Hi. I recently had an issue with arming the HiCON Hobby board and I figured I'd mention it here in case it is useful for others. I also have some questions which I'll mention at the end.
System Info:
Mach4 Hobby Build 3233
HiCON Plugin v2.01.47
HiCON Firmware 3.46
Windows 10 Laptop
Problem:
While adding another axis via the HiCON plugin I suddenly started receiving communication errors, the motors stopped turning and I eventually received the failure to Arm error.
My Fix
1. HiCON Hobby shipped with firmware 3.47 which I flashed back to 3.46 which did not solve the problem.
2. Out of desperation, I opened up the manual and double checked all of the plug in settings. It appeared that I somehow lost a bunch of values and didn't know it.
3. On the System Tab I set:
Max Buffer: 100
Polling Frequency: 100
4. On each Motor Tab:
Control Input Source: MACHXX
Control Input Index: 0 (or 1 or 2 depending on the tab)
Control Input Gain: 1
Control Output Type: Stepper
Control Output Index: 0 (or 1 or 2 depending on the tab)
Feedback Source: StepGen
Feedback Index: 0 (or 1 or 2 depending on the tab)
Feedback Gain: 1
Feedback Max Following Error: 100
Once I applied these settings, everything started working again.
Questions
1. What is the correct Feedback Source for a closed loop stepper system that DOES NOT deliver encoder data to Mach4?
2. What is a reasonable Feedback Max Following Error for a closed loop stepper system?
Thanks,
