Auto calibration error
-
Does your config-override.g file have M665 and/or M666 commands in it? If so, delete them.

@dc42 there is no config override file being created after auto calibration! can this be due to the macro files that i deleted accidently?
-
Auto calibration does not in itself create a config-override.g file; but you can send M500 after running auto calibration to save the values.
So was there a config-override.g file on your system, or not?

@dc42 I cannot see any such file!
-
@dc42 I tried M500 command still the same issue the when home after 1st auto calibration the head position goes random for xyz. Though now the config override file is created.

-
Please can you change the S parameter on the final G30 command to S-1. This will cause the firmware to report the height errors without making any changes. Then report the height errors here.

@dc42 I did the same as you said but the problem has just dissapeared now, i dont know how( i am able to auto calibrate it one after other). But there is one peculiar thing happening that ( I deleted the config-override file before i started the auto-calibration) now when i try and pass the M500 command no config override file is generated.
-
@dc42 it is now showing the config override file as well!

I'm glad it's now working for you. If it goes on working, please mark this thread as Solved by editing the title.
Duet Web Control doesn't update its file lists automatically. You often need to click the Refresh button to see the latest changes. This may be why you didn't see the config-override.g file at first.

@dc42 0_1542832005147_config-override.g This file is generated after auto calibration 8 factor. when i input S1 it is fine, but when i use 8 factor calibration head values go random(read 999.99) all of a sudden. I need to do 8 factor because my bed is showing convex(4.5mm error at extreme edge) still but isnt(checked seperately).
-
I suggest you connect a PC running e.g. YAT or Pronterface to your printer via USB, send M111 S1 P4 to enable Move debug, then run auto calibration. It will send details of the calibration calculations to the PC. If the auto calibration results in nans and you post that output here, I may be able to work out what is going wrong.

-
Bed probing is giving extremely large height errors, up to 150mm.
-
The second and third probe points in your bed.g file are unreachable using your current delta parameters. This may be because you are using a Z probe offset from the nozzle. You need to move them closer to the centre.

@dc42 do I need to change my effector that means? I'm close much to the center as i can get!
-
No, I mean you need to move the XY positions of the 2nd and 3rd G30 commands in your bed.g file closer to the (0, 0).

@dc42 I have done the same of moving it close to zero but still it is doing the same thing. now surface is only off by 0.5mm at edges but after calibration head position still changes to random
(999.99) -
@yatinsd additionally it just hangs up on negative y axis movement moves only after i home the printer.

Please post the bed.g file you are now using, and the output from Pronterface as before. Also your current config.g file.
