I’m dusting off a couple of year old Ortur engraver that I havn’tt used in a while and have loaded 1.0.06 Lightburn software (that’s all my license allows) on a PC. After a new software install I’m simply trying to print a single letter, ‘H’ on a piece of wood to try it out using absolute coords. I don’t have any problem doing that but when I repeat the print simply by pushing play again, it will print 1mm to the right. If I keep pressing play, I will get the same result with a lot of H’s printed at 1mm intervals. Each print seems to return the head to 1mm to the right of the last origin and set the origin to that point.
It’s time for a deep cleaning and adjustment of all the mechanical bits, because that puppy seems pretty well gummed up.
Although this guide is written for Sculpfun machines, it’ll give you some ideas of where the skeletons are hidden and how to smooth things out, because all diode laser machines have much the same structure:
If it has rubber rollers, they may have nasty flat spots from sitting too long in the dark. If so, you may need a few replacement parts.
When you get it back together, scale this test pattern to fit the platform and run it as fast as it will go in Line mode with optimizations turned off and power set to mark cardboard:
Thanks for the advice but the machine is not binding. I get the exact same offset each time I hit the play button no matter how many times I repeat it. If there is binding I should see some sign of it when I print a larger object like a large circle. A large object prints fine with no distortion. Simply put, the head will return to the original origin plus 1mm on the x axis when done printing.
