please see the attached video.
this is a home built machine using grbl. sketch was made on fusion 360. its arabic text extruded.

the machine seeks at good speed but when it comes to cutting it moves in VERY small steps. I just need to know the parameter responsible for this. is it in the drawing or in the GRBL settings?
any help would be much appreciated.

thank you.
