Load Cell, 100gm. Straight Bar, Gauge for leveling 3D printer bed.
about a year ago by Member #853360 verified purchaser
I purchased straight bar load cells in 100gm. 500gm and 5kg ranges. I'm doing model airplane stuff, and a pair
of 500gm cells is being turned into a force gauge for drag and thrust (just one axis) of an Electric Ducted Fan
(EDF) in a wind tunnel -- made from a Sonatube and the suction end of a floor drying blower. But the 100gm
cell is already successfully in use. I cut a U-shaped piece from aluminum strip, drilled & threaded holes to
mount the load cell at the bottom of the "U" with the cell extending up the middle of the "U". Then I attached a
short flat tongue of slightly thinner metal from the other end of the cell. So for bed leveling, the print head
contacts the tongue and I can get matching readings at four corners, and the bed is accurately level. Then
there's a separate final center-height adjustment, not using the load cell.
