Nozzle z-axis leveling

Postby ExLondoner » Tue Jan 31, 2017 3:55 am

I've searched but can't seem to find a threat that explains the most accurate way of leveling the left nozzle with the bed. Is there a prefered method?

The method I've used (since there were no instructions) is as follows:

1. Move the Nozzle via the control screen a little further in so that it's directly over the glass bed.
2. Hit the Z Home option
3. Slide the 0.2mm spacer and hit the Z Home option until there the height feels correct.

The issue I have with this is that it's not a sure way to level the nozzle with the other areas of the bed, having checked random spots there are definitely variances.

This is all leveling exercise occurred due to several failed prints!

Please refer to the quick start guide comes with the printer.
Use the z screw to control the bed gap.

basically you can't level the bed without modifying it. To get around that Raise has you print everything on a raft.

Thanks Walshlg. That's a big flaw in the machine.

the bed mod directions are in threads around here, one thing left out is make the spring for the center screw twice as strong as the springs for the periphery

why make the center spring so much stronger? could you accomplish that by using two springs (not sure they would fit into the screw, but...)

used the full 9 screws and the sides have a huge mechanical advtantage over the single middle spring leaving the center of the plate often bowed down
