Z steps

Post by Rauno »

Hi everyone,
I have a strange problem: It seems like the steps in Z direction are way too high. I noticed that the object was way higher mid print than it should be when it's done. I have not changed any parameters like EPROM settings. The set screw on the Z-axis spindle is tight.
In this image you can see how the print should look like (gray part on the left) and how it looks now (white part on the right) these models have the same height and as you can see the white one is already too high. You can also see the layers are too far apart to stick.

The funny thing is that this only seems to occur with some prints. Others have no problem with layer hight.

The printer is a Felix 3.1

What could be the issue here?

Hi Rauno,
It sounds like a defective z-opto sensor. What printer is it?

Ah ok, that looks typically like it. If you are sure the setscrew of the spindle is fastened properly and the jaxagon nut of the spindle is properly placed in the z-axis bracket. Then please check the z-sensor. The wires, the sensor itself and board connections. Also update to the latest firmware. I think it then doesn't check the z-sensor all the time, but only during a home event.

I updated the firmware and the issue seems to be fixed.

Thank you very much for your support.
