This is the first time I use LinuxCnc and a homemade cnc machine.
I created a stepper board driver with an IMT901 stepper driver and it works fine.
I would like to control these drivers using linuxcnc but I encountered a problem.
For a simpel test I connected pin 2 of my parallel port to the step-input of one of my drivers. This is the default value that 'emc2 stepper mill configuration' suggest. I can create a dummy configuration file with 'EMC2 stepper mill configuration' but when I want to test the motor it receives very slow pulses...
these are the settings of the x axis configuration:
motor steps per revolution : 200
driver microstepping : 2
pulley teeth : 1:1 (dummy value - I dont have a cnc yet)
leadscrew pitch : 1 mm/rev
max velocity : 2 mm/s
max acceleration : 5 mm/s^2
If I press the 'test this axis' button and press "run" I can see the step-led on my driver receiving approximate 1 step every second, this results in a very slowly revolving motor..
Am I doing something wrong?
I think that linuxcnc generates all the pulses needed to revolve the motor, or is this assumption wrong?
