I accidentally selected M7 instead of M8 on my device settings and now Air Assist is not working. Have I fried the pump or is there any way to troubleshoot this issue?
Thanks in advance
Coincidental for sure nothing in the M7 command could cause that
You can set it back to M8
Power off the machine and power back on
Confirm if the pump works by manual controls (if it has them uncertain on that machine)

Crap must have failed then its not working when select M7. The pump does not have a on or off switch. It connects to the control panel directly. I may break out the meter tomorrow and see if its getting current.
Dig into the documentation to see how it activates via commands So you can issue them yourself
but 99.9% sure it was not swapping the air pump commands in lightburn that caused it .

Looks like it is fired by M8 but I put my voltameter on it this morning and the air pump does not seem to be receiving any power. I am going to open the little case and see if I can send 24V directly to the side that is after all the circuit stuff. I also checked the supplied power source and see it is not delivering 24 DC it’s more like 23.6 DC or something. I wonder if it’s a case of not being supplied enough power. I guess that is probably not the case as it was working before.
Good findings
I would in parallel seek guidance from Manufacturer on what might be the cause.
I wouldn’t think so, but - never know how “don’t open” might affect warranty things.
I would suggest as well seeking their user official group on Facebook,.

I don’t think that would be a good idea. If you back drive 24V to circuits that are not ready for it, you could fry the board.

Good point…I will just use my old manual one until I see if its the pump or an issue with my board.
How about a logical approach?
M7 and M8 are listed here and may help you if you have configuration data available for your sd card. There is little here, but it tells you have these are handled.
If you’re reading 23.6V on 24V input, that should be ok. I doubt 0.4V under will have any effect. If it’s getting 24V, then I’d suspect the compressor…
It also might depend on how you measured it… Some of these have 24V on them, the controller then complete the ground to turn on the device. It may not switch the 24V, it might switch the ground.
Doesn’t really look like you could have broken anything… I’d double check the connections before assuming the worst… been there done that 
You can remove the connection to the controller and just feed the compressor 24V for testing.
Good luck

Thanks for all the help and suggestions. I spoke with Longer and explained my troubleshooting with the voltmeter. Based on the new firmware flash and issues I am having they are sending me a new mainboard. I will report back once I get the new board installed. So far their customer service is amazing.
