Whilst I wait for the psu parts to arrive, I was thinking about the driver fuses. With the current setup, if one fuse blows on say the z axis, the other axis will just continue regardless, potentially damaging the part or even the machine. Is there a software or hardware tool to stop this happening?
Would a 3 pole fuse holder work? Or is each fuse still independent of the others?
What drives you using.?
Each fuse is still independent.
You might be able to detect an unpowered driver with a properly configured fault output and a controller that is checking for this signal?

Nice, looks like you making good progress:)
Just stumbled across this on YouTube and thought it was worth sharing. This guy cuts aluminium on a 3D printed MPCNC better than most videos iv seen from people with a "propper" diy cnc router! Mighty impressive!
Hope my machine can perform even half as well as this.

Very impressive! That just goes to show how important it is to spend time learning how to use the tools you have to their maximum capability.
I'm certainly tempted to try out my router on aluminium. I hadn't really though it was up to any serious work it until I saw that.
It's the adaptive tool paths that allow him to get away with it as they take very lite cuts but at full depth. If you notice when profiling using typical profile toolpath he was using a very small depth of cut(DOC) and feed rate because the machine wouldn't be able to handle taking correct DOC to suit the tool diameter. However Still impressive to say 3D printed.!Quote:

Thinking of building a small wooded cabinet for all the electronics, maybe with a plexiglass window if I can keep my wiring looking nice and tidy. Are wooded cabinets considered safe?
I don't think theres anything wrong with a wooden cabinet - plenty of people do it. I think metal is probably better at keeping moisture out, (electrical) noise in, and means anything that manages to go bang is contained by a strong earth-connected box, but its probably overkill for many of these machines. From a financial perspective, my metal cab certainly wasn't cheap, and I'm pretty sure its not going to add any functionality to my build. I have a sneaking suspicion mine is mainly for aesthetics....Quote:
