| STEPCRAFT V2 Improvements |
|---|
| The frame build and rigidity of the machine has been improved. The aluminium uprights are thicker, the ball screw spindles are thicker, there are now 4 brass rollers on each drive system, The X axis bridge has been increased in cross section. |
| Each brass roller bearing and shim combination are individually fitted at STEPCRAFT prior to packing into the machine kits. This results in a play free system out of the box with minimal tweaking |
| The machine is now powered by 30V DC as opposed to 19V DC. The drive torque/power of a stepper motor is strongly related to the applied drive voltage. As such the speed the machine can run as is greatly improved. The rapid stable feed rate of a well tuned STEPCRAFT 840 machine is 3000mm/min. |
| The cable management is now “through” the machine frame and under the machine instead of towards the back of the machine in a plastic pipe |
