Welcome to the SeeMeCNC Community

Hi ya'll,

We have a recently built Rostock Max V2, which has made 4-5 parts so far. Everything is looking pretty good in the quality of the parts. Yesterday I printed the attached pics, please notice the de-bond between a few of the layers. Do you have a suggested tweak that would prevent this, to create a fully uniform layer? I am not sure what to suspect, as I have read that the Delta configuration can sometimes be a hard-to-detect initiator of some of these problems (binding, squareness of posts, ujoint friction, etc).

The material was ABS Pure from MatterHackers. The nozzle was at 228C, while bed was at 80C. MatterSlice was the slicing engine, with 10% infill, all other settings in the configuration unchanged from the SeeMe stock settings loaded from their site.

Thanks for your advice in advance.

Your only real option is to print hotter.
The strength of the bond is a function of how good the weld is between the layers, the layer being deposited has to be hot enough to remelt the already deposited layer.
Obviously for weekly bonded layers the warping forces can overcome the poor welds between the layers.
FWIW I usually run ABS as 240+ but I'm not using the stock hotend. I'll also go hotter than that if I need something structural from ABS and run a fan to help with overhangs.
The conventional wisdom is no fan on ABS but IME that really only applies if your temperature is borderline.
