Spindle Speed control from BOXZY interface
My primary material that I am milling is aluminium, which the BOXZY, as configured, really isn’t good for. Milling passes on AL with a 1/4” end mill should be performed at around 3000rpm, but the Makita variable speed router settings only allow for low-end speed of 9470rpm, leading to inferior quality facing, tool chatter, and dramatically lower tool life expectancies. To get around this issue, I am looking into PWM style router speed controls and would love to go ahead and incorporate this control into the UI control so that it responds to the gcode for spindle speed generate in post-process. Has anyone tried this and, if so, what is the best way to wire it into the system (ie directly through the Arduino board or as some sort of stand-alone component)? Thanks!
Is this a good question?
