Hello again. Again I’m in need of help with the setup of my K40. I’m amazed at how much I’ve been able to improve its quality. Unfortunately now I’m stuck.
The problem is the following. The path is almost perfect, sufficient in any case, but when cutting 3 mm methacrylate, the oblique cut on the piece is unequal. This is seen when I cut a circle. In the red area of the photo the cut is oblique to the outside. In the green zone it is obliquely interior (not as exaggerated as in the red zone) and in the other zones the cut is almost perpendicular.
The machine is leveled with a maximum error of 0.4º. The x-axis, the table, everything is leveled in the same way. The x-axis belt has the proper tension, I think. I have also been testing different focal points, with a difference of 7 mm in height. I don’t know what else to check.
Can someone give me some idea what else can I check?
Thanks to everyone.
