2.03RC5 leveling issue

SPAX

Since I installed 2.03RC5 builds after 2.02 I have an issue with leveling.
Everytime i do a bed level it gives me a different height.
-home, g32, m500
Everytime a different height H*** (454, 461, 475, 480)
Already calibrated the Z probe trigger height.
Nothing to work....

2.03RC releases are no longer supported, because 2.03 has been released.

Veti

there were some changes to leveling since the rc. please update to 2.03 release and try again.

also why 0.1?
M208 Z0.1 S1 ; Set minimum Z

SPAX

@dc42 ok, I'll try

SPAX

@veti coz I print with 0.1 layer step
If I set 0.2, first layer (with 0.1 layer step) very poor and don't catch on bed....

Veti

no you adjust the offset of your probe in the M558 command not with M208

SPAX

Still not work!

I suspect you are getting inconsistent results from probing. Try replacing S7 on your final G30 command by S-1 so that it prints the errors without making corrections. Then run G32 several times and see how consistent the results are.

Also, we don't normally advise using 7-factor calibration unless the height map is a particular shape. 6-factor usually gives better results.

Those results show differences of around 0.02mm which isn't ideal, but not too bad. Try S6 instead of S7.

SPAX

@dc42
Did s6.
Now G32 repeats little good....

But before on 2.02 was be after 0.03-0.08(maybe because I did matte on my glass today)

Thank you. I will try to print something tomorrow....

Now better, but not ideal (((

Why this happening?
First layer poor....some place the nozzle touching the bed some plase have pit...
If I run G29 the nozzle starting print like on wave... and first layer much more poor .

dc42

@spax, what type of Z probe do you have on your delta printer?

After run G32 a few times, if you then run G29, what does the height map look like?

SPAX

@dc42, I use your IR probe.

I have 6mm aluminium plate + 0.5 heatsink pad + 4mm glass (back side painted in black).

SPAX

@dc42 any thoughts?

Phaedrux

Can you rerun the G29 heightmap with a piece of plain paper covering the bed surface? The idea being to eliminate any inconsistencies in the IR probe reading the surface.

dc42

Also please post a screen shot with the height map rotated so that we are looking along the X axis.

That height map looks terrible, as if you are probing off the edge of the bed or something like that.
