X32 relay1 intermittently changes from NO to NC

Relay1 is intermittently staying closed after M5 command or after completion of a job, this doesn’t happen often but when it does, I cannot get it to disengage. I have sent an additional M5 command, hit abort, restarted GRBL, disconnected/reconnected, power cycled blackbox and all result in relay1 staying energized.

Anyone have an idea on what to try next??

 

It was purchased in Sept, this year, if that tells you anything. If not, I’ll look when I get back home in about 30 minutes.

 

I’m only using it turn my DC speed controller on/off.

 

Where can I find the version#?

 

Control signal, it’s only making a switch.

 

Version 1.3.

 

shouldn’t be wiring, I’m getting continuity when testing straight across the output, no wires connected.

I’ll do some more testing in a bit and post results along with Grbl settings if nothing else stands out.

 

Well, it started working "normally" again, I'll have to wait on another fault before testing.

On a side note, is there a way to enable soft stop on the 0-10V output or delay relay-1 from deenergizing? When I use M5, the spindle stops quite abruptly, surely that can't be good for it.

 

OK, I've narrowed this down a little more. It appears that what is happening, is the M5 command at the end of a job is not registering for relay-1. At the end of the last two jobs I ran, the 0-10V output reduced to ~.5V but relay-1 stayed energized ( Tool On indicator light stays on). I can manually enter another M5 command but there are no changes in the outputs. So far, the only way to get the relay to disengage and "Tool On indicator" to turn off is to command a M3 Sxxx and then command another M5. I also noted that the M3 command had to be from the "Variable speed spindle on" selection and also had to be a value less than M3 S12000 ( 12,000 being my max RPM), I mainly used M3 S6000 to accomplish this. Settings listed below, maybe I'm just missing something.
