Sorry if this is a repeat, spent the morning looking at all the rotary related posts and can not seem to find the specific issue I am having. I thought I read about this problem before purchasing and using my rotary.
I have a Mansfield Custom Rotary and have worked through the steps per rotation and wheel diameter. I perfected the settings by burning a 20x20mm square on a 2" dowel and measuring the output. All is well on that point.
I am having 2 issues, not sure if they are related. I am trying to repeat the problem so that I know what to avoid and not destroy more tumblers.
Either at the beginning or the end of the burn, the first few lines are missing (edge of a circle flattened out, a couple of letters missing from a small font). I thought this was because the controller though the table was at the end and could not spin more, so it just skipped those lines. So, I set the y axis in the middle of its range on the controller, and hit the origin button before starting the program. However, I still have had the problem intermittently. This leads me to believe the problem is elsewhere.
Another issue that has happened on the last couple of projects is an entire line is not engraved (vertical through the tumbler) . I can’t provide pictures, because I ran the program a second time and the engraving corrected, but the tumbler is still ruined because it is overburned… But it seems to me like the motor moved two steps when it was only supposed to move 1… or something to that effect.
I am enjoying lightburn and the support community. I am just wondering if someone has some insight into my problems and could point me in the right direction.
