First Build 5 x 12 Steel Frame CNC router

Strange because Usually very straight forward provided you set Network adapter manually it works.

So have you set internet protocol version4 (TCP/IPv4) address manually.?

Yeah 10.1.1.1 was entered manually into my computer. I pinged 10.1.1.2 when reaching the IP/A.

Couple other things I tried, I made 2 new rules for the CSMIO firmware software and Mach3 still no luck.

What I am assuming at the moment, I am using my work laptop as that is the only computer I currently have, I bet it is something with my IT policy on the machine that is blocking it (other than windows firewall). So time to pull my old desktop out of the rafters and get it back up and running...

Still on the search for a good enclosure for the electrical components. Anyone ever put the spindle motor vfd on the gantry rather than run long VFD motor cable to the spindle? I was thinking about do this to keep the 3 phase cabling (higher current to the spindle at least) as short as possible. I think some of the big CNC players do it this way where they have a control cabinet on the backside of the gantry. Thoughts on this?

Thanks
Scott

I was contemplating this many times or to integrate it in the machine somehow. First the dust will be a problem, but you could make a cover for it. Biggest issue for me is if cable disconnects and touches a metal while i am touching that metal too. though the machine must be grounded. I don't know. there must be a reason not to do it. It has some vibration requirements also.

Do-able but involved and costly.

Dust and Vibrations are the biggest issues. Cover the VFD and heat becomes an issue so Good Filterd cooling is required. Vabration over time can cause issues so it will need mounting on rubber standoffs.

I would not do it - if this is a single phase input/three phase output VFD then the supply cable will be carrying more current than the motor cable. As mentioned, vibration and muck are serious enemies of electronics.

Thanks for the thoughts on mounting the VFD to the gantry. I had kinda thought about those items as well, the main driver for me was actually 3 phase switching noise caused by the VFD. I use double shielded VFD cable but at these high frequencies (300 - 400Hz AC at 2.5khz switching) there can be alot of noise that causes interference elsewhere in the home. Anyway I have scrapped the idea in favor of wall mounted.

Finally some updates on the machine.





X axis motor mount plates (laser cut) and servo motor mocked up.




Long ballscrew mocked up for bracket design



Also made some good headway on the electrics. Still cant get CSMIO to connect so will have to contact them here soon but Im a bit of time away from needing it.
