attached is the .stl I want to carve and this is the project. Easel - candle sand bowl
I dont understand how this can carve the bowl do I use all the cut out style? I need a workflow or some sort of plan. like carve x first, use this cut style first etc. Really don’t know what to do in the steps to take. kind of lost as to where to start in the physical side of things
I have a 3 axis cnc
You need to learn how to do a double sided carve.
First you have to figure out if you are going to cut the top side first. (depending on the bowl design) Then figure out how to hold the workpiece down, with full regard to holding down the second side carve. Then you need to resolve how to register the piece when you flip it over, Once you have that understood, then it is time to use Easel magic to place the work in the material & how big/thick to make the bowl. Once you understand those things then it is time to turn on the machine.
going to cut the underside first to get the flat of the bowl. then put the bowl up side up and glue the underside to double sided tape on my cnc table and make the zero to be the centre of the bowl. Please explain easel magic
I find that explanation less relevant than I need. if I make the block of wood exactly in position when top or flipped to bottom then the same zero will apply. because I am carving the bottom first then all I need do is position the zero to the middle again and its centred?
It is very difficult to align a part by measurement. Much better to use at least 2 reference surfaces. Some of us use pins, or a fence to reference the part, some of us go by guess & by golly and do a lot of sanding. If your bowl base is small you will have to make light cuts on the top so the work stays put. Good luck,
Make a box frame to hold a square of wood and hold that down with good double- sided tape. Then square up your wood blank to fit. Double side tape that face down and carve the back of bowl. Then pry off the blank and flip it over and fasten that down somehow. If the center of the bowl is x0y0, then you should be OK. This is theoretical. Practice all safety rules. Maybe make the blank a little taller than the end result.
This kind of thing..I had to change colors to wrap around what I was trying to show. Making a fixture to hold your work is the key. There are no shortcuts to complex parts. You may need multiple toolpaths to do what you want to do. top carve, back carve,swoop carve, and decorative carves as their own files might be helpful. Once you get that done, then repeating for multiples is pretty easy, which is where cnc is great. I don’t have Easel pro so I can’t save your version.
Thank you Martin. I was told to use the 3d carving method with easel with this as my project. Easel - candle sand bowl
Doesnt this go against what to you suggest? I get the 2 job way but I also have to allow for a cove bit and a bit of an undercut so I’m not sure how that works too
If that is a ceramic bowl as an example, it may have been slab built or slip cast. You can probably get a bowl routed with a round nose bit…I’ve never tried any undercut and don’t know if the software can even produce g code for that. Worst case scenario, you get a hogged out bowl with no undercut I guess.
If software does allow it, this kind of bit might allow you to get it.

I have that bit so ill trial and error
its a resin bowl from a mold
