Additive Subtractive Manufacturing By Layer

The ASMBL tool is a brushless DC motor driven spindle, controlled through a RC electronic speed controller. This is driven by the Duex5 board on a PWM pin established in the config.g and Fusion 360 post processor. The tool is attached to the Jubilee via a modified toolpost. A a 20mm vacuum line and vacuum is attached to the ASMBL for chip removal.

Milling/Engraving Workflow

The origin must be correctly placed on the top of the stock to mill/engrave prior to operation. This can be easily accomplished by jogging the tool to the desired location, raising the z height such that a piece of paper just barely gets caught under the milling bit, and then noting the x, y, and z offsets. These can then be placed into the current workspace offset with G10 L2 P1 X_offset Y_offset Z_offset. Once this has been accomplished a gcode cam path can be uploaded and started.

Tips

Make sure you are using a PWM compatible pin with the ESC controller
4S motors and ESCs can use 12V PSU, 6S motors and ESCs can use a 24V PSU
Make sure to "tie" the negative leads of both PSUs (if using multiple, like a 12V PSU for the ESC and a 24V for the printer) together and to ground in order to make sure that the signals are referenced to the same ground level
ESCs using BLHeli firmware are known to work
