11. Z lowers to bed a second time until the BLTouch stops it.

     

12. Z moves up and arm moves to the side of the bed.

     

🟦 If something in this sequence does not happen, hit the E-stop button in the UI or flip the power switch on the back of the printer off.

🟩 If this sequence happened correctly confirm on the next message.

🟨 Clear the next message to go to the next section.

🟪 A message will pop up and the arm should move the hotend to the center of the bed, just above the bed surface.

• Clear notification message.

   

🟦 A message will pop up with a jog panel.

🟩 Jog the nozzle up or down until the nozzle is barely touching the bed.

• Take the value the Z shows when the nozzle is touching the bed and write it down.

   

• This will be used after the setup wizard.

   

• Clear the jog panel.

   

🟨 Clear the next message to go to the next section.

🟪 A new message will appear and the nozzle will move to the corner of the bed by the circuit case.

• Take a note of the XY values for later.

   

• Clear the jog panel message.

   

🟥 Clear the next message to go to the next section.

🟪 This is a repeat of step 15, except now you should align the BLTouch probe to the points on the PCB.

🟦 After the section is done a message will pop up saying that the Heater Tuning section is next. Put the print surface back on the printer before clearing the message.

🟪 A message will pop up notifying that hotend tuning will start.

• Arm will move to the center of the bed.

   

• The hotend heater will turn on and start tuning.

   

• This can take 15 minutes. Don’t leave the printer, but you don’t have to watch it closely, just keep the Duet UI open and keep an eye for any error messages.

   

• Clear the notification message.

   

🟦 After tuning is finished a message will come up asking if you want to save the tuning to the config.

• Confirm the save to config.

   

🟩 A new notification message will appear that heated bed tuning will start.

• The z axis will move up.

   

• The heated bed will turn on and start tuning.

🟨 After tuning is finished a message will come up asking if you want to save the tuning to the config.

• Confirm the save to config.

   

🟪 After the notification goes away it should be replaced by a message saying the setup wizard is complete.

• Clear this message.

   

🟪 In the Duet UI, go to the “System files” tab

🟦 Open the config.g file.

🟩 There is a section titled “Z-probe”, go to the G31 command in it.

• Take the Z value you took note of in step 14

   

• subtract the value from the Z value in the G31 command.

   

• Example, if you wrote down a value of 0.5, the Z value would now be:

   

  • Z=2-0.5=1.5

     

• Example, if you wrote down a value of -0.5, the Z value would now be:

   

  • Z=2-(-0.5)=2.5

     

🟨 Change the Z value in the G31 command to the new one.

🟧 Save the config.g file.

• This step requires that you have setup the hub and UI. If not, come back to this after you get the other systems running.

   

🟪 Open the “printer calibration” panel in the UI.

🟦 Enter in the printer ID number in the top box.

🟩 Enter the point coordinates you gathered in the point boxes in the order you gathered them.

🟨 Click on the gear icon to go to the parameters section.

• You can check whether the points you input match the corners of the bed of the target points.

   

• You can also shift the output calibration by inputting into the offset and rotation boxes.

   

🟧 Select whether the values correspond to the BLTouch or hotend.

🟥 Click the “Calibrate” button.

• The UI will output a response when the hub finishes the calculations with the final error and calibration command.

   

• The command is saved to the printer, the command in the console is just for reference.

   

• The error is the solver error in calibrating the printer. An acceptable error is under 1, and a good error is under 0.5.

   

• Repeat the process in step 20, but with the XY coordinates you gathered for the BLTouch.

   

🟪 After you have the output config from the Excel file, go to the bltouch_configuration file in the macros tab.

🟦 Paste the output into the file.

🟩 Save the BLTouch configuration.

🟪 Go back to the “Printer Setup” folder in the “Macros” tab.

🟦 There is a file labelled “Manual bed level”

• Run this file.

   

🟩 The arm will move to the corner by the circuit case and a jog panel will appear.

• Move the Z down until the nozzle touches the bed, take note of the value.

   

• Press “ok” on the jog panel to continue.

   

🟨 The arm will move to the next corner and another jog panel will appear.

• Move the Z down until the nozzle touches the bed, check the Z value, it should be close to the previous value (+/- 2mm)

   

  • If the Z value is more than 2mm off of the previous value, move the Z up and try to adjust the leveling foot under that corner of the bed up or down until you can get the Z value the nozzle touches the bed at within 2mm of the previous value.

     

• Once you are done adjusting this corner, press the “OK” button on the jog panel to go to the next corner.

   

🟧 Repeat the previous instruction for the next two corners.

• Try to get each corner as close as possible to the first corner.

   

🟥 After pressing “OK” after the fourth corner, a new message box will appear saying the arm will run automated bed leveling to check your work.

• Press the “OK” button on this message to start bed leveling.

   

• The arm will run it’s bed leveling script, but just checking the four corners of the bed.

   

⬛ After bed leveling is done, go to the “Height Map” tab in the Plugings section of the Duet UI.

• This shows an exaggerated representation of the height data gathered by the bed leveling.

   

• Look at the “Maximum Deviations” line in the statistics section of the page.

   

  • The deviation should be within -2mm / 2mm

     

  • If not, you may want to repeat this step to improve the leveling.

     

🟪 Go to the “Jobs” Tab in the Duet UI

🟦 There should be a preloaded gcode file

🟩 Select it and start the print.

🟨 The Duet UI should go to the status page, and the heaters should start heating up.

🟧 When the print finishes bed leveling you may need to jog the nozzle up or down on the status page.

• Watch the print for the first layer or two (this test print will be fairly short)

   

🟥 Let the print run until something goes wrong or the print finishes.

• Congratulations! You’ve successfully assembled a printer! 🎉
