Other useful 2D toolpaths
2D adaptive clearing : For removing spare material
2D Pocket : For recesses with flat bases
Trace or Engrave : For engraving patterns or text on a surface
== 3D Milling ==
[[File:3dclearing.png|thumb|400px|right|"3D Adaptive Clearing" is good for complex 3D shapes]]
From '3D Milling' menu, select 'Adaptive Clearing'.

From '2D Milling' menu select '2D Chamfer'
Line 241 ⟶ 322:
* (If you're using a superglue mount, start this first to allow 20 - 30 minutes to set)
* Turn on the Boxford and its monitor.
* [[Tools/compressor#Using_the_Air_Compressor|Setup the air compressor]] and get it charging.
*
* Check the Boxford is reasonably clean. The bed and spindle must be spotless.
* Login to Windows, start Fusion 360 and CNC.js.
Line 269 ⟶ 351:
'''Manual movement'''
Set a movement rate in the 'Move' box. This is the value (in mm) that each axis will move for one keystroke, tap the keys, DO NOT HOLD THEM DOWN.
* Left / Right Arrows move X Axis
Line 284 ⟶ 366:
# Right-click the toolpath and click 'Post Process'
# In the pop-up window set:
## 'Post' to 'Boxford
# Hit 'Post'
# Save .nc the file somewhere - probably to a folder with your name.
Line 303 ⟶ 385:
* Click the 'Play' button (again).
** Check that you've loaded the correct tool and set the z-height (again).
** Watch it like a hawk with your hand over the E-stop if this is the first time you've used this .nc file. Second and subsequent runs you must remain next to the boxford but don't have to watch it constantly
** Press OK.
Line 309 ⟶ 391:
'''Running an air pass'''
* Set the machine to move to a known Z height clear of the workpiece, record/remember this height.
* Set the Z height value to zero
* Run the job and watch to check it runs as expected
