Delta Kossel ZProbe Optical Endstop Flag

thingiverse

An optical endstop flag for the Nylon "Delta Kossel Fisheye Effector with Adjustable Balance Levelling Hammock" is commonly found on Aliexpress.\nWhile this design boasts "autolevel", there's no obvious way to attach either an optical or mechanical endstop switch, and no instructions are provided on how to do so.\nFortunately, rwubbels has shared his "Kossel effector autoleveling with optical switch" project on Thingiverse: http://www.thingiverse.com/thing:1191506\nA simple standoff allows an optical autolevel sensor to be attached, but while he used a bent piece of wire as the trigger, I preferred something more "flag-like" since the wire would initially trigger - then disengage if pushed past the effective sensor area.\nThis design is a straightforward remix of byteborg's old Prusa flag, tweaked until it fits snugly in the new effector. Attach to the mounting point on the effector using a 2mm self-tapping screw.\nPrint Settings\nPrinter: Micromake Kossel XL\nRafts: No\nSupports: No\nResolution: 0.2mm\nInfill: 20%\nNotes:\nThis is a small print, so exercise caution. Use a skirt to ensure printing starts cleanly.\nI used black PLA, which isn't ideal - as it's too reflective and will cause the optics to "bounce" back, failing to make a clean break (this is well-documented in relation to other flags).\nTo avoid this issue, you can paint the PLA with something non-reflective (black paint, or use black liquid electrical tape) - or opt for ABS.
