The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

[Ricardoco]

Main thing is you require a breakout board that can handle 0 -10v analogue output for the speed part.
Many BoB's have spindle relays, not many have the 0- 10v part.

I think he is being pointed toward the usb > serial (RS485 i think) lead from PC to VFD that does the control with a plugin for mach, not tried them so couldnt comment.

I was indeed, my BoB with PWM is in need of repair so I bought a cheap ebay job that is actually pretty good only no PWM. So I will use the RS485 converter(I actually had one for some reason, past project I guess) and see how I get on. Next is finding some springs to counter balance my Z axis :)

Can the UVW go in any order as long as it spins correctly or do they need to go to the correct pins? I have the earth from the spindle going to E is that OK? Do I need to use all 3 wires from the mains or just the live/neutral? I'm close to testing it out now :)

Live and neutral go to any of RST and both earths goes to earth. UVW in any order is fine, so long as the spindle runs in the right direction.

for those saying the cost is massive at the minute, i'm still finding 2.2kw spindles with vfd's for £252

yes there are some more expensive, but theres plenty in the £252 range as well, admittedly they are all from solar.jean

I've connected the shielding to eartch at the VFD, I assume its the correct way?

Also, would these VFD settings work with the 1.5kw spindle, I cant find the bit of paper that came with it :)

Thanks, Phil

Managed to sort it, fired it up and its sweet. One thing thats bothering me is at 24k theres almost like a rattle inside that sounds like a bad bearing but drop a few thousand rpm and it vanishes.

Good points are when it was running there was 0 vibrations on the kitchen counter and it sounds good although its going to be a while before I get used to the different sounds at different ranges, I'm used to it just getting loader :D

Cheers, Phil
