Hello togehter, i have create a part in the Fusion 360, export the STL file and send the STL file via Luban to my Snapmaker. The part has round about 77 layers and the Snapmaker calculate 11 hours for the printing. The first 12 layers are very fast and normal then print the Snapmaker 15 millimeters and make paused some minutes and then print again 15 millimeters and paused … After 7 hours he print 26% Has anyone given me a tip? Regards Michael ---

The estimated time is wildly inaccurate. Have no idea what you’re trying to print or your settings, so really can’t answer the rest. Need to share stl, print settings and possibly gcode. -S ---

I have found the issue. I have print the part direct via USB an Luban without problems. I have a problem with the UBS-C Port, now i receive the error message “Machine is not responding” on the touchscreen.
