Haai
I have the hobby cnc pro driver board and 200 oz 3A steppers when turning the bord on and telling the steppers to move with mach 3 the stepers bind for 1/2 a second and then I can turn the steppers with my hand but dont turn at all
I connected my foamcutter steppers (127 oz 1 A) to the same board and they work fine
Dave Rigotti (hobbycnc.com) thinks it might be some setting in mach 3 that I got wrong
Please help
Thanx

Have you set the acceleration and velocity under motor tuning.

yes it is set to
X axis Y Axis Z axis
steps per mm - 2130 2130 2130
velocity - 300 300 200
acceleration - 100 100 100
step pulse - 5 5 5
dir pulse - 5 5 5
if not correct please tel me wat it should be
other settings:
Driver bord is set to 1/16 steps
and as I said the smaller 127 oz 1A steppers work great

Will you please send me your settings for mach3 so that i can just get jhe motors running and I can then later set it for my router
Thanx

Hi Johann,
every set up is different and you have to set each motor to its optimum by playing around with the setting until you get it running nice.
My settings are :-
X axis Y Axis Z axis
steps per mm - 800 800 880
velocity - 1750 1750 2250
acceleration - 55 65 50
step pulse - 1 1 1
dir pulse - 1 1 1
Try them but there is no guarantee they will work for your set up.
Graham.
