G29S1 not loading during print and G32 not leveling properly

[moe.adams9093]

Hello, I have a problem when I include G29S1 with my Gcode file and try to print a file and load heightmap my 4 Zaxis motors they don't move to compensate. I will post some files to help clarify the problem. I have duet ethernet and duex5 Zaxis motor connected first one at the mainboard and the other 3 connected to duex 5.

Zbrop is DC42 IR sensor

so this is after running G32 at 4 points and one G30 in the center. also checked after running G32 the front left&right corners lower than the rear ones. Thank you and your help will be highly appreciated

[jay_s_uk]

Heightmaps get unloaded whenever G28 is ran.
You need to make sure the G29 S1 is input after your last homing takes place.
I.e. include it as part of your start gcode, not bed.g

[moe.adams9093]

that's what I have on my gcode file

g28;
g32;
g29s1;

[engikeneer]

@moe-adams9093 are you entering

G29S1

OR

G29 S1

I think you need the space in between

If you're still having trouble, try manually sending each line from the start of a print one at a time and checking if the mesh compensation is applied/disabled via DWC

[fcwilt]

@jay_s_uk said in G29S1 not loading during print and G32 not leveling properly:

Heightmaps get unloaded whenever G28 is ran.

Why do you think that?

I have not found that to be the general case.

Hi,

Your current bed.g has a single G30 before the four G30 Pn commands.

The G30 should occur AFTER the four G30 Pn commands.

And since bed.g is part of the bed leveling process normally you don't load your height map in it.

I'm still having an issue where when I send G32 my 4 corners are not compensated correctly it only moves the front right side, does the have to do because 3 of my Z steppers are connected to the duex 5 and the 4th one is connected to the mainboard.

so I did some modification to my M558 code I added new parameters to see if I can get some more accuracy

NEW CODE:

M557 X50:450 Y50:450 S40                                	; define mesh grid

and here's a screenshot of my new heightmap

I'm not sure how exactly M558 A & S Parameters should work on the Gcode Dictionary it doesn't explain a whole lot if somebody can share how these 2 parameters can make significant changes. Thanks in advance.

Perhaps an example will help.

With A=10 and S=0.01 the firmware will probe each point up to 10 times trying to get two consecutive readings that are within 0.01.

If after 10 times two such readings do not occur then all 10 readings will be averaged.

I use those values for A and S and they work well.

Thank you for explaining it. I do have some questions changing the P500 parameter to something else may be like 525 will it help to get it lot more accurate. As you see my map it’s not leveled at all

Changing the P parameter is not likely to make much difference.

It could be that your bed is just not very flat.

What is it made of?

Frederick

[moe.adams9093]

Aluminum 6 mm thick I know the bed is not 100% I would say about 70% I have some twist In some spots

Is it cast aluminum tool plate?

Frederick

[moe.adams9093]

No it’s aluminum 6061

If you have the resources you may want to upgrade.

This is from one of my suppliers:

Cast Aluminum Plates have a precision machined surface for superior flatness, flat within .015'', and +/- .005'' thickness tolerance,

If you have the means you might be able to bash it into flatness, or at least take out the worst of the peaks and valleys.

bash it into flatness

I think machinists might cringe at that.
