@o_lampe said in 2nd print too high and z-offset is inconsistent,config problem?:

I also repeat the G31 line everytime I change M558. I'm afraid it'll use default values instead, if I don't. (paranoid?)

Definitely paranoid. The G31 restatement is unneeded.

@cosmowave said in 2nd print too high and z-offset is inconsistent,config problem?:

your end code is not really nice if you print an object near zmax! So the z axle can't raise 5mm.
It moves the z axle 5mm if it is possible.
If not, it moves to zmax.

Also unnecessary. If the axis limits are set correctly, the firmware won't allow it to go beyond z max anyway, so a relative move close to the z limit would stop at zmax regardless. No need for conditional gcode there.

@lui2004 Did you end up figuring out your problem with the second print start?

@lui2004 - OK let's say, we can eliminate the nozzle. 😀
Try to dry the filament. Even if it's new, it doesn't always mean it's dry.

@lui2004 in the end gcode you can add a move to lift slightly and move the tool out the way.

E,g,

G91 ; set to relative positioning G1 Z5 ; raise Z 5 mm G90 ; set to absolute positioning G1 X0 Y0 ; park at X0 Y0

@lui2004 the prusa calculator is good, and there is also a calculator build into our config tool when you set the steps/mm

@lui2004 Then you need to increase the retraction (S) and increase the feedrate (F) if needed. It appears the 0.80 retraction isn't enough.

@lui2004 Ah, sorry, I misunderstood. Contact Precision Piezo. According to this page https://www.precisionpiezo.co.uk/product-page/precision-piezo-orion-kit

Hotend clamps for E3D Chimera/Cyclops and Microswiss hotend under development.

hi
s3d doesn't support Firmware Retract (maybe in 2050 when V5 will release 😉 ) but for now this thread : https://forum.duet3d.com/topic/389/setting-firmware-retraction-with-simplify3d-slicer can help you

As phaedrux says you're to close to the bed move your nozzle some babysteps higher

@lui2004

Left , front is 0, 0 , right / back and fully homed should be 235 , 235 ,
Did my macro go right and back towards the X and Y homing switches ?

IMPORTANT have you a Ender 5 ( not pro or plus )

a few change to the homing file , but it is now much easier to set up , now you don't have a bltouch but a switch for z axis .

@lui2004

a little bit maybe from my personal observations regarding the new heater tuning algorithm:

We have here a small anycubic-i3-mega that got as new mainboard the duet-pcb, it sits in a wooden chamber with the standard heatplate used as chamber heater and 1 additional fan in the top of that chamber to "cool" the chamber by sucking out air (there are some holes in the bottom plate of the chamber to let new air in when that happens)

When using the new heater tuning algorithm, I leave the door of the chamber open and put the fan of the chamber to max rpm, BECAUSE first I did it the other way round with door closed and chamberfan off and after tuning and saving the tune with M500 I got a heater fault manually heating up, because that time the door was open and the fan on and that was too much for the state it was tuned in (heating too slow/temperature rise too slow).

So long story short: I would recommendate from my observations that you tune with "hardest" surrounding conditions for the heater. With hardest what I mean is, that it has to work hardest. If you tune it with the easiest condition, you might later get a sporadic heater fault when conditions get harder.

(I do not know if that on the long run could be also constrained by something like this request here https://forum.duet3d.com/topic/20844/limiting-ramp-rate-in-heating-algorithm/3?_=1610360187720 but for the moment I can work with it and that is what counts.)

i will say THANK YOU to @Phaedrux @Veti for your patience with me to solve my problems 👍 👍

i have learn a lot about 3D and RepRap👍

i think the post can be mark as solved 😊

@lui2004
what material are you printing that requires that?

@lui2004

G30 P0 X28.8 Y24 Z-99999 ; hinten rechts G30 P1 X198.8 Y24 Z-99999 ; hinten links G30 P2 X198 Y194 Z-99999 ; vorne links G30 P3 X28.8 Y194 Z-99999 S4 ; vorne rechts and report adjustments needed

You missed P1 🙂

Pulling my hair out a bit. I've started a post here that may be useful as you progress.

bedlevel_nozzle_0.4_200x200-0.3-0.8.stl

Here's a good first layer test pattern.

Try it once with G29 S1 enabled, and once without.

yes have changed it all,works fine.

Only extruder motor is hot if print i dont know why.

Hi

the noise from the motors seems like rustle

Personally, I kept the metal case. Extended the opening for the SD-Card slot, moved the PSU by drilling some new screw holes and added a PCB holder to attach the Duet Wifi board.

A 4 point mesh will always be flat as the controller connects the 4 points with straight lines. It does not represent the true shape of the bed.
I would be VERY happy with a bed as flat as the one shown with 36 points !!!
