Building My First CNC Router, Looking for Advice & Other Info

I was considering filling the extrusion with resin but I asked around the forums and was told it was a waste of time.

I also spoke to a fibreglass guy who told me to use polyurethane with metal filler.

In the end not going to bother this time but will consider it in future.

I did some digging and came to same conclusion, think i will make the bench very heavy duty and fix the machine to it.

Havn't had as much time as i'd hoped the last few weeks to get much done, got all of the stepper wiring done, the cable drags turned up which meant i could get the lengths correct for the cables. I now have all Axis moving which is a nice milestone in the build. Ordered some Inductive Proximity sensors to act as limit switches, they seem to activate about 1.5mm from Aluminium, which should be ok for me. I need to do some research on the controller, as it has Terminals for Min, Max & Home for each Axis, what would be the scenario where you would have Home different to Min? Do some machines have Home at the Max or maybe Bed Centre?









Also need to order some Screw Connectors for them.

Got the Spindle wired in also, just need to configure the VFD properly, watched a few videos online which seems to be simple enough.

Also got through EMI / RDI Ferrite Rings for the Spindle cable to try and help reduce interference from the Spindle / VFD (whether it will or not who knows).

Current task is designing a portable enclosure for the DDCSV controller and the Parallel Breakout Board, i got two breakout boards, one to on the Electronics Enclosure and another to go with the DDCSV in its portable enclosure.

Have you thought about the switches, the way you have them is asking for them to get squashed they might be better mounted so that they slide over the target

Haha don't say that and jinx me :D - Do you mean so that they would be similar to how I have done the Y Axis ones?



Thanks

Exactly. You have the switches ready to get squashed

Thanks, i will try and re-work those, at the moment those positions were the simplest and gave the maximum Axis Travel.

Thanks
