Hi, @Amazon62 According to your description, it may be caused by high compensation value, please according to the video tutorial on leveling to adjust the compensation value. Leveling tutorial: https://youtu.be/9u4H6cm_CX4 You can remove the limit switch used before, and the wiring of BL-touch is shown below.

From the picture belongs to the print midway plug, extrusion is not enough 1, check whether the normal rotation of the axial fan of the nozzle 2, printing in the extrusion motor is normal rotation 3, tighten the extrusion clamp screw, increase the extrusion pressure 4, check whether the extrusion clip is broken

hi, Daniel,from your image, maybe the problem is the leveling too high, so the filaments are not easy to stick on the platform. you can try to relevel it, just like this

" I renamed the "Marlin2.0.1 BLtouch V1.1.1 Non-adapter board firmware.hex" file to "firmware.bin", put it on the SD card, then powered up. However, the screen stays blank and it doesn't appear that the firmware was updated. Any ideas on what I'm doing wrong? " Yes, what you call a .hex file is already a .bin file and should not be renamed at all. Without bltouch you only use the Endstop firmware version. Either the bltouch comes with an adapter or not , so not much to choose from, either V1.1.1 or V1.4.1 is what you need then. Just put it in your SD card rootfolder , insert card in printer, power on printer and it should update automatically. greetings.
