Okay! I was looking at that and wondering. My close up vision is a little suspect sometimes so I put the ultra power readers on and looked a little closer.
If you want to send me 3 of those resistors I will take a shot at replacing them.
Pm me an address and ill get them out to you.
Im sorry it didnt work immediately. Did the board show up that way?
So I cleaned out the broken parts and put jumpers in across the terminals. Now I have 2 that āsort of brakeā and one that doesnāt. I am wondering if my bed is too heavy for it to stop once it starts.
Donāt worry about the resistors, I am going to order another board. Having some other issues now. Will be way easier in the long run!

Verify each channel actually shorts without power by ohming where the blue marks are:
Maybe replace all the resistors with shorts and make sure the jumpers are shorted for max resistance.
Im perplexed how those would break and stand on end like that in the photo. The resistor value was chosen to mock a motor coil resistance. The prototype Iām using on my lr4 z axis has a straight short and i had to creatively sequence the power up so it doesnāt fault and alarm.
Will pull it and play with it. I changed the enable pin to the x motor so that as @Jonathjon says it gives it time to start up.
I ordered another one (@vicious1 did not have to discount it BTW, I was happy to pay and support) If I can get this one cobbled back together I will put it on the V4.
I will put the meter on them when I get a chance. Busy night tonight but it might happen.

I can send 6 resistors
New board came today. Checked it and it looked great so I installed it. Works exactly like it should!
Pulled the other board and checked the terminals like you showed above. Some show shorts some donāt. poking around a little more I feel like you had a bad solder day that day! Not a problem on my end. It might be a reason for me to invest in a reflow workstation so I can do SMD in the future.
Super happy with the lack of a crash when the motors get disabled!
