I am using multiple Polar 3D Printers but all have similar problems, and have had these problems for years.
Printer # P3D00575 says "Ready to Print", but I can't click on START to begin the print.
The other printers, P3D00579, P3D00582, P3E00577, say they are unconnected, and won't connect. Some of these printers have never been able to connect.
These printers are used at an after-school kids program, and it would be great to have them working.
P3D00575 used to print, and eventually it developed some calibration problem, where models we print appear twisted, because the rotation plate is having some issue.
