I had a few issues with the first layer that I found were corrected by increasing the print temperature. For me the esun pla seems to print best at 220c.
I had a simular deviation until I tweaked my config.g with my settings and now use the 6 point calibration.

Just rebuilt my effector today and tweaked a few things, my deviation on a 6/10 calibration cycle is down to 0.033, it had drifted up to 0.055 (from normally being 0.04) and I started getting first layer issues which is why I did the rebuild.
7.661!, there is something wrong there, what cycle are you using?

It could be, but I was chasing a small deviation, it turned out one of the balls was loose and I tweaked a few positions, I did post my 6/10 bed.g file for someone recently, here

After running the calibration a few times ( I think at least three) you can run the M665 and M666 commands to get the values for your printer and then update the config.g file with your settings. Then after you power off and back on again you only need to run the calibration once to get a good deviation. Note that the nozzle is clean when you calibrate.
The last part of the m666 command controls the Z height at the start of the print. Although some software like Simplify3d has this adjust as part of the first layer. So Z0.52 is just a bit off the bed surface.
Here's an example of my output and config.g settings - don't copy these verbatim just run the calibration and few times to get your own.
Command outputs
;5:25:46 PM M665
;Diagonal 160.00, delta radius 81.51, homed height 177.02, bed radius 75.0, X -0.14°, Y -0.62°, Z 0.00°
;5:25:49 PM M666
;Endstop adjustments X-0.13 Y-0.39 Z0.52
Changes to config.g
M665 R81.51 L160.0 B75 H177.02 ; set delta radius, diagonal rod length, printable radius and homed height
M666 X-0.13 Y-0.39 Z0.52 ; put your endstop adjustments here

I tried your file, the 10 point is awesome and worked great, but almost too great. it left no space at all between the build plate and the nozzle, to the point the filament couldnt be extruded. I have tinkered a bit, but giving my very basic knowledge, i didnt want to change too much. any suggestions?
You probably need to adjust the h parameters, see my last post on the thread with the 6/10 file

You need to adjust the H parameters, the H parameters in my bed.G are unique to my printer which due to the modification I've done is.... unique.
to set the H parameters first set the step movements to half, so your smallest jog step is 0,.05mm (this is done somewhere on the web interface.
now note the position of every probe move in the bed.g
move to each XY position in the bed.g individually and repeat this process
1 do a G30
2 jog the Z axis down until it just traps a piece of paper between the nozzle and bed
3 note the Z height
4 enter this Z height into the H parameter of that position in the bed.G file.
When you have done this for all positions redo the calibration and M666/M665 parameters.
If it still close to be after having done this then you can just offset the Z axis.

Sean, you might like to try my 1.09m-dc42 firmware. It corrects a bug whereby the Z=0 height was not quite correct after running G32. The size of the error depended on the difference between the X and Z endstop adjustments, which is quite large in your case.

Thanks! I may just do that. I'm reluctant to do very much, as I am trying to diagnose/fix my network connection or I will have to send my duet back. But in the meantime, what have I got to loose!
