@_r pure python are more version independent but all the ones with a core written in C seem to be quite picky, and most of the important ones are. Numpy, Scipy, Matplotlib, PyClipper etc
all my Add-Ins that needed compiled dependencies are deprecated. I try to avoid them when possible but it is just frustrating spending days re-implementing something a simple import would fix
Trying to use compiled python packages with the #Fusion360API is miserable. there is no official way to actually do so. It basically boils down to either shipping the right version bundled with your Add-In and then scrambling to ship a fix when the fusion internal python version inevitably gets updated with zero warning, or pip installing it at runtime
The y axis is only 160mm long. Even with an extremely narrow toolhead (which is of course entirely missing from the design with seemingly no provisions for it) would reduce it to 100-120mm of travel. Depending on the guide plane distance most of that is lost for taper cutting, likely leaving only 5cm of working area with any taper cutting at all, and maybe 10cm with straight wire

These gantry XY connectors unsuited and unmanufactureable. It isn’t clear if the are meant to be metal, in which case they are unmachineable, or plastic in which case they are extremely thin (0.9mm walls) with only 1.9mm holding the 10mm round rails on, printed threads in every orientation, and no clear print orientation.

With the 2.6k price tag they could technically afford to SLM metal 3D print them, but o do not think that is realistic or practical

There are major flaws on the shafts connecting the belt pulleys to the motors. Components placed inside each other, flanges rubbing on printed parts, finger couplings being made to take up axial and radial loads, belts being made to take up axial loads…
Like literally just stainless LM10LUU on (maybe?) stainless round rails right under and around the cutting zone where all the EDM swarf lands on

There are so many bearings submerged that are in no way rated for it…
With lots and lots of abrasive metal oxide dust suspended in the water…

I see no problem there at all /s

The new CAD files RackRobotics released about the supposedly soon to ship Betta Wire are a bad late April fools joke. None of this stuff looks anywhere close to ready
G-Code output looks good
