I am trying to burn an image on a rather big drum shaped item. If I just burn “outline” only, it comes out perfect. If I try to burn “fill”, I see a double images misaligned. If everything was perfectly square and round, I wouldn’t have this issue but that is not the case given the size of the drum. I can see that the second pass created a great image but not aligned with the first one. Please note that I am only using a single pass and all default settings including the pass optimization.
Is there a setting that would force the app to use a single pass? I suspect this is something to do with optimization settings.
yes i am using the rotary. Most likely it is caused by a slippage and the object being not 100% perfect. That’s why I am trying to figure out away to burn it in a single pass. Why does it make a multiple passes when I set it to only a single pass? Is there a way so that it won’t come back to burn the same image again? In other words, is there a way to instruct the laser to burn from top to bottom gradually in a single pass instead of moving around? Thanks
1200/80. I guess I cannot simply configure it so that it will burn top to bottom in a single pass without going back up later. I know at about 50% progress, the image is very good and I can manually stop… that would be a hacky way to overcome this issue… thanks for your help.
I also found out there is an advance setting to configure 1) fill shape individually 2) configure the line speed to 1000 (it defaults to a much higher speed). In the end , I only used fill and chose fill shape individually. That worked.
With this minimal amount of movement there is less chance of ‘slippage’.
If I scan it up/down the cup is rotated one way then abruptly rotated back the other direction.
All of the movements can be modified by the acceleration settings of the controller. I have all of my Y axes, acceleration, start speeds and max speeds changed for rotary use.
Here you go! It is much bigger than tumblers and mugs that I did in the past. My coworker just adopted a Saint Bernard so I thought I would give her a set of big bowls as a gift. In the end, it worked out (good enough). It is about 8inch wide. On the back of the bow, there are more stuff engraved like personal messages.
I put my finger inside the bowl to press it down to create some friction. I am sure I can make some stuff to hold it down with an adjustable tensioner (something like the leg that the blue arrow points to. However, I don’t think I will do something this big that often. I don’t mind using this manual method. This is to prevent any possible skipping.
The following setting was super helpful so that the head doesn’t move back and forth.
I removed the line and chose only fill.
Again, this is only when you work on a large span of a drum. For a regular size mug and tumblers, a small error is acceptable as it won’t be magnified.
cute dog and nice bowl.
