Bed Weight and Lifting Capacity
- Motors advertised at 84 oz in or 5.25 in lb
- with 1/2 diameter pulley, that is about 20 lb driver force - about right.
- Total lift is 40 lb from both sides
- Weight of bed - 7.5 lb for top and bottom, 3.5 lb for sides. Rods - .7 lb per foot, we have 3 feet - 2 lb more. Insulation - maybe 1.4 lb / cu ft [1]. We have 1/6 cubic foot, so only a quarter pounder of fluff.
- Bed volume of 1440 cu in, is 25 lb of max plastic mass that can be printed.
- Thus, if steppers can hold 25 additional lb, that would suffice for any print whatsoever. Let's test. See D3D v20.04 Data Collection.
