Chaos, Patrick, gcormier,
I don’t know much about GitHub or doing a PR. So I downloaded the source code
“BIGTREETECH-TouchScreenFirmware-1-Vx.x.26” and made modifications that should eliminate all sending of M221 codes, then compiled a TFT35 E3 V3_0 binary file.
NO M221 BIGTREE_TFT35_V3.0_E3.26.x.zip (106.9 KB)
From photos above I believe that’s the model you guys are using.
Please try it and see if it fixes your problems, I don’t have an E3 display to test it on.
Good luck
