My 1st machine using CNCRouterParts.com parts

[freecncplans]

I just got done building my second machine (first using Ahren's parts). I used 8020 beams, CNCRouterParts.com component setup and Unistrut for the base and legs. I don't have plans and I didn't use any. I will post a BOM materials on my site someday soon.

I used the 1/2-10 5 start lead screws and the nuts available at CNCRouterParts.com. I am using 495 oz motors on the X and Z and a 387 oz motor on the Y. The 495 on the Z was damaged during assembly and I disassembled it so I could fix it. Time to buy more motors!

I am using 4 Gecko's G201 with an Antek 50v 12 amp power supply.

Congrats on the successful build!

WOW! That's a lot of dust you've got going on there; just out of curiosity, are you using your dust hood as yet? The reason I ask is that I'm going to be operating out of my dad's pristine garage, and that amount of dust will likely get me kicked out if not killed .

I'm considering developing a completely enclosed worktable with a filtration system to encapsulate and suck up any airborne debris.

I just put it on minutes before the picture. The only thing about Ahren's setup...you must collect the dust or it will build up on the rails and bearings and lock up on side or the other. I am wondering if his setup could be fitted with v groove bearings on top and bottom? The dust is from not using the dust hood. I need to get a cyclone or seperator so the bag doesn't keep getting filled up all the time.

Other than the dust, I am very happy with the new setup using his parts. Highly recommended! I will definitely be continuing work on this machine and look forward to the day the rack and pinion is ready!

Hi Sean,
I have a router with the v guide rails (practical cnc) I use a dust hood but I still have trouble sometimes with stuff building up on the rails and causing binding. I am going to install some wipers infront of the guide wheels to help reduce the build-up. Bishop- wisecarver shows some lubricator wiper set-ups on there site. Check out what they do and "roll your own"!

Regards,

Sean,
A fine looking machine -- what sorts of speeds are you getting with those mondo-motors? Looks like maybe I should work on some dust wiper attachments for the carriages...

Hi Ahren,
Here is a link to the B-W covers.

One other note, they (B-W) also say that if the guide rail is lubricated the wear goes way down. That however doesn't help us who have mess sprayers that seem to aim for mainly the rails!

I can get 300+ IPM, but the Y screw is bent I need to get another one, or better yet, I am waiting to see how the Rack and Pinion will work (I mean price wise).

The Y axis beam is only about 2 inches from the table. I need to rework the Y to bearing and add another 1.5 inch in height to it. The Z axis is a copy of Glacial Wanderer's shown on Ahren's site. I didn't use bottom bearing block, just let the screw free hang.

I have in mind to try some tooth brushes or cheap paint brushes. I think just anything to help keep the dust off the rails. I ran a v bearing/angle iron on my Y axis on my old machine and had no problems. I didn't have the dust hood, hose or anything hooked up. If I get the cyclone hooked up and switch from the down spiral carbide to up spiral, it will be much better I think. I cut parts out of plywood and make full depth cuts.

Just as a testament to the ease to Ahren's setup...me and my neighbor built this machine in 2 days. We don't work more than 8 hours a day.

Another testament to Ahren's setup...the maintenance hours in Mach 3 say 27956 for the x, 27568 for the y and 5264 for the z. We built this machine about 3 months ago and I reset the hours about a month ago.

We had a bearing crack 2 nights ago and had to take the y axis apart to fix it. It broke because someone tightened it to much (it wasn't me...honestly!!!). the only recommendation I would make...buy the upgrade bearings as the metal shields fall off and dirt gets into the bearings. Other than this, it is a good setup.

How much did this cost you to make roughly?

I was thinking I had about $2,000 into the whole setup, but may be off on my cost.
