Hai there,

im planning to buy a spindle like this...

Do you stile like it? or are there things to think about before buying??

[baccus61]

@Marcelmx3

Hey. I do like the spindle. It was a bit of a pain to set up the VFD but there is a thread in the U-Beaut woodwork forums on how to set them up properly. VERY helpful. I have also copied the information to the cnczone. Look up Huang???? forgot the name. :-(

I will buy another one for my next machine. It beats the hell out of the REALLY noisy routers and also changing brushes every few weeks.

You won't regret it and neither will the neighbors.

Rich.

@baccus61 Thanks for the great info... !

[robertsulley]

Very nice!

[mif73]

Nice work again Rich!

Hey where did you source the 12 start screw from -did you get it in Oz? - Acetal nut?

What size Spindle /inverter? - is it water cooled and are you happy with it? (noise / power / runout etc).

Have you noticed any bounce from the belt drive axis when doing fast stop starts?

Got any work for your plasma yet?

Cheers, Andrew.

[baccus61]

@mif73 I got the screw from McMaster-Carr a few years ago with the antibacklash nut. A good choice for speed and power. The belts do bounce a little when going rally fast. You need them as tight as a drum to be effective.

The spindle and VFD is from Lovehappyshopping on eBay and is air cooled 1.5 Kw. Really good so far and very happy with it. Most of the noise comes from the cutter but there are no damn brushes to change and easy spindle control from Mach3.

I bought a new collet nut with release feature as the Chinese one didn't have this and was awkward to use. $16 for 2 from ctctools on eBay. The cheapest tools I have found so far. I haven't checked for runout but there is no noticeable slop in the shaft.

I haven't got the plasma working yet. Still too much interference with the auto height stuff. The laser was heaps easier to build than the plasma was but I'm having problems with that Leetro upgrade too. Oh well !!! SOON maybe.

[mif73]

Thanks Rich,

What length and pitch was the screw?

cost much in freight?

I've seen that ebay seller and thought about a 2.2kw water cooled combo with a collet big enough to hold 1/2" shanks, but was a bit chicken to buy from china as they may not send the product , or send a dodgy one, may give it a go soon.

With the belts, I do notice they still have give in them, and can cause some chatter on Alum etc, unless you go real slow, and not too deep

Is the THC causing control noise while arcing?

[baccus61]

I can't remember the pitch but I think it's about 2" and 6' long length. I cut a but off and have some spare just in case.

The rod is now $184 and the Nut $48 from USA from McMaster-Carr but they don't ship to Aus anymore.

Try Motiontech here is Aus. They are cheap.

Regarding the spindle, I think you can specify what collets you want with the 2.2 Kw . Maybe a ER16 or 20?? Aoran Bai checks his email very regularly and I think they have a good service. They are good spindles.

THC is a pita.

[baccus61]

I think the belts are ok for wood but I think you need the added stiffness of screws if doing Alum. The multi start rods are good because you don't spin them fast enough to cause any whip and they are very accurate and smooth. You need a very hefty gantry to absorb shock while cutting metals. I noticed that small Mill Drills are now $1700 from eBay in Aus. Good to cnc the dovetail back support ones. I may get one soon.

I seem to have noise when cutting in my THC but I'm not sure, YET ! :-)

[mbr72cnc]

Very nice, what CAM software did you use to generate code? I use the same clamping system you have, wooden one don't damage bits when they get in the way.

[baccus61]

@mbr72cnc

Hi, I use delft spline systems Desk proto. It's really good and pretty fast at what it does, I think it's up to V5 now.

I would really like to get Rhino3D as it's great and easy to use. I have used up my 25 saves now so I will have to find something else to use for my tool paths. Turbo Cad does STL files but is really slow when altering them and is a bit if a pita to use for 3D. I am thinking of making some cam lock hold downs for quickness but you need to hold the wood down too

[Gollywog]

this a home made cnc? You can tell by all the shifty clamps and dust extractors you got

[baccus61]

Yep. very shifty clamps. Made them in about 5 minutes for another job but seem to work well for most things I do. I haven't got around to make some purpose built ones with a cam locking action for speed but they work well for what I want them for.

Thanks for looking.

[jdsprince]

Great job !

[kld555]

Nice job indeed :)

[sups57]

They looked good Rich.

[phillipah7]

Nice Job!

[baccus61]

Thanks. ;-)
