For a 2 flute 1/4 bit try tool settings (images for reference only - do not use values in images):
- Spindle Speed: 10000 (set your router to this)
- Cutting feedrate: 30 in/min
- Lead In/Out: 20 in/min
- Ramp Feedrate: 13 in/min
Cutting operations → Passes (such as 2D Contour)
[TIP: for any text input in Fusion360 operations, make change, then right click and chose “Make default” to keep this setting for all future operations.]
- Use Multiple Depths
- Max Roughing Stepdown: 0.125 in (assume you are cutting 3/8 stock)
- Use Even Stepdown: Checked
Cutting operations → Heights:
- Clearance height: 0.125 in from Retract height
- Retract height: 0.125 in from Stock top
I assume you adjusted the z-axis and set zero depth.
If using the Ridgid 22002 router check that the z-axis adjustment arm has not popped out of the router body. This happened to me a number of times without any reported errors in GroundControl. This is a very weak link, and requires little force to pop out, so GroundControl will not register it as ‘end of extent’. Highly recommend doing Cheap z-axis fix if you have not already done so.
The router sleeve bolt should allow the router body to move freely in z-axis without wiggle in x/y axis. Many people find it easier to always keep the clamp open and adjust the adjusting nut.
In your screenshot you have ‘Bottom height’ set to -0.375 in from stock top. If you do not use “Multiple Depths” as mentioned above then this will be way too deep.
Questions:
- What thickness is the wood stock you are cutting?
- How many flutes does the bit have?
- Can you post sample Gcode as File upload or Preformatted text?
