I hope this is posted in the right category, sorry if it isn't.
I have a Bigbox with single extruder, it's fitted with Duet Ethernet and PT100 on the hot end and connected to the correct daughterboard on the Duet. I also have the 7" Panel Due but I haven't tried to connect that yet given the problems I'm facing.
I'm having a nightmare trying to configure the X and Y drives, probably having the same problem with Z too but I haven't tried that yet.
Firstly I use M546 S0 H0 to allow free movement of the drives, then I attempt to home drive X, it travels in the wrong direction and for about 30mm and then stops. I have monitored the driver temp and there is no change at all, it stays at room temp, I'm using a temp probe on my multimeter to do this. Because the drive was travelling in the wrong direction I altered M569 P0 S0 to make drive X travel the other way except it doesn't, it makes no difference.
Now here's a real oddball, attempts to home Y result in X moving approx 30mm and then reversing and running the same distance back again, yes, this is X not Y. I have configured the drives with M584 X0 Y1 Z2 E3 I have only one extruder.
Finally when the drives stop travelling or part way through the travel error messages are transmitted, 'Short to ground' on any random drive number not normally the drive that is running but sometimes it is. I also randomly get a message that the drive windings may be disconnected again on random motor numbers. There appears to be no recognisable pattern to these error messages.
I've done a lot of trials with different motors to try to nail this but can't get anything conclusive. I have a good motor and harness I've been using which give results that follow those given by the motors fitted to the printer.
I'm puzzled regarding the incorrect direction of travel, the motors I have installed on the Bigbox were purchased from T3DP3D along with the cables and about the same time as I purchased the Duet. I'm assuming the cable harnesses are wired correctly to make the motors rotate in the correct direction when using M569 P0 S1 etc
Help anyone before I have a nervous breakdown
