Just on my first larger print I learned a few lessons: 1. Check every setting on every tool. It's easy to miss one. 2. When one small part of the printed object will use 1 tool, if possible, orient the object on the bed so that the tool does not have to travel over the entire object and instead goes right to the area it will print on. Less chance of drool hitting the object where you don't want it. 3. Lower your temps. You only need it hot enough to fuse to the previous layer. No more heat than that is needed. Less heat, less drool. 4. Bondtech's are WAYYYY better than Titan's. Sorry, I know this is an e3d forum, I'm just sayin. I've already had to do a tear down of one of the brand new Titans and it was a major PAIN! I've got 5 Bondtech's and have never had to do what I had to do to this Titan. I have found that with the Titan it is possible to have a filament that is never comfortable in it. The idler is either too tight and the filament get distorted and has trouble flowing through all the PTFE tubing or too loose and it slips. Also, the screw on the tension arm slips on all four of the Titans I got. and... there's no visual indication of how tight the screw is. You have to feel it by using your thumb to open the idler arm.
