Help Z-Axis calibration Nextion LCD

Hello all,

I’m new to Nanodlp and I want to build my own dlp or lcd printer.

I used the next components:

- Raspberry PI3   install soft last build
- Arduino Uno      install soft GRBL 0.9
- Ramps
- Nema17 stepper motor
- Touch LCD Nextion 3.5 enhanced   install soft TouchScreen-For-NanoDLP-master

When operating with the LCD nextion, the top button and calibration do not work on the z-axis setup page. Nothing happens after they are pressed. I have one limit switch on the bottom of the Z axis on the printer. The incremental buttons work. Someone could advise how to fix it.
Sorry for the translation, only WEB-translator.

Re: Help Z-Axis calibration Nextion LCD

i will try, but i am no expert. you got pretty far!

what file did you install for the touch screen?

did you look at this page? https://www.nanodlp.com/forum/viewtopic.php?id=2069

pay attention to enabling the serial port and look at the bottom where you have to select the serial port for the nextion

if you can not tell which port it is on, unplug the RAMPS and use

lsusb

or unplug the RAMPS and reboot the raspi.

Re: Help Z-Axis calibration Nextion LCD

- version for Nextion I have installed this

- I've done everything from this site

I have no problem communicating with the display. All touch buttons work on all pages, but nothing happens on the z-axis calibration page when you press a calibration or measurement.
Looking at the Ramps terminal it does not send any g-code.

- the up and down buttons also work

When you press the floor button, it sends G28. it's alright.

But when you press the calibration button nothing.
