Hi
My printer (UM3) have problems with communication with the print head. I often got ER18 with the text "There is a communication error with the print head"
It often occurs when the print is finished and the print head i "homing" to the start position. It´s also occurs after a (by me) aborted print - also when the print head is homing.
When I have dismounted/mounted the print heads, I often can print again.
Maybe has the ER18-problem started after I in this week updated the firmware, but I´m not sure.
What to do? Any suggestions?
