New build with recycled parts on a ridiculous budget 120cm*60cm work area

Looks ace mate good progress! Is there anything special needed in order to enable stall protection on the drivers? I have the same ones but only have them wired normally at the moment, remember seeing in the manual that it said it only works above 300RPM.

I soldered my CY cable to the motor wiring, make it easier for me as i was going 8 wires into 4.

Just wire the output to the emergency input on your controller board then if it's missing a step the machine shuts down. You can see it's the 2 wires for stall protection next to the direction outputs on the AM882's.

On my controller I had to wire them to a connector and then to the emergency input on my BOB as I have to cram 4 wires into 1 emergency socket, it's worse for the ground I have to cram at least 7 wires into 1 lol.

Quickie question, I'm sure this is ok

I have 3 microswitches at moment 2 on the Y axis (Dual ballscrew) and 1 on the X axis, I want to wire from the Y axis microswitch to the 1 of the X Axis microswitches in series and then to the BOB X input and the other Y axis switch to the Y input is this ok?

I would keep the Y switches on the there own inputs . Can you sketch a circuit of what you intend to do?

I've run the X axis (Gantry) to the X input and the 2 Y Axis limits to Y & Z, when I add a Z I'll add it to the the same input as the Y but will get better electronics than this BOB soon but have other things I'd rather do first.

I thought you was connecting up the home switches before. The limits can all be connected in series together.

Yes limits/home dual use.

How are you planning to use the dual home switches (Y axis in your case?). Generally you do this for gantry squaring, but only if your motion controller supports this (and not all do!). I don't think that Mach3 can do this either. I have the same problem on my own machine, by the way, and not trying to pick holes in your design. It's just one of those things that isn't obvious until you come to try to do it...

Personally, I home my dual-axis using just one home switch and manually tweak the other side for squaring purposes as my motion controller is no help at all in this area.
