Tip#1: for using a FlashForge Finder: When inserting filament, don't stop when you feel a little resistance, keep pushing for about 2 inches 40-50mm) until you can't push any more.
Tip#2: If you get the "Something went wrong during slicing" error, try changing the location of your saved .fpp and/or .gx printing files. Mine were initially going to the MacintoshHD... changing the file location to Desktop fixed the issue.
Tip#3: To determine if a model is causing a slicing error, load one of FlashPrint's internal testing models under File/Examples - if the file prints, the issue is with your model OR where you're exporting the .fpp and/or .gx printing files, not with the FlashPrint software.
Tip#4: Most people recommend fixing a layer of blue painters tape to the platform surface, allowing for easier removal of your print. My printer came with a purple (dried clear) glue stick - liberal application on the painters tape helps smaller prints adhere nicely. I almost always print with a raft or brim. When printing larger, denser models, the painters tape can and does lift up due to the concentrated heat (the PLA and extruder head are both 220º... that's hot!), causing the PLA to be applied at a different heights, resulting in distortions in the printed piece. i.e.: one of my pieces is a 4" cylinder with a center 2" hole that I first printed upside down. With the painters tape and glue stick, the entire top printed with a slow curved top, tallest in the center. It looked cool, but it was uneven and no part was the actual designed height. It wasn't until I got brave and printed directly to the platform that my model retained its true dimensions. The flat bottom of a smaller 2" diameter piece, even with a raft, painters tape and glue stick, continued to print the bottom in a slow arc - I have to print it directly on the platform's unheated surface, adhered with glue stick.
FlashForge's tech support person, Tang, is friendly, helpful and responds in a day or so. While having an issue, I made a suggestion regarding their set up and the process of motor removal when checking for a clogged extruder. I also told him about the Cheetah3d forum and it's helpful members and suggested FlashForge create an open user forum. It seems you learn by experience with 3d printing... an open user forum might help speed everyone's process. When I recommend Cheetah3d to others, I tell them the real reason to try Cheetah3d is the forum. I really appreciate all of your efforts.
