Good morning all,
I was having all sorts of problems with UC100 having synch errors and disconnects and finally gave up on it. I picked up the ESS Smooth Stepper board from Automation Technologies (it is great having a place where you can go there and pick stuff up within an hour of ordering it!).
I swapped out the boards and got the machine running. The SmoothStepper lives up to its name - definitely a smooth pulse stream!
The only issue I have found thus far is that my spindle starts up before the Mach3 software finishes powering up. This never happened with the UC100.
I know I can leave the spindle off until Mach3 is fully powered, but am looking for a more elegant solution to the problem.
Is there a way to tweak the settings so this doesn't happen?

The UC100 had been working good for a couple of months, then it started acting up again. I have tried a bunch of different cables etc., but in the end, the problems just come back again - not worth my aggravation to deal with it any longer.
Regarding the spindle auto-starting problem
Using the same exact hardware as before (with UC100) ....
BOB: C10S
Spindle FWD: Output #2 --> Port 2, pin 17
Just simple relay control for on/off (FWD/OFF).

You have a setting wrong in Mach3, your USB cable unless your in a industrial building with lots of EMI present should not be an issue. The spindle being driven by a unshielded VFD and wiring could be an issue IF it was Running but its not. Your on ESS now, correct?
