Kossel Alt with optical autoprobe, m5 bolts

thingiverse

**UPDATE 1: Here is the wheel carriage conversion parts for this printer:** https://www.thingiverse.com/thing:2577466 All parts for the main frame is for M5x10mm bolts. Only the part "Kossel_Rav_Alt_top_frame_optional_support" and "Kossel_Feet" need optional m6 bolt to screw it to the vertical frame ends. To do this, you need to tap the central holes of the vertical frames. Effector is derived from here: https://www.thingiverse.com/thing:1134299 Original carriage was for one LM8UU. To make it more rigid, I made a taller one for one LM8LUU or two LM8UU. You will need three GT2 M3 idlers with tooth for the counter sides of the motors. I am also adding the latest marlin 1.1.5 configured for allen key probe, which I am still using. You need to do an auto calibration and change the relevant numbers in the firmware. You will need an 20x10x3mm sized earth magnet for allen key autoprobing. I placed all the electronics under the printer. So I added a fan holder for 6cm fans which is used for cooling the drivers. Also I have used a 220V silicone heater with a SSR as heated bed. I strongly advice you to like that. My endstops are mechanical without the module. So I designed a holder for them used as X, Y and Z endstops.

I was totally noob about deltas when I started to make this printer. Specially auto probe function was very time consuming for me. So if you have any question I can answer with pleasure. Hope you enjoy.
