I installed a IOT relay to operate my dust collector and I can get it to start with M8 and Stop with M9 but when I run a file the dust collector shuts down after 1 or 2 minutes into the cut. I used 16 gage wire and connected the IOT to a separate outlet but still no luck. Is anyone else having this issue? If so, any recommendations would be appreciated.

Hey Lyle,
Without knowing your machine, controler, what gcode software and what iot switch you use or how long the wires are between the unknown io of the controler, I can only speculate you could have some static ghosting your vac.
You could try to run the iot without the vac running and see if that keeps the switch in its on position. If not, try running something in the air without running your router/spindle.

@LWH Can you post the gcode for the file?
This was my thought as well - does it run without shutting off when not controlled by the IOT.
I had a smart switch on mine that would shut-off periodically as it ‘exceeded’ the current threshold. It didn’t, or rather shouldn’t have - I replaced the smart switch with a different brand and all is well now.
I don’t use the IoT on the SLB though, I built my own controller.

Not sure if you are using the SLB or not but I had the exact same thing start when I upgraded to the SLB.
Chris T. @ Sienci reached out to me via e-mail and suggested I try using the SLB’s ‘Aux PWD 2’ to trigger the relay as a test. It’s 24v but the iOT supports that. That resolved my problem so that’s where I left it.
The following is from the SLB’s technical manual and it explains how to use those ports. By default they are configured to turn on and off with M8 & M9 but you can change that if you want.
During my troubleshooting I discovered that the issue didn’t happen initially, but then did happen sooner in my carves once the SLB and vacume had been running for a while. I also found that if I didn’t have the iOT trigger cable connected to the FLOOD port, the port and it’s corresponding light never turned off. It kind of looks like that there might be some overcurrent/ overheating issue.
I also found an older Sienci forum post that reported the same sort of thing. My SLB is one of the original ones.
@chrismakesstuff FYI…
