Inconsistent lines and curves
Hi,
I'm getting some inconsistencies with infill lines and perimeter lines, I'm also seeing some gaps as well. Any insight into these issues would be greatly appreciated.
RE: Inconsistent lines and curves
The circular problem is loose belts or drive gears. The layer one is partly belts, and partly improper Live-Z calibration.
Use this procedure to set the gears on X and Y, and verify the belts aren't sloppy loose.
Flat First: Drive gears must be tightened flat-first.
1) Start with both set screws fully loosened so the pulley is free to spin on the motor shaft.
2) Align one set screw dead center with the flat on the motor shaft, slowly tighten the screw until it fully contacts the flat surface.
3) Torque the flat set screw to spec.
4) Now tighten the jam set screw, and torque it to spec.
Once tightened, never touch the flat set screw unless the jam screw is first fully loosened.
Why Flat First? Set screws have flat ends. If you tighten the jam screw first the set screw on the shaft flat doesn't fully contact the shaft, only one small edge of the screw surface is biting. Reversing torques can easily shift the shaft to a position the flat screw no longer contacts the shaft. This lets the jam screw wriggle loose. And after a while, vibration loosens the screws until the gear is free to rotate.
