Hi all, first time post here. I’m hoping someone with more experience can help me out. I have only been using my K40 for 2 weeks. There’s an issue that I can’t seem to get to the bottom of.
When I perform a raster engrave over a large area (approx 150mm), the verticle lines are wavy. However, if I perfrom the same raster engrave over a smaller area (approx 50mm), the verticle lines are straight.
From reading other posts, I have tried the following with no luck.
- tightening the X-axis belts
- loosening the X-axis belts
- ensured the lens holder is tight
- mirror alignment is good (parallel, and quite accurate)
- don’t feel any “kinks” when manually moving the x-axis
- tried different speeds
Here are some test and photos I have performed:
grid test - vector engrave - lines are straight
cirlce test - vector engrave - circles are good, all joins up
grid test - raster engrace - speed 100mm/s vs 300mm/s - verticle lines wavy
scanline test - looks ok to me
tried on two laptops
svg file - 10mm x 10 mm squares, lines 0.5mm thick
Any ideas? help is much appreciated. Thanks.
