Saving with M500
Hi All,
I've just made my very first delta autocalibration. Everything went well except saving with M500.
When I look at the directory with system files on DWC after sending M500 there is no config-override.g.
I thought it is created automatically by sending M500.Edit:
The file config-override.g was created after rebooting Duet.
Is this always like this?
Are the new values stored in config-override once I send M500?
Or stored in memory and appear in config-override after reboot?Greetings,

RE: Delta printer calibration procedure
@dc42
I've just bought BL Touch.
There is in Duet3d manual: Adding trigger height corrections to the bed.g file
What is this actually for? I'd guess one need to do those corrections when there are
any points on bed surface that falls out of probe effective trigger height?
For BL Touch it is from 2,3 to 4,3 mm. So when all the bed is in this range I don't need to do it? -
RE: Delta printer calibration procedure
@dc42 OK. Thank you.
But now I've examined one of my build plates by touching it with the nozzle in different points and get values from 14,30 to 15,15. I guess the whole bed is a bit tilted. It gives 0,85 mm difference. I don't know it it is big... So when I go with G32 for the very first time with 6-factor calibration and save the results will it eliminate these differences? Or somwhere in higher parts the nozzle will hit the bed? -
RE: Delta printer calibration procedure
@nikscha Thanks for your time. I was not very clear. I'd have normal print bed e.g. plywood or plaster board. I think both of it have fairly even sufrace. The material I'd print with is clay.
But yes, I need to change the plates every print so they can differ in few milimeters each other.
So I will buy a z probe as @Phaedrux suggests. I still not sure which one. As I wrote few post above it could easily get dirty with clay. For now I'd bet on BL Touch. -

@Phaedrux Thanks a lot. Now that is clear to me. Have a nice day!

RE: Delta printer calibration procedure
@Phaedrux Sorry for such simple questions. I read "Calibrating a delta printer" in user manual
1000 times and read lot of forum threads but I am totally new on this field.
So I command G28, then G32, then save? And everytime I run new G32 the "fresh" results will override the saved ones, right? Till I reboot my Duet, right?
And for saving should I use this procedure:?
If you are running firmware 1.17 or later, you can run M500 to save new M665 and M666 commands in the config-override.g file. Then, if you have an M501 command at the end of your config.g file, it will run config-override.g at that point, so that the new commands override the ones earlier in your config.g file.
Many, many thanks... -
RE: Delta printer calibration procedure
@Phaedrux Thanks.
Could you please look at this procedure? As I wrote before I would print clay
and change print bed very often.- turn on the printer
- run autocalibration
- do not home
- start print
- when the print is finished change the build plate
- home the printer
- run autocalibration and start new print?
Do I need to save the autocalibration results evertytime in this case?
Do I need to home in point 6? -
RE: Delta printer calibration procedure
@Phaedrux I read about DC42 IR sensor and BLToutch probes and don't know which to choose. What do you suggest in my case? IR sensor sounds good but I read that it needs 1,5 mm distance
from the nozzle. I think it is a bit to close and can be risky with clay. Can get dirty easily.
