Adjust Z-Height with G-code?
October 29, 2019 12:58PM
I need to give my Mendel90 a service as prints are not as good as they could be and the first layer is not sticking properly. When I have re-leveled the bed, I need to replace the kapton tape on the Ikea mirror tile, and found what the new Z-Height and E-Steps are is there a way to change these using g-code instead of altering the config.h file in the arduino gui and uploading it?

Since I last did this I have installed a raspberry Pi 3 running Octoprint. If it is not possible to alter the Z-height and E-steps with g-code then I will disconnect the Meltzi to Pi usb cable and upload the arduino sketch using a PC to Meltzi usb cable like I have done in the past but it would be more convenient to do it via Octoprint and g-code.
