Printing Over 300 Degrees Issue

Flagship K Series Creality Flagship K2 Pro & K2

Printing over 300 degrees nozzle temp with the K2 Plus is driving me insane. I am trying to print with Fiberon PPS-CF at 320, and every time when the printer completes the self leveling and heats the nozzle to 320 it kicks an error and shuts down. Internal error on command : “BOX_MATERIAL_FLUSH” , “values” :[BOX_MATERIAL_FLUSH] "box_material_flush LEN=140 VELOCITY=360 TEMP=320: TEMP must not have maximum of 300. I am losing my mind. I have tried using the “generic” PPS-CF profile in the slicer and selected in the printer external spool holder, and with a custom material profile I made based on manufacturers settings for the filament. I have come to the conclusion the problem lies somewhere in my slicer settings/filament profiles/configuration but just cant figure it out. I have been printing for 7 years and have never had this much frustration - even back in the day of manual everything and fighting for first layer and dimensional calibration.

Any help would be be GREALY appreciated

I would say that Creality has some explaining to do. Did you open a ticket?

Well yea….have had a ticket open for a while. It started down the rabbit hole of replacing the toolhead cable, which did resolve the random disconnects, but now its appearing to be some rogue firmware or slicer setting thats preventing me from printing anything over 300 degrees nozzle temp, and I am trying to print with some engineering materials…

That is disturbing to hear, because the ability to print with engineering materials was a principal part of my decision to buy this model.

So far, I have not had a project that justified using engineering materials, but what caught my attention in your original post was your mention of Fiberon PPS-CF. That filament has been on my radar for some time. I just need the right project to justify the cost.

I can only imagine how frustrating it would be to invest in a printer for that capability, only to have it fail to deliver. I will be following this thread closely. Please keep us updated if Creality ever addresses your open ticket.

So I finally got some movement from Creality that made sense. I have inserted the code and am drying the PPS-CF to try again tonight…

"Latest update: Our R&D technical team has found that firmware errors were caused by differences in filament. We will optimize the firmware in the future to improve this issue.

Temporary solution:
Please go to the Fluidd settings and add the following macro at the end of the configuration file gcode_macro.cfg (as shown in the image):

Copy Code:

[gcode_macro BOX_MATERIAL_FLUSH]
rename_existing: BOX_MATERIAL_FLUSH_BASE
gcode:
  {% set temp = params.TEMP|int %}

  {% if temp >= 300 %}
    {% set temp = 300 %}
  {% endif %}
  BOX_MATERIAL_FLUSH_BASE LEN={params.LEN} VELOCITY={params.VELOCITY} TEMP={temp}
