Miles of space for sure - all that really needs to come out of it frame wise is the CD/DVD/Zip support that runs the full depth of the case, only pop rivetted in so that was easy.

My problem now is the actual wiring, I'm a tad confused - I can see where X, Y, Z, the E-Stop, switches, mains power goes etc but the original PSU is not connected apart from a 24v plug and one that says PWM to the yoocnc board. I'm guessing I'll need the one board (the lower one) but I'd really like a knowledgeable comment here as I'm not in the mood to blow the new stuff up.

The attached image shows the following things as marked OK - I've sussed them out, what's confused me is there are two power connections, 18v and 36v plus the 24v going from the one board to the other.

If I do need to use the lower board, do I make the 24v power cable a three way split for each stepper?



Pity they had to make the X,Y,Z wires all yellow and white - cheap swines!!!

After being flat out making stuff with the cheezoid yoocnc setup I finally decided to get stuck in to building the 542 with bob box - the main reason being the yoocnc went tit's up (spindle won't stop spinning) so with that said I got the 542's wired to the bob, I can see where the e-stop, limit switches etc go, where the X,Y,Z wires go but what about the spindle and or spindle power? The only other free connection says 'relay' - or is the spindle powered by the 5v???

These are the bits I bought, gunna make use of my existing PSU which looks like the round jobby - 3X M542 CNC Stepper Driver FOR NEMA17 NEMA23 NEMA34 Motor 5 Axis Breakout Board | eBay

Looking at all that has me none the wiser so any help wiring it up would be much appreciated.
