This is the one I used for my Shapeoko3 XL. I expect you will need to resize it slightly but that is easy enough to do. Just select the outer square and choose the correct dimensions for yours. Also note that this project has a bottom left zero location and not center so adjust that if you want to zero set to center.
Also check the bit since mine is a custom tool and yours may be different so go into the toolpaths tab and edit the toolpath to reflect your bit. Also check the final depth since I probably took more than I needed to this time. I will decrease it next time.
I don’t like pocket to surface faces, mostly because the initial engagement is not the cleanest.
I don’t even like the F360 face toolpath as it only allows climb/rapid (one-way) or climb/conventional (both-ways). Ideally you would surface climb/climb : first one edge and then back along the opposite edge… Just like Joe Pie does manually on his YT channel.
Are any of those option possible on Carbide Create though? I don’t see options to change the pathing for a surface job like that. I have never been fond of the initial engagement either but as far as I knew there was no other option with the software I have. I know the F360 is free for hobbyists and I assume I would qualify as such but have not moved into that software yet since Carbide Create has met my needs so far. I guess I can’t say that completely but at least mostly. I have needed Inkscape and GIMP to complete a few jobs as well but those are tools i mostly know already and are also free.
