Actually, the table was done for long time, but I didn't have time to play with it. So last week, I tried to run it, but it was so slow. I use older version of hobbycnc driver board with NEMA 17 step motor that come with the kit. I use M6 threaded Rod, and cnc program is Jedicut and GMFC. I notice that the step motor is 0.9 degree per step. So, is this cause of slow running?
