Plenty of people call themselves speed printers but few of them will forget to set run_current and under-amp their steppers for nearly a year before noticing that their accels are probably lower than they should be…
Upping my currents from 0.8 to 1.1A has more than doubled my max accels.
I only toon 10 seconds of video but I happened to capture the exact moment it lost steps. You can see and hear it as it finishes the pedestal and starts on the legs.
2/2 #3dprinting #speedfox
I just flow rate tested ambrosia asa to 34mm^3/s; the fastest I’ve ever gotten on this machine ( 
+rapido2+clockwork2)
There are a few of us who print these #speedfox models from time to time as an alternative to #speedboatrace. So it’s time for another submission.
I call her “What Lost Steps?”

My new Trident is nearly fully built and I couldn’t resist printing a #SpeedFox
- KVP Stellar Blue ABS
- Lightning Infill
- 22m 33s
That’s a lot faster than the 1h 12m I got with my PETG fox on my Prusa. This run basically pegged my extruder at 26VF the whole time. I might have a little more left in it but I didn’t want to push it *too* hard.

How to print a #SpeedFox Model: https://www.printables.com/model/553732-cute-dancing-fox-low-polysupportless Rules: 1. There are currently separate categories for PLA, PETG, ABS (or ASA). 2. 0.4mm nozzle, 0.4EW everywhere except infill, where you can go as high as 0.72 (but not higher). 3. 0.2mm layer height, 0.2mm first layer. 4. 15% infill (any kind you like). 5. All perimeters should be 0.8mm. That means four layers top and bottom, two perimeters. #3DPrinting @[email protected]
