Description
For use in the Formbot Raptor and Raptor 2, T-REX 2, 2+, 3 or other 3D printers with removable stepper drivers. We have tested these thoroughly on the X and Y axis on the Formbot machines with great results!
For the Raptor, you will need at least 2 pieces (up to 4). For the T-REX, at least 3 (up to 6)
NOTE: Firmware changes are needed!
