Created by Dendrowen (dendrowen on Discord). The Macro is based on a +# version, and Nozzle Scrubber is made by Hernsl (hernsl#8860 on Discord). The device is +# designed around a Voron V2.4 300mm, but should work for 250mm and 350mm too. This +# version only supports the assembly on the rear-left of the bed. If you decide to change +# that, please consider contributing to the project by creating a pull request with the +# needed changes. + +# IMPORTANT: The rear-left part of your bed becomes unusable by this mod because the +# toolhead needs to lower down to 0. Be sure not to use the left-rear 130x35mm. + +# The goals of this combination of devices is to dispose of purged filament during a +# multicolored print without the need of a purge block and without the flurries of +# filament poops consuming your entire 3D printer room. The Blobifier achieves that by +# purging onto a retractable tray which causes the filament to turn into a tiny blob +# rather then a large spiral. This keeps the waste relativly small. The bucket should be +# able to account for up to 200 filament swaps (for the 300mm V2). + +# The Blobifier uses some room at the back-left side of your printer, depending on your +# printer limits and positions. (usually max_pos.y - toolhead_y and brush_start + +# brush_width + toolhead_x). If you do place objects within this region, Blobifier will +# skip purging automatically. It does this by extending the EXCLUDE_OBJECT_* macro's, so +# make sure you have exclude objects enabled in your slicer. + +# If your using Blobifier in conjunction with the filament cutter on the stealthburner +# toolhead, you can place the pin at max_pos.y - 7 (e.g., max pos y is 307, place it at +# 300). The pin will then poke through the cavity in your toolhead. (Be careful with +# manually moving the toolhead. I have broken many filament cutter pins) + +# It is advised to use the start_gcode from Happy Hare. Then you will be able to fully +# and efficiently use this mod.

[klipper experts will know that it switches the chip mode automatically to stealthchop and then back for +# Stallguard2 support, however the automatic switching back to spreadcycle at the end homing move seems to provoke +# the error condition and setting 'shealthchop_threshold' appropriately avoids this condition.
