Every time I try to home the machine (typing in a G28), nothing happens and the connection between the Octopus board and my laptop via USB disconnects (using the desktop version of CNCjs 1.10.2). This was all working until recently.
I tried to reduce the current on my X drivers (typing in: M906 Xnnn X2nnn). Once I checked to make sure the numbers were entered correctly before moving any motors (typing in: M906), I saw that I should not have put in that 2nd ‘X2nnn’ variable. I then re-did it (typing in: M906 Xnnn) and both my X drives were changed to the correct current. This is about when I was having issues with trying to home the machine and it not moving.
M119 shows all endstops are ‘open’ (not triggered).
M122 shows that the motors were not engaged. I then do a M17 to engage them and still no luck with any homing movement. I can’t even do a G1 X1 (or Y or Z). I sometimes get the message:
"echo:Homing Failed
Error:Printer halted. kill() called!
Have I fried my BTT Octopus board?
Are there any other troubleshooting steps I can take to determine if the board is now no good?
I have that gut feeling. Didn’t see anything obvious in terms of burn marks on the top of the board.
Sorry if this isn’t the right place for this, I am using the Marlin_V1CNC_SkrPro_DualLR_2209_2.1.1_515 firmware. I thought there might be some folks on this forum who have more experience in how to troubleshoot a board to determine if it is still good or not.
