TAZ Plotter (for TAZ6)

thingiverse

Simple plotter head designed for TAZ6 printers, with potential compatibility for other versions. The "v1" design draws inspiration from Tech2C's over-engineered plotter design for the Hypercube printer. I re-used his pen holding cart and created a new holder that fits snugly in the TAZ V-groove, reverse-engineering existing Lulzbot STL files to determine exact dimensions. As seen in the photo featuring owls, the pen was initially held high up, resulting in acceptable but slightly inaccurate performance (-0.5mm). In response, "v2" aimed to address these issues by repositioning the holder directly onto the X carriage. However, this design requires unscrewing four screws from the V-groove before installation. For users who prioritize convenience over accuracy, both "v1" and "v2" are available for download. STEP files have been provided, allowing you to modify or CNC cut the design as needed. Additional notes: * When upgrading your TAZ extruder, disconnect it by unscrewing it rather than cutting power, as this can lead to erratic movement. * The rubber band's tension can be adjusted and fine-tuned using screws for optimal performance with a given pen. * Many bullet-point pens exhibit significant tip slop within their housings. This issue is easily resolved by wrapping the drawing element in tape and reinserting it without spring pressure. * For those interested, see v2 in action on YouTube at https://www.youtube.com/watch?v=C4Ra8TNE9k4 (apologies for poor quality). * My design was printed using ABS, but I've modified the hole dimensions to default to PLA. If printing with ABS, you may need to drill M3 holes. * Jscut.org is an excellent tool for generating gcode from SVG files, although minor modifications are required to make it work with Marlin firmware.
