I use Alibre and am very happy with it.
They had some hard years when they were bought by 3DS, but now they are back under the old management and development is continuing.
I recommend it.

IMHO, the geometry should be as close as possible to the original drawings without dummy items. In this way you can update one primitive and all the MOPs will be automagically updated
You can always write a plugin or script to do what you would like. One of the big advantages of CB.

You can probably find parameters to cut without breaking the tool, but if your machine is not stiff and you cut hard material
you need to expect that the resulting dimensions will need tweeking until they are right.
Circles may not be round etc.
That is from the flexing of the machine, more in certain directions, less in others.

Hi Mark,
Please think about what a pocket does.
A pocket clears an area _inside_ a shape.
If there are islands that area is not cut, but the pocket does not cut outside the shape, that is how it is defined.
There is one little possibility, but I don't know if it will help in your case.
That is the roughing clearance which can be negative causing the shape to be cut larger.
I would suggest, however, that using an offset from the shape is the best way to work.

Adding many special cases to commands to do things that can be done simply with a little planning with existing
commands is not the best way to keep a program simple, clean and error free.
I hope that CB will become your work horse as it is mine, it just works.

It sounds to me like the simplest way would be to make text files of the output of each of your scripts and to then include them using the NC MOP.

Hi Mark,
I would second the suggestion to do roughing and then a finishing pass with reduced tool engagement and speed.
3mm Tools are very flexible and the cutting data from the manufacturer only tells you at which speeds the tool doesn't break, it has nothing to do with cutting accuracy.
Also be sure that you have minimal stick-out of the tool from your collet to reduce the tool flexing.
To reduce machine flexing your only possibilities are reducing the speed and the tool engagement.

Also remember that your tool and/or machine is flexing as force is being applied to cut the piece.
How much flexure you get depends on the stiffnes of your machine and tool.
The flex is usually away from the cut, but sometimes tools pull themselves into the work.
Conventional or climb milling makes a differrence too.
These are things you will have to work out yourself as they depend on the geometry of your pieces and the aggressiveness of your cuts.
Are you slotting to cut out the pieces? Then it can be difficult to imagine how the machine is flexing, but probably against the direction of motion.
You most likely will not see these effects on your laser cutter as it only has to overcome it's own inertia without flexing.
Have fun!

Have you seen any issues since it's a development version?

I have been using it successfully for the last couple of months, but that is only my experience.

Please post the .cb file.
It shows us what you did, what might need to be changed.
The nc file only shows the results.
Best, Don

Hi Kerv,
This is a known bug in V0.9.
It has been corrected in V1.0
I would suggest that you go to V1.0
Best,
Don

Does a new license have to be purchased for this?
No, your old license will work, but you need to copy the license file to the V1.0 installation.

This is a small size engraving with only one depth to engrave to.
Do I understand correctly that you are doing this with a 3D MOP from a mesh?
If there is really only one depth there is no reason for that.
Use the outline to make a pocket or profile.  It will be much quicker to machine, cleaner and you will not be stressing your memory limits.

Here in Switzerland Haas has a bad reputation, but both shops that I know that have them are happy with them.
I don't know more 'though.

I WILL consider putting it on there, though, only so if a design needs 'tweaking' after a trial run, it would be readily available.

That is the only reason I installed CamBam on the machine computer.
