Okay, that was what I thought. I read a post on another forum dated over a year ago that said the guy was doing Z moves during the program with a Ruida controller. He must have been hitting the buttons and not through the controller.
I wonder if anyone has ever made a curve profile and used a pair of micro switches to move the Z as the gantry moves?
Yeah, and they are not cheap. I was thinking more of a profile the switches below the gantry would follow. Mechanical micro switches would probably have too much ‘gap’ between make and break. I know some of the equipment I work on use a photo make or break sensor, but I’ve never really looked very deeply into their operation. Don’t know if it could be done with one profile, or if it wold take one for each direction up and down.
The things I’m looking at would be pretty flat in X, but have a curve in Y so the engraving scan movement wouldn’t be a problem. The center 3/4 doesn’t have a lot of curve, but the top and bottom edges may have a bit more than a long focal length lens could handle. It’s one of those ideas that if I have the spare time in the next decade or so…
LightBurn will let you split a job into slices, so you could just make several shapes, pick a “range” of Z where the beam will be in focus, and set the Z offset for that range appropriately. If you assume that the focus has a valid range of +/- a couple mm, you could probably figure out how big to make each “slice” of the engraving and do it in sections like that.
Yeah, I could see that for text, not so sure how that wold work for logo or graphics. Kinda funny, Ruida advertises the 6445G as a 4 axis controller, but it will only do X and Y at the same time. If they incorporated a way to map the Z via the pen to create a profile they would be in high demand.
I don’t understand the question. Print and Cut is a way to rotate / size / position your output to match an existing cut. It has nothing to do with whether the machine can control the Z on the fly.
Ahhhhh, that’s the piece of the puzzle I missed some where. I just break it into sections, and tell LightBurn to move the Z. I will have to play with that. I just downloaded the trial so I’ll have to hunt for that setting.
