4' x 4' x 8" Router Build

#4 Depends on the quality of the wire, the wire on the Lichuan motors we use isn't shielded and we never have any noise issues from it, only on very long wire runs ie: 8x4 or 10x5 machines do I tend to fit shielded cable but even then it's only precautionary thing and I doubt would have trouble based off the other machines we built.

I'm assuming this is something I could easily upgrade if the need arises once I'm up and running? The cables I have came with 3m extension cables, hopefully these will be long enough.

#7 We don't connect this as it's given me problems in the past with noise, if the chassis/gantry is earthed then you won't have any issues.

OK, I'll leave it un-connected. The cable from the VFD to the spindle needs to be shielded but with the shielding only connected at the VFD end and not to the spindle connector - is this correct?

#11 Permanent 24v and 5V supply otherwise you'll drop power to the Axbb-e and lose your Workoffset if you haven't saved it first, UCCNC only saves the Workoffset on shut down so if you haven't saved the offset then it will be lost with a power cut. It's also a pain in the arse having to restart UCCNC, reload the G-code etc just for an E-stop.

I'm referring to the 24V to the isolated inputs, the 24V and 5V power connections to the AXBB-E are permanently connected. Should the isolated inputs be permanent too?

Cheers
