hey everyone
I have this issue that I did my absolute best to fix but with no luck,

I have a DIY CNC with CNC shield and NEMA 23, the NEMA 23 stepper driver is tb6600

I control the CNC using inevitables easel.

here is my issue, whatever grbl settings I use, the cutting will always scale down
for example, my bed is 450x450mm
when I want to cut a 10mm x10mm square, it will only cut 2mmx2mm square
I changed the feed rate and step/mm settings my results changed from 10x10mm square to 14x14mm square, however, if I add too much value the stepper will lose its mind and start spinning in place, I tried making accurate steps/mm and correct feed rate, but still same issue

note: before I used ramps 1.4 and everything works perfectly, I tried the same settings still no luck
any possible help?
