Hi Chelsea! Yes, it’s just the x-axis. The y-axis is working just fine. Here’s an extreme case with scoring lines (usually not this bad, but off in some places). Those squares should be aligned. NOTE: In this picture the squares do not like they are stretched in the x-direction, this is because this picture comes from an attempt to scale the file horizontally so that it would print correctly, but for some reason when scaling it down skinnier it became WAY too skinny.
And here’s cutting. This piece should be symmterical, but is stretched so that if I flip it, it won’t fit in. This is happening consistently, so a piece that should by 13.5 cm x 13.5 cm is coming out 14.3 cm x 13.5. I tried scaling the file horizontally by a percent that should correct it, and then instead of coming down to 13.5 cm it becomes much narrower, 12.6 cm. (This is what the first picture shows). Very wonky.
These cuts were done all day Sunday between 10:00 gmt +1 and around 21:00 gmt +1, and also Monday morning. There were no successful cuts on either of these days.
Sunday morning I had bad cuts and the laser head was not moving smoothly on the rails. It would tense up as I pushed it and then jump to a comfortable position and tense up again, in a pulsating kind of manner as I slid it back and forth. When I removed the belt it slid very freely, and all wheels turn freely. I reduced tension on the belt and got it to move freely, and did many pieces before I discovered the stretching effect. I adjusted the tension again and again, from very loose to so tight it began to feel like it was about start the too-tight pulsating effect. None of the tension settings made a difference.
I also squared up the laser arm, many times, and I’m 99% sure that it is as square as it can be.
Thanks for taking a look!
