@dell-vos no problems for software etc. Take care about cables

If I can add my experience with coreldraw, check the x and y size after the export. Coreldraw, often, isn't correct during export, and you must use "tricks" like defining a page size equal to the object and export with "selected objects only" unchecked. Btw, maybe, also, you have unchecked this, and the page size is larger than the objects, so you export a bigger image... Like others designing tools, there is a lot of parameters influencing export

@intruder but did you replace the Nano?

@doggindave invert x axis in your software

@Zax if I remember, I've sent you one file, but it seems that coreldraw uses some dxf parameters not supported. But plt works fine 😉

Unfortunately coreldraw does not export correctly in dxf (quite unreadable in t2laser or autocad tools, needs modifications), but the output in plt is perfect for t2laser.
And, yes @zax, you're correct, there is an option for infill, if needed

@Nicholas-Buttle you can put an image, but I think it is a small adapter used to test the laser without the control board, in case of malfunctioning

@gman machine? Software?

@firewirehn I don't know if you bought the license, but the trial version of t2laser has a limit on the number of g-code lines. Maybe this explains the stop at the same job percentage

@mattyman41 probably you have a (near) defective laser fan. Do a search for noisy fan in this forum
