pancake stepper on a bmg

trashcat

So I've tried to run a pancake stepper on my BMG w/ a volcano hotend a couple times now and every time I do it starts skipping. Because I've been running against deadlines I've just swapped it back out for a full size stepper. Does anyone have experience getting a pancake to work with the BMG? Do I have to adjust that little voltage dealy on the main board (creality 4.2.7), or should it just work? Thanks in advance.

check the data sheet on the stepper motor, yes it will most likely need the Vref tuned
for the stepper that comes with the bondtech LGX for example:
CUSTOM STEPPER MOTOR FOR BONDTECH LGX™

PH-06AWJ connector
2 phases
DC 5.5 V
Max 1.0A/phase
- To use the LGX, run the stepper motor with currents between ~0.45 and ~0.65A:
  
  > Be vigilant regarding the stepper motor surface temperature.
  > Keep it cool enough to touch. Lower Vref otherwise.
