Carbide Create sets Z=0 during moves, drags on piece?


(Steve Drevik) #1

I love CC over Makercam, but my first use of it I’m perplexed by one thing.

Looking in the gcode, whenever the bit has to move across the piece, it sets Z=0 (instead of raising it ABOVE the piece by a reasonable clearance) before moving to the new X,Y. If I’m not perfectly level, this can drag the bit across the piece, scarring my work.

Other than manually search/replacing on the gcode file, I can’t find a setting in Carbide Create to set the ‘raise above piece Xmm when moving’ setting.

Anyone else had this problem?

Example Gcode:
X76.382Y19.697 - cutting
X76.430Y19.896 - cutting
X76.450Y20.093 -cutting
G0Z0.000 - raise to top of piece
G0X108.111Y21.435 -big move, drag spinning router bit across top of piece = scar if not level and Z=0 is really a little above the piece.
G0
G1Z-0.211F64.1 -drop before next cutting cycle

Please see:

Job Setup | Machine | Retract height

Defaults to 10mm, but is easily accidentally changed.

Duh, forgot about the job setup page. I feel dumb now. Thanks!

Don’t feel bad — this comes up pretty often — the change in terminology (it’s usually termed “Safety height”) may contribute to the confusion.

Actually, I’d say if they made the default 5mm (like MakerCam), it would never come up in most cases. A default of 0.0 is just strange.

Default should be 10.00mm — if you get something else from a new, blank document let us know and we’ll look into it.

Pre version 313 I would have this happen if I opened an existing drawing, cleared it (using the default setup page which was set at 10mm), and created a new drawing and output the g code. I discovered this by dragging a 1/4" end mill across some very expensive maple. I was able to recreate this several times. I just always close Carbide Create and start a new drawing that way. Not sure if the new version does this I haven’t tried it yet.

I just tried it in Build 313:

  • Opened Carbide Create
  • went in to Job Setup
  • hit “Clear Drawing”
  • Yes
  • Ok

and Retract Height is still set to 10.00 mm
