I’ve slowly reached the Programming stage (it’s the first printer I have built) downloaded the .bin file onto the micro-sd card and turned the printer on. I had an error message: No Printer attached, I echo: ZZ.00. When I Ok’d this the display showed the status as BTT-SKR2 Ready (as opposed to Proforge 3 Ready in the guide)
The fans came on and the LED’s lit up. I added the display software on the SD card, which seemed OK.
The thermistor check seemed OK, apart from the hotend thermistor which was reading a minus figure. The end stop checks were OK apart from the filament sensor not showing. When a filament is inserted, the display still does not show the filament sensor on the endstop status.
The Probe and Print fans checks were OK
The Motion Checks did not work. The Z axis moved in the right direction, but moved 2x the distance ie instead of moving 10mm it moved 20mm. When the X axis is moved the carriage moved in both the X and Y directions, but half the distance in both directions ie X axis to move 10mm, it moves 5mm in the X direction and 5 in the Y direction. The same happens when the Y axis is moved.
I’ve double checked the wiring and the motors are in the correct sockets. I’ve wiped the micro-sd card and reinstalled it with the same result.
I hope someone can point this beginner in the right direction to get this printer working.
