u/Truesmas

Just got done assembling and flashing my bmcu. However, when I try to do a test print it over feeds into the extruder, loops purge and loading, then ultimately throws an error.

I've been trying to assemble this BMCU since last night but it's only spinning the first gear beside the motor. No possible orientation works.

I have a 2022 Rav 4 with about 55k miles (M20A-FKS engine), I've been having rough starts or stalling after starting when the engine is warm, worse when the AC is on. I did some research and found that it could be inter alia, a leaking injector I pulled the spark plugs and used a borescope to check inside the combustion chamber, this engine has 8 injectors (4x port & 4x direct) would you say the injectors are leaking? And what do you think of the condition of the pistons?
