Stepper Drivers
- DRV 8825 is used for more current on Z. [1]
- Initially, one side motor on Z was 44 mm long (17PM-K402-P4V Minebea Motor Mfg Corp, V and A not shown), and the other was 48 mm long (17PM-K402-P5VS, 3.9V 1.3A). *Small motor was easy to stop - pound or 2, whereas larger motor was more like 10lb to stop.
Heating Time
- Extruder - at 11C from 11C to 230C - 2:15
- Bed - 2:47 at 11C from 11C-100C, 20C hysteresis at top
Physical
- Print volume - 12x12x10 inches - 1440 cu in - or 24 lb max weight of print.
Bed Weight Holding Capacity
- From D3D v20.04 Calculations, bed is 13.5 lb, and we should be able to lift a total of 40 lb withe the stepper motors - so an additional 25 lb.
- Weight of 1/8" steel plate, 8x8" - 2.3 lb. 10 or 11 of these should be held up.
