The Lulzbot Mini 1 I use lost the ability to level. It had continuity between the nozzle and the power supply, and the washers and power supply, but the board wouldn’t see them touching during the leveling ceremony.
I got a new Rambo 1.3a from the store. I followed the instructions and the numerous pictures I took when I unhooked the original.
The printer now has a few problems that I can’t figure out:
- The USB connection works with my OctoPrint Server, and old Dell PowerEdge T110 that runs a bunch of printers. It does not work with my desktop, it uses COM4 at 250000, which is the proper COM.
< [23:31:30] Attempting to connect to None
< [23:31:30] Trying to detect 3D printer on COM4.
< [23:31:30] Attempting to connect to printer with serial COM4 on baud rate 250000
< [23:31:45] Can’t connect to printer on COM4
< [23:31:45] Closing the USB printer connection.
< [23:31:45] PrinterConnection.close: cannot join current thread (expected)
When connected through OctoPrint, which worked very well before the board change, every axis is reversed when manually controlling the printer. I don’t expect help with OctoPrint, it’s just the only way that I could use to connect to the printer. Cura-Lulzbot doesn’t work well on that Ubuntu install so I can’t test it there.
The case fan doesn’t start and there’s no voltage out of FAN2 when the printer is on.
Has anyone else had similar problems and have steps to resolve them?
