#Printing 10mm above bed

Everytime I print, the nozzle prints 10mm above the bed. Ive tried using different slicers, adjusting my Z offsets. Is there something im missing?

  1. I adjusted z offset (commented out z and set my offsets)
  2. Stepper_z looks accurate
  3. Gcode copied from the klipper macro generator
  4. Start gcode pasted in Cura and I tried it with Orca too

Is your rotation distance correct on Z?

livid barn
#

it does look correct, im using the stock ender 5 + rotation distance which is 4

#

I adjusted my z offset and it was around 4, and then when i adjusted the z offset while it was printing, i got a value closer to 12. But after saving the new z offset and trying to print again, it goes back to the same height (10mm~ above the bed)

find your z-offset in your config and change it to 0. use z calibrate and save it

Thats how i originally set the z offset, I have a feeling its more gcode/ slicer related. its just not applying or something

I finally fixed it

originally my max z velocity was set to something like 35 and accel was set to 350
