I am just not having a good week. I have had every kind of printing problem there is in the past week and I thought I got it all sorted out with a new E3D V6 hotend but now I am having cracking issues.
I had to start over with a fresh install of the firmware and kinda screwed up my profile (Simplify3D) while troubleshooting so I am not sure if this is an issue with the firmware settings, profile or if something is still broken.
So, I have a heated chamber and cracks are normally very rare for me but now they are in pretty much every print.
This print was done with a .40 nozzle at 245c (bed 90c) layer height .26 the wall is 4mm thick (it’s a structural batter box) and 3 perimeters 100% infill (yea I wanted it strong).
So, besides heat what could cause this? Anything in the settings? It is cold here and I suppose it’s possible the heated chamber was cooler than normal but anytime I opened it, it felt very warm inside.
