Now for the electronics :banana:

[RMHCNC]

Well I have wired up the electronics and started cutting the parts I forgot or just had to wait till the unit was reassembled,with the upgraded parts the spoil board is alot lower. so I need to design and cut a new spindle mount plate
Here is a pic of 1 upgrade part

Another upgrade
Still need to mount my spindle

Well it's time to take the plunge and buy a 2.2k spindle.
I'm on the fence as to what I should get. Not a big diff in price on the water cooled and air cooled units
Mind u it has the extra cost of pump and misc parts and pron to leaks
I hear that for the hobbyist air cooled is fine but if im going to benifet from water cooling I may as well spend the extra $60

[RMHCNC]

After a lot of post reading and hmmm/haaaaing I have went with this
http://bit.ly/17Ks0tW
I just hope the sellers reputation proceeds them

[Flateric]

I am leaning towards the very same package. I wish the auto-tool changer spindles were cheaper but it is unlikely to occur within my lifetime it appears.

I am wondering as to the benefit of going larger or if the 2.2 is the sweet spot for these chinese spindle packages

I have seen larger 3k spindles but then the price seems to sky rocket
The price listed is not what I paid, little cheaper as you can also make an offer before committing to buy.
The reason I went with this seller was their reputation and support, same day responses to my questions
Will see how fast they ship
Also 2 year warranty how good not sure yet and let hope I don't need to find out

I am real happy with the spindle I got from him, went with the 4 bearing 2.2 kw water cooled and Hitachi vfd, been running daily for well over a year with no problems. Still sounds new, never gets more than a few degrees over ambient. Used a pump and radiator out of a powermac g5.

That was what I was hoping to hear
I got the cheep VFD but have bin told they work fine just a pain to operate due to poor litature
A few chaps have offered their help setting it up, should be fun

[Dylwad]

The only thing I did to the spindle was replace the plug on it with a much higher quality, but still Chinese made "mil spec" version and made sure it had a good ground.

I disassembled it to check the bearings and general quality and fit and it was all good, so probably no need to take yours apart.

Funny I have bought multiple collet nuts from various vendors, some Chinese, some German, some US made, all claimed to be balanced, and none of them run as smooth as the nut that came on the spindle.

Lol I was just looking at your thread as you posted
Very nice setup indeed, did you make and mill the mount yourself?
As for cooling I plan on doing the same and using a PC master cooler.
I order my collets off eBay from this seller http://bit.ly/18FHPTR
all ER11 as of yet but just ordered 1/8 for the new ER20.
I'm no pro CNC at any turn but good prices and fast shipping

I made everything but the actual spindle mount with my machine using the 2.2kw spindle and destiny tool viper endmills for aluminum (carbide plus on Ebay, great seller).

Used the dust collector and a silicone spray lube/non ferrous coolant from precisebits in a spray bottle. Mic6 makes small chips, not long stringy chips, so recutting chips isn't as bad as with 6061.

The mount is from k2, and was like finding hens teeth at the time. I upgraded from a Bosch 1617 with precisebits collets, world of difference!

I use techniks and maritool collets, if you smear a tiny bit of anti seize between the collet and nut faces the nuts will pretty much last forever, otherwise they will gall.

I have a crow foot wrench I use in a torque wrench to find the optimum collet nut torque for low runout when using 1mm and smaller bits in carbon fiber sheet. It can vary up to .002" just by how much torque is applied. The spindle bore doesn't make my .0001" indicator budge, it's pretty much dead on.

Oh and I got the powermac G5 cooling system for $25 shipped on Ebay used. It runs 24/7 and I have a flow meter to make sure it's running.

Right on Ty for all that great info!
I hear great things and follow a guy on Instagram that put me on to destiny tools endmills
Awesome chap for sure, just waiting on some tester mills he is sending. I was having and still am a lot of trouble
milling Delrin so he is helping a noob and pointing me in the right direction.
What RPM do you find works best for aluminum

[Dylwad]

It depends on the aluminum and bit size. From memory mic6 was 12000 rpm and 40 ipm, .07" doc. 1/4" bit.

I mill a lot of delrin, but usually tiny pieces. I use 1.6mm 3 flute 0 helix and the edge finish is great.

[RMHCNC]

Again Ty
I was using a 1/8 2 flute endmill and it was not made for plastics at all.
With the new spindle and Destiny tools endmills I should do a lot better I hope.
I also need to find a place to make a mount for me as my current spindle is dead.
The mounting plate I made is 3-1/4 " wide so I should be able to design something just getting it made is going to be the pain

On another note I need to get my hands on some better cam/cad sketchup and plug-ins are limited and the code generated is poor
I'm not knocking it for free a guy can't complain

[RMHCNC]

Well I ordered a 80mm spindle mount from CNCRP, looks well made and will fit perfect I hope lol

[RMHCNC]

Dylwad what gauge wire did you use to connect from spindle to VFD
I was thinking 16 awg shielded but just wanted to see what ya used

[Dylwad]

I used intercond 1.5mm shielded, around 15 gauge, just because I had it. (expensive italian wire used on SCM machines) 16 gauge shielded will be fine.

The good stuff, continuous flex rated shielded 16/5 from mcmaster, 7673k49 is $4.15 per foot and is probably what I would have used if I had to but it new, or the spindle cable from ugracnc for $2 per foot if trying to save some $$.

You rock man Ty
Spindle and VFD showed up in great visual condition, now for the fun.
My cooler and pump should be in soon
