Manual Mesh after homing Z

hey guys

Maybe i missed it BUT i have looked for something similar. I have a CoreXY 300x300x500. It works great and corners are level BUT there are areas where it dips. I have tried pieces of tape and paper between the bed and glass BUT on FULL bed prints it is sometimes a problem.

Is there a way i can do the normal Z MIN homing then MANUALLY flip down a BL touch or micro switch and then do a manual levelling exercise? OR even a automated levelling with a Z min ens stop only? i.e. using a Z offset greater than the endstop activation point?

Hope i made sense.

  • Compile with distortion correction. That adds G33 whcih stores a map in eeprom so you do not need to repeat everytime.

    Thanks for that. Is there a link ( i MAY be lazy) to a page that explains this process?
  • Repetier.ino describes G33 syntax. The config tool also descripbes the config parameter.

    AH awesome. Thanks.
  • I am downloading a new version of the firmware and I have enabled distortion.. when compiling it says z probing must be enabled then requires a pin. I want to adjust manually. Is that not possible. I.e. move to a point then lower z to a touch plate and lock in the Z value and so on

    If you enable and identify the pin you will be able to use the command G33.
     Pleas DO NOT try a G33 command by itself without a probe!!
    You can enable it but use the commands that can be done without the probe in place
    Read the syntax!!!
    G33 L0
    G33 R0
    G33  X<pos> Y<pos> Z<correection>

    Halfway down the page there is a section on Distortion Correction  - GOOD INFO
  • Thanks. Yes i saw the syntax etc. I just want sure if I actually needed a probe connected. I want to run manually for now. Adding a probe will be a royal pain at this time
  • You need to define a z probe. Select just an unused pin to fake it. Then use G33 R0 to reset matrix and set values manually only. Do not forget to enable correction.

    Great thanks :)
  • Hey @Repetier

    Thanks for the help. I was messing with this last night and it worked VERY well (obviously) is it also possible to have this done automatically using a min Z end stop and not a Z max? for the last 2 years i have always manually leveled but big beds are more of a challenge  if you want a 0.2 first layer you are in trouble!! 0.3 you are still ok.
