I’d like to see the file you’re attempting to cut, to confirm what you mean by ‘make shortcut at the end’. I’m assuming that’s what you’re saying about the weird top corner notch in first photo, but I want to make sure!
I did check them. They are not happening.
I did cut this like 5-6 times in a row, every on different place on my working area. They exactly same, with same mistakes in same places. Laser behave exactly same.
not easy to say without seeing, listening machine in action
Do you think you could record that file is sent being engraved in video and upload to youtube or something and share link.
I am more inclined to suggest is more mechanical than a controller. But you need to start cutting variables down.
Example could be, does the same issue happen if you reduce speed by 70% (and consequently power too)
And/OR, if you double speed, does it get WORSE?
okay, i did some tests.
I will record proper video on the upcoming days but for now i have some tests.
i was changing a bit power and much speed, please see photos.
on the attempts we can see that since i was turning up speed it started moving more outside, and at the end even when i went back to low speed 300mm/m i still was same bad shape.
Unfortunatelny i forgot to change laser power on last attempt so it went through material and couse some damage on forth attempt. But it doesnt matter i belive.
Just to clarify before my machine started doing this i change tension on X belt. ( I thought it was too loose, so i put some tension. Machine was working good but for some time it started doing this.)
What tension should i use, now its more like a guitar string it does even not loud noise when you pull.
I havent try to move that tension back as it was, becouse i just remind about it, and im already at home.
I will do it maybe tomorrow.
Let me know what you thinking.
dificult to tell without knowing your setup
However seems clear that your machine is losing steps when doing the rapids
And the faster you go the more extreme this shift is
Thank you. I will go through that tension on X axis and let you know how is it going.
However if it will not help I will provide all my machine detail with movie.
But I still wonder if so my X axis losing steps why it always happens in same spots .
