Thanks - I am using PLA, with the following parameters: Layer Height .15mm Print Speed 60mm/s Travel Speed 150mm/s Initial Layer Z Overlap .15mm Temps are all at default settings I've re-calibrated my platen with the same results. Thanks in advance for any suggestions.

I started using a full raft with printing because of a warping issue that I was having. Now I'm experiencing an issue where the raft prints perfectly, but the first layer of the item I'm printing has a lot of weird issues. It almost looks like my platen isn't level - but the raft prints perfectly, as do all layers above the first true layer. I've attached an image to show the problem. Can anyone suggest what I'm doing wrong?

Is there a document that explains how and when to maintain a printer (including what and when to oil/lube various parts? I was surprised that there wasn't either a printed, or PDF, manual provided with my printer. I've been trying to get through a lot of the information here on Ultimaker's site - but there is a ton of stuff here between the forums, helpful videos, product information, etc. An overall document (manual) with links to more detail would be very helpful - and may be here - but I haven't been able to find it yet. Is there something like that?

I'm also new to the 3D printing world, but I found the following list of modeling software, as well as the categorization into artistic and engineering applications, to be quite helpful < https://www.matterhackers.com/articles/finding-the-right-3d-modeling-software-for-you>. I'm currently using OpenSCAD for my designs. I am working on building custom accessories for forensic photography, so need a fair amount of precision. So far OpenSCAD is working well for me, but I'm new enough to realize that I may end up with something completely different.
