I bought a Form1 used a couple of months ago, which i was told was malfunctioning. Well, it was, the Y-galvo gain potentiometer was WAY off and everything came out at 200% scale on the y-axis. I have fixed the issue, but i am now facing another problem, which was clouded by the Y-axis scale issue.
So, it seems that the further i put my prints to the edges on the Y-axis, the more skewed/tilted they become, like a paralellogram. When printing in the middle of the build plate, there is no issues, but if the print is big and wide enough i expect that this will become a serious issue and everything will come out as a reversed trapez.
I have printed 2 straight pillars at the 2 edges og the Y-axis, to test and prove this phenomenon. As seen below, they both are skewed/tilted away from the middle of the build plate.
Is this something that anyone else has experience with? What can i do about it? Will i need to do something about the software or maybe the hardware? More Y-galvo potentiometer calibration?
