Anyone have success upgrading/replacing there Mononprice Mini select 3d (M200) to ramps?

My mainboard went T.U. and i tried using the ramps method, but I'm having a hell of a time with it.
I followed the instructions to the "T" over at instructables.com and even using an old Xbox PSU.


Messing with this for a while and I think I'm deeper in the rabbit hole.

In prontoface-Selecting Red center (yx) it moves the y and x axis to center.
-Select Y home bed moves fully towards me and get an "Halt.Kill () Called!-Select x home moves all the way to the left. Move back to center, hit 100 steps and moves very little to the right. Disconnect/Connect and select 100 steps to the right, moves to the right.

Select center and tries to move to the right even more and I get chattering of the stepper. Disconnect/Connect Select x Home, hot ends moves to the left (not home), get errror. Kill() called! Disconnect/Connect Center and hit 100 to the left and it moves almost fully to the left. Hit 100 again finishes moving to the left and stops.
During this the Y doesn't move and stepper chatters because it's trying to +Y direction even though it's there already.

-Select Z home moves down, but not completely "home" and get halt error.-LCD when PSU is turned dims on me, w/o PSU and USB plugged it normal.-Tried both the original PSU and the 360 PSU.

Went through the steps several times and had a friend verify.

vref on the steppers are around .75v

Jumper to 1/16th

Purchased in 2018, but that's not to say I don't have an early V2...

I haven't done that, but can see if I can help.

What are you having problems with, or where abouts are you stuck?

That's the one. Not haven't any luck getting it to work properly. The LCD is all garbled and dims when I actually apply power to the board, power just from the USB of the board it bright.

I will get you better information over the weekend. I haven't messed with it for a few weeks because I spent a lot of time trying to get it work. I had to step away before I turned it into a toaster.

Sorry I have been busy and didn't have a chance to mess with it.

Decided I had enough and purchase another printer.
