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 main frame parts require M5x10mm bolts, except "Kossel_Rav_Alt_top_frame_optional_support" and "Kossel_Feet," which need optional M6 bolts to attach to vertical frame ends. To do this, tap the central holes of the vertical frames. The effector is based on https://www.thingiverse.com/thing:1134299. The original carriage was designed for one LM8UU; I've made it taller for one LM8LUU or two LM8UU to increase rigidity. You'll need three GT2 M3 idlers with teeth for the counter sides of the motors. I'm also including Marlin 1.1.5, configured for Allen key probe, which I still use. You'll need to do an auto calibration and update relevant numbers in the firmware. A 20x10x3mm earth magnet is required for Allen key autoprobing. All electronics are located under the printer, so I added a fan holder for 6cm fans used for cooling drivers. The heated bed uses a 220V silicone heater with an SSR; I strongly advise using this setup. Mechanical endstops without modules require a custom holder designed to work as X, Y, and Z endstops.

As a noob to deltas when I started building this printer, the auto probe function was particularly challenging for me. If you have any questions, I'd be happy to help. Enjoy!
