CNC Fabric Cutterhead Prototyping: More Speed (Less Torque)

In a previous installment, I used a 900-rpm gearmotor in my reciprocating-blade prototype and it didn’t have the speed needed to cut fabric sitting on a styrofoam spoilboard. The only place I could find to order a higher-speed version was AliExpress, and it took a while to arrive.

Quickly swapped into the same prototype cutterhead, with predictable results: It has a higher no-load speed but bogs down in the cut. This style of gearmotor won’t be my solution.
