Haven’t wanted to use my Longmill for cuts I’ve used in the past. Thought I’d fire up and try a new approach to my outdoor chair components. Cutting my components from 2 inch moist material from a file I’ve used my times. The file is from Carbide Create Pro, saved to gcode and launched with gSender. 1st component successful, .187 dept per pass, 35 plunge rate, 70 ipm, total depth 1.5", 8 minutes of cut time. 2nd component (only difference is 80 ipm) get approx 3/4" in depth halfway down one side and plunges north to Alaska shutting down the router. I raise the Z and select jog to XY zero, it’s way off. Rotate the model in the gSender workspace to see if there is there is a path for the plunge, nothing on screen.
I hesitate to voice a theory, but I’m wondering if a Longmill Mk2 (with a Makita for a spindle) and a sharp bit can and does run off into the woods when the step motors experience to much stress? Personally I didn’t graduate from University in Engineering with a minor in gcode to be able to decode the file where this took place. And honestly my survival instincts tell me the gcode is not the problem because the first component was successful.
I’m going to post this on the Sienci Forum as well and in the end I’m going to accept if this machine should only be used for light topical carving and not for cutting deep components even and slow/er speeds. Image attached.
