3mf CURA parameters to print PVA NATURAL supports properly

[EPALMI 2]

Dear all,

 

I'm kindly asking for *.3mf format file to CURA parameters to print PVA NATURAL supports properly.

 

I'm using though PLA in extruder 1 and PVA NATURAL in extruder 2 for supports, but the PVA NATURAL blocks and melts deficiently when constructing small latice supports.

 

Please, can anyone send me a file including the appropriate CURA parameters in order to print though PLA - PVA NATURAL combination.

 

Thanks in  advance for your attention

Please post a picture.  90% of issues with PVA is due to insufficient drying.  Despite using lots of desiccant I have to dry my PVA before every print.  I set the heated bed to 60C. 

 

I look in cura to see how many meters are needed (in bottom right corner hover over on the "i" in the circle).

 

Then I unspool that much and put it on the hot glass with the spool on top of that.  Let it dry for 4-8 hours before printing.  You should see different results.

 

Please post a picture.

 

Wet PVA prints snowier.  Whiter.  Dry PVA is clearer.  Very wet PVA sputters and crackles and you can see the steam.
