Bringing this topic into it’s own thread as it may benefit others who working with plastics and metals.
What I know so far:
1F uses the Buildbotics open-source controller which does not support ARCs. ARCs are converted to line segments by the controller, which obviously have a “resolution” as opposed to a true curved tool path. Short of changing controller, 1F has no realistic avenue to address this other than hope for Buildbotics to include ARC support in a future firmware release.
In the Settings screen, The Max-Deviation number dictates the allowed deviation from the true path the controller is allowed to make when converting ARCs to line segments. My machine was set to 0.05 out of the box.
Below are some tests I’m doing to find the ideal settings for my needs. I cut plastics so will be interesting to see how these numbers look in metals which will likely be more demanding.
4" Diameter ARC on XY Axis:
My “Benchy” for testing ARCs on Z axis:
I’m currently testing ARCs on all axis, so far the results don’t seem to be as predictable as the above tests. I’ll post some pics later on.
I’m sure there are other ways to work around this limitation. I’d be curious to find an ARC-to-Lines software that could possibly provide more control over the conversion.
Please share your results and settings you’ve found to work best for you.
