flsun kossel sd card contents and pre configured marlin 1.19 and 2.0 for skr v1.3

thingiverse

I'm rewriting the text for you. The complete SD card contents with nothing removed includes a preconfigured version of Marlin firmware, which is essential since the firmware that comes on the board with the Kossel is junk. The included firmware is specifically designed for stock boards and SKR v1.3 boards, both of which have large print beds. One of the notable features of this firmware is the auto-calibration option, which can be accessed through the Prepare menu page. To use this feature, simply upload the firmware, run the auto-calibration process, and then save the config. The Kossel.ini file that comes with the SD card contents is my Cura profile, which has proven to be a reliable example for others who may be struggling with their own calibration issues. For those who are having trouble calibrating their Kossel, I recommend checking out this YouTube video: https://www.youtube.com/watch?v=vEmBDYcx30Y. It provides an excellent step-by-step guide on how to get the thing working properly. To summarize, here's a step-by-step guide on how I got my Kossel up and running: 1. Uploaded the firmware. 2. Reset the board to its default settings in the Control menu. 3. Adjusted the delta settings to ensure proper calibration. In my case, this involved running the auto-calibration process several times until it succeeded. However, if you're using a SKR v1.3 board, be aware that the 40mm distance between your limit switches and the very top of the printer may require adjustments to the config.h file. Thankfully, the auto-calibration process from the LCD menu can correct this issue automatically. For those who are using the Bigtreetech SKR v1.3 board with TMC2209 stepper drivers for X, Y, and Z axes, and a TMC2208 driver attached to E0, please note that you'll need to adjust the motor settings in config.h to match your specific setup. The main firmware bin file is also included in the SD card contents and can be copied over if you're using the same stepper drivers. However, keep in mind that this may not work for everyone. One final note on calibration: I had trouble getting my Kossel calibrated due to a discrepancy between the steps per mm setting (80, 80, 80) and the actual scale used by the printer. To resolve this issue, I adjusted the scale settings in my slicer software, which resulted in perfect prints every time. If anyone else figures out how to correct this issue, please do share your findings with the community!
