I managed to get the Helical Flexible Shaft Couplings off the right lead screw, but not the motor. On the left side I managed to get the coupling off the motor, but not the lead screw. I'm going to try to bore out the stripped set screw to save the lead screw. I've got new couplings arriving Friday, motors arriving Thursday, and I'll need to pick up some molex parts locally. I should be able to start on this project again newt week.

They are VERY hard screws! You may break a bit or two drilling them. I have! :oops:

Thanks for letting me know. I tried two different heads to bore it out and then a drill bit, but gave up early thanks to your warning. I ended up removing as much of the body as I could and then just carefully took a cutting wheel to it until I got enough gone that it just came off.

Just sent this to support but I'll use it to update my progress so far:

My stepper motors came in and I'm still experiencing the issue. After quite a lot of further troubleshooting I've discovered that when both motors are plugged in they don't work but when either one is disconnected the other works fine. I unplug left, right is fine; plug left in and unplug right, left is fine; swapping the motors yields the same. I'm wondering if this might be a power issue or a failing component on the Rambo board?

Sounds like the drive current that the RAMBo should be supplying is wrong.

Support suggested that I replace the board. Fortunately as I looked for places to purchase it from I found a 3D printing shop in DFW so I can get it today for $60 less with no shipping

Project and repair update

Repairs complete! Now that it's working I've printed out my mount and it puts the BLTouch too low. I've updated the design to accommodate this, it's a bit odd looking but I want it to be one, solid piece rather than an addon. More to come tomorrow I hope!

It works!!! I got the firmware right with the first install, ran tests and they worked :D

I will work on updating the OP with full instructions when I can.

Instructions are almost done! Everything up to the Z offset is done, firmware has been uploaded and I believe the "Required Materials" is also done.

I use a PAD-11 to crimp connector pins but I have done lots of pins with it.
