Correction of heightmap is not really working

@fcwilt
hello,

works,

we had a mismatch config_probe.g against probe_config.g

with the variable Z{global.g_probe_z_trigger} it´s not working

as soon as i add a value for z it works.

As @Phaedrux pointed out the Z trigger height should be the same regardless of which buildplate is in use.

But using a variable doesn't hurt if you want to be able to easily change the Z trigger height without stopping to edit a file.

I verified that using a variable works but it is required that the variable be created in config.g before any attempt to use it.

I think I recall you initially declared it after the call to config_probe.g (the file name doesn't matter - if you prefer another name just check that you use the same name everywhere.

@fcwilt This has been great, I am having the exact same problems as @ICY_SNAKE with the same machine. V3.3, I have followed and made all the same changes.

But I am having a Errror: in file macro line 6 column 43: G31 : unknown
variable 'g_probe_z_trigger"

I don't understand what that is ?

Did you create the variable in your config.g file as I specified in my example?

I am just not picking up this coding. I have spent 5 days straight on this.

Question - So when a Error pops up it is there to tell you there is a problem and to point you in the direction of the problem to fix the issue, I assume ?

So, when I get a -
Error: in file macro line 44 column 10: meta command: 'break' was not inside a loop

How do I know what macro, and column is the spot on line 10?

@sculpt-fabricator

Amazing.

What are the odds you would have global variables with the exact same names as mine.

In any case the variable mentioned in the error appears more than once in your config.g file but they are all commented out.

Enable the second one (the one with 1.9) by removing the comment character.

Also I see these two commands:

M558 P9 C"^zprobe.in" H5 F120 T6000 A1 R1
M950 S0 C"duex.pwm5"

They should be moved to your config_probe.g file. If they are already in that file simply remove them from your config.g file.

Well I test each macro as I code it so I know which macro is creating the error. Then since the error messages tells me what line and column I can focus in on the error.

I don't move on to some other coding until the macro is error free.

Do you have a bed.g file?

If so post it here, please.

@sculpt-fabricator said in Correction of heightmap is not really working:

that is my bed.g
and config_probe.g

OK your config_probe.g file looks good. So remove the commands I mentioned from config.g

Please upload your bed.g file using the "upload file" tag. I will edit it to correct the errors.

You simply have not used the required indentation.

Got the lines changed in the config.g

Here is the bed.g

@fcwilt

So another question. Modix had a Macro -
Automatic tilt calibration + Bed Compensation - 101 points

That Macro has all changed now with your code correct ?

So how do I run the bed tilt calibration
and the bed probe calibration ?

I am confused on it I wipe those clean and add a M98 P"bed.g"
and run it trough the macro
or just type that into the console comand ?

fcwilt

@sculpt-fabricator

The current approach that the DWC expects is this:

the file mesh.g is used to create the height map needed for Mesh Bed Compensation.
the file bed.g is used for Manual or Automatic Bed Leveling.

A G29 command executes mesh.g and creates the height map.

To use the height map you would have a G29 S1 command somewhere in your print start code.

A G32 command executes bed.g.

I use G32 as part of my home all code.

So it looks like you are already using the correct approach.

See if this bed.g file works for you:

Thank you very very much, I will give it a try

Sculpt Fabricator

@fcwilt
I got this -

Does that command need a ; in front of it ?

fcwilt

@sculpt-fabricator

Sorry there is a missing comment in front of that line.

It should be this:

; --- set Z=0 datum which can be affected by leveling ---
 
G1 X270 Y270 ; move probe to center of bed - set values aaa and bbb as appropriate
G30          ; do single probe which sets Z to trigger height of Z probe

@fcwilt
Ok now I cant get the bed tilt leveling right.
I am not understanding the placement of z screws

bed.g M671 , needs to match the config.g M671 correct ??

 M671 X-189:640:640:-189 Y643:643:-64:-64 S10                        Anticlockwise

why does it say anticlockwise
In my bed.g it says to run the probe pattern -

 ; run leveling pass
 
  G30 P0 X5 Y5 Z-99999      ; probe near a leadscrew
  G30 P1 X570 Y5 Z-99999     ; probe near a leadscrew 
  G30 P2 X570   Y580   Z-99999     ; probe near a leadscrew
  G30 P3 X5   Y580   Z-99999 S4  ; probe near a leadscrew and calibrate 4 motors

But that is running from the left rear , clockwise

But when it runs the Tilt calibration, it starts at the front left and go's to the front right, and so on, Anticlockwise.

In the Gcode Directory it examples M671 going clockwise

I am stumped !!

@fcwilt
also If I skip the tilt calibration and go to Bed compensation,
I can strategically place a high spot under one of the probe points.
and it shows me that the map is 90 deg out.
to correct it, it would have to turn 90 deg Anticlockwise.

if that helps
