![]() If you get an error saying can't connect to board you will need to disconnect your printer from repetier host and then try again. The values entered here will not necessarily be the same as yours.ġ9. Replace the old values with the ones you just gained from the PID tune. Open the Arduino IDE again and find the PID settings in configuration.hġ8. After it has run through the 5 cycles that were set it will show the Kp, Ki, and Kd values in the dialogue box.ġ7. Enter the following into the terminal: M303 C5 S200ġ5. Make sure the COM port you have the printer plugged into is selected.ġ4. Once you have downloaded Repetier Host open it up and click printer settings Only run a PID tune after you have uploaded the new thermal settings to your printer.ġ1. The easiest way to do this is to use Repetier Host. In order to make sure the temperature reading is as stable as possible it is important to PID tune the setup. You can now select upload to load the modified firmware.ġ0. This figure is based on a typical x16 microstepping value.ĩ. You can further calibrate the esteps per mm later if need be. ![]() You will need to change the last figure in the #define DEFAULT_AXIS_STEPS_PER_UNIT Make sure thermal runaway protection is enabled. ![]() Never exceed 285☌ when using the thermistor with Hemera.ħ. Marlin has a -15☌ restriction on the maximum temperature able to be set on the LCD, so in order to hot tighten at 285☌ you will need to set the max temperature in the firmware to 300☌. the minimum and maximum temperate settings. Scroll down a bit further and you will find. If you skip this step the temperature will not be read correctly.Ħ. In this case X refers to whatever parameter you may have set. This means you are changing the temperature sensor type to a 100K thermistor - ATC Semitec 104GT-2 (Used in ParCan & J-Head) (4.7k pullup). This needs to be changed to #define TEMP_SENSOR_0 5 So I set this less the 41mm tool Y offset as the upper Y limit in M208, use M564 S0 at the start of each tool change file to allow movement outside this limit, and M564 S1 at the end. Scroll down until you find the Thermal settings. Due to the depth of the Hemera tool, the maximum available Y position for the nozzle is about +90mm, 10mm inside the edge of the bed. If you are unsure which to select you may need to contact your printer manufacturer.ĥ. Unzip the folder and open the Marlin.ino fileĬheck to make sure you have selected the correct board. Download the Marlin firmware Source files for your specific printer.Ģ.
