I'm are getting an Error code when trying to enable in mach4  "unable to ARM drive (code=355)"
 what can cause this error to come up? the hicon card brings in the error light as well.  bringing up a bridgeport CNC (1980's model). i will list specs below

3 axis bridgeport series 1 CNC ( 56v sigma stepper motors )
Hicon intergra 7766
Gecko drivers G203V
24V/5V Power Supply (P5-RD-35B) 
mach4hobby with 3 axis profile (Mill3Axis-Integra with wx4_VSI.set)
running lasted Mach4 plugin ( Mach4_Integra_010217 )
spindle runs as standalone currently
windows 10

i have been using these PDF's as our guide :
Integra User Manual
Mach4 Integration Manual
VSI Device Manager Manual

i have mapped all limit switches for X,Y,Z
mapped Z home switch (X,Y do not have limit switches yet)
enable motors in mach4 for 0=X,1=Y ,2=Z
setup config in Hicon plugin
setup Mach4 config

chime in if anyone can help with this

could This be caused by my step and dir wires. for example i only have one step wire and one dir wire.
for motor 0 im landed on +sp0 for step  and +DR0 for dir

Looks like we were able to resolve the issue over the phone by providing the necessary system activation. The unit accidentally lost the "Arm Enable" activation during a firmware program with an older incompatible firmware version.

We'll look into that more, but firmware 3.46 is the good firmware version for your unit.

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

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.

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?
