Drawing Robot - Arduino Uno + CNC Shield + GRBL

Warning: I'm getting more messages from builders of this robot saying that either the required software is not available or it doesn't work under Windows 11. I may eventually remove this "Thing" since I don't want people to invest time building a robot with no software support. Be warned, this robot is a lot of work and it may not be possible to operate it as newer versions of Inkscape, GRBL, UGS, and Arduino may present incompatibilities. If you think you have the software abilities to resolve conflicts, enjoy this project otherwise I suggest building a newer design where someone has updated the software. This design still presents useful documentation for the mechanical build of a drawing robot. The DrawBot is similar to the commercially available AxiDraw. It is powered by an Arduino Uno controller, uses a CNC Shield, and GRBL firmware. The approximate cost to build the DrawBot is $100. Recently some makers of the Drawing Robot have reported a hang up issue with the Drawing Robot Software. I didn't write any of this software. It is all open source or commercially available. I haven't seen the hang issue but I also see that some of you have moved to software other than the suggested combination. It is hard for me to troubleshoot all combinations of software. This Thing is dependent on GRBL, Inkscape, Java, and Universal G-Code Sender. I have seen cases where changes in the version of Inkscape conflicted with either Java or GRBL. That is why I have suggested a known working set of software. I posted this thing to give people a cool project but it is not a product. If you decide to try other software, you will have to do your own troubleshooting. I do acknowledge that even with the suggested software that you could run into a problem such as a hang on long plots (> 2 hours?). I've tested on plots as long as 90 minutes without issue but it is possible that a long plot could hang in a way I haven't seen. If someone finds the cause and fixes it, I will be grateful an
