Wall mounted 1F y axis problems

Hello, So i mounted my 1F on the wall with the y axis running vertically. I had a problem with the y axis not holding and dropping during a cut, so i upped the idle current on the stepper motor to 1.5 amp and that fixed the problem but now when the machine is away from home position and i hit the home button it homes z and x axis fine and then when it startes the y axis and the motor gives and the y axis drops to the bottom then continues to home. I am going to put a spring balancer on the x rail to help with the weight. Is there any other changes to the parameters that need to be changed to run the 1F on the wall?

I’m not sure mounting in that direction is recommended. Everything I’ve seen has the Y rails horizontal.

I am aware that they prefer the y rails to be mounted horizintally but for my space and electrical it had to go the other way. I have seen a number of people mount it in the same way as I have.

I tried the same ref below YT video and cannot recommend it. 1F will not support this either.

Hey Tom,

why exactly not?

I ask because if I would want to mount it vertically, I would mount it in this orientation.
