Inconsistent Gcode errors, not sure how to continue troubleshooting...
This post on github (https://github.com/bdring/Grbl_Esp32/issues/848) is exactly what I'm struggling with, but the recommendation is to update/change the firmware. I'm not sure how I can do that with the FoxAlien machine. gSender has a firmware flash option, but it does not have a profile for the FoxAlien 4040-xe, and "Generic CNC" didn't seem to change anything.

Show HN: I built a CNC-machine from scratch, using 40x 3D-printed parts
I understand you put thought and time into your approach and it was a hobby to learn more abotu the process (and thus you know about MPCNC but decided to make your own). I've also build similar systems and I've learned some timesaving tricks that have paid off in terms of hobbyist enjoyment.
I really like buying the majority of the parts from a place like OPenBuildsPartStore, rahter than assembling frames from channel manually. Time/cost/quality tradeoff is hard to beat here.
I strongly recommend switching to Grbl_Esp32 https://github.com/bdring/Grbl_Esp32 with external controllers (this board https://www.tindie.com/products/33366583/6-pack-universal-cn... with these plugins https://www.tindie.com/products/33366583/external-stepper-mo... and these controllers https://www.amazon.com/STEPPERONLINE-1-0-4-2A-20-50VDC-Micro...). That's what I ended up with because tuning current using the little pots is dumb, and you want a TON of current going to those huge motors. ESP32 + Grbl has a bunch of nice features that aren't in plain old Uno GRBL.
My system has high torque NEMA23 with no gears (same motor for all 3 axes), I can't see any situations where adding more torque to the X or Y axes using a smaller gearer stepper makes sense.

New electronic for K40 - Seamless integration - Lightburn compatible
I have developed a new electronic board for laser machines that is using the wonderful ESP32 GRBL firmware and so compatible with all GCODE software including of course Lightburn

Pen plotters: not just output devices
if you want to see how it's done in modern plotters/CNC, Bart Dring's [Grbl_ESP32](https://github.com/bdring/Grbl_Esp32) is fairly easy to follow with good docs. I have one of Bart's plotters, as I don't have space or money for an Axidraw with all my other old plotters around the place.
For actual optimization of input files, [vpype](https://github.com/abey79/vpype)'s the one most people use.
Going back to really old/simple plotters, there wasn't enough code space to do any optimization. For example, the (fairly terrible) Commodore 1520 roll paper plotter had 2KB of ROM for all the 6502-compatible code its micro-controller used. When I first looked into the [firmware](https://e4aws.silverdr.com/hacks/6500_1/), I was pretty shocked that it printed text by scanning a table of character data from the start every time. Then I realized that even storing pointers for each character would use up about ⅛ of total storage, and the mechanical plotter mechanism was always way behind anything the code could do. So small mattered more than efficient

Help
I believe the Tool Change command is supported by: gSender or cncjs.
-
Can I connect my laptop to my desktop CNC with a bluetooth usb dongle?
Get a raspberry pi, https://www.raspberrypi.org/, throw UGS https://winder.github.io/ugs_website/ or cnc.js https://cnc.js.org/ on it.
-
If I don't use Windows or Mac and only use Linux, will I run into a lot of compatibility issues?
I use https://cnc.js.org/ to send g-code to the machine, this uses web page interface to set up the machine.

CNCjs - For CNC, same as above but for my CNC router, though I would never trust my CNC to run when I'm not physically close by ha ha so this hasn't been exposed to my OpenZiti network.

how to control your laser engraver with a raspberry pi?
I think cncjs is what you're looking for: https://cnc.js.org/

Laser engraver continually alarming!
Can you try with a different gcode sender software (cncjs), to see if you can Reset (red button) and Unlock (orange button)?

ortur Laser Master Pro 2 SF not burning
6 - Alternative, Save the gcode and use a g-code sender (example: cncjs). Notice: a g-code sender needs to know where is the 0,0 position/the start position, so in LightBurn select the start position "Current Position" and select the appropriate Job Origin. Save the gcode. On cncjs, move the laser to the "Job Origin" and zero both X and Y (the icon after the + on the Work Position). Click the blue Upload G-Code button, select your file and press the Play button to start the job.
