@fcwilt I am trying to figure out the height of the offset for that from the center of the bed. Then I lower the nozzle to 0, I adjust the bed with the paper, I do a height test to know how high it is and I modify it in the config.g. This is how I configure the distance from the nozzle to the bed.

RE: dual z axis sync and bltouch issues..posted in Tuning and tweaking
@fcwilt many thanks! so apart from eliminating the G29 from the bed.g
I think I have understood the rest and I believe that I have followed the same process, I will tell you if I am right or I am doing something wrong.
G1 Z5
G90
G1 X150 Y150 F6000
G91
M561
M564 S0
M291 S3 Z1 R"Down to zero" P"0"
G92 Z0
G1 Z5
G30 S-1once I have the z offset in the config.g this should work fine, right?
I really appreciate your interest and help, tell me if there is something that I am not doing well or that I can optimize.
Thanks

Thanks @droftarts @jay_s_uk @fcwilt
I think I am making some progress with the issues, which I had, at the moment I can do a more or less decent print test, I have taken some of your suggestions and "I think" that I am on the right track.
- The steps I have taken have been
Z leadscrew coordinates (-20.0,100.0) (325.0,100.0), factor 1.00, maximum correction 1.00mm, manual adjusting screw pitch 0.50mm
Then:
3/4/2021, 7:11:40 PM G30 S-1 Stopped at height 0.805 mm 3/4/2021, 7:11:08 PM Leadscrew adjustments made: -0.065 -0.117, points used 2, (mean, deviation) before (-0.084, 0.011) after (0.000, 0.000) 3/4/2021, 7:10:42 PM G32 30 points probed, min error -0.168, max error 0.130, mean -0.023, deviation 0.068 Height map saved to file 0:/sys/heightmap.csv

dual z axis sync and bltouch issues..posted in Tuning and tweaking
Hey Gang,
I have a CR10S with 2 Z motors, every X time, the motor on the right seems to get out of adjustment or not synchronized well, but I never get a correct bed leveling, I always have to move the rod a little on the side of that motor.
I leave my configuration waiting for someone to tell me if I have something wrong configured or I have left something, I thank you in advance for your help.
