ApolloKlack

For anyone not on discord this has been a concept made by SiFire, which was inspired by the klack ender by kevinakasam. I then redesigned some parts and improved some others, so no print support needed.

The wheel model is not yet tested, feel free to test and report. But would likely work
you need to reach about X 248~249mm, you might need to tweak your [stepper_x] in klipper (just make sure you can physically reach it)
Worse case, you would only need a tweaked dock piece, catcher and duct are good and won't need reprints.

Rail model works great, but you do need to reach at least X 252, if you can't you'll need to change the X tensioner that allows that (in the master repo page the "PRINTER MODS - by Squirrelf" has one that I made that will allow about 255~260mm move on X)

STEP file included

There are 4 version, to try and get Y probe offset to be 0

• wheels for top/groove mounted hotend, like V6 Dragon, Rapido, etc
• wheels for back mounted hotend, like stock and dragonfly BMS
• rails for top mounted hotend
• rails for back mounted hotend
  
  some hotend won't be perfectly aligned and will have a small Y offset
  
  X offset is only 29mm
• six magnets 6x3 (Amazon )
• two  M5x8 and two T-nuts (if you did the belt mod by kevinakasam, you likely have some spare ones)
• m3x20, likely work with m3x25 for the dock

omron switch D2F-5 ( digikey )

Also makes sure to match the magnets polarities

Aug 8, 2023

- entering beta phase
- I reuploaded it a few times after fixing some gcode
- added probe_calibrate info

rev2:
- better catcher

rev3:
- probe alternative, small improvements (allows installing the switch after the magnets, and has better bridging)
- tweak to config (30mm X move to the left after docking, instead of 20mm)

Aug 20, 2023

- M3 model of the catcher
- added another klipper macro for bed screw calibration aka SCREWS_TILT_CALCULATE

Aug 25, 2023

- New probe (rev3), cleaner print, better magnet holes (no bridging), no support needed
- Version for UHF,  duct/dock/catcher
- Version for Unitak3d X-axis rail kit
- fixed default orientation of M3 catcher
