I am using re-arm from panucatt board (running smoothieware) with Ramps 1.4, on a custom build printer, 400x400x400 mm. I am using CNC microstepper drivers for all 3 axis that can go up to 4.2 amps, and 25600 microsteps. Right now they are set at 3200 microsteps. Nema17 48mm 1.7A 0.9° motors.
The problem I am having is that the print is shifting, and I can’t figure out how to fix it.
Before I had the re-arm board, I was using an Arduino Mega 2560 with Ramps 1.4, and it was printing good, no shifting! I did not make any changes to the hardware. I replaced the Arduino with the re-arm running smoothieware, and then the shifting problem started.
If I print in vase mode, it is printing perfectly straight, but when I print the test cube, it’s shifting on X & Y. It seems to be shifting equally on both axes, and also on every layer equally, and I find that really weird… if it was hardware problem it should shift on one axis, or more on one axis than the other, and also vase mode prints perfectly!
Things I tried:
changed acceleration
changed junction_deviation
changed microseconds_per_step_pulse
increased the amps on the microstep drivers
decreased microsteps
increased microsteps
Nothing fixes the shifting problem 
Someone please help me!
Thanks in advance
I wanted to post an image of the print, but the site does not let me post any links
