I have a strange problem. I just installed a new board in my A20M and also installed TMC2208 V1.2 Stepper Drivers. I also flashed marlin 1.1.8 with bltouch and inverted the stepper direction. #define INVERT_X_DIR false #define INVERT_Y_DIR false//false #define INVERT_Z_DIR true//true // Enable this ...

Thanks

I have had my A20M for almost a month now and I have recently been wondering if there are any locations that need occasional lubrication. For instance, the Z screw may need oil or grease, but what type? Also, do the bearings or extruder and stepper motors need oiling to extend life. Excuse my ignora...

Thanks.

Does anyone know what size the hotbed leveling screws are on the a20m? I'm thinking of making leveling knobs with nylon locking nuts.
