MINI+ & Proto-Pasta filament issues

I just received my MINI+ last week (decided I wanted a small form factor printer in my office) and after first layer calibration everything has been super great until I try to print with Proto-Pasta filament then it all goes into the compost heap.

  • Inland PLA/PLA+? No prob
  • SunLu PLA? No prob
  • MatterHackers PRO PLA? No prob
  • eSun PLA+? No prob
  • Inland PETG? No prob
  • AmazonBasics PETG? No prob
  • 3D-Fuel Standard PLA? No prob

 

Any of my Proto-Pasta spools print just fine on MK3S+ and Ender 3 V2 (qty2) units - take the spool and load it into the MINI+ and click click,  material in the extruder and failed print. And it happens before any first layer completes. Purge line is clean but anything after that is just a mess on the build plate or nozzle.

I have only had this printer about 5 days but I have already done more than 40 hours of printing and only Proto-Pasta is giving me headaches.

What have I tried?

  • Generic PLA profile - same issue
  • Prusament PLA profile - same issue
  • slowing down print speed: 90%, 80%, 70%, 50% - all have same issue
  • increasing hot-end temp: 5C, 10C, and 15C - all have the same issue
  • I have done combinations of the above with 100% failure

 

For PrusaSlicer I have created a few shared filament profiles and I haven't had a need to make a dedicated Proto-Pasta profile. These profiles are used on the other printers (mentioned above) without issue. All of them started with Generic <type> then assigned to all printers after minor modifications. Things are dialed in enough so far for me. It works on 3 other printers from 2 manufacturers and yet MINI+ blows chunks.

As soon as I clear the extruder of the particulates I can load any other filament and fire off a test print without hiccup.

Thoughts?

I have had similar results with several filament brands and types.  I am not sure why some will just not print in the mini.  Fusion filaments and Protopasta have been a bugger.

I had some Proto-Pasta issues a little while ago with filament, immediately after opening the bag, was 'wet' and needed time in a dryer before things were good. At the time it was 3 spools out of the 10 I had. It was so very frustrating.

I was hoping that I could just 'what am I doing today?' and then grab a spool, slice up, and print. Guess the MINI+ will be relegated to things without the shiny, awesome, glittery, colors of PP.

I just completed printing 2 spools of iron-filled Protopasta PLA on a Mini+, no problems at all.

However... I have a Bondtech dual drive extruder (more precisely, its Trianglelab clone). I think the stock extruder is for whatever reason just not as forgiving as the Bondtech.

I doubt that is the only thing.  I have had success with protopasta also.  It is only one roll for me.  That same roll prints fine on my Mk3S.

What color are you printing?

I'll keep that in mind (referencing extruder upgrade)

What color are you printing?

  • Blood of my Enemies Red
  • Marine Dream Blue
  • Forest Fantasy Green
  • Citrus Sunrise Orange
  • <and have at least another 15 spools of different colors>

Any and all fail on the MINI+.

The 4 colors I mention by name were for a mothers day project. Having a 4th printer would have shaved off some time for me but original planning was for just the 3 printers so I made it. Whew.

Probably something different for me.  I get Nebula Galaxy and Orange sunrise to print.

Maybe I'm just bad at this 3D printing thing.. 🙂

Practice makes better.  There is rarely a perfect in FDM printing.

haha, yep. That's why I went down this path cause I wanted something that would be challenging and allow me to be more creative.

Other option was a wood shop but I couldn't justify the cost (or the space).

I have a decent wood shop.  I have a CNC, laser cutter, bandsaw, table-saw, and router.  The 3D printer allows me to do things that I could not do before.  Enjoy!
