   Will the BTT EXP-MOT V1.0 Module driver expansion module work with the Octopus Pro board? I know it would require longer EXP ribbon cables, but is there anything else preventing it from working?

   My SKR2 can be powered from USB but not from 24V. When I turn on the 24V power supply, it repeats On and Off. I attach the video of the condition. Please let me know what is the problem. SKR2-24v.mp4

   BTT Octopus 1.1 PT100 J47 input...

   Hi everybody! I wanted to use the PT100 input J47 (PF8) of my octopus 1.1 board. So I ordered and installed the INA826 chip required. I did the right config in Klipper to get the reading. Now my reading is -227 degC like if there was no sensor. My config is: [temperature_sensor ambient] sensor_type: PT100 INA826 sensor_pin: PF8 What's wrong? Is there somebody who did this move? Thanks. Francis
