I would like to be able to print something, then turn it on it’s side, and the lidar executes a comparison of attempts, chooses the best. This can be applied to more than overhang, but you would just need a print that can be laid on the side with multiple comparisons.
I think it’s still basic enough as is, perhaps depth of lidar focus will need to be adjusted. Perhaps take multiple focal point records.
Thanks very much!
If you have to pull the print off the build plate, you can inspect the overhangs yourself by eye and choose the one that looks best for yourself.
While what you propose is probably doable, it’d be very complicated to implement and use, and it’d be a potential cause for damage to the machine. Small errors in the z-height of a print can bend the hot end, for example.
I don’t see BBL doing something like this.
It would actually be very easy. Set the model to a certain thickness, then lower z to just above that, analyze, change focus, analyze, do multiple times for each focal distance needed at each point, then move to the next point and repeat. What you’re proposing is that the toolhead crashes into the bed during lidar engagement? I don’t think I’ve ever seen it do that when it’s looking at the first layer.
I could look at it, but lidar will always do it more accurately and at a fraction of the speed.
It’s probably 50 lines of code to identify the best angle in the overhang example.
Once that is had, it’s just a task of changing the model/benchmark print, and making it from the sideways perspective the lidar will look at it with.
