Thought I share some progress and idea of a good donor table.
New Project here in Sweden which will be using an IKEA Liatorp table as body to modify. The frame is pretty ok but will need some modifications and a paint touch up. https://www.ikea.com/us/en/catalog/products/50087072/ Since they are quite common here in Sweden I picked up a used one for $35 to test.
Outer dimensions 930x930 mm and workarea will be approx 750x750.
Still not decide on which mech solution to use. First the idea was to “copy” the polar design from Sisuphus but now I’m more leaning for a simple CoreXY.
I have tested to use a 8mm rod and linear plastic bearings based on this design https://www.thingiverse.com/thing:2920584 on an 450x450mm area with SilentStepStic TMC2208 which where really silent. Not sure how well they will work on the larger area so I’m also considering to use the ZenXY as an alternative. Might end up with a mix in the end.
