heyi looked in the bom and i saw that the v2 of the control pcb contains 8 STEPPERS, while in the MOTORS section there is only 7 motors, what am i missing? ;

• 2x Nema 17; L=40mm; Holding torque: 39.22 N.cm
• 3x Nema 17; L=34mm; 5:1 mechanical reduction; Holding torque: 121.2 N.cm
• 2x Nema 17; L=34mm; Holding torque: 21.57 N.cm

 

• • 1x PCB

Hi Hotam,

You are right, the current design of Thor only uses 7 steppers, so 7 drivers are enough.
I designed the new board capable to control up to 8 steppers in order to be able to add another degree of freedom. (I was thinking to add rails on the base)

Hope it helps!
