I have recently enclosed my plasma table, and setup a fume extraction system. That all works awesome. The metallic dust is also mostly contained within the enclosure. There is a lot. After cutting I’m getting dust sticking to the top of the z axis stepper. It’s also going inside the hole in the top. I assume that hole has an encoder there. Is it open to cool the motor? Would it be ok to plug it up with something? I’m going to move the control box out of the enclosure as well.
That metal dust is getting into and on everything there. Controls, plasma cutter, bearings, wiring, everything. If you don’t keep it cleaned out every day or so it will start causing all kinds of trouble. If your plasma cutter is in there the inside most likely will be full of the metal dust and will short out the PC boards soon.
I’ve got the plasma cutter out of the enclosure. It’s up on the wall. I’ve got cables on the way to get the electronics out as well. I’m going to try and vac out the dust out of the stepper. Maybe cap the hole. I’ll see what support recommends in regards to caping the holes.
Could you place a deflector or “cone” type cap on the motor. Instead of plugging the hole this would just keep some/most all the dust away from the motor.
Could you use a piece of a cleanable foam or a disposable paper filter wrapped on the top…
