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

They were the right connectors from rapid online, just got some cable for the signals but still waiting on the CY cable does mean though I can wire the BOB over the weekend, connect the power supply, PC and parallel port so easy job when CY cable comes.

Looking good mate!

I especially like the blood at the bottom of the case (Mine of course)

Decided not to go back today was sent some drawings from a solidworks designer and not happy at all I know I can draw them better in Fusion how we want them but not sure how lol.

Taking a while to get used to not having a co-ordinate system anymore and working from offsets but I'm hoping if I keep my head down I can get the drawings finished today.

These things don't work without a blood sacrifice...

I think in the old days you used to sacrifice someone else's blood.

Started the wiring today ;) Only going to wire up 2 of the stall protections for now (For the dual ballscrew) once it works we'll add in the other 2.



I'm guessing the plus/minus dir don't matter which way round they are wired and can be changed in Mach 3/LinuxCNC

Finally skanked a 2nd hand piece of ply to use for shelves almost having to go buy one there :)

Wired up a little more, now I need the CY cable so I can wire to the motors, limit switchs will go on last as I haven't even decided how to mount them yet past a brief look around the machine for ideas.

I think I might need to use the machine to make the limit switch mounts as I want them to be rock solid out of aluminium rather than 3d print them.



I hope I wired the emergency in correctly (Only 2 of 4 wired in at moment) wired them to a barrier connector block joining the live to live and neutral to neutral than ran 1 wire each to the right inputs on the BOB.

I assume it's similar with the limit switches, wire all the grounds to 1 connector and then from there to the common ground (same as emergency) then wire the limit lives. X&Z to the X input, One Y limit switch to the Y input and the 2nd Y limit switch to the Z?

I did ask before but forgot the answer what power should I feed the BOB


Looks like theres 2 PC live 5v's inputs, with 1 gnd, also 12-24v input and a 5v USB? Which one should I use? I'm going to have this sat next to the pc that will control it and I'll get a 4 pin molex extension to tap a spare output from the PSU so will have both 5v & 12v available.

5V comes from USB, 12 - 24V - external PSU. Same BOB was used on my previous Emco lathe.
