Nozzle knocking over Skeinforge support material

Nozzle knocking over Skeinforge support material

Hi,

I have been exploring Skeinforge's support material recently and learned a lot about how to control it but I have one problem left to solve.

I have a case that I am printing which requires internal support. I have determined how to specify the width, spacing and extent of the support material and disabled the extra nozzle lift that accompanies support material by default.

The problem I have is that during the course of printing the nozzle moves over the support material and, because of its weak nature, it knocks the top of the support material and it detaches from the bed then topples into an adjacent piece of support material.

Is there any way of forcing Skeinforge to avoid moving over the support material (I have Comb enabled), or lifting the head a little while it does, so that I can avoid this happening in future.

Please do not suggest I use Slic3r. I have been following it through the recent RCs and 1.0.0 final release. When I slice this model with Slic3r, and view the GCode in gCodeViewer, it only appears to output support material every three, sometimes two, layers which seems somewhat broken to me.

Regards,
Neil Darlow

Have you tried enabling hop? That should lift Z on all moves.

Hi Chris,

That seems to be what I am looking for and you get a mention in the description too. I will give that a try and see if it helps.
