    Re: 40mm finnish birch plywood CNC-router

    456802

    Next step would be to remove all the plywood :-) The triangle of the gantry side, that is hanging in free air, won't do you any good, so you can take it off, if you want to.

    Re: 900x600 Prosjekt

    Der har du mye bra. Men jeg syns dobbelt sett med HGR 20 på den lange aksen er skikkelig overkill. 20 er også plenty stort til de andre aksene.
