I have some old stepper drives that i am trying to retrofit to PC control, and i need square waves as a step pulse. the "on" and "off" time should be approximately equal. Can EMC do this?
As an alternate, pulsewidths of 50-100 microseconds seem to work acceptably, using TurboCNC, but i'd really like to use EMC2. I can't figure out how to adjust the pulsewidth.
The EMC2 documentation loosely says it turns the step pulse on when it needs to, and turns it back off during the next base period.
Obviously i can't run high speeds with this setup, but i don't need to either. The max speed my these drives and motors can support is about 2000hz
So, can i output square waves, or just longer pulses?
