Follow these steps to upgrade the firmware for your Prusa printer for a Slice Engineering RTD Pt1000. This will apply when you plug your RTD PT1000 into a thermistor port with no amplifier board
Part 1: Download Prusa Firmware
1. Download Arduino IDE - Arduino.cc
1. Go to Prusa Firmware
4. Locate and extract the file
6. Open the "variants" folder at the top and select your printer
7. Copy the file and paste it back into the "Firmware" folder
9. Scroll down and find the "firmware.ino" file, marked with Arduino Logo, double click the file to open the Arduino IDE previously downloaded.
-This will tell the Arduino IDE where to find the pin configuration for a Prusa printer
11. Click "Ok"
12. Navigate next to Tools > Board > Boards Manager and search "Prusa"
14. Compile the firmware by selecting the Checkmark (√) icon on the top left to ensure everything is reading correctly
This may take a couple of minutes, you will see a “Done Compiling” note at the bottom of the screen once complete.
1. Navigate to the drop-down arrow on the right of the screen and select the configuration_prusa.h file previously saved
3. Scroll down to "#define TEMP_SENSOR_0" value and change it from 5 to 1047
4. Optional: You can raise the temperature now to the max that your printer is able to reach
Scroll up to EXTRUDER SETTINGS
Under //Mintempts
Change #define HEATER_0_MINTEMP to 5 for the extruder
Change #define HEATER_0_MAXTEMP to 450
The RTD is rated to 500C, so use your personal preference here, we use 450
Scroll to //LANG - Multi-language support
Edit the lines to remove the “//” in front of
“#define LANG MODE 0 // primary language only”
Add “//” to #define LANG_MODE 1 // sec.language support
Go to Tools and chose the Port that your Prusa is plugged into on your computer
Make sure your Prusa is on at this point
Click Upload - arrow icon on top left
This will prompt everything to compile again, and then will begin to upload
Your Prusa screen will soon say “Upgrading firmware, do not disconnect”
After a few minutes, this upgrade should process without issue
