Sarrus Linkage Mark III
by fdavies, published
This is the next step in my attempt to make a Sarrus linkage based 3D printer. The idea is to have a cartesian mechanism without those long rods and bearings.
I built three of the Mark III and mounted them in a x-y arrangement as shown. They can move over a square about 105 mm wide, and someday may carry an extruder. They are driven by DC motors taken from inkjet printers. These motors are driven in a servo arrangement using quadrature optical encoders and optical strips removed from the same printers.
2 end pieces
3 spine pieces
6 hinge plate type a
6 hinge plate type b
1 motor plate (modify to fit your motor)
1 belt plate
1 pulley plate
1 opto plate
1 DB9 bracket
Do a lot more stuff (details available upon request) like trimming, drilling out holes, etc.
Mount either a stepper motor with belt (not shown)
Make three of these things and connect them as shown.
