Flashforge Creator X and a few minor issues

[Mthompson]

Greetings all, I have a Flashforge Creator X, glass, ABS slurry, FF ABS, 110/230 temps, S3D and I have a few items I need to address:

1) Regardless if I am using left or right extruder, right before the actual print job starts, it feeds out about a foot of filament from the right extruder. I assume this is being done to prep my filament. So would be nice to know how to make it change to the left extruder when using that extruder.

2) I made a small LED Bezel in Autodesk Inventor. See attached. Bed is leveled after each run for the most part. Print never lifts up. But for some reason the walls are concaving the walls. The attached image was actually printed flipped 180degrees. Turned it over to also show how its adding peaks to the corners (note not flush table). All

I have downloaded a few items from thingverse with great success...but cant seem to get my bezel to print proper. Any suggestions would be GREAT!!!

Much thanks in advance

P.S Spoke via email to Flashforge and they suggested either upload project to TinkerCAD and download the .stl, splice, and try to reprint...same results. Even recreated it in TinkerCAD, spliced in S3D and tried to print that very....same results. So it is either a printer setup or S3D setup.

I run my hotbed at 100 to start and then for some materials (abs is one) I lower the temp to 90 at layer two. The hotbed on this machine seems to report a temperature closer the actual temperature than on some other machines. ABS has a glass point around 90C so when it's too hot the walls shrink in the first 5-10mm warp.

Much thanks for the reply. I will give it a go.

Perfect. That seemed to resolve my issue. Sadly though, my glass chipped in a few places on this initial dual stage temp change configuration . ABS parts are mainly removed once bed gets to room temp...due to being away from print job. I use the thick glass from Flashforge for reference. I will be flipping it over to continue to be able to print proper. I see there is a different type of glass that can be purchased that handles temp changes more friendly, bio.....something on ebay for like $25-30 is this the same glass as other glass/ABS designer are using?

Anyone have a thought on the other point of the prepping of the ABS only using the Right extruder?

Much thanks again!

I just got a couple standard 1/4" glass pieces from the local glass shop for a few bucks each. Never had an issue with them. I put a sheet of kapton then abs juice then print away.
