Note, I will try to keep the last 3 firmware's in rotation but if you need a special configuration for your printer please let me know what you need and I will be happy to tweak if for your specific setup.
If the TFT firmware stops updating at 119 images, create a blank config file named reset and place it on the SD card alone, flash with it to reset, then flash TFT again.
**If your Sidewinder has been updated in the past, proceed to Step 2:**
**Part 1:** First, you will have to open the front bottom of the printer by unscrewing the two screws in front of and two behind the rubber feet. The front half of the bottom cover will now open enough for you to reach in and unplug the white 4 (four pin) ribbon cable to the TFT screen. There will probably be some glue holding it in for shipping, carefully scrape some away until the connector comes off.
**Part 2.** Launch [PrusaSlicer] (https://www.prusa3d.com/prusaslicer/) Go to Configuration and select *Flash Printer firmware.*
Browse to the firmware.hex file you downloaded and hit OK, *IMPORTANT* i have been able to flash my firmware by clicking the flash button immediately following the communication beep after connecting to USB so listen for it and be ready!
now plug in the USB to the printer and select your COM port. now if the Serial port field is empty click Rescan. If the Rescan does not produce your printer COM port, you will need to install the USB drivers from the same link, simply select Download drivers & Apps package for your OS. Now select Flash! and follow prompts for it to finish. Once you see, *Flash Successful*, either press the reset button on the printer or simply unplug the USB and power it on from the switch on the rear.
**PART 3** TFT firmware and Icons update:**
Copy the files in the MKS directory to the root of your SD card, I use a 32GB, so smaller should work just fine and the 16GB myth is squashed. HOWEVER, I do recommend a cheap 1 or 2 Gb set aside just for firmware flashing as my memory card was corrupted and about 30 gcode files were lost...
ok, now restart the printer and you will see updating, once complete reset the printer from the reset button next to the TFT and power it on from main power.
TIPS:
1. The first thing I recommend doing after the firmware is going to the EEPROM and resetting it to factory.
*2. Preheat the bed using the preheats for Wood which is 170/60 and good for bed leveling. now for the most important thing, perform a 4 corners bed leveling with a sheet of paper or feeler gauge until you can slide a sheet of paper under it but still feel the nozzle touching it, repeat 2,3 or until the feel is the same all around, this is the foundation and will make the next mesh leveling step that much easier and more accurate.*
3. Once you are happy with your corner leveling, perform a Mesh Bed Level, you are looking for the same feel as the four corner level. You will know you corner leveled correctly when your mesh level is within 10-15 mm. Once complete you will be prompted to save to EEPROM, do so. You are now ready to print!
**If you get a "Printer Not Attached" message, set the baud rate to 250000 under Menu/Settings/Connection/Baud rate**
To enable remaining time when using Cura and a few other slicers, make sure to enable Progress in post processing scripts, see image.
