New build help needed

[arg123]

Thank you Kingcreaky

I was really lucky to ran into this forum just before I was about to start ordering parts. I can't judge Joe's cnc as I don't have the knowledge to do so but I will trust you all on that.

Yes the idea is for a machine accepting a full sheet of ply (2.5 χ 1.22 ) so the cutting area should be slightly larger for clamps etc.
Can anyone tell me the size of the base so I will not come short in the y(gantry) axis?

As per suggestions in other threads 80 x 80 x 5 steel tubing is a good option. Adjustability on the top rails and epoxy leveling is the initial plan.If the rack and pinion is the preferred way for the long axis, will the racks be bolted on the side of the top rails? Any extra consideration for the top rails then?

Help please

There are thankfully a number of suppliers on Greece that have rails and other parts but prices may be a bit high. With that in mind be prepared to spend 2000 euro plus if you want anything worth having.
Is your aim to have a working machine or to learn how to make one? I would imagine that you may be able to find good used machines around if you just want to get cutting.

Cutting wood and maybe aluminium is very different to cutting steel so wood machines may not be efficient at cutting steel, while steel machines will be too slow for wood and alu.


Before buying anything design it. Get familiar with CAD you will need it later. There are powerful free packages like onshape or fusion360 that will allow you to theoretically build your machine. Most of the standard parts are available in CAD format so it is pretty quick to model things.

Let us know how you get on and show us your progress

Thank you George,

I usually buy electronics from ebay and if I need aluminum from Misumi Europe.
My aim is definitely to learn how to make one. I set up a budget around 3500 - 4000 euros.
I was using sketchup before but now I am going to get a grip with fusion 360 for my 3d printing parts.

I will try to design the base looking at others build threads hoping that I will find the answer to my question about the cutting area(width) somewhere in the forum. Then maybe I will get some helpful comments.

If you add about 300mm to the length and about200mm to the width you won't be far wrong. When you draw it in cad you can check as it depends on what spacing's you use for your bearing blocks. Good luck with the build.

Then maybe I will get some helpful comments

And you haven't had some already
