Polar Zen-Sandtable

WORK IN PROGRESS

I like the ZenXY, but I want a round table. So I designed a polar version of it.

first try: https://www.youtube.com/watch?v=vN0LI9nvCRA

required parts:

1x aluprofile 2020 (length at your choice, I use 400mm)
3x Wheel for 2020 profile
1x bearing 6011
1x slip ring 6 wires (I´m using a 8 wire version)
2x NEMA 17
1x GT2 closed belt 500mm
1x GT2 belt - length depends on length of your profile
2x GT2 pulley 16t
4x GT2 idler 16t
1x electronics of your choise - currently I´m using RAMPS 1.4
2x TMC2208 (for silent operation)
1x power supply
1x mechanical endstop
1x neodym magnet 12mm
1x round glass
and wires, bolts...

milled parts:

(I split the circle to 6 parts to save material.)

printed parts (I used PLA):
1x slider2020.stl
1x base.stl
1x Rad.stl
1x Motorhalterung.stl
2x Endstophalterung.stl (1x mirror inverted)
1x Arduino Mega Mount (e.g. Thing: 53857)
3x Cable Management (e.g. Thing: 1561292)

1x TPU-Entkopplung.stl (use TPU)
1x TPU-Entkopplung-Motor.stl (use TPU)

next Steps:

1. cable management!!! DONE
2. firmware adaptions for polar CNC DONE => works but not handy. Trying R360 firmware
3. building and sanding the frame DONE
   (4. Add LED stripes)
   (5. Smartphone control)

FIRMWARE:
I´m using kartesian Marlin. Y is used as polar axis. Movement of 360mm is a rotation of 360°.
=> Using the Polar Pre-Processor from bartdring. Thank you for your work!
