Some updates on my aforementioned problems. I can honestly say that I resolved both.
1. MakerWare != MakerBot Desktop!!! I upgraded to MakerBot Desktop from the Qidi Tech provided MakerWare software and am now slicing 5 times faster, can set minimum layer time, and a variety of other advanced options. This is so much better! I may or may not stay with the MakerBot software, we will see how far I can get my machine tuned.
2. I used ReplicatorG to update my Sailfish firmware settings... and low and behold, my max acceleration was set to 65,536mm/s^2 (yup, you read that right)! Coincidently that is the size of a 16 bit integer, or 2^16. Obviously an incorrect value, that caused my machine to behave as if it didn't have acceleration turned on. I changed that value to 1000mm/s^2, and the X, Y, and Z values from 1000mm/s^2 (default) to 500mm/s^2. MY GOD! Printing is almost buttery smooth! No more "ringing"! I also changed my ABS filament temp from the 230C to 220C, and my bed is now at 85C (I don't use an active cooling fan with ABS). ABS sticks perfectly to the blue sticker and does not warp! Very very happy with last nights result! I may use the spare blue sticker pad with the MagHold spring steel plate (in the mail to me now), because I am having so much success with it.
Things to do:
a. I may reduce the max acceleration parameter to 750mm/s^2, and the Y acceleration parameter to 400mm/s^2, instead of 500mm/s^2. The Y axis has a lot more mass, and should therefore have a smaller acceleration value than the X axis. Still need to decide on values for extruder acceleration. Still trying to figure out why there is a max acceleration parameter and then individual parameters for each axis...
b. I may also reduce my ABS filament temp further, say to 215C. I am working on surface smoothness and bridging next.
c. Install MagHold with BuildTak (option 1) and Blue Sticker (option 2)
d. The wire loom on the right side of the machine is rubbing on the right acrylic window when the machine moves in the Y direction. This is wearing away at the acrylic, and needs to be fixed. Thinking of printing one of those cable chains on thingiverse, just have to decide which one!
