So I’m running into continuous issues when printing this new PPA-CF material and can’t find much information on this. I’m printing at 60 mm/s at 300 degrees Celsius on a new 0.6 mm nozzle. I’ve set the z hop to 0.8 mm and retraction to 0.8 mm aswell. Other than those changes I’m using the hyper PPA-CF preset. The prints fail halfway each time. I’ve gotten one successful print at the very beginning but the sides came out scratchy. Since then another issue is the nozzle bridges gaps between edges and doesn’t appear to retract when needed, this results in the prints needing to be trimmed and the tree supports being fused to the print itself. I’m using a thin layer of Elmer’s glue and a textured build plate, I don’t have access to a filament dryer and would really appreciate any help or advice. The clogs don’t happen in the extruder they happen in the nozzle, when I try to push filament through the top of the nozzle it seems to be jammed up very tight. The most recent test i did the nozzle got so jammed I had to stop because I am unable to get it out. I’ve ordered a new set of nozzles that should arrive tomorrow but am wondering if any settings should be changed aswell. Thanks for the help!!

I have two K1 Max printers. I have solved just about every printing problem I have had except for bed adhesion. Some of the time the glue that I got from Amazon works but most of the time it does not especially for larger prints. Is it just normal to have to glue every print down. If I use no glue the filament does not stick. No matter what I use, pla petg Asa whatever. If it is normal what kind of glue do you buy?

Sorry for the title, trying to see if it draws attention.

I know values are pretty good below 0.5 but if possible I would like to get it lower just for the fun of it. I have a cartographer and a R3Men graphite bed. The printer is a K1 Max with a modded X rail gantry from Mils24.

I've already trammed it to the point it's all 0, which it's kind of visible on the image but for some reason the middle is higher. I've tried with a different build plate which kind of minimizes it but the bump is still there.

Has any one encountered a similar situation?

I had it rooted before installing upgrade and wonder if it is possible to do no since I need mainsail to send print remotely. So if anyone knows how to or has source please share.

Was doing a long print (testing something) and I didn’t put glue down so some of it shifted and caused the print to become a stringy mess.

But did the fail protection kick in? No…it’s just running its little happy ass around printing like my 2year old colors.

I am having a problem where when I try to print the printer will print the purge line and then give me an out of range error everytime. I was having the problem and then got an update and it fixed it for about 2 prints then back to having issues

Context:

-I have a K1 max with a cfs installed.

-i recently replaced my extruder but had good points before and probably 10-15 after the change.

-i have tried different models

-i have tried different filaments and different spool slots in the cfs

-i ran a self check.

Does anyone know what I can do to troubleshoot this?

I have a K-1 Max that has a lot of screws missing from the printhead. Nothing structural it looks like but the two screws that hold in the plastic piece at the top are missing and the screws that hold the gray cover are missing. Can anyone tell me what size fasteners I can get that will fit in these places.

Does anyone know what is causing this and how to fix it. I swapped the extruder gears as there was a tooth missing.

So the error text on the screen is [CL2537] The leveling sensor may have an external disturbance, please try again after resolving.

I haven't rooted the machine at this point - would that potentially help?

I can't see anything obviously wrong with the lead screws/etc and it's literally only done maybe 10-15 hours of printing since new. The error has been somewhat intermittent but currently after a power cycle, it is still doing it and so won't print. When I have got it to z home correctly, it has printed perfectly.

Any ideas on how to solve this or what to check are gratefully received - thanks in advance

I hope this is helpful. I've been struggling with this for a while.

I’ve been running a K1 CFS‑C for a while and normally use Creality Print 7.2, which handles toolchanges correctly. Recently I switched to Orca Slicer 2.4.2 because I prefer its workflow, but I ran into a pretty unpleasant issue with the stock Creality K1_CFS-C system preset.

When slicing a multi‑filament print (with purge tower enabled), Orca’s stock preset inserts two T# commands for the first filament:

1. One immediately after START_PRINT
2. Another at the beginning of the first layer

On the CFS‑C, two consecutive T# commands do NOT mean “stay on this bay.”
Instead, the CFS‑C advances to the next bay, which breaks the filament order for the print. Creality Print avoids this problem because it does not emit a T# at the start of the first layer. Orca currently has no option to disable that behavior that I could figure out.

I tried a bunch of different work arounds, and I think I ended up with a clean, reliable set of machine G‑code blocks that:

• Remove the redundant initial T#
• Keep the wipe tower behavior intact
• Add a small prime + XY nudge to stabilize the first brim after toolchange
• Avoid unsafe Z‑drops during toolchange

Below are the working G‑code blocks I’m now using successfully with Orca Slicer 2.4.2.

Fixed Machine Start G‑code

• ;---Machine start G-code ---
• START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature]
• M204 S2000
• G1 Z3 F600
• M83
• G92 E0
• G1 Z1 F600
• ;---End Machine start G-code ---

In the above, I removed T[initial_no_support_extruder] to prevent the redundant first-layer toolchange, and cleaned up temperature variables to Orca’s standard names, but kept the positioning and other commands that are still useful in this section.

Fixed Change Filament G-code:

• ;---Change filament G-code ---
• G2 Z{z_after_toolchange + 0.4} I0.86 J0.86 P1 F10000
• G1 X[wipe_tower_x] Y[wipe_tower_y] F30000 ; use wipe tower instead of fixed coordinates
• G1 Z{max(z_after_toolchange, 0.2)} F600 ; reduce risk of hot bed grind
• T{next_extruder}
• ; Tiny prime and nudge
• G92 E0
• G1 E0.6 F300
• G92 E0
• G1 X{wipe_tower_x + 0.3} Y[wipe_tower_y] F6000
• ;---End Change filament G-code ---

In the above I refined a couple things, and included the T command so I could control the order. In Orca Slicer, it looks like if you don't include the T command, then it automatically adds one after the block. I also tried using a gcode if statement to exclude the T command for the first layer, but it didn't work because of that.

I've tested it a few times, and has been working great. If anyone else is running a K1 CFS‑C with Orca, feel free to try this out. Happy to answer questions or help test further improvements.
