hello all,
in search of a best and tough bi-polar stepper driver ,i ended up at
reprap's stepper controller.they built it for rapid-prototyping
machine.but as it accepts pulse and direction commands i guess it can
be used for CNC too.
http://www.reprap.org/bin/view/Main/...tor_Driver_1_1
the point that why i got impressed with this board is,bcz it accepts
inputs of max and min travel from the limit switches.this saves my lot
of input pins.
but befor building it i have some doubts in the schematic.(as iam little dumb at undestanding schematics now and as this forum visited by best CNC experts,iam posting here)
1.the power connector has input for both 5v and 12v.that 12v is ment
for stepper.say if my stepper is rated at 24v,then can i connect 24v
instead of 12v?
2.i don't understand the purpose of stepper adjust in the schematic at
all.what is the TP1 ment for?
if it to tune the current of stepper,how can i do it?
3.and what is for the Master and slave pins?
4.can i avoid connections SYNC,SYNC,ENABLE at input side?
are they required?
please help in understanding these issues.
Thanks and Regards
