I would like to know what are the bests settings I shall use on my ULT 2, to print black ABS filament ( NEOfil) without Wrapping, It’s a flat object, not really complicated but it is large and flat so… it doesn’t help.
II tried everything, 3d Spray doesn’t work, up the buildplate tempeture, i need you !
You’ll probably need to run it real slow if it’s large and flat, and either print an airflow guide so that you don’t chill your nozzle or run the fans pretty low. Also, I recommend using acetone and a slurry puck to prepare the surface–print one and follow the instructions on how to use it.
What is the speed of your cooling fan? What i mostly encounter is that the fans are spinning too fast… I am spinning at 70% fan speed. And always use a brim of raft een printing ABS or HIPS
Also relevel your bed just to be sure, set the bed a little higher ±5degrees and clean the glass, use a brim or raft. 40mm print speed. And 65 to 75% fan speed.
I will give this a try this evening. I need to re-print that fan mod in ABS as mine was done in PLA and currently is heat-warped which sometimes causes issues with prints now because its starting to sag. But I had been unable to print it in ABS because it kept warping and coming off the glass.
Yeah, bed leveling is key here. I recommend you print an object with a big raft and try leveling the bed by hand as it prints the raft. You should see the line of ABS put down by the print head be smushed a little bit as it extrudes, and the lines should just be touching. This will ensure that you have enough pressure put down on the bed itself for good adhesion. The bed level procedure that the UM2 comes with will only get you approximately level.
I heard some people had good results with that stuff. Strange. However, build plate temperature is by far the most important, make sure that’s high enough.
