Z-Height not correct

Recommended Posts

Posted · Z-Height not correct

After installing a custom firmware (tinker) my Z-axis does not work correctly. All prints are only 50% high, as the original size in Cura. Y/X axis are working well.

And I notied that the heatbed is during the calibration process much too low! The bed is only 150mm away from the 0 position (ground).

Can I change this wrong setting in the firmware, or also in Cura´s machine setting? I have tried it with the Marlin configurator...but don´t know what to change.

When you say 50% high you mean that the actual object is being printed in a compressed height? or that it stops after 50% ?

Did you change something on the electronic card?

Yes, the object is in a compressed height.

Because a Z-switch error, I had to change the E1 and E2 port. So the Z-axis motor is in the E2 port and I have a customized firmware (tinker).

Extruder motors have different steps per mm than the x/y/z motors - you need to adjust that in your customized firmware for E2.

Indeed, and i don't see any good in putting the Z on the E2 because of a Z-Switch error

 

It shouldn't be a problem. The only issue, if done properly changing the pins.h definition, is that UM2 boards for the Z stepper work at 1/8 but all the other steppers work at 1/16 so the Z on other stepper would need x2 steps/mm or adjusting the steps to 1/8 on the firmware, since Z stepper 1/8 is a limit from a physical switch of two pins that by default is open (1/8 ).
