I’ve got a new Low Rider 2 (no endstops) build going, and I cannot get anything moving. I’ve got an SKR-PRO-V1.2 which I built according to instructions (I think… pictures attached) and it’s flashed with the V1CNC_SkrPro_2209 (v2.0.7.2/510). I’ve got Repetier Host running on my computer and it shows that it is connected.
Nothing is moving in Repetier, nor the touch screen. I’ve got a TMC Connection Error on the touch screen. I’ve tried reflashing the board just in case, and I triple-checked my wiring and printer setting in Repetier. Can you guys help me troubleshoot what I am missing? (I hope it’s not something embarrassing easy, … wait… yes I do… ha!)
When I replaced it, the board no longer turned on. I must have something wired backwards. I guess I will try to get my tester back and test the polarity of my incoming 12V power source.
Guys, I’m at a loss. I put everything together on my board and it looks just like the picture in the instructions (except the the picture has 6 driver chips and mine came with 5). I replaced the blown fuse (15amp) and now the board does not power on, but does kick on if I remove the fuse again. I checked the polarity with a tester and it is wired correctly. The voltage from the power supply was 12.6 volts. Any suggestions would be deeply appreciated.
Thanks again for your help. Attached is all the jumpers circled. I double checked, and there are no jumpers underneath the driver chips. There are only 5 driver chips (hope this is correct that’s all that came with the kit). I also double checked that the sensor less pins have been bent out of the way. I confirmed with a tester that the polarity coming from the power supply is correct, and it is at 12.9v.
It is currently wired with 12v coming in to the board. The minute I put the jumper wires from the power inputs to the motor power inputs, everything turns off. The tester shows no incoming power when that happens.
Well shoot. Looking at the schematic I think the 15A goes straight to the cap on the power pin on the driver sockets. I can’t think of anything that could cause issues with the drivers out, it must be the first bad SKR we have had.
That sucks sorry Carden.
PM or email me your order number and we can get you situated ASAP.
