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

You are going to have a problem with this bob because you won't have enough inputs to do what you are trying to do.
for instance that bob and most simple bobs only have 5 inputs. You will need two for the homing for the slaved axis. Then you have all the limits they can be wired in series to one input that leaves two. you have to home Z and the other axis. So the probe is out of the question.


The E/S button would not be connected to the stall on the EM882 This should be cutting power to the drives power supplies etc. though a contactor or whatever.



The 12-24v power is for the inputs and the 5V is to power the BOB. connect the two power -ve together. I would not use power from the usb for anything.

If you are using linuxcnc I would download the 2.8 master branch and get to see how it works. Also I would connect one thing up at a time and see if it works as intended then move on to the next problem.

I ordered a 2nd BOB and PCI parallel port card would this give me the extra inputs I need?

I was going to run 5v from a molex connection on the PC PSU to a usb plug would this be ok? I assume you just don't want to use a real usb port on a pc the connection itself is reliable.

Not worried about probe for now I just want it to work I know that at some point the BOB will have to go in favour of a proper controller but we can worry about that after xmas ;)

If I don't stop spending money on this router soon it will be a crap Xmas lol.
