help with my cnc build

[EddyCurrent]

OK I'll start the ball rolling with a quick reply.....I'll certainly not get into the debate about using MDF.........

The Y axis on the gantry needs moving to the back so the spindle is nearer the middle of the bearings, not hanging right out at the front. You'll also gain some more cutting space this way.
:D

This is the drawing I generally refer to; http://www.cncroutersource.com/do-it...NC-router.html

thanks njhussey

before i spend to much time doing my plan again, is this what you mean

[IanS1]

If you're happy to build the machine in MDF then why change the metalfusion design?
.
One thing that would improve it would be to use two motors/ballscrews on the X Axis and beef up the X Axis rail supports.
.
Have you seen his build log here? http://allthemods.com/project.php?id=386

That design obviously works, but having the spindle hanging off the front seems to go against the grain when you ideally want it in the middle of the bearings?

hi havent finished the drawings just making sure i was doing the right things you said, will update with more pictures soon

[IanS1]

Agree with you completely Neil. Building a machine from MDF also goes against the grain.

well atm i cant afford making it in steel, as im disabled money is spare so, i will have to make in mdf then upgrade to steel when i make some more money

or unless someone can make me one cheap lol

I didn,t think that MDF had a grain plywood has, so that might be better. Good luck with whatever you decide - all cnc routers are grat, so have fun and enjoy making and using it. G.

done a few more bits to my plans and just need to ask a couple of questions as to what way would it better to do my z axis, 1st or 2nd picture


this way i would upgrade the boxing on the z axis, just wanted to know what way would be better before i spent to much time on it

or this way


thanks for all your time
