Hi PeterE

I can't see how misplugging the motor connector would blow up the driver. One winding would not be connected and the other would be connected to different driver halves but this should not blow it up - perhaps someone else could explain this. Also misconnected would not allow the motor to turn at all as only one winding connected - a bit puzzling.

However, on a software note, the version I supplied you with has a bug, wherein if you set the extruder temperature over 260C it will reset to 210C. You can set the temperatures with gcode but they do not set correctly using the panel. I found this out because of the E3D head assembly instructions tell you to tighten the nozzle at 285C. I just did mine at 259 and it all seems OK. Also checked accuracy of E£D provided head thermister and it was spot on.

Good luck with swiftly resolving your motor issues.

Best Regards

The lerning curve is parrabolic goes on to infinity .

PK:
Unplugging a motor whilst the drive is powered will reliably damage the output FETS in any driver IC without a protection circuit either integral to the die, or added to the board. Not sure if it was powered or not.

PeterE:
picclock,
Sounds good that the possible damage on either motor or driver is small. Probably something else. Investigations will reveal. Also good to know about the extruder nozzle. I am not far from that one now I think.

chipenter,
So true, the learning curve is really a curve, but a very interesting one.

PK,
Nope, one of my ground rules. Never do physical changes to a powered up electric or electronic circuit. That will always create more problems as well as being possibly hazardous. In this case the machine was powered down and mains feed disconnected. But thanks for the tip, it is always useful to highlight.

PeterE:
Just for those who wonder if I am going to continue.

I am :thumbup: but first of all I need a break to get some perspective and find new angles, secondly the outdoor season has started with a couple of projects needing to be done before vacation. A new decking by the house is the one on the go right now. The old boards are becoming too soft for comfort being close to 40 yeas old.

Then another couple of smaller stuff and finalizing with a new outhouse/storage shed closer to autumn.

But I will slip in a note or two if I get something done on the printer. New parts are in the mail.

BR

/Peter
