@fcwilt jup its 3.760

Are you still running the "PLA" macro?

If so what does it look like.

G31 X-31.7 Y3,16 Z3,760 P25

And that is the height reported by your calibration routine?

Hi,

Recall that before creating a height map with G29 S0 or before loading the height map with G29 S1 you need to position the probe to the center of the bed and do a single G30 to set the Z=0 datum.

Having set the Z trigger height to the value as reported by your calibration routine did you go back and re-create the height map using the new value?

Are you also setting the Z=0 datum when loading the new height map?

I mentioned that changing the Z trigger height to accommodate different filaments was not a good approach - one reason being is that it will mess up setting the Z=0 datum which may cause the height map to not work right.

@fcwilt i reprobed everything still same problem, could it be something with the zmin stop and the prob are on 2 diff heights? if yes what would be the solution

Hi,

I've re-posted your files using the </> tag - it saves everyone the trouble of downloading your files.

Would you look at them and verify they are your current files?

Thanks.

@fcwilt I adjust the Z offset so I don't have to remember to do baby steps on every print. Currently I only change the filament when I run out on the spool.

@fcwilt I adjust the Z offset so I don't have to remember to do baby steps on every print. Currently I only change the filament when I run out on the spool.

As I said changing the Z trigger height may cause the height map to not work correctly.

And as I said you can use the filament management feature of DWC to allow you to select different filament types and make any adjustments desired to things like extruder temp, extrusion multiplier, baby step settings and more.

You don't have to do it for every print - it will happen automatically if your "print start" code invokes the the command needed to trigger the changes specified by the current filament.

Here is an example of a filament configuration file. Every filament type you enter into the DWC filament management feature will have it's own configuration file.

M221 S100 D0    ; set extrusion multiplier
G10 S200 R0	; set extruder temps
M140 S60 R0	; set bed temps

Here are the commands you would place into your "print start" code that will invoke the configuration file for the currently selected filament type.

T0		; select tool 0 so extruder commands below will work
M703		; configure selected filament

So once you select a filament type it will remain selected and every print will run the commands you have entered into the configuration file for that filament type.

@fcwilt In my slicer's start gcode, I call the macros, then home, then G32 which does a G29 S1 or S0 depending on if it finds heightmap.csv. Never had a problem with the heightmap working correctly.

yaa its my current

fcwilt

@TristanKoeln

Thanks.

So if they are current there are two things wrong that may be causing you problems.

In homeZ.g there is that G92 Z0 after the G30 that is setting the Z position incorrectly. Since the G30 leaves Z in a known position you can simply remove the G92 Z0 or if you wish to move Z to some other known position you can use something like G90 G1 Z10.

In homeALL.g there is G92 Z10 after the call to homeZ.g which again will set the Z position incorrectly.

And the M584 command is not needed since it occurs in your config.g file.

What is the intent of the M280 P0 S90 command? If you issue deploy/retract commands using M280 instead of M401/M402 then the firmware may lose track of the state of the probe.

so i edit the files

i got the nozzel once close to the bed.. to close after i made the calibration process again the problem from the start came back

TristanKoeln

@fcwilt and the M280 is just to move the pin in a save position just incase it isnt

Did you leave the G92 Z10 in homeALL.g?

And did you understand what I meant about the firmware losing track of the state of the probe if you didn't use M401/M402?

Frederick

TristanKoeln

@fcwilt the G92 is only in the home all file ;
not realy

fcwilt

@TristanKoeln said in Heigh error after calibrating:

@fcwilt the G92 is only in the home all file ;

Just before that G92 Z10 you have a call to homeZ.g which executes a G30 and sets the Z=0 Datum and leaves the Z position at dive height + Z trigger height.

You can't just tell the firmware with a G92 that the Z position is something else and expect things to work.

You can change the actual Z position with a G1 Znnn command but not with a G92 command.

not realy

When you use M401/M402 the firmware keeps track of the state of the probe (retracted/deployed).

When you use the M280 command to retract/deploy the actual state of the probe and what state the firmware thinks the probe is in may conflict and possibly cause problems.

if im setting all the G92 Z(dive + trigger geigh) could that solve the problem

Hi,

You don't need to.

The G30 leaves the Z axis position at dive height + Z trigger height.

Setting it again with G92 to dive height + Z trigger height is redundant and serves no purpose.

G92 is useful in certain specific instances and unless you are dealing with one of those instances you should treat the presence of G92 in your code as very suspicious and likely should be removed.

When in doubt ask.

Frederick

TristanKoeln

@fcwilt I removed all G92, and relevled everything, still not working
