Is a Spindle Needed on a Hobbyist CNC?

In this video, we'll go over what it takes to install a spindle and if you need one at all? As this isn't a super in-depth video ill tag videos/ articles that helped me out when I installed it. I'll also touch on some accessories and things I've been using with our Onefintiy CNC.

Fixing Spindle Speed article:

My spindle was also spinning in reverse, you can push a button on the VFD to fix this but I didn't want to do that every time I turned it on. I simply swapped two wires coming from the spindle to the VFD and it fixed the rotation direction. I cannot find where I read this but do some research before you start swapping random wires!

Etsy shops that offer Onefinity parts, I have gotten things from these 3 shops, and have been great.

Spindles
I own the 110v 2.2kw 80mm This sucks a ton of energy for 10 which is more than the basic 110v circuit can handle. I have had no issues and runs just fine for me but be aware of the amp draw of this spindle! Getting 220 isn't all that hard and I would recommend the 220v version if you want 2.2kw.

If I would repurchase I would probably just buy the 110v 1.5kw with the standard spindle size.
These are a HUANYANG Spindles, there are other brands but i have heard mixed reviews on them/ which is why I went with this brand.
I was also told the plug on top of these spindles isnt the best quality as they had one fail and reccomened this plug to replace it, I havent had any issues yet but mine is relatively new.

The link below is from PNW and the spindle is expensive but based on reviews from others in the Onefinty Facebook group it seems to work great. The spindle comes ready to cut I believe, which means you won't need to program anything or solder any wires.

Really appreciate your honesty that a lot of these upgrades don’t improve things that much.

[Kathyoftheglade]

i just have a 4040 pro genmitsu. the best thing i did for it was put a 800watt water cooled spindle. i love it. you can barely hear it run till she tears into the work.

[jameshollingsworth]

Enjoyed your direct, clear, brief explanations. All meat, no fluff. Thanks

[BoxMachinery]

A word of advice on loosening socket head cap screws, use short hex bits with a ratchet rather than allen wrenches. Also, on the VFD you can change the ramp up speed so it doesn't take long, if it bothers you, but it's best if you leave a good ramp to protect your electronics and equipment.

I'm in the same boat where I purchased the Spindle about 6 months ago but have not installed it yet. I got it wired up on the bench so now I just need to get things routed on my machine and get it running.

Soon you will be able to add automatic tool change to your table using your current VFD spindle at a fraction of the cost of an ATC spindle the Rapid Change tool racks will begin shipping July 4th 2023 if your interested I will get you one for review...

I ordered my Onefinity because of you guys!

@8:20 PD144 Should be set at 3000 for the base 50hz. 50hz for every 3000 RPM will get you your 24, 000 RPM at 400 hz. Minus some drop off... Much closer than the 11, 300ish reading right out of the factory. Note, the RPMs dont change, just the reading.

[BruceAUlrich]

Thanks for sharing your experience with this upgrade!

[WoodomainJeremyBroun]

You asked why one needs a spindle. I am fitting a 2.2kw water cooled spindle because it is quiter than a router, the half inch collet allows me to use a vast range of big cutters I have that increase the creativity of cnc routing and bypassing time-consuming programming for some operations. (See my book 'The Incredible Router'.) One problem with this heavy spindle is it dropping when powered off?

[chrisbarnes]

It's the nature of countersunk bolts like that. Once tightened the friction fit almost acts like there is a ton of loctite on them.

[dennistaylor]

Really enjoyed your video, especially when you shared what you would do differently if you were to do it again.

[WoodomainJeremyBroun]

There is a lot of useful information here, thanks.

[grumpywoodchucker]

Jeff: lot's of really good info in this video. Thank you for putting this together!!

[saltymax]

Great video! On the Allen bolts, next time you run into a problem like that, try heating them up a bit with a blowtorch. It could be they used Loctite so the bolts won't come loose.

[vittoriosilva]

If your endmill is squealing, you're going too slow ....Either slow down the spindle or increase feed rate ...Bits will wear out alot faster if your speeds and feeds aren't correct....You should be making chips not dust ....

[cd]

Screws were hard to remove because they used thread lock on them due to the softer aluminum bracket so the screws do not strip or back out.

[Real.MrJimps]

You can use a PC water cooling system for this as well. EK pump and reservoir with a 240mm radiator.

Using your Link for PWN cnc spindle! Thanks for the share

I have a Fein for dust collection. If you add a dust deputy to it then minimal bag changes.
