A10 R0.5 S0.003 B0
just to check add this to the end of the code i already have ?

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?
This is from the print

Yup, add it to what you have already in your M558. Did it change the resulting heightmap at all?

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.

But can i simplify it or need much of it?
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..
