FYSETC Cheetah CR10 ender3 ender2 FIRMWARE

Human: Currently working on the new FYSETC Cheetah board, a nice board with the same form factor as Creality ones. For features of the board, you can check out their page and the GitHub page: https://wiki.fysetc.com/Cheetah_Board/ I'm not affiliated with Fysetc and am not responsible for any damage to the board or other parts involved. However, I liked the board and the all-in-one TMC drivers, so I've decided to make something about it. UPDATES: - CR10 with double motor (currently testing myself): Y-motor heat issues - Ender3 (testing with a friend): Motor heat issues still searching how to calibrate them - Ender2: Still not tested, just firmware compiled; need another board Firmware modification from the original file: - 1st important change: Enabled store EEPROM settings; it's better to change any value, especially for TMC current - 2nd added the right settings for the bed pin and hotend, also enabled autotune, disabled from the original firmware - 3rd set all the values I think are correct for TMC drivers (values inserted in brackets); I still have a bit of problem with my Y motor heating too much, and I've read that it's a current bug on TMC, so probably we need to reduce the current; I suggest monitoring them or updating the firmware if I find the right fix - 4th set all the dimensions of the print volume for printers: Ender3, CR10, and Ender2 - 5th added TMC debug and monitor, in order to control the printer from the terminal MISSING: - A firmware for CR10s and others with the filament sensor; if you can give me info, I can enable it and let's test DISABLED: - RGB LED light; not planning to see if it works or not DEFAULT MOTOR SETTINGS: - Stealthchop enabled, makes it really silent; you can disable it also from the printer LCD menu INSTALLATION: - Can be found here: https://wiki.fysetc.com/Cheetah_Board/ - You already have the hex file, so jump to the flashing part: Step 1: Connect the board (better if only the board, there is no 5V jumper, so in my opinion this is a big flaw); in case you have all connected, flash with the main PSU on, in my case 12V CR10 Step 2: Open FlyMcu.exe Step 3: Set: - The right COM port - BPS: 460800 - Also set Reset@DTR low (less than 3V), ISP @RTS High Step 4: Press Start ISP and wait a few minutes; you're good to go. WARNING: - Current settings: the real value has to be multiplied by 1.424 because we are talking about RMS current, so any value in the firmware will be lower (exactly divided by 1.414) - Values for motors: - 0.725A motors (used on Ender's X, Y, Z) current value: 500 - 1A motors (Ender's E motor, CR10's X, Y, Z, E motors): 700 or 650 - Dual motor in parallel 1+1A (CR10 dual motors Z axis): 1300 or 1400 - In case of overheating, plan to reduce them by 50 and so on; you can also try to disable stealthchop and enable spreadcycle, which will be more noisy but should reduce heating At the moment, I'm experiencing problems only with the Y motor on the same three motors (X, Y, E); if anybody has any solution, I'm all ears. The TMC developers say it's a matter of tests for now, and what I know is that using 1.5-1.7A motors would work better on the TMC2209 (I'll test that too) If you find my work useful, you can buy me a coffee or two: https://www.paypal.me/raffoslab I drink much of it
