Designing Spindle Speed Controller - Need Digispeed Specs
I've already completed the hardware portion of the controller (and it's working) and now need info to make it compatible to DigiSpeed/TurboCNC interface. TCNC is using the step/dir mode, my question is what's the minimum pulse width for digispeed and what's the maximum allowable update rate. My controller is standalone, i.e., connect direct to power plug of your spindle unlike digispeed which connect to the potentiometer.
Anyone has source code for TCNC and can check the coding related to the digispeed control? Your help is appreciated and, once tested, I'll post the schematic/layout here in CNCZone.
Stupid questions make me smarter...
See how smart I've become at www.9w2bsr.com ;-P
