@phaedrux I tried but it is rejected as spam

@wild-bill-diamond after the top screen shot I did an rrf3 for a corexy and this is the results

@phaedrux here is a screen shot of 98 and part of 122 hope this helps

@wild-bill-diamond This is the test results I get with brand new stepperline motors. never had this problem before. I have a new board ordered. I would like to send this one back, have you look at it, if its bad because of me just throw it away, if its a bad board I would like it replaced and I'll pay the shipping. I have this board on all my printers, NEVER had a problem like this before.

This is the image I get after testing motors. I've got this board on 6 other printers and never had any problem. So I have no idea where to go.

@phaedrux I had the board mounted on a 2020 with plastic spacers and the other end with some tall spacers and I thought it was level enough but I guess not. This happened with 2 boards from the get go. I put a hair line fracture in the board. I figured it out this morning when this 1 board wasn't light up like it should and I put a little pressure on the board with a finger and everything worked ok. So I'm blaming me for doing a poor job of mounting the board. I just want to say thank you for working with me on the problem. I love the duet I have 2 delta, I3 and 4 corexy. I'm retired and I do this for a hobby. I have 3 printers, scratch built from the ground. So again thank you for the help.

@wild-bill-diamond I'm pretty sure I might have caused the problem because of the way I had them mounted, so I'm calling this case closed. Just a $300 learning error

Thanks for all your help

@phaedrux I just tried something and it worked. What I did was I had a dx2 board I hooked up. I'm using X as the test motor. On the dx2 it worked perfect and with the same commands on the main board it went to ground like before. So I'm sure the board is bad

@phaedrux I tested my motor wires and all was good, but when I tried to test a motor, same results. What I would like to do is box up the boards and send them to the experts and let them look at the boards. If they are bad because of something I did just throw in trash, and if just bad I would like replacements. I will pay all postage, I just need an address. I found another board I had and it is working just fine on the printer. Over the last several years I have ordered around 10 boards a couple of dx boards and a smart effector. Everything has worked perfect until these last 2 boards.

Thank you for any help you can give me.
