differences between manual and automatic leveling

@gip_86 said in differences between manual and automatic leveling:
ufff spent the 4 last hours to upgrade to 3.3. holy sh... nothing was working anymore. had to switchover to bossa.
Now it works ok. but i get a heater fault. i will try to compare to my old config
If you copy-and-paste your new config.g file here (using the </> tag) we can all pitch in and take a look.
It's very likely just a syntax error.

so this is the new config. I hava adjusted all i see to fit with the old config

Hmm...
Everything seems correct.
When are you getting this fault?
What is the exact message your are seeing?
Thanks.

hi Frederick
this is the message i got:
Error: Heater 0 fault: temperature rising much more slowly than the expected 1.3°C/sec
Resume state saved
Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault -
@gip_86 Have you run a PID tune of your extruder and bed?
-
yes i have one done for the heater and the bed.
Bed:
Warning: heater behaviour was not consistent during tuning
Auto tuning heater 0 completed after 4 idle and 25 tuning cycles in 5317 seconds. This heater needs the following M307 command:
M307 H0 B0 R0.957 C113.0 D6.66 S1.00 V24.2
Edit the M307 H0 command in config.g to match this. Omit the V parameter if the heater is not powered from VIN.Heater:
M307 H1 B0 R2.746 C97.9:59.2 D5.41 S1.00 V24.2
one question:
after firmwareupdate now it takes very long to heat up the bed. is this normal? -
@gip_86 Have you got a config-override.g in your sys folder with the output of the tuning? You also need a M501 in your config.g if you do.
-
no, i have put the M307 in config directly..

and in config should only M501? -
It's perfectly fine to put everything in config.g
The config-override.g file is just to make it a bit easier as a M500 after certain operations makes the needed entries in config-override.g.
I have never used config-override.g - I move the contents to config.g and delete config-override.g

after pid tuning i have decided to add "R4700 behind the M308.
Now bed has heated really fast. Is there something agains R4700? I had this thing in my old config.
Now it looks like:
M308 S0 P"bedtemp" Y"thermistor" T100000 B4400 R4700
M308 S1 P"e0temp" Y"thermistor" T100000 B4400 R4700 -

If you don't have a R setting it is supposed to default to the correct values for your board.

Ok, machine is now running as aspected (but without mesh compensation)
I also have designed a new holder for the probe.
So and what are the best steps for next?

Have you made the configuration settings needed to use the Manual Bed Leveling Assistant?
Once that is done and the bed is level you should then proceed to get Mesh Bed Compensation working.

@fcwilt
ok i had done the neeed config and have leveled it. after several leveling, best i could do was about 0,03mm to adjust.then i had done a G29 and heres the height map:
Any idears?
-
I have four different printers all with cast aluminum tool plate for the bed and they all are different.
I haven't taken the time to find out why as they all print ok.
-
Ok, I also have a casted aluminium plate which is on both sides milled. I think my FR4 plate is the reason why it is so different. It’s a bit translucent.
Tomorrow I will give a try with the mesh.

I would agree the FR4 is likely the issue.

Yes but it’s a good Surface to print.
Could it help to decrease the probing points?
Or could it help to do a sanding of it?

@gip_86 said in differences between manual and automatic leveling:

I use a number of different print surfaces - all of the removable kind held in place by magnetic force.
I like being able to separately chose the bed heater, the bed material and the bed surface - the goal being to have the best combination of parts.
Could it help to decrease the probing points?
No, that would just hide the errors - to get the best results from using mesh compensation you would increase the number of points
Or could it help to do a sanding of it?
The changes you see in the height map are actually quite small - sanding would likely make things worse.
-
@gip_86 as @fcwilt said, I'd increase the probing points a bit. That way you can look for obvious points that are wrong and manually change then in the .csv file
You could also use the A and S parameters in your
G31M558 to do repeated probing at different points to improve accuracy.Final point, my heightmap on my corexy is a lot worse than yours because my gantry sags a bit. However, I still get pretty good results with mesh compensation enabled so have not bothered to redesign it. Ultimately what matters is if you get good prints, not whether you have a perfectly flat heightmap (though we'd all love that!
)Edit: corrected reference to M558
