## **Firmware Upgrade Method - For current beta version only**
1. Download the high-speed firmware version and save it to a USB flash drive.
2. Insert the USB flash drive into J1 and select Settings - Local Upgrade - USB - select firmware file on the screen to start the update.
3. If your original firmware version is lower than V2.1.11\_20221111, after the firmware update, you need to run all calibration procedures again from Calibration section on the screen. If your original firmware version is V2.1.11\_20221111 or higher, you don’t need to run the calibration procedures again after the update.

## PLA Profiles - For High-speed Firmware Version Only
# Notes:
- J1 max. speeds are: 350mm/s print speed with 10000mm/s^2 acceleration. In actual printing, especially for new users, the printing success and print quality should be guaranteed first. Therefore, the profiles provided here balance the print quality, the heat dissipation performance of the printer and the max. flow rate of the print head.
- Different layer settings, corresponding to the maximum attainable printing speed is different, the relationship is as follows:
- The printing speed is limited by the characteristics of materials, some materials such as TPU, breakaway supports, and PVA can not achieve high-speed printing (otherwise it will cause poor print quality, blockage problems), currently the most common material to support high-speed printing is PLA (esun ePLA - matte or wooden PLA speed needs to be properly reduced) and ABS.

@Jade When will we be getting access to Lava Studio? I ordered my J1 yesterday and I would really like to start taking a look at the slicer to understand the workflow while I wait.

Sweet… any update on the expected release date of Luban for J1? This thing is amazing, and I’m excited to get started with the software as well.
Thanks!

Prusa Slicer profiles are quite broken.
The right extruder does not heat up. When it is used it cannot extrude and the machine complains about a lack of filament, so the runout detection is working. I continued by heating the extruder manually and going through the filament load process. I reusme the print.
But the left extruder has not parked! Both extruders are over the wipe tower. I Cannot complete a print because because the extruders only print what they can reach (thankfully they do not collide)

Sounds like you might have a profile issue. I’m using the 0.3.0 plugin, and it’s working great. Haven’t changed a setting yet. Maybe reinstall / recalibrate?

Ah, I see, I think I know what happened.
I have quite the collection of filaments in Prusa Slicer, I figured I could just pick any of those. However, it seems like the preset for J1\_Left\_Nozzle and J1\_Right\_Nozzle are mandatory, as they include the custom gcode sections that make the extruder switching work.
Perhaps they would be better included in the machine custom gcode ‘tool change g-code’ section, then I could use any of my existing filament profiles without having to duplicate them for each side of the J1
The extruder changes are also slow due to the extra M109 in the ‘end g-code’ section. I dont think that is required, the parked extruder is never told to cool, thus does not need to wait to heat for 5 seconds before every change

I have made these changes in my own Prusa Slicer configuration, and it working quite well. I can use whatever filament I want, and the machine section takes care of the tool change gcode. The last issue I am facing is a long-standing bug in prusa slicer where it fails to emit an M106 for the second extruder. Can be fixed by setting to a constant speed, but that doesnt compare to Prusa Slicers auto fan speed stuff.
Overall I would say Prusa Slicer is not particularly well suited to multi-extruder machines at the moment. For example, the prime tower is a single volume for all materials, which will cause problems when one of the materials is designed to not bond so well (such as breakaway support material). Cura solves this by only priming each material onto itself. I expect this to get better with the eventual release of the Prusa XL.

I am not sure I have update cura properly but it has had multiple problems with adhesion and the finish of the side walls.
I tried the PrusaSlicer and all the adhesion problems have gone away. however there is one serious issue. In the fast mode the print head suddenly raced to the front of the printer at full speed (or close to it. it was very loud) and slammed into the front wall and then continued to extrude the filament. I did not see it for the first part of a 7 hour printing but saw the result 2 hour into the print. The print continued and eventually looked like the correct layers with a really messy intermediate layers where it tried to build a foundation. I would be happy to share pictures and the gcode file for debug. When i shifted to fine mode it worked fine. The parts it produced for other designs are much stronger than those from the Cura slicer.

@skinnermp @GrumpyOldGuy Hey guys, Luban is ready for J1 now. See this topic and download: [Luban V4.5 Beta.8 Supporting J1 Is Available for Downloading](https://forum.snapmaker.com/t/luban-v4-5-beta-8-supporting-j1-is-available-for-downloading/28469)

Why does the prusa slicer profile not use the M2000 gcode to stow the printhead? I see that Cura and Luban are both using it for the start-nozzle gcode, but the prusa slicer profile is manually moving the printhead to the stowed position.
Unfortunately, the prusa slicer profile induces Y drift. Multimaterial prints are not straight (I am using firmware 2.2.13). I know the machine is good, because the same multimaterial test print comes out OK sliced in Cura/Luban.
I have tried to add the M2000 gcode to prusa slicer, but upon changing from T1 to T0, T1 moves to the stowed position, then returns to the print area and violently collides with T0. I have tried to compare the tool swap sections of gcode between prusa slicer / Luban, but cannot spot any meaningful differences.

can we get some guidance on using M2000 to perform tool swaps
