From 64097cb0d0e0a1e2a73f6846b48bae9b509204f1 Mon Sep 17 00:00:00 2001 From: Steven Snyder Date: Thu, 14 Jan 2021 08:01:58 -0800 Subject: [PATCH] config: Updates to TAZ6 single extruder config (#3750) The Lulzbot TAZ6 single extruder configuration had an XY position for z homing that did not match the factory firmware, and was off center enough to cause the extruder to crash into the home button trim sometimes when homing. This commit changes the printer config so that the XY position for Z homing matches the original Marlin firmware for this printer. The Lulzbot TAZ6 single extruder configuration had an bed_tilt points that did not match the factory firmware, and were off enough that the nozzle (used for probing on this printer) could slip off the edge of the probe point or miss it entirely. This commit changes the printer config so that the coordinates for bed_tilt calibration match the original Marlin firmware for this printer. For the Lulzbot TAZ6 single extruder config, use 'gear_ratio' and 'rotation_distance' to configure the extruder. The rotation distance is based on effective circumference of the hobbed bolt based on the original Marlin firmware for the TAZ6 single-extruder, and the gear ratio was determined by simply counting the number of teeth on the pinion and spur gears.
