Anycubic Kossel/Delta replacement head body (+ retractable bed sensor mount) by o462

Last crawled date: 3 years ago

DISCLAIMER: This is currently being worked on. Parts are subject to modifications, and may require manual modifications to fit on printer.
So, here is my version of the Anycubic Kossel head body (I have the Linear Plus version), designed to include a retractable bed sensor.
It uses mostly the parts that comes with the printer, and does not modify the assembly. The additional parts needed is a 3010 fan (like these that comes with the chinese E3D j-head clones), a standard microswitch with the lever removed, and a RC micro servo (using MG90s, but SG90 should be fine).
I strongly suggest to replace the M3x8 screws that fix the body over the effector with M3x12 (M3x15 may fit too).
Head fan has been replaced to make room for the sensor mecanism. For now, the hole for fixing the servo have to be hand drilled, or the servo glued to the body.
I'm currently working on finding the right solution for the retractation, suggestions are welcome.
*** UPDATE 10/10/2017
Removed the 3Dprinted slider, it was hard to assemble and unaccurate.
Added a version with BLTouch mount. Sensor is at 0mm, -25.5mm (relative to nozzle).
PLEASE NOTE: you must modify the original effector for this version, grinding/drilling about 6mm in the effector at opposite side of the radial fan.
Feel free to contact me for any other Z height, this one is what fits my printer, but you may have a slightly different head requiring Z height adjustment.
