Compressor motor turning on and off is cutting out my cnc spindle

Paul,

Much depends on your level of experience and your ability to pick a soldering iron up the right way



Firstly, disclosure - I have a UC300ETH, however, I'd recommend the AXBB-E. Basically the brains of the UC300ETH coupled to a pretty robust break-out board (BoB). If you don't do this, you'd need to source a BoB anyway, and a 26->25 IDC header cable (at least!). It's just more faff. Another thing though - I'd examine your control box to understand the space envelope you have to play it, or, work out if your want to adapt of replace the control box (just the physical enclosure). Quarts don't fit into pint-pots, and recent experience with another's 6040 indicates the control boxes can be a bit pokey. Your experience may vary.

Before seriously considering this - have a look in your control box and get a photo of the innards and post here - we'd have to understand if you have separate stepper drivers, or integrated onto the controller board. If the latter, you have a steeper cliff to climb. In principle the control box is very simple in design, but implemented in any number of cost-cutting ways, so it's hard to advise anything without eyeballing what you have.

This is very common with compressors, esp with USB, back in the stone age long before Ethernet controllers where common I had the same problem with one of the first USB Smooth steepers from Warp9. My compressor was outside on the opposite side of the wall in the compressor house however it shared the same ring main as the PC. The fix was to hack the cable shield which was causing a ground loop and lot of messing around, but even then it was never fully stable. I wouldn't ever use USB for a CNC controller as it's far too unstable.

Regards UCCNC or MACH3 then I'd go with UCCNC. As most on here know I've been a long-time user of Mach3 and have built or retrofit fitted 100's of machines that use it and various controllers that work with it. However, I've recently made the decision to soley use UCCNC and AXBB-E or UC300ETH/UCBB boards on all the machines I build from now on. The reason for this decision is because Mach3 is no longer supported and Mach4 is full of bugs, Also the controllers are very well built and the UCCNC software just gets bettter and better.

Now I was going to create a thread to say this but I'll mention it here in case it helps you. I'm buying the AXBB-E and UC300ETH controllers in bulk for the machines I build/convert and I'm happy to sell to forum members to save them the hassle of importing etc. I'm also doing the same with Lichuan Closed loop steppers and drives.

If this interests you then get in touch via PM.

Heres what Im working with. The current controller is approx 110mm x 60mm. I like the sound of the AXBB-E and will gladly switch over to UCCNC. Tried to make a simple fixture today and it cut out about 30 times, becoming very annoying.

The AXBB is 120mm x 97mm so it doesnt look like it will fit where the current controller is but could I just mount it in that spare stepper drive slot?

I should add, UCCNC will impact Mach3 settings, as well.

EDIT: Urgh. I feel dirty just looking inside that box - Get Henry out!

Mounting the AXBB-E where you suggest is fine - if it fits, but will be a ball-ache to commission/maintain etc. with limited access to terminals. Personally I'd look to see if there's height available to mount a plate above the stepper drivers to fix the AXBB to - so you present all terminals immediately under the cover in an accessible manner. But running before we can walk...
