Hello! I'm thinking about building a 3000mm drawbot/plotter based on ACRO. How feasible do you think it is to join head to head 2 x 1500 V-Slot linear rails? Thanks
Checkout Quad Tee Nut - MAKERLINK (10 Pack) as an option to join beams Note that longer axis may suffer some more deflection: How to calculate V-Slot® deflection - but you can counteract that by extending the Y axis, and adding supports to the Y axis beams.
