I have a Geeetech A20T printer and would like to use it with Klipper,
I installed the Mainsail OS on my Raspberry PI and created and downloaded the firmware.
I’m currently getting a connection, but I probably haven’t configured some things correctly. I used the standard configuration file (generic-gt2560.cfg), but it is not 100% correct for this printer.
I’m currently getting the error message:
MCU ‘mcu’ shutdown: ADC out of range
This generally occurs when a heater temperature exceeds
its configured min_temp or max_temp.
There may already be a suitable configuration for my printer in this forum.
I found something here that probably already has a solution.
Well I can give you all of my config files for my Geeetech A20T but you will have to change the connection becouse I have it connected via uart on the board. I had to flash it with other bootloader so that I can use it for flashing it with klipper.
These are my config files (remove if any imports like PIS and KAMP and other if you dont wanna use it): config.zip (13.9 KB)
You will also have to remove the power things I am using relays to turn the main power suply of the printer off an on. Another thing I am using 1 to 1 extruder not the diamond one that came with the printer becouse it was horrible and I dont even want to print multi color anymore. So you will have to change how much it retract in the extruder_change.cfg (change the G1 commands)
I haven’t had any experience with selecting the colors yet, I’ve currently adjusted the config so that everything works for me (Pressure Advance - Simply Explained, and new configurations for the three extruders).
I haven’t tested the mix variant or the colored printing yet, I use PursaSicer 2.7.0 for slicing.
Well for me it propably cant be a connection issue becouse it just doesn’t startup sometimes but if I restart it few times the bltouch clicks 3 times and it works but sometimes it just gets stuck down and doesnt work I have no idea why.
