Topic: Hollow print, loose 'skin'.

I printed the Pink Panther Woman, full size, no infill, 4 perimeters, .3 mm layer height. In the curves toward the center, the filament leaves gaps, as can be seen in the photos. What could I do, other than not print it hollow, to prevent this? Also, when the print was done, the z axis moved past 150 mm and kept going, grinding the gears inside the motor until I hastily hit emergency stop. The number for the z axis showed 163. Is there something in the software that I can set so that large prints don't drop the bed past this limit when the print is done?

Re: Hollow print, loose 'skin'.

Turn on infill and set it to .1 or something, I think that's the issue.  You're printing unsupported.  Probably could do it with a fan mod too. 

For high prints I edit the gcode file manually to get rid of the last z movement or minimize it.  There's probably an easier way but that works fast and I don't have to mess with any other settings.

I used 5 perimeters, hollow print.

The bed trying to lower itself is something in your end gcode.

Re: Hollow print, loose 'skin'.

Since you don't have any inner printing going on it doesn't leave much time for the outer perimeters to cool... so either slowing the print speed down(might not help too much) or the fan mod(I think this would help the most) Also how is it drawing the perimeters? inside to outside or outside to inside? makes a difference on the sloped areas....

Re: Hollow print, loose 'skin'.

lol...
I was going to do it again, and try 6 perimeters, and still keep it hollow.
And it does print inner to outer. Can this be changed in slic3r??

kISSlicer will print from outside to inside I believe.  Might be a solution but you will have to set it up properly.
