Starting out tips for using the Palette 3 / Palette 3 Pro with the Prusa Mini/+

The tips below are intended to be used in conjunction with the Palette 3 / P3P getting started guide.

Firmware:  Update both the Prusa Mini and the Palette 3 / P3P to the latest released firmware before attempting calibration.    Note:  Check both the Prusa Forum and the Mosaic Form for any known issues before doing the firmware upgrade.

USB Connection Issues:  If you have problems with the USB connection between the Mini and the P3/P3P, do a factory reset on the Prusa mini / mini+.   If this doesn’t resolve the issue, then contact Mosaic Support.

WiFi Connection Issues:   The Palette 3 / P3P only connects to 2.4Ghz networks.  Some special characters in the network SSID will prevent the Palette 3 from connecting to Wifi.

Output tube / clip configuration:  The Prusa Mini doesn’t require attaching the guide tube clip to the extruder body.  Using the existing input tube makes inserting filament into the extruder.If you have the external filament sensor installed, remove it. Do not remove or shorten the input tube to the extruder.

  1. Use the short output tube (57CM).   Since the filament will be fed into the printer’s input tube the guide clip isn’t needed.  You can optionally put it on the output tube to make it easier to handle the output tube when inserting the filament into the printer.
  2. Enter the calibration data for the profile (assumes stock length Bowden and input tubes):
  3.                 Load Offset – 352 mm
  4.                 Output Tube – Custom Length – 76 cm    
  5.  Note:  The custom length is needed to adjust for the extra length of the printer’s input tube and to have enough filament to reach the extruder gears.  You can lengthen or shorten the output tube custom setting to adjust the filament length so that the printer will print a full purge line at the start of the print.  You can think of adjusting the output tube length to get the full purge line as setting the home position for the filament.  If you do need to adjust the length use 1 cm increments  and repeat as needed.

 

Canvas Settings:

  A. Enable the Serial Printing Screen on the Prusa Mini.

  1. Open the printer profile’s settings menu
  2. Click on Sequences (gcode)
  3. In the “Start of print” sequence add to the very first line: M876 P1    ;This causes the Mini to switch to the Serial Printing Screen.
  4. In the “End of print” sequence add to the very last line:  M876 P0    ;This causes the Mini to switch to the Main Screen

 B. Setting the Bowden Tube setting to reduce the amount of waste filament at the end of the print.

  1. Open the printer profile’s settings menu
  2. Click on Extruder.
  3. For the stock extruder and input tube, change the setting for Bowden tube length to 385.  Note: This setting is set properly when there is just enough filament let so that the extruder can move the filament to unload it.

 C. Link to my Mini’s Canvas printer profile so you can check my settings or import them: https://share.canvas3d.io/printers/f026c2d973ec2813e841c086acce33b7

Starting the print with Smartload:

  1. At the feed extruder prompt there should be a few inches of filament extending from the output tube. Place the filament into the printer’s input tube until it is against the extruder.  Note:  If the filament isn’t long enough to reach the extruder gear, that means the output tube length is too short.  You need to cancel the print and add a few cm’s to the output tube length setting.  If you just pull filament from the output tube, you will throw off the calibration, so the palette isn’t in sync with the starting position of the print.  This also applies to the MK3.  I know some of the palette videos have you pull out the filament, but not doing so saves a lot of time trying to get the splice positions back in sync.
  2. Don’t clip the guide tube clip.    The output tube will be pulled against the input tube of the printer.  Just click on next at the prompt.
  3. Click on smartload and make sure that the filament is being pulled into the extruder gears. You may need to give the filament a little push to get it engaged.  Look at the extruder gear (open inspection door) to make sure it is turning.
  4. Due to the length of the Bowden tube, it is possible/likely to have a timeout and have smartload stop with an error about no filament movement detected. Click on OK and then click on smartload again to restart the process.  Repeat as needed.

I have had my Mini+ for about 6 months now and could never figure out how to set it up with Palette 3 Pro. This guide is EXTREMELY easy to follow and works great. Thank you so much for this guide!

Does your printer ever just stop moving when using the P3P? Mine does every so often during a print and doesn't move again until I hit pause and resume a few times. Sometimes even that doesn't help.

I haven't had any freezes since Palette 3 firmware v22.04.19.0

I am currently running v22.06.02.0 and will upgrade to v22.08.11.0 in the next few days.

Also does your startup gcode have M876 P1  in it to set the serial print screen ?    This sets the display input for only selections available from the serial print screen.  Menu selections from other menu pages can confuse the palette 3.

What slicer are you using ?   Canvas or PP2P with Prusa slicer ?

I am running v22.08.11.0, but I had the same issue with v.22.06.02.0. I have had the same issue before and after adding the M876 P1 line to the gcode. I am using the canvas slicer.

I just managed to set up P2PP and ran this print.

The transitions all came early and it stopped making filament too soon, but it mostly worked, no pauses.
