1. What machine should I choose for the QIDI? Should it be the Flashforge Creator Pro or Flashforge Creator Dual?

2. With the Makerbot software, the head would start in the front left of the machine while the bed and extruders were preheating. Then it would travel to the front right corner of the build plate and lay down a "primer" strip from right to left. Then move to the center of the build plate and start building the model. However, with Simplify 3D, it starts in the front right while pre-heating. Now this is not a big deal but what happens next is weird. When the bed and extruder is done heating, it pumps out about 3 seconds worth of filament, straight down into the base of the machine (not on the bed). I quickly go try to grab and tear off this string so it doesn't mess up the print. Then it moves to the right front corner of the bed and pumps a little pile more, about 2 mm across right to left. Then it starts printing. I can't tell if it purposely is putting a pile there or due to timing, it's actually just the tail end of it pumping out filament. What is going on here?

3. Lastly, when it was done with the model and went to it's done position (this time right back corner), it carried a long line of filament with it. I know that extruders sometimes cant cut off filament cleanly but this was excessive. Any ideas?
1. I use the Flashforge Creator Pro as a starting template and then once I have some settings I like I do a Save As... and name it "Qidi - Some Description".
I suggest watching their video tutorials: https://www.youtube.com/playlist?lis...O7wODJpQBVf-Ss

2. Add the following code to the startup script tab. This will do the line on the front of the build plate.

3. I don't know. I've seen mine do something like that, but I haven't worried about it.
