AmBot CoreXY Large Format 3D Printer with triple Z Auto Leveling

Just a quick note since this got lost further down in the edits: The bill of materials, build guide, and electrical diagram are just copies of the originals from the D-Bot CoreXY. The wiring is SIMILAR, but more complex on this printer. And the assembly is completely different except for the outside frame. You will need to download the SketchUp model from the files here, and export the printed parts as STL to build this printer. Eventually I will put each parts STL in the files, I just have not had time yet. If you have any questions that are not already answered in the edits below, please feel free to post them in the comments here. ----------------------------------------------------------------------------------------------------------------- EDIT: 10/13/2023 Uploaded new firmware with correct build volume and Unified Bed Leveling added instead of just plain 3 point. I didn't realize that UBL also has a 3 point option as well so you can do the 3 point to get the bed level based on the three points, then run the full UBL mesh. Don't forget to save the mesh to a slot on EEPROM so you don't have to do it again after shutdown! EDIT: 8/27/2023 Uploaded the finished firmware for my printer. Included both the *.BIN file for those who don't want to change anything, as well as a RAR of the whole firmware directory so you can open it in Visual Studio Code and change settings. Everything seems to be working great at the moment. The only thing left for me to change is just the axis max travel distances as they are slightly too big for my printer right now, but that's not a big issue unless I try to print something that's too large. EDIT: 8/2/2023 Decided to abandon sensorless homing. It works fine, but is not accurate enough when restarting a failed print where it left off. If you want to use it feel free, but I decided to go back to optical switches. That's what will be set in firmware when I upload it shortly. My sensitivity settings were go
