I spotted on another site about the motors something about these being 110v?

will try and find out

the motors won't be 110v, if anything they'll be talking about the psu input. most switching psu i've seen these days are 110/220v but some do require you to move a jumper.

one assumes if yours was set to 110v it would have gone pop already on 220v.

this is what I have mate

looks like these are the drivers https://planet-cnc.com/product/motordriver-2-5a-32/


says current selectable.... i would say there is a good chance the current is set too low.

Well bit of an update. I sent rhe pcd back to planet nd they emailed me back the day they received it saying there was a faulty bit of soldering on rhe board which they have rectified and tested. It is now back with me and I have re fitted it. This all took 3 days fir play to them foe sorting it quickly. Anyway I have been stripping the old control box to now house the stuff for the spindle motor

Here is the old box, I stripped it and sprayed it the same as the new control box as I want to mount the 2 together.


Now I mounted the power supply thing and bolted it now, I spaced it about 5mm up off the deck to help air flow, not sure if it is needed but though as there are vents on the underside it would make sense.

Now I have to find a place to fit the small pcb which has the speed control dial plugged into it


Is it ok to mount this box directly ontop of my new box so it is nice and neat? I think the power will go from one box to another so it would be much neater if the cables were kept internal hence linking the boxes?

Well another update,

I have rewired the limit switches correctly as I did it wrong the first time, I have also added ground wires to the shielding on the motor wires to connect to the star on the box I made. With the new diy motor power box I have made that is not fitted to the top of the planet box and I have begun wiring it into the planet cnc controller, just waiting on some confirmation off Planet CNC that I have wired it in correctly. I have soldered and heatshrunk the wires. Also installed a e-stop button but need to work out how the hell that gets wired in lol. One job at a time

I used to do a bit of work with a company designing drones, we started prototyping CF frames in their lab using a vac boot and a hepa filter.

A few months after that, they had a hell of a time figuring out why their pcbs for flight controllers weren’t working as intended. Turns out the little carbon fibres had escaped and were wreaking havoc all over the lab.

They had a top to bottom clean and switched to cutting in a water tray so that the CF is submerged. No problems since.

Worth thinking about if you’re going to be doing a lot of it.

I will look into that, but im mainly going to be machining resin billets
