1. I added an ESS board to my hobby cnc mill to eradicate some pc/noise issues and I have everything communicating and with stepper control. I made a new Mach3 profile and set about changing some stepper directions and the ESTOP port issue - all done. I'm aware I've unexpectedly missed-out on the process of configuring the ESS for stepper frequency, etc, and despite hours of seemingly going over the same process with the 'configurator', can't get to the page to do this. I've added and removed the jumper for BOOTP many times, powering up and down before/after, but running the configurator doesn't bring up this page (should it??). Ethernet adapter is talking to the ESS, so IP addresses are OK, right?
2. I'm also needing to revise my steps-per (mm) figure in Motor Tuning, and I'm pretty sure I had a figure of 2000 working before the ESS was introduced. HOWEVER, with my setup as follows:
- Direct stepper connection to leadscrew with 5 TPI, so one rev = 0.2" or 5.08mm
Standard steppers with 200 steps per rev and x10 microstepping = 2000 pulses per rev
so dividing 2000 by 5.08 I get a 'steps per mm' of 393.7.
this figure works for axis calibration but how could it have been working with 2000 'steps per' before? (If indeed it was, perhaps I should up-the-medication.......)
Any reassuring words will definitely help!
