No movmento on any axis, any conditons?
Hi
I'm using a ramps 1.4 board for my DIY printer(not yet existing, just testing motors and board on the table) and I can't get any motor movment out of the board, the DIRECTION signal goes high and low depending on the direction but there is no PULSE signal, checked with osciloscope. I have tested the stepper driver/motor with function generator signal and the motor is turning. No errors are present, limit switches are set to electric, normali open(digital inputs for x, y, z, max/min are low, 0V) thermistor is ok, showing ok. I have tried all posible pull up, pull down combinaions, eaven with a secund arduino bard, everithng is the same.
The printer is a delta.
are there any other conditions for starting.
tnx
