Joe's CNC Model 2006 (Mods & Additions)

[joecnc2006]

I thought I would open this Thread to Be able to have all the Modifications and Additions to the Machine so it would be easy to find them in one place instead of stumbling onto them in all the different threads.

Ok, I guess i will start if off with just a brief list of mods to the machine.

1.) sanding the pipe rails. (this helps with smoothness and cuts on the machine)

2.) I added threaded rod through the sides of the gantry across the the Y-Axis. if i remember right they are 14.5" from the bottom. I also added threaded rod just above the Lower Gantry torsion box the rods go through the gantry sides and also through the X-Axis bearing adjustment box.

Jay "dighsx" added bed rail angle iron to the sides of his and also some straping at the bottom of the X-Axis bearing adjustment block. And he also added a spring loaded leadscrew tensioner. His website www.cncjay.com

3.) bolt the machine down, like all other machines they should be very stable this will help with the jerking of the machine when motors shift travel directions.

Have you added, or thought about the 8 TPI ACME Leadscrews?

Seems like I saw you or someone posting about it in one of the threads. I have read so much I cant remember where it all is. Sent you an email the other day.

Thanks
Glenn

Yes Rick used them on his machine 1/2-8 two start which gave him 4 turns per inch, the other day he was just testing the machine to see what it would jog at and got over 300ipm jogs. He also made his own anti-backlash based from mine.

One thing you can do before painting the machine is after glueing all parts together as required, use a mixture of half wood glue and half water then brush all parts with a foam brush and solution, this makes a very good base coat and when you paint it the paint sticks good and also does not soak into the cut end pieces, if you have tried to spray paint the ends before you will notice it soaks up alot of paint, the wood glue mixture seals the MDF very well.

Well I thought I might share some things. In another thread someone wanted more details or explanation of how the carpet tape is used in cutting parts. I like it because you don't have to worry about hitting screw heads but just remember to be liberal about it; you don't have to go crazy with the tape though. Before running the part, try wiggling it and moving it, if it moves at all DO not run the part, I've made that mistake. Take it out, put more tape or add a screw in opposite corners. Some materials it holds well, some not. HDPE seems to hold fairly well, as does solid woods, mdf and natural plywood.



Start off applying it.



Lay it down where you want it, I created a jig fixture by milling out two channels and using aluminum to create a removable fence. It works extremely well for parts you need to flip over and mill the other side. I had trouble with it in the past, but recently got it dead on; I just now design parts with the fence in it so that they all cut from the same home position in the program.



You don't always have to, but I do most of the time anyways removing the alum just in case I do through cutting where I may hit it.



Parts cut, everything held in place nicely. This is the bottom plate for joes new dc design and some other stuff I wanted to cut.



Take the parts out, a little cleanup sometimes, mostly just static and you can vaccum them up and they are good to go.

Also I had a problem with so much chips and dust getting on the bearings and rails so I was at home depot actually getting the plastic carpet runner material for the new dc housing and I saw these when they gave me the idea. They are just cheap vinyl toe kicks/base that are used in commercial rooms and sometimes cheap housing/apts. I think they are $3 for 4'. Screwed them in and they are working REALLY well. No chips on the rails now. If anyone does this remember to predrill every screw.

Looks good Brian!

The jig is a pretty slick idea!
I can't believe how well the tape holds things in place. I'll have to try that some time!

Order that ATC yet?

Sparky,

Ordered it the other day. Can't wait, so tired of having in consistent vcarving depths and having to reset everything all the time. Tape is good, just be careful, and test it with your own strength always before cutting. Cut anything lately?

It'll be nice, can't wait to see it in action!

No, I've just about finished the drawings for a gear driven dust collector attachment. I've got the gears and shaft. Will try to cut the parts this week.
It's designed it to work with the ATC and as drawn right now with a modification of Joe's original brush type DC collector. The idea is to get the DC raised so it will not interfere when replacing tools in the tool rack. (Which I still have to build also).
I've got to get back to my power supply / control cabinet so I can replace the Xylotex stuff and have the extra 269oz motor to try on the DC. Also will have to order another Gecko G203V to drive it.
Endless hours of fun!!!

Sounds interesting, I would like to see it when it's done.. still my biggest goal is to eliminate the vibration, wish there was some other way to show you guys so that you could determine in your best view how I could fix it.

bp092 - do you have a thread where you have documented you vibration.... been working on my vibrations and so far I have them figured out, might be able to use my knowledge to point you in the right direction.
