Pro PCTG Print Profiles

Comments

    I'm having a pretty frustrating issue with oozing with this PCTG on all of my MK3s+ (stock and Revo6).  its to the point where id say 50% of my prints fail either by crashing or just making a huge blob of filament on the hotend.    Is there a profile available for the MK3S+?  

    I have tried a generic PCTG filament preset and modified a PETG preset with no luck.  I have adjusted temps, cooling, speeds, and I'm about to start tweaking retraction to see if I can figure something out but would love some advice if you might have something other than what has already been posted.

    I would love some print profiles for Prusa Slicer. I'm currently using Prusa XL with various nozzle sizes.

    I am looking for print profiles for the Prusa line of printers, particularly Prusa Slicer.

    Another for Pruss Slicer and the MK3s+-MK4s printer lineup.

    I use the satin sheet (https://www.prusa3d.com/en/product/xl-satin-powder-coated-steel-sheet/) for anything not PLA essentially precisely because Prusa says "don't or you can destroy the PEI sheet". I have the MK3S+ and primarily use the Prusa XL (the one with the boogery nozzle: https://www.amazon.com/Diamondback-Nozzles-Compatible-Polycrystalline-Extrusion/dp/B09X61NG5S).
    PETG and PCTG stick nicely to the satin sheet while PLA is borderline ("eh it's alright"). The PCTG is the only one offhand I can recall being boogery. The others just get really stringy/hairy.

    Are there any 'process profile' tweaks that you would recommend or just stick with the stock settings?

    I cant seem to find the Engineering print surface on Bambu Labs Website anymore.

    ConnorB,

    Which Prusa printer are you looking for a profile? We may be able to build a profile for a specific printer.

    Otherwise, I recommend that you start with a PETG profile and set the hotend temp to 260C and dial it in from there.

    Jon Fernandez,

    I recommend the Bambu Lab Engineering print surface. Or, if you use PEI, make sure to use glue stick as a release agent otherwise it will stick too well.

    what print surface do you recommend for this I have 2 beds with missing chunks now I'm printing on painters tape now haha

    Where do the downloaded files need to be copied to show up in Bambu studio?

    Having the same problem as Grant, above. Lot's of blobs in the middle of the model. Can't figure out the proper configuration.

    Hey Jim,

    I have found the best settings for me to minimize the oozing and blobs is to lower the temp to 250, turn my retraction up and my print speed all the way up to 250. What printer are you using? I also have my bed temp up at 80 and use bed weld to minimize warping. I notice better results when printing single items vs multiple items. I can upload my exact print settings for my prusa in a little bit.

    I'm using a Bambu P1S. I literally just tried lowering the nozzle to 255 and the prints are a lot better at print speed of 200. Bed is still at 70 with a textured PEI so things stick pretty good. What's your max volumetric setting? Basically, this is pretty much my PETG settings. I guess that make sense considering the lineage.

    So my changes worked for a single print, then I started getting A LOT of stringing when doing multiple models at once. I ended up using the settings overrides found here: 
    https://forum.bambulab.com/t/good-pctg-profile/28336 

    This helped with the stringing. I have 2 models printing right now and I don't see the same stringing going on so far.

    I can see those helping. I also get more issues when printing multiple parts at once.

    I might give your retraction settings a try. I am only at
    Length - 0.8
    Speed - 35
    Min travel - 1

    I wonder if wiping while retracting would help with printing multiple parts…..

    What is your volumetric speed set at?

    Mine is at 22.

    I had mine set to 10. my new prints came out 99% perfect. No stringing at all between models and maybe only one small blob.

    I bumped it up to 15 and started to get little hairs again.. so I think somewhere between 10-12 is good for me.
