@Phaedrux perfect i think i have this right.
I think i only have two things left wooohooo
-
I have two fan bars on the DWC but they only seem to move together and not individually. How would i make them independant?
-
When doing the true bed leveling i keep getting this response. But i can see where to amend either G32 or G29

Those two sliders are for the same thing. The tool fan slider is for the fan of the currently selected tool, which is fan0, and the fan0 slider is for fan0. If you had two tools with different fans, the tool slider would always control the fan of the currently selected tool and you'd have 2 sliders for each fan as well. There is a little button link near the fan sliders "change visibility" that will let you hide one of you like since you only have 1 tool.
To get rid of those errors we need to change the M557 grid spacing to take your probe offset into account because it can't reach some of the areas you're asking it to.
Try
M557 X5:185 Y5:205 P6 -
@Phaedrux Ahh ok fine thats ok then ill just hide one of them
in regard to the M557 X5:185 Y5:205 P6 i have updated this.
and am now getting this

also are you able to break down that code so i can start understanding the structure and meaning? I think it will help for the future (rofl)
I would on SAP and code regularly so i think if i started understanding what everything means i maybe able to start fault finding alittle better
-
Well to define a good M557 you'd take your M208 axis limits and your G31 X Y offsets and choose points such that the probe is able to reach them.
A good way to do this is to draw a diagram of your bed showing the size and probe offsets and then you can see where the probe is able to reach.
It's skipping the Y5 area now, but I thought it should be able to reach it because the probe is inline with the nozzle (y0 offset) and the Y axis goes from -10 to 220.

220
Thank you for this!! i now am not getting that message. I have sorted the parameters and i think i have as bigger printing area as i can get.
However i am now getting this
Warning: the height map has a substantial Z offset. Suggest use Z-probe to establish Z=0 datum, then re-probe the mesh.
36 points probed, min error -1.793, max error -0.002, mean -0.966, deviation 0.483I have tried to recalibrate the BL touch using this
https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe
As i read that, that maybe the issue, but it keeps coming up now
Any ideas? also as a side point (pardon my ignorance) should the BL touch auto adjust the Z axis depending on the height or do i still have to manually have to adjust using the height map?

this mean you are loading the mesh before you have homed the printer.
check your start code
if you have G28 and G29 make sure that G28 comes first. -
@Veti said in unusual/unnerving noises + error codes:
G28 and G29 m
So i dont believe im using a G28 code. Should i be?
-
G28 calls homeall. so at some point you are using it to home the printer otherwise it wouldn't be moving.
Please post your current homeall.g and config.g and your slicer start gcode section.

@PR1OR said in unusual/unnerving noises + error codes:

Yes. The slicer will insert some gcode commands before the print starts to set temperatures, home the printer, etc. This is where the G29 should go to either load the heightmap or create a new one.

Yes that would be it. So if you want to enable mesh compensation you would add G29 after the G28 in the start gcode section to probe the bed and create a new heightmap. Or if your bed is pretty stable you can use G29 S1 to load a previously created heightmap.
As long as you're doing G28 before the creation of the heightmap with G29 you shouldn't get that Z=0 datum error.
@PR1OR said in unusual/unnerving noises + error codes:

I'm not sure what you mean by this. When you have mesh compensation enabled it will automatically adjust the position of the nozzle up or down to account for the heightmap. The displayed Z position won't change however because it's trying to keep the nozzle distance from the bed the same as it moves around in X and Y.
Can you create a new heightmap by running G28 and then G29 and post a photo of the heightmap display?

@Phaedrux thanks i will try this on my next print, i have one going fairly well at the min so dont want to stop it haha
and the second point is the answer i was hoping for!! thanks again
