Hey everyone I have an issue with my Y-axis only on designs over about 15cm. When I frame the design it goes around the whole space. When I start it however, it goes loud and fast and only a few cm down and starts from there. I can do 10 cm designs and its no problem. The finished product is the exact size it should be. Ive adjusted the belts but seems fine and all 10cm projects are exact size they should be in end product. Its only the larger designs Im getting this error. Any other ideas or what Im overlooking?
So in the video you can see the frame first and the start would be at the bottom. This time it moved further down then last time but still not all the way where it should be. In the photo you can see where it moved down too last time.
Also the noise from when laser is hitting it only occurs on this for some reason. The same noise doesnt occur when Im doing smaller items.
So the part it starts cutting is the bottom of the design. thats wayyyy at the bottom where you see the bottom of the frame go. it only goes a little bit down and this time started printing maybe halfway as far as it should.
I don’t know what to advise you on this. It seems like the controller would be doing this.
Do you ‘send’ it to controller and run it from there or do it all from within Lightburn…
When you re-run it, do you just push ‘start’ … I’m trying to find something that is a common area to cause this. I haven’t seen what you describe and can’t relate it to anything I know of…
Maybe @LightBurn has a clue to look for or a suggestion.
How did it work before if it was a configuration issue?
You can mark it solved (upper right). Please specify what the ‘solution’ was for others, if possible. What setting did you change from what to what?
It’s also nice to know if it’s a new item and it has never worked properly or if you’ve been using it for a year then it fails… Different trouble shooting steps for different issues…
This is very helpful for people trying to solve their own similar issues.
Its newish lol. I havent done anything large and noticed it only on that larger design. Everything smaller is fine.
I figured it was moving too fast at the start and skipping the belt. Under vendor settings on y axis it was default 10,000 max acceleration. I set it to 4,000 and adjusted the max speed from 500 to 400 as well. And that seemed to handle it. I will check the max speed and probably bring that back up in a bit but for now the acceleration was the issue.
