On going chinese 6040 problems

[amxen]

OK last testing for this evening . I just wend down and changed it all back to how it was and then changed the step pulse to 15 and the dir pulse to 10 . Dont know why them numbers i just thought i would see what happens. I now have it set like this and it seem not to be stalling

steps per = 320
velocity = 1700
acceleration = 160
step pulse 15
dir pulse 10

i have no idea about the step and dir pulse but it seems not to be stalling like this . and i cant stall the motors by hand .
I did try it faster (1800) but it did start stalling so i wound it back down.

gonna try cutting some mdf tomorrow. This was the first thing i cut when i got it just to test it
