About

By default, FLSUN does not use builds from official GitHub repositories. Updates point to Gitee repositories which are very slow, sometimes inaccessible and not updated. In addition, during Delta Calibration, tower angles and delta radius are never recalculated in their Klipper build, which can cause several issues.

This procedure explains the whole process in order to obtain Root access on the Speeder Pad, to configure it correctly with optimized printer settings.

This settings are compatible with FLSUN Speeder Pad.

  • Useful and automated macros with notifications to KlipperScreen
  • Configuration for ADXL345
  • Improved Start/End Gcodes
  • And more...

Before using Klipper please read this documentations:

Note: Changes in the KlipperScreen.conf file only have an effect on the first configured printer, it's not needed on others.

  • Restart Speeder Pad and printer to take effect.

Note: You can select printer you want at startup on the screen. You can also enable default_printer setting in KlipperScreen.conf to start directly on printer you want and switch to others with shuffle button on the left side.


Get USB Serial from Motherboard

  • Connect your printer to one of the Speeder Pad's USB ports.

  • Connect in SSH then enter the following command to retrieve the motherboard USB serial:

cd ~ && ls /dev/serial/by-id/*

  • You should see the USB serial appear like this (serial is different depending on the motherboard):

  • In case you use same multiple printers connected on the Speeder Pad and you only see one serial when running this command, enter this one instead:

ls /dev/serial/by-path/*

  • If the second command shows multiple results, adjust the path of the serial accordingly, so all instances of /by-id/ should be replaced with /by-path/.

  • Go to your Mainsail Web interface then click on Machine tab.

  • Open printer.cfg file and find [mcu] section.

  • Edit the following existing line with serial you have just obtained like this:

serial: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0

  • Click on SAVE & RESTART at the top right to save the file.

  • Your printer should connect to your Speeder Pad.


Fix Shutdown button in Mainsail

Shutdown button in Mainsail only restarts the Speeder Pad because some distros don't support poweroff function and this is the case for the Ubuntu Operating System.

To correct this, in the SSH command prompt window, enter the following commands (one at time):

cd ~/moonraker/scripts

./set-policykit-rules.sh

sudo reboot

  • After reboot, go to your Mainsail Web interface then select the Machine tab.

  • Open the moonraker.conf file and add the following lines:

[machine]
shutdown_action: halt

  • Once done, click on SAVE & RESTART at the top right to save the file.

  • The Shutdown button now properly shuts off the Pad.

Slicer Side Changes

  • Change your Start and End Gcode in your Slicer settings like this:

    • For Cura:

      • Start Gcode: 
        ;Nozzle diameter = {machine_nozzle_size}
;Filament type = {material_type}
;Filament name = {material_brand} {material_name}
;Filament weight = {filament_weight}
;M109 S{material_print_temperature}
;M190 S{material_bed_temperature}

START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0}
      • End Gcode: 
        END_PRINT

    • For PrusaSlicer / SuperSlicer:

      • Start Gcode: 
        START_PRINT BED_TEMP=[first_layer_bed_temperature] EXTRUDER_TEMP=[first_layer_temperature]
M104 S[first_layer_temperature]
M190 S[first_layer_bed_temperature]
      • End Gcode: 
        END_PRINT

    • For LycheeSlicer:

      • Start Gcode: 
        START_PRINT BED_TEMP={bed_temp} EXTRUDER_TEMP={temp}
      • End Gcode: 
        END_PRINT

    • For Simplify3D:

      • Start Gcode: 
        START_PRINT BED_TEMP=[platform0_temperature] EXTRUDER_TEMP=[extruder0_temperature]
      • End Gcode: 
        END_PRINT

    • For OrcaSlicer:

      • Start Gcode: 
        START_PRINT BED_TEMP=[bed_temperature_initial_layer_single] EXTRUDER_TEMP=[nozzle_temperature_initial_layer]
M104 S[nozzle_temperature_initial_layer]
M190 S[bed_temperature_initial_layer_single]
      • End Gcode: 
        END_PRINT

  • Firmware retraction gives an advantage compared to Slicer retraction, it can be modified during a print (from Mainsail or KlipperScreen) and therefore the same gcode can be printed with different parameters without the need to be re-sliced.

    • For Cura, it's needed to install Klipper Settings Plugin (available here: Klipper Settings Plugin) and enable Enable Firmware Retraction setting like that:

    190531375-dc2def8d-9190-47c8-ae6e-bc7efaf2ce04

    • For PrusaSclicer / SuperSlicer, you just need to enable Use firmware retraction setting like that:

    Capture d’écran 2022-12-12 à 03 21 47

    • For OrcaSlicer, you just need to enable Use firmware retraction setting like that:

Calibrate your Printer

This calibrations can be done by Mainsail Interface with Macros or on Speeder Pad directly.

  • Calibrate your extruder by calculing Rotation Distance (see this documentation : Rotation Distance | Klipper)

  • Calibrate Z-OFFSET with Z_OFFSET_CALIBRATION macro.

    • ⚠️ The leveling sensor must be connected for this operation !

    • This function performs a palpation on the bed, then raises the hotend and starts the manual adjustment function:

    • Then remove the leveling sensor and using a piece of "copy machine paper" between the bed and the nozzle, adjust the height of the Z until you feel a little friction when pushing the paper back and forth. This helps determine the actual distance between the nozzle and the bed.

      Note: Prefer to use the buttons in the ADVANCED section, they are more precise and this could prevent the nozzle from forcing on the bed.

    • Once these steps are completed, you can click on ACCEPT to validate the Z-Offset measurement.

    • It's necessary to save the configuration by clicking on the SAVE macro.

  • Calibrate ENDSTOPS with ENDSTOPS_CALIBRATION macro and save the configuration by clicking on the SAVE macro.

  • Start DELTA CALIBRATION with DELTA_CALIBRATION macro and save the configuration by clicking on the SAVE macro.

    • ⚠️ The leveling sensor must be connected for this operation !

  • Start BED LEVELING with BED_LEVELING macro and save the configuration by clicking on the SAVE macro.

    • ⚠️ The leveling sensor must be connected for this operation !

  • Start BED PID with PID_BED_65 macro and save the configuration by clicking on the SAVE macro.

  • Start HOTEND PID with PID_HOTEND_220 macro and save the configuration by clicking on the SAVE macro.

  • After all the calibrations done, I recommend to apply a Safety Offset of 2 mm via the SECURITY_OFFSET macro.

    This could prevent the nozzle from scratching or sinking on the bed in the event of an incorrect adjustment of the Z-Offset.

  • After performing all printer calibrations, then start a print and adjust the first layer using babysteps via the Adjustments button in KlipperScreen or via the Headline section in Mainsail:

  • ⚠️ Don't save the Z-Offset value, a macro save automatically this value in the variables.cfg file and reload it automatically when Klipper starts:

  • You can find a test STL to print to fit your first layer here: First_Layer_Test.stl
