Marlin
Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.

What I’ve tried/double checked: * Bed level manually * Used the relatively new Marlin feature to level bed corners. Essentially it moves the probe to each corner to measure the distance until the probe triggers, if the distance is larger than the set threshold (using default 0.1 mm in my case) it sets the probe at the appropriate distance and waits for you to manually adjust that corner to trigger the probe, it continues until all corners are within tolerance. * Released in Marlin 2.0.8](https://github.com/MarlinFirmware/Marlin/releases/tag/2.0.8) with PR-20241 Level corners with probe option * Verified using Bed Level Visualizer plug-in in octoprint (reports perfectly level with 0 deviation) * It reports as perfectly level with 0 deviation which makes me a bit suspicious but I have used the plug-in with the ABL probe before and received the more typical not level readings, the only changes I know of that would impact are switching from the stock ender 3 pro magnetic bed to a glass bed and using the above mentioned Marlin feature to level instead of just manually leveling with paper. * Checked probe accuracy - Deviation 0.001750 * Used M48 command to execute test, my understanding is that this deviation is well within an acceptable range so the probe should not be causing the issues * Measured the extruded filament to confirm nozzle is not under extruding which could present as the nozzle being too far. * I’m not sure if this is actually something that matters nor if my methodology was correct but with a 0.4 nozzle I extruded some filament and measured multiple points with calipers and results were around 0.5. I don’t understand why the measurement is larger than the nozzle size but in either case it doesn’t seem to be under extruding at least so shouldn’t be the culprit of the gaps. * Save probe offsets to EEPROM rather than just relying on the offsets I set in firmware.
