This is why people make such a big deal about Klipper. Everything is in a plain text printer.cfg file. Want to change something? Just change the cfg file in the web UI (mainsail or fluidd) and click "save and restart". All it does is stop and restart the klipper program running on the pi. No other programs or devices need to be restarted. It it usually ready to go again in about 8 seconds and if you screwed something up it tells you where the problem is. Sending the file to print via the webui spoils you as well.

If you have any unused raspberry pies or spare PCs laying around, check out a tutorial on installing the mainsailOS image.

I just built another printer out of spare parts and it is being run by a pi zero v1.3. Couldn't get any wifi dongles to work with it, so using a usb hub with ethernet adapter built in. I could spend $15 on a pi zero 2w, but meh. It prints fine, but the zero isn't powerful enough for a webcam or input shaping.

Did a quick search & the first tutorials to come up look outdated.
This one looks good, at least the first few minutes I watched.

I have heard of klipper, but i know nothing about it. kinda seems like it just plugs in via usb and sends gcode directly through to the controller... then you just send your slices to the pi instead?

i do have a pi zero w kicking around... but apparently according to klipper there isn't enough processing power there to do it (well anyways)... i may just try it anyway and see if it ends up being an issue.

i do have some actual real mini ITX computers i could maybe use one of those. something to look into i guess... maybe a project for next weekend if i don't end up busy anywhere else.

You may want to look into Octoprint. There's also a 3rd party fork for Android. I bought a number of LG G6 "retail demo" phones and flashed new firmware on them. For about 30$ per printer, it adds WiFi, a web interface, a touch screen and a webcam. Not sure if it will solve firmware issues, but if the printer works properly with G-CODE, you should be able to post-process your files to do whatever you need to.

I just picked up a Creality K1 that uses Klipper firmware. You can use a web interface like Fluidd or Mainsail to access the firmware configuration file. You basically open it up like a text document, make whatever change you want, save, and restart the printer. It can't get much easier to tweak things. A lot of folks will use a Sonic Pad or Big Tree Tech Pad to add Klipper to a machine currently running Marlin. The pad does the processing and tells the controller board how to move the printer. Plus you get a nice big screen for your printer. Win-win. :) Klipper gives you the ability to adjust pressure advance and input shaping with an accelerometer. There are also lots of other calibrations that can be done through macros. It certainly has made fine tuning my printer a much easier process.
