Auto Bed Leveling Map on Tronxy X5SA
-
Hi, yes it does have 2, and connected to z1 and z2 but they are moving in sync with my eye and with a spirit level on the bed.
they are 1.8 step
-
The bed may be level according to your spirit level; but is the X gantry parallel with it?

@pr0xyfl00d3r As a tip, there is a nice assistant for manual leveling that you can use to get it at least somewhat right for a start:

@dc42 i have now checked the x axes and this also level to the bed in multiple places around the bed

I'm using the stock NPN sensor that comes with the Tronxy X5SA
I have connected this to the Z Probe IN for Signal and + and - to an Always on Fan with 12v turned on,
Stepper Motors
Step Angle:1.8degI have just done another Auto Bed Comp and this what i got.

It's totally possible that the bed is actually that warped. The color map exaggerates the differences to make them easy to see, but the actual deviations aren't that extreme. -1.5 to +0.4mm wouldn't surprise me for a Tronxy bed.
What happens if you print a test file like this? Does the bed compensation work to keep the first layer in contact?
-
The bed is not warped works perfect with factory board setup, i am running the file you posted and video what is does, when i tried a file earlier it rams in the heatbed

M558
Can you try adding
A10 R0.5 S0.003 B0to your M558 command?This will set it to try up to 10 probes until it gets 2 consecutive readings within 0.003, and it will wait 0.5 seconds between probe travels to let the machine settle, and will disable any heaters during the probe move to eliminate any electrical interference.

I will after this file is finished..
in my simplify3d setting for the starting script i had the following
G28 ; home all axes
G29 ; auto bed level
G1 Z0.2 F3000 ; get ready to prime
G92 E0 ; reset extrusion distance
G1 X100 E10 F600 ; prime nozzlewhich i changed to
G28 ; home all axes
G29 ; auto bed level
G28 ; home all axes
G1 Z0.56 F3000 ; get ready to prime
G92 E0 ; reset extrusion distance
G1 X100 E10 F600 ; prime nozzlenow it did not hit the bed and does go through the print, the 0.56 i got from following https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe
But can i simplify it or need much of it?

just to check add this to the end of the code i already have ?

This is from the print

Yup, add it to what you have already in your M558. Did it change the resulting heightmap at all?
@pr0xyfl00d3r said in Auto Bed Leveling Map on Tronxy X5SA:
the 0.56 i got from following https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe
That would be used in the G31 command to tell the printer how far the nozzle is from the bed when the probe triggers, but isn't useful elsewhere. You can prime the nozzle at whatever height you like. I use 0.3, but as long as it's doing what you want for the prime it can be whatever height you want. The slicer will move to the correct first layer height afterwards. Though it should be noted that having a Z move like that to prime the nozzle can confuse the DWC and result in the first layer height and layer counter to behave oddly. It may be better to move that nozzle prime into it's own macro that lives in the sys folder on the Duet. Then you can use M98 0:/sys/NozzlePrime.g to call it in your slicer start code.

That doesn't look too bad... Can you try again, this time with no brim, single perimeter, and a single layer of 0.2? That should make it easier to see.

Once you have the heightmap sorted out you may be able to get away with just doing a single detailed G29 once in a while and then loading the saved heightmap before the print rather than doing a less detailed but faster G29 before every print. It will depend on how well your bed maintains it's geometry/leveling.

Ok retrying the file...
-
What can i do to stop the Heatbed and hotend warming up before the bed leveling in the start script?
i keep getting Error: Z probe readings not consistent
-
i have added Z Baby Stepping
Current Offset: 0.2 mm and seems to be ok, i think i can see a slight bubble to the sheet on the bed -

The slicer will add temp commands automatically if you don't add your own, so you could add some after the homing commands if you want.
The probe readings not consistent error is because we've set the tolerance quite low with M558 S0.003 You can increase that value to make it less sensitive I think the default is 0.005.

Ok, will have to look into added some code maybe, thank you for your help with this is very appreciated.

Has the height map image improved at all? Is the first layer going down better?

Yes the map has flatten by half ish..
