Hello fram FRANCE

[GRIZET]

I am a professor of mechanics at ENIT (National School of Engineers of Tarbes)
I bought a Rodstock Delta in January on the site, which was delivered to me and that was mounted by students. It works now.
I own 2 other 3D printers, RepRap Mendel one which was carried out by students and 3D toutch 2 heads for 2 years
Regarding the Delta, for the moment, it does not print quite good geometry. That's about it I'm looking for help on this forum.
I do not know too much or post my request on this forum (especially since English is not my first language ... and I'm not familiar with forums)
I can illustrate my problem, I hope you will guide me to the forum
The best thing is to show you my picture problem: I have the outline of my pieces that do not follow the fill area. I think the filling area is right but the outline is slightly separated by place and it's not going right
Is anyone has any idea why this default?
