Tool Starting Position - Fusion

[matt6]

Hey all,

Using Fusion 360 and the M3. I'm not sure where to position my tool before executing the G Code. Using the Fusion "Simulate" tool, there doesn't seem to be any consistency as to where the tool will be starting. I'd like to be able to zero (G92) at the top-right corner of my stock (which is currently set as the Stock Point) then just hit "Go" and have it make the cuts. Is that the default? If not, is that possible?

As long as the work zero location in Fusion (box point you select) matches where on the stock you pick to zero it will work. Don't sweat where it actually starts cutting that's irrelevant as long as the two WCS match.

Awesome, thanks aforww.

Did two cuts with no problem, everything came out exactly as intended. Started my third cut, ran well for about 5 seconds, then it looked like my stock was loose so I paused and re-secured the stock. Unplugged the M3 from my computer, then plugged it back in, exited and re-opened Universal G Code Sender, and re-homed the machine. Set my new zero (G92 X0 Y0 Z0) at the corner of the stock then bumped my router up 5 mm (as I had done the previous 3 cuts). Turned the router on and hit send, and the Tool dove into the stock and into the platform. Attached are screenshots of the executed G Code. Starts with the G92, then raising 5mm, then hitting Send. Any idea what I did wrong?

the Z is going down to -9mm and -13mm, not sure how thick your stock is but that is why it went through it.

Also, unless you are sure you are selecting the G54 system you need to delete that line from your G Code. Also, as berogers said, your code is sending it pretty deep. It is making a rapid plunge to 8.73mm deep, which is a big no-no.

Can you share your Fusion 360 file so we can look at your CAM setup?
