Today I got my printer and unfortunately I have a problem with setting the height of the nozzle. I do everything according to the manual and I can not pull the Z axis below 170mm, and at this height there is still a centimeter gap between the nozzle and the table. After switching off the power supply, the nozzle can reach the table without any problems. There is no mechanical resistance anywhere. Also after connecting the power supply on (during initialization), the nozzle easily enters from the bed level to the top.
So when you click calibrate and manual 175 and click move it will not go down to 175? What happens if you keep pressing arrow up it will not increase the value? You keep doing that until you get to the bed and them confirm when all settings are correct. I believe then it should move pass your 175
Everything works, I was tired already yesterday and I did not notice that increasing the value by clicking on the + button at some point changes the increment by 0.1 and then the Z axis visually almost does not move. In addition, I had also set the nozzle height 170mm, so it blocked the maximum value. Thank for answer after all.
