Build
- For the bed, because bed holder carriage nut catchers are printed upside down, best way to smooth is using a longer bolt to suck in a nut to clear the excess plastic. Possibly a different production engineering (machine redesign or part redesign) can solve the dirty nut holes
Bed Lift Capacity
- Bed itself is about 24 lb:
- 17x17" -1/16" plate
- 9' of 2x1/16" strip = all of 1/16" is 10 lb
- one 1/8"x18"x18" plate = 11.4 lb
- Rods - 2 lb (8' of 8 mm)
- Insulation - at most 0.5 lb from D3D_v20.04_Calculations
- 6x6" plates of 1/8" steel are 1.3 lb each
- How many can we lift?
- It should be, based on former results - 14 lb based on D3D_v20.04_Data_Collection#Bed_Weight_Holding_Capacity because we have 2x the motors, 2x the weight, and excess hold was 7 lb, so with double motors this should go to 14.
- Data:
- 4 plates (5 lb)
- 6 plates (8 lb)
- 8 plates (11 lb)
- 10 plates (13 lb)
- 12 plates (16 lb)
- 14 plates (18 lb)
- 16 plates (20 lb)
Run
- RAMPS 1.4 doesn't handle 2+2 series+parallel z motors. It is fine to drive 2 in series - bed lifts. Adding the other side just causes skipped steps.
