It's begun....

[Washout]

Hi All,

Whilst waiting for my bed extrusions and some other components to arrive, I have been busy festooning the rack mount case with wiring (see pic below).

Stuff wired up are:
- the small PSU, which is powering the case fans (tested this and all is running fine).
- The 240v AC input, which goes to a front panel mounted On/Off switch (same kind you see on pillar drills etc)
- 240v AC from the On/Off switch to the two PSU's
- The CY cables for X, Y and Z from the drivers to the XLR sockets (shielding grounded to the star point) - I'm wiring my steppers in parallel, so am following the Zapp wiring diagram here: http://www.zappautomation.co.uk/down...%20%281%29.pdf
- The high voltage DC side of the drivers to the transformer (running it parallel off of one PSU output (hope that is right)

Still to do are:
- Low voltage DC side from the breakout board to the drivers (waiting on some lower guage wire for this job)
- Limit switch, spindle, e-stop wiring from the breakout board to the spare XLR connectors
- Find out if the earth lead I have on the main PSU is really where it needs to be, as there doesn't seem to be anywhere else to attach it to, or discard it if its not needed?
- Perhaps get some QA on my wiring, because although I am following the diagrams etc to the letter, a fresh set of eyes is always useful before throwing the power switch for the first time....

The mechanical side of things is on hold for the moment pending delivery of some extrusion channel nuts to start mounting the rails and some ali plate for mounting adapters.

More to come........
