    Can you post the heightmap.csv file generated by a G29 that giving you bad results?

        I can't see anything wrong with your height map, although you have a couple of fairly large errors at y=-60 and X= +/- 20mm. What sort of skew are you getting?

          I haven't let it print more than a couple of perimeters, it's pretty wild and I can't even make out what the part is.

            Is it just the Z height that is behaving wildly, or X and Y as well?

              OK, I think I found a problem that could explain what you are seeing. I suggest you roll back to dev6 until I have dev8 ready.

                Ok, done! Glad I'm not completely crazy. The x and y are really skewed, z axis does some crazy things as well, especially when pausing the print.

                  I have just released 1.17dev8, which fixes the issues I introduced in 1.17. I don't anticipate making any more major changes before 1.17 release, just fixes for any new bugs.

                    Cant seem to get it working

                    Updated. restarted several times

                    "No valid grid defined for G29 bed probing" is error
                    this is in my config.g

                    M557 X20:260 Y0:240 S10 ; define a grid covering the XY area indicated with the specified grid spacing

                      hmm when i increased Spacing from S10 to S20 it started working.

                        With your original M557 command, you should get an error message saying that there are too many probe points - except if the M557 command is in config.g then you won't see the message.

                            DC42, on my delta I don't use any XY offset for your IR probe when running G30 autocalibration and it works fine. When I run G29 grid levelling after, should I have entered an XY offset via G31 first or not? My probe is offset about -40mm in the Y direction.

                              Grid leveling is working incredibly well. Never had such a good first layer over my entire bed.

                              Thank you DC42

                                I'm glad it's working well for you!

                                The maximum number of points is currently 121 on the wired Duet and 441 on the Duet WiFi. However, the underlying grid is rectangular so when using a circular probing area the actual max number of points is about pi/4 times these values.

                                You should configure the probe offset. During auto calibration the probe offset is ignored.

                                  You mean that G29 should have the same X Y Z offsets as G31 in config.g?

                                  If Z probe section in config.g looks like this,
                                  [c]; Z probe section
                                  M558 P1 X0 Y0 Z1 H3 F100 T5000 ; Smart IR Z probe, used for homing Z axis, dive height 3mm, probe speed 100mm/min, travel speed 5000mm/min
                                  G31 P500 X-60.0 Y0.0 Z1.30 ;Set the probe height and threshold
                                  [/c]

                                  then bed.g should look like this for Auto bed compensation?
                                  [c]; bed.g
                                  ; M561 ; clear any bed transform, otherwise homing may be at the wrong height
                                  G28 ; home the printer

                                  M557 X10:275 Y15:190 S25 ; define a grid covering the XY area indicated with 25mm grid spacing
                                  G29 X-60.0 Y0 Z1.30 ;probe levelling grid with prob offsets from config.g
                                  [/c]

                                  Edited. Removed .1 from G29

                                    No, I mean set up the XYZ offsets in your G31 command, and G29 will use them.

                                      is there a way to fade the grid correction after a certain amount of layers. I noticed that its still adjusting Z height even after 50mm of print height.

                                        Hello,

                                        I am trying to run the new grid correction and running into an issue. I have this in my config.g
                                        G31 X0 Y0 Z19.4 P500

                                        and the bed file

                                        G30 P0 X0 Y0 Z-99999

                                        ; Probe the bed and do 6- or 7-factor auto calibration

                                        G30 P1 X0 Y-85 Z-99999 ; between X and Y towers
                                        G30 P2 X73.6 Y-42.5 Z-99999 ; Y tower

                                        G30 P9 X0 Y0 Z-99999 ; centre, and auto-calibrate 6 factors
                                        G30 P10 X0.00 Y40.00 Z-99999 ; Z tower
                                        G30 P11 X-34.64 Y20.00 Z-99999 ; between Z-X towers
                                        G30 P12 X0 Y0 Z-99999 S6

                                        M557 R90 S20
                                        G29

                                        The auto calibration works fine for my delta. When it runs the G29 command the zprobe doesn't report/trigger properly (it is 19.4mm) above my bed. It pushes my probe out of the way down and gives the message

                                        "Zprobe triggered before probing move started" (if the printer is not homed to top)
                                        OR
                                        "Zprobe was not triggered before probing move" (if the printer is homed before running)

                                        I assume the G31 isn't being read for G29? what option do I need to set for the probe to trigger correctly? Sorry if this has been answered for a delta, haven't found it in the threads.

                                        Thanks,
                                        Jim

                                          I think that your very large Z probe trigger height has exposed a bug in the G29 probing, which I will fix in today's release.
