Reach & Payload
Work Envelope
380mm × 380mm
Height × diameter, no tool offset
3D printed payload
~1.4 kg (~3 lbs)
See additional note below
Machined payload
~3.6kg (~8 lbs)
The 3D printed version starts seeing noticeable flex starting around 3 lbs. The motors have ample torque beyond this — the limit is rigidity, not power. Machined parts significantly increase the realistic payload ceiling.
