the screen crash and reboot, re-printing will give a perfect print, with no freeze.
It's a shame because the first crash takes more than 6 hours to happen.
