Looks really nice!
I'm not interested, cause I already have my own CNC. But I am curious, what is the z-travel?

so a 2' x 6' machine with motors electronics and a mach 3 license would run me $4590 USD before ship?

@ Twizz;
The stock Z is 6" without the spoilboard. The rails can be shimmed up off the table surface an inch with T-Slot blocks to give 7" of pre-spoilboard travel without needing to install a longer leadscrew. If more hieght is still needed a longer leadscrew is available. In both cases of shimming the rails longer mounting brackets would need to be made by us or you.
@Madman;
yes the math is correct however the 6' rail extensions would give you a full 4'x8' turn-key machine for that price. The base unit still comes with the 4x2 rail system you would just be adding the extensions.
Moving to the t-slot material has made the machine so much easier to fabricate and build, allowed better scale-ability, and increased the overall strength of the gantry and rails.
Its a good machine and will more than hold its own against much more expensive units. I am happy with how they have progressed in such a short time. Thanks for the questions guys.

Odin, that is a very nice machine. The price is good!

What is the linear motion system?

been wondering about that too...looks like some sort of plastic sliding directly on the aluminum extrusions.

Looks like rack and pinion to me

there are multiple uhmw linear motion sliding types available. Looks like odin made his own perhaps?
I just wonder with all that dust, is it sealed enough and how long till you have to replace it as Im sure you will eventually.
I have looked at many of these as a possible low cost alternative to thk style rail.

I meant linear bearing system sorry.

yes it is a UHMW linear slide bearing system designed with close tolerance that actually shovels dust off of the rails in front of and behind with travel. As far as replacing; its a matter of ordering new slide blocks and attaching them with the on hand hardware if needed. There are also wear compensation adjustment points on all axis to prolong the life of the bearing blocks.
Overall the machine is built to work, being inexpensive to purchase, simple to operate, and easy to maintain. I have strived to make this a clean and elegant machine that when set up and taken care of has very few items that should ever need to be replaced or repaired. That means less down time where you're throwing huge amounts of money toward a fix to get back up and running.
Honestly most folks probably won't look twice at this machine believing that it's not expensive enough or doesn't use one of the high dollar linear systems that must surely mean better quality. And that's ok, this machine isn't built for them.
But if you're a guy in a garage like I am or a small rented space then you know that every dollar you shell out for a tool that doesn't make life better means you spend that amount again chasing after a tool that will. We already work two or more jobs to support our shop projects and can't afford the added headaches. Allot of the time we wind up making our own tools and jigs beacause it's the only remaining option. That's who this machine is built for, and by
Thanks again for the comments and questions guys.

Right on!

odin, have you considered the addition of a drag blade type spindle and the control of what I learned as the theta angle for detailed die cutting of plastics?
This would obviously be a perfect add on to our industries if accuracy and repeatability is high.

yep its been done.
