I have an interesting speed upgrade that may be of interest for further discovery?
have been seriously upgrading my Ender 3 Pro…
Systematically, I have been watching the effects of the changes and how one step forward usually means a couple backward too!
I have a model that consists of a honey comb structure (frame of an airfoil for my UAV design) to print. I have cut it into pieces to allow printing a 600mm long x 400mm chord wing two bits at a time 200mm long (high on the build plate).
The outer walls are 0.9mm and internal structure 0.4mm wall.
A 200mm long section 2 pieces took 14 hours to print 60mm/s 0.2mm layer.
Initially I lightened all the “things” I could and ised all the slicer advice I could muster, but read an article on “The 100” boat race project….Ahhhaaa!
The ole Subaru and Porche trick, place everything with weight below the build plate.
The power supply is now hiding underneath the print bed at the rear and the filament holder/spool hides under the desk on quick release clips in a drybox jerry rigged from a 4 dollar plastic tupperware box!
Lowering the center of gravity is the answer, adding carbon fiber tubes connecting the top rail to the bottom frame, I think I can get to 200mm/second, maybe need a direct drive…but under extrudion has not reared its ugly head yet?
With these two changes I can now print at 140mm/sec, 0.45mm wall thickness, and 0.3 layer height. Increased filament flow to 115%. 6mm retraction and speed 45.
One upgrade I have made that I will share on Thingiverse is my damper feet using stress balls cut in half, mounted in a foot to fit the aluminium frame, absorbs nearly all the acceleration energy? They are magic!
The outer wall finish is very good and now printing in just north of 9 hours, 46% reduction in time with very little if any reduction in strength!
Just thought it was worth sharing, maybe you could make a video on this.
