Hi Joe,

Coming together nicely now. Is there any reason on the gantry for putting the X axis bearings out the back and the spindle hanging out the front? Normally you would put a bearing near the spindle axis to give more support. Do you need to cut right over the edge of the machine?

Not saying it won't work as drawn because it will, just that it could be a little better if there was no reason for the bearings positioning as drawn.

Looks a very nice setup..
I am interested in a similar style'll of machine capable after taking an 8*4 sheet material....would be gratefully for some advice on material suppliers ,like aluminium extrusion and bearing guides ect.

Hello,

I'm very exiting your cnc design. Maybe you have video how cnc works? maybe can get drawings from you?

Hello, whilst I'm not at all opposed to sharing, in my experience the design process is essential if you want to understand what you are building and why. I would encourage you to read a lot on this site and others then get drawing!

I had decided to go with slaved motors but I really want to use a CSMIO/IP-M Motion Controller and they don't like slaved motors. Early on I had toyed with a belt drive and after reading posts on biketrialdave's build log I'm heading back that way I think. The belt will need to be made as it is over the size limit for standard belts but the cost of a custom one does not seem extortionate! The basic idea is as the image above... which would not require much modification from the existing setup. As usual, any comments are gratefully received!
