I'm setting the marlin. I'm uploading. when i plug in extruder and bearing thermistors motors etc nothing works.... Mks gen l V2.1 tmc2209 . By the way, if I can learn about the sensorless event, I couldn't stop the motors with a switch :D

Hi Edward,

Your videos are awesome ! I followed your MKS_SGEN_L v2 Basics video and it worked just fine. I flashed the sdcard and everything was easy because your tuto are just amazingly well made !!

Now, I tries to replicate what you did in this video but it's not working and I don't know why... When I connect the printer via USB, I have a message that the USB is not recognized, but I can see the COM3 in platformio HOME when I connect my printer, but It does not appear in windows explorer.

When I try to upload, I have an error:
...
...
RAM: [==== ] 39.8% (used 13016 bytes from 32736 bytes)
Flash: [==== ] 35.3% (used 167892 bytes from 475136 bytes)
Configuring upload protocol...
AVAILABLE: blackmagic, cmsis-dap, jlink, mbed
CURRENT: upload_protocol = mbed
Looking for upload disk...Error: Please specify `upload_port` for environment or use global `--upload-port` option.

been 4 days I knock my head on the wall and ran out of options. I even looked your video frame by frame and copy every single info without succes :(

How do you do ?

What is your COM / upload_port configuration ? Please help !
