CNC - 3D printer plotter

Many thanks to Mr. iamjorgensen for his fantastic ideas! I really appreciated them. Here's the link to the project: https://www.thingiverse.com/thing:2105510/files. I recently designed a brand new plotter for my state-of-the-art 3D printer, featuring an impressive working area of 32x42 square inches. Check out the project on Thingiverse: https://www.thingiverse.com/make:791080. It was incredibly inconvenient to remove the spindle from the CNC machine every time. I'm expecting a new laser cutter to arrive soon and join the team! The mount is specifically designed for the carriage I've been using. Have a look at it on Thingiverse: https://www.thingiverse.com/thing:4014799. Watch this video to see it in action: https://youtu.be/OuUloKDNayc. To generate g-codes, I rely on ArtCAM with a custom postprocessor. Here's the configuration file for my 3D printer-plotter: FORMAT = [N|@|N|1.0] FORMAT = [S|@|S|1.0] FORMAT = [F|#|F|1.1]; Tool moves in x,y and z FORMAT = [X|#|X|1.3] FORMAT = [Y|#|Y|1.3] FORMAT = [Z|#|Z|1.3]; Home tool positions FORMAT = [XH|@|X|1.3] FORMAT = [YH|@|Y|1.3] FORMAT = [ZH|@|Z|1.3] START = "G92" START = "G0 Z10" ; you can change it RAPID_RATE_MOVE = "G0[X][Y][Z]" FIRST_FEED_RATE_MOVE = "G1[X][Y][Z][F]" FEED_RATE_MOVE = "G1[X][Y][Z]" END = "G0 [ZH]" END = "G1 X0 Y0 Z0" END = "M84" The process is straightforward: 1. Reset the system 2. Move the pen to its starting position 3. Lower the Z-axis - pen/knife to workposition (I use 2-3mm below the paper for safe height) (3.1 step: you may need to reset here) 4. Start the G-code file The plotter features a 6mm shaft and LML6UU bearing, with removable pen and knife holders secured by turning and screwing. The system runs on standard Marlin 1.1.9 and Ramps 1.4, MEGA 128 hardware.
