That looks perfect. Am I correct in assuming when I create a toolpath in Aspire with a set spindle speed(e.g 10k) when its opened in Mach it will set it to 10k for me?
I feel daft asking these questions.
Thanks, Phil

Assuming you have all the speed control hardware that is exactly what you get, its another control you can forget, it takes a little setting up but once done you forget it..Quote:

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.Quote:

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 :)Quote:

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
80 diameter 2.2kw WATER-COOLED SPINDLE MOTOR AND INVERTER VFD DRIVE four bearing | eBay
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

Like a new car it is worth running the bearings in before loading it up at full chat.
In progress now, its running at 10k and has been for 15mins so far, will give it another 15mins.
Cheers
FYI 2.2k spindles and vfd are back in stock in the uk. Price has dropped too.
Thanks r0bsk1 for posting this I will check eBay now.

Damn my hastiness, I bought the cheapest one from aliexpress a few days ago and it was £8 (plus £1 bank charge) more than they're now selling them in the UK on ebay. Plus the seller has dispatched it with FedEx even though I chose DHL as the courier, so now I'll get a nice admin charge from them. Oh well :boxing:
I'll post again when it arrives :courage:
Hi guys. What do I go for a four bearing one from uk or 3 bearing one from chai?? I can't decide
Still looking at spindles on eBay and unsure. Had a good price off chai but with shipping takes it up a fair bit.
There's one via solar.jean which I am tempted by, is a four bearing model but only has a 3 pin connector. Is this an issue? Can an earth still be fitted - does it need one?
You could easily change it for a 4 pin connector, or just fasten the earth cable to the spindle body via the spindle mount or tapped hole in the Z-axis, assuming they're all metal.Quote:

just buy it!. it'll be fine.
I'll post some pics of the one I got from the aliexpress link if anyone is interested?
Yes please & thanks Jonathan
OK, here we go.
3 pin plug
Other than that I have no idea about the rest of it, not fired it up yet as I've been feeling too ill.

Don't know how many bearings it has but it is much heavier than I thought it would be. Hope the gantry is up to it! VFD is the usual Huanyang one and hope the modbus works in it. Also supplied with 4 collets 4mm,6mm,8mm,12mm, 1/2" and spindle connector plug. Will try it out this week before giving feed back on ebay and will post some pictures here.
Thanks guys for this thread and all the help with the CNC Mill design. Building starts soon

Slightly off topic but does anyone know where to get replacement water nipples for these spindles?
iv been to my local pneumatic/hydraulic suppliers and they couldnt help.
any ideas ?
Dave, I'll check what's fitted to mine and have a look.
You stand a good chance of being in luck as I have just today throw two buckets of unions into the van to weigh in tomorrow.
Quite a few are new, probably a bucket full but got that much crap I have got to have a clear out.
What size pipe did you want to use as If they are what i think then you get a choice of 4mm pipe, 5mm, 6mm, 8mm and maybe 10mm
On my spindle they were a metric fine pitch thread, so not something I expect would normally be use for plumbing. I was once a bit too enthusiastic with the spanner when tightening mine, so I just made a new one on the lathe. Can you check what thread it is in your spindle?
Yes just checked and not 1/8" gas which is what i expected, so sorry . can't help.
yeah the guy in my local pnuematic supplier couldnt find anything off the shelf. its nearly M8 but not quite.
as Jonathan says its probably "M8 fine" but as i do not have any thread gauges so i carnt be sure.
i dont have a lathe that will do screw threading bit if it comes to it i will have take it apart and drill it out and re tap it 1/8 BSP.
Some of these have NPT fittings
Mine looks to be M8 or around there.
How many fittings do you want, got a few 2.2Kw spindles here that I'm not using at present and i can rob them to get you out the sheeite
Just checked the two I have - they're both M8x1.0.
The one i have is M8x1.0 also
thanks guys i only need one to replace the one that snapped off.
I would be most greatful to accept one from any of you. ( i'll let you fight it out amounst yourselves :untroubled: )
i assume you can PM me for details ( i can send a self addressed and paid for jiffy bag )
I have just bought a spindle from here happykisssoul:-
WATER COOLE MOTOR SPINDLE 2.2KW VFD MATCHING INVERTER ENGRAVING GRINDING l7 | eBay
£214.95 inc del. All seem to be ok and well packed ...Clive
Hi Clive you got a better deal than I did at £221 but I'm not complaining!. Thanks to everyone on this thread and Lee for making it a sticky. Finally got it all wired up and set the PD functions as advised by Jonathan and hey presto it works!Quote:

1. Read the manual
2. Fit crimp on spade terminals (2.5mmm blue) to your wiring when connecting to the VFD. It gives a solid secure connection.
3. Use 2.5mm2 mains lead to your VFD.
4. Use good quality shielded cable between the VFD and the spindle. I used SY cable 4 conductors at 1.5mm2 which I got for an amazing price from a local Commercial Cable Supplier. Earth the screen at the VFD end but not the spindle end. You can electrically earth the spindle by connecting up the 4th pin at the spindle end but you will have to take the end-cap off to make sure you run a wire from the pin to one of the bolts that keeps the end cap on the spindle.
5. Use shrink tubing on the wires inside the spindle connector to avoid shorts. These wires are soldered.
6. Read the manual
7. Check all connections for correctness and shorts before powering up.
8. Set the pd function values by pressing the "PGRM" button, then the ^V buttons to get to the pd function you want then "set" to display and change the values by using the >> key. Then Set to save the value and exit. This bit took me the longest to work out!
9. When all set then RUN to test.
If I've made any mistakes in the above please let me know. As I said the hardest part was knowing how to enter and change the pd values!

Mike
Thanks for the heads up on the info. Re the earthing I replaced one of the scoket mounting screws with a longer one (3mmx30mm) so it went right through and stuck out inside then I soldered a cable on to pin 4 of the socket and soldered a ring on the other end, I then put this over the screw on the inside and locked it off with a washer and locknut.
I am using 4 core .75 cy cable (55p + vat) from here Cy Cable Per Meter 4 core but not got around to testing it yet. ..Clive
Attachment 9309 just thought id share, I had a problem with a cracked fitting for the water cooling on my spindle and found these things fit and work ok. It's called a banjo and can be found on eBay with the correct thread fitting of m8x1 also makes cableing neater as all the pipes and wires run nearer each other.
Could somebody post the spanner sizes required
1.) for the er20 collet nut
2.) for the spindle shaft (used to hold spindle still to unwind collet nut)
obviously these spindles dont come with the spanners, so Im just trying to order some... but im at work and therefore not near my spindle
