Hi All @Rainie
I suspect many experienced users already know this. As a newbie, experience is teaching me, which I will share with other newbies.
In using the Snapmaker supplied filament all went well with the most of the standard print settings in Snapmaker3D. I purchased a number of small 200gm filament reels locally from a reputable store to test them before buying larger reels.
I used a red coloured PLA and it printed the small picture easel project with success using standard settings with Raft and Touch Buildplate Support. I tried their white PLA to print the same project, same settings and the result was a fragile easel that easily snapped in a few places; see foreground of photo.
This was my chance to play with a few values in the custom setup. See highlighted values below; reprinted the easel which you can see standing in the photo above. It came out far more robust and did not snap as easily… yes I applied some force to test it. So slowing the print speed and raising the temperature helped… I have so much more to learn.
Keep having fun.
