Hi,

I've been thinking to build new machine, 800x600 workarea, fully supported SBR 20mm round linear rails, ballscrews, hy200 2220 0210 ax08 steppers, chinese controllers and grbl with arduino/mega. Mainly use parts from my previous machine.

Now i'm obsessed with building machine frame and possibly gantry from GRP. I have plenty. I think im going with 800g vowen rowing and chopstrand mats with polyester resin.

I havent seen any of these type machines build? Is there anything that makes that kind of table/frame poor? I will be using mdf as sacrifial / wacuum table top.

Heres pic of my current setup and quick sketch of machine I've been thinking about to build just to clarify dimensions. Not sure yet if im going to single y axis stepper or using dual.

I mainly work with <12 mm birchplywood & mdf. I'm going for AMB FME 1050 digitally controller router as tool holder..
