I cant figure out what I am doing wrong…
I bought a (very expensive) roll of Polydissolve S1 and have been trying to get it to work with my prints. I am using eSun PLA+ and experimenting with the Support Interface feature in Cura (using 3.2.27). I have tried a wide range of temperatures and feed rates, but my test prints fail every time. I am using the Dual Extruder V3 and printed the example gears with the supplied Polydissolve S1 without a problem. When I try to make my own prints, its garbage.
- eSun PLA+ model material in E1
- Standard print settings based off of Verbatim PLA (always works great - never had a failed print) with tweaked temps
- Bet temp from 60-70 Deg C
- Polydissolve S1 support material in E2
- Tried printing temps of 210-230
- Print speeds of 20-40 mm/s
- Flow of 95%-100%
Support infill is model material. The interface layers (roof and floor) are the Polydissolve S1 material.
- When Polydissolve material prints, it does not stick to the bed (regardless of temperature)
- Polydissolve material also does not stick to model material (regardless of temperature)
- Polydissolve material curls up when exiting nozzle and sticks to the outside of the nozzle instead of the surface below it
When these symptoms happen, the support material gets dragged around, and gets blobbed everywhere. It never stays where it should and eventually creates interference that cause the nozzle to crash into and, in some cases, break the print off the bed. My Polydissolve material came in a vacuum sealed bag with desiccant, but I noticed that it was very brittle. Is this normal? I can easily snap a piece in half.
I tried a new print with PLA in both extruders to ensure that there wasnt something messed up with the toolhead, and it printed out of both perfectly… So it appears to be a settings thing with the Polydissolve . I just don’t know what thread to pull next.
Anyway, any suggestions??
