Autodesk software always could make a price-jump. I prefer learning one software that will be my toolchain for years - so no Autodesk!
+jay polo g2core is in competition to grbl? never heared about it, thx!
@Michael_Weber Yes, same concept, but potentially more advanced capabilities. And running on an Arduino with a 32bit ARM processor at 80Mhz. https://github.com/synthetos/g2
@Michael_Weber Got it, thanks. It could always happen. But it seems the world is moving towards their current model rather than away from it. It feels worth the risk to me that I might have to change products in the future.
Just figured out CutViewer Mill isn’t as good as I thought. Couldn’t finish my example g-code. So I stumbled around and found CAMotics - which is a really nice tool to review your toolpath 
I do highly recommend to have your eyes on this beautiful piece of software!
@Michael_Weber ah i see. I didn’t realize that. I mostly mill or laser pcb’s. For that i use a plugin called pcb2gcode.
@Jay_Polo No. I accually never heard of it before. But i mostly use my cnc with a laser nowadays. So i’m only using 2 axis at the moment.
I made a simple protoboard controller for that with an arduino nano and 2 stepper controller.
That’s only 2D. What am I going to do is called 2.5D,as there needs to be a lot of height information. But it seems CamBam can handle it - even if it crashes a lot of times…
Damn it…when opening a file I just had to select ‘standard g-code’ instead of the default ‘fanuc’ - which is limited by design to 80k lines. Now CutView Mill and CAMotics work fine 
It’s never bad to have a backup application
@Mano_Biletsky_Open_M I believe g2core is the next generation of TinyG, but can be deployed on an ARM Arduino Due. Have not yet tried it. I keep finding things like this to ‘upgrade’ before I even have everything fully working on my existing machine. Focus, focus…
@Jay_Polo yeah i do that too. Suddenly you’re realizing that you are designing a production ready thing, while you still ain’t got a prototype to begin with😆
@Jay_Polo project hasn’t had any updates for months. I think the developers are looking to do other things.
