Bob, sounds simple except the whole relay thing and controlling from Mach3 for the fancier version. I would definitely like a drawing for that if you don't mind.

Has anyone expanded this design to a 4x8 foot cutting area? Is it possible without too much change to the design?

Thanks,

Eric

Guys,

Just purchased Joe's plans and for those of you on the fence, go for it. They are very well written making it easy for anyone to understand. A lot of thought went into them and it shows.

Thanks Joe!!

His 4x4 is definitely going to be my next machine in a few years, heh

Yes, there is already Mods in the works to make one axis a belt drive or rack and pinion drive.

I am building a 4X8 rack and pinion. It will be done in the next couple of weeks or whenever Joe's kit shows up!!! :stickpoke

In a few years he might have a bigger and better machine.

Sorry been out a couple of days...I will draw something and put it up..

I have been following this design for some time and building one is definitely in my future. I would want to have a 4 x 8 cutting surface though and some of these previous threads hint that one is in the works. That's good news.

Maybe this has been discussed before, but I was thinking that instead of getting rid of the leadscrews on the long axis I would keep them and make them non rotational and spin the leadnut instead. Is this practical or has anyone ever tried it? It would get rid of lead screw whip on long rods.

Has been discussed several time, but now with the new 8 start One turn per inch leadscrews it is not needed, and only one leadscrew will be replaced with a belt drive or rack and pinion.

Bob finished his build for not, and add more bells and whistles maybe later on.

No problem. That's a good looking machine! I would have gone with a 4x4 if I had more money, heh

[joecnc2006]

Here's one completed, all parts cut by hand using templates.

[bkboggy]

Wow, by hand? Nice looking machine. What is that yellow hose/cable for?

[bp092]

Its used instead of a cable carrier, a conduit which is a cheaper but still functional alternative.

[bkboggy]

HMMMMMMMMM, that is an excellent idea!

Not sure about that comment

Joe,

I read somewhere that some of the guys on your new machine are having trouble with the abl nuts. I was told there seems to be a backlash issue with them. Any new news on this problem? Is the machine binding up or is it something else? Possible buyer here wants to know.

[bp092]

That I'm aware of there has only been one instance of it and that member is in the works resolving it with dumpstercnc now. There was some play in the ABL nut and he was trying to narrow down if it was the leadscrew or the ABL, but Tim as usual is providing great support for his products. It's an isolated incident really, don't let it put a crimp or doubts on purchasing the plans or a kit...
