I am starting to rebuild my CNC router. It was made from scrap I had at the time and worked good for about 500 hours but now the light duty bearing system is wearing and I am upgrading to a water cooled spindle that is quite heavy so time to rebuild it. I decided to go with a water cooled spindle to reduce noise with vfd speed control and also allow it to run at lower speeds for aluminum and plastic. Purchased the lowest cost one I could find on amazon and made a video about starting it up. It is a 3 bearing 80mm with ER-20 collet for 1/2" or smaller bits with a matching 220 volt VFD. I know many have interests in CNC routers and thought it may be good to start a thread so others can share info about what they use for spindles on their machines and any pros or cons about different types of VFDs and spindles.
This is the setup I bought on Amazon for under $250 including the mount and I just can't believe how quiet it is with basically zero run out on the bit shank.

Hopefully others will kick in about theirs and we can help each other with integration and questions others have.

Sorry my friend. I lost interest when I saw the title, I am fed up with that ****.

I would rather buy affordable items like this then do without. I don't have 4k to waste on toys that I can buy for $200.00 to use as a learning tool. I bet all the electronics in your car and home are assembled with Chinese parts along with the appliances right down to the light bulbs. Don't like it but these are the norm for low end CNC routers and mills that most use in an affordable price range.

A friend of mine had to remotely mount a cheap VFD as the electrical noise made his controller loose some steps. One axis would creep as he cut, until he mounted the VFD over on the wall instead of on the chassis of the machine. Just a heads up for you.

Thanks I will do that. I am a little worried about placing the 400hz spindle cable in the cable chains and plan on using a braided shield over it grounded back to the VFD. I read you should not use the ground on the spindle because it will create a ground loop.

No one seems to be interested in the low cost spindles so I decided to turn this into a thread about building the CNC router it will be used on with some parts from my old one that was built from junk I had laying around and many new items. This one will be 30" x 50" cutting area that is the largest machine that I have room for. This is a video about getting started and finding a frame.

I just started looking into building a CNC router table for flattening slabs. Haven’t done much searching yet, but looking to do a 4x8 table. What do you have for parts sources?

I have been trying to use parts from Amazon for this rebuild. It's a good test to see how they last and work for my subscribers and is easy for them to buy the same parts for builds if they pass my testing. I built a larger plasma table and found many of the parts on Ebay for that. Gecko has good motor drives and 8020 has really nice straight extrusions. It all really depends on your budget and the accuracy you want from it plus the tools you have available for the build.

Just another update video. Worked out the spindle cooling using the 35 pound aluminum extrusion for my gantry. That spindle is amazingly quiet.

It's the values you live by. There's a story behind my YouTube channel name. About 15 years ago I was laid off from my last job after being replaced by H1B Visa workers. I got mad and dropped out of the workforce. After being Unemployed for a while my wife started calling things that I made Unemployed Redneck Hillbilly Creations and when I started a YouTube channel years later I used that for the channel name. Looking back now it gave me lots of time to learn new things.

Well made a little more progress. Started to machine parts and a little assembly. Decided to go with a Masso controller and it's on the way from Australia. Looks like my cooling scheme is going to work.

Got a mini Ortur 3018 CNC router to play with until the build of this one is finished. My wife wants this one for making buttons when the big one is finished. Not making much progress on the build right now. Reading the 400 page Masso manual to figure out how to hook it up.

It has finally started coming to life. The Masso is so easy to set up.

A little more progress. Electrical box done. Have the Masso fully controlling the VFD and X & Z axis's. Have the rotary axis working along with homing. That Masso controller is awesome. Found a T10 belt on Ebay to sink the Y leadscrews so that is what is left along with finishing up the tables.

Thanks. Hopefully it will be finished this week and I can get going on Christmas presents.

How did I miss this thread? Definitely looking forward to watching the videos when I have more time.
Anybody want to borrow a couple of rodents? They sure do impede getting work done.

I haven't updated this in a while but it's working good now. Here is a final video about finishing it up.

You definitely learn a lot taking on something like this.

you find you like having the sides? I have been toying with open vs closed sides for a while.

I put them there to keep dust off the slides with plans for sheet metal outer covers with bellows to close the slides in. Turns out with the water cooled spindle there is no air blowing the dust around so the collector gets almost all of it. I just spray the slides and screws with garage door screw dry lube and haven't seen dust build up so I don't think they are really required if you use dust collection. I also figured they would slow down things like flying knot parts that come loose.
-
my plan for mine is going to be a interchangeable heads for router, plasma cutter, and anything else I feel like playing with :). so I will get into all sorts of other issues. The side shields probably will make sense to keep the linear bearings from getting slag on them.
Thanks for the insight.
-
I put them on my plasma table and they don't help. It's in a 30 x 40 x12 ft tall shop and everything in there is covered with the fine black abrasive powder it creates. A water table is the best way to catch that but then you have to deal with hazardous waste. I used THK slides with double seals that still work good with constant greasing and wiping so don't skimp on your slides because that dust is very abrasive and really makes a mess. Slag is no problem because it's heavy enough that the air can't blow it around and it all exits the bottom of the cut.
-
I was hoping for a downdraft table. Direct vent outside.
So are you happy with the 2.2kw or would you go bigger? be awesome to be able to run a 3-6" surfacing bit for doing the large slabs.
-
I would not go bigger for a toy to play with in my shop. 2.2kw is about 3 hp and anything larger would require a more rigid machine plus cutters like that are in the $500 range and meant for production use. Also input power requirements to run it goes up considerably. I have more time then money so speed to surface an occasional slab doesn't mater to me. If you build a big machine size the spindle and speeds for chip loads given by the cutter manufacturer.
I built a downdraft table on my plasma cutter but did not put the pipe through the wall to be able to use it after researching the consequences of blowing a cancer causing substance outdoors and homeowners insurance regulations. There are some affordable weld fume suckers I may look into someday.
