Printed in ABS. Acetone finish.
Looks nice JB and thanks for sharing your results.
I hope your warping with ABS is now more less with this update.
With my UM2 I haven't used ABS till now, only PLA and Carbon_Fil.
With PLA I start the fans around layer 15 (with a 0,1mm layer height) so the first layers are not getting the full fan speed.
The fans starting slowly around 15% until the max speed.
(result is, I'm getting less warping effect)
In Cura my settings for the the fans are:
I'm not sure if these settings will do the same with ABS.
printing ABS with the UM2 ist sometimes a litte tricky.
the fan stop warping but the single layers do not connect correctly. i have the best results with ABS when the fan is off and now i'm using a door and a "ultitop" cover for the UM2 to keep the temperature constant high in the printing-room.
BUT for printing in PLA your fan holder is perfect!
now i can print with 3600mmand more and the results are perfect. the surface of my printed objects is very smooth even when i set the layers to 0.2mm. i use Innofil3D PLA at 250-260°C.
thanks for your great work!
(and sorry for my english)
