I have changed my E5Pro from a generic corexy setup to Mercury, I finished my build yesterday and the only difference from my previous setup is that I now use Orbiter 2 and bigger steppers on X-Y. (old setup had Microswiss DD)
I Cant seem to figure out why my prints starts like this. I have set the Rotation_distance in klipper.

Maybe because the Z offset is too high?

stark sluice
#

I have set and checked the offset, should be correct

crimson fulcrum
#

I would double check it doesn't seem right

#

also make sure that z moves how much you ask it to

#

confirm rotation distance for z

stark sluice
#

I have dobble checked and set the offset again, i also ran some cleaning filament through the hotend.

#

I have not changed anything from my previous setup, except bigger x y steppers and extruder. Same config on everything else from my generic core xy setup. rotation distance on z is unchanged and should be correct.

#

Just noticed the priming line, ???? First time I have seen this..

crimson fulcrum
#

yup to high

#

using mesh right?

stark sluice
#

yes

crimson fulcrum
#

did you set zero_reference_position

stark sluice
#

no, I have not.

crimson fulcrum
#

try it

#

I had issues without it

stark sluice
#

I have never set this before. I'm searching klipper for info now.

stark sluice
#

yes i have always used the paper test

#

Trying to set zero_ref but confused how I find what coordinates I should use and I get this error "Option 'zero_reference_position' is not valid in section 'bed_mesh'"

stark sluice
#

I have tried to set Z offset multiple times now and I still get wavy lines on the prime line. The print is sticking really good to the plate, but still looks the same as before.

#

I'll assume you don't have z calibration but center should work fine as well

stark sluice
#

I'm using a CR touch if this is what you mean with "z calibration". The klipper documentation sais to use "zero_reference_position" but this is ignored by my machine for some reason and I cant continue before I comment the out the line "zero_reference_position: 113.0, 125.0"

I'm having trouble accepting that this is a Z offset issue, should I try to change back to my old steppers or something ? As I have said: I have been running a generic CoreXY with no problem for a long time, and the config for this setup and Merc should be the same. The only changes is the Steppers on XY and extruder.

#

Also when I extrude filament with klipper everything sounds normal, but when i start printing the Orbiter makes a loud buzzing sound when extruding and retracting.

#

by z calibration I mean this https://github.com/protoloft/klipper_z_calibration it's something else

Other than a z offset issue I can't really see any other possibility
you might want to try relative_reference_index if you're not on the latest klipper version that was the old (now deprecated) setting

can you also share a screenshot of your mesh?

Using OctoKlipper 0.3.9.5, Updated Feb 27

#

that is a klipper plugin not octoprint

#

cr touch is not very friendly with it

#

as you need an endstop where the nozzle and probe can reach

#

don't mess with it until you feel comfortable

stark sluice
#

ohh, ok. I removed the Z endstop when I got the CR touch

stark sluice
#

Question: The Stepperonline steppers needed to be rewired for them to work on the SKR mini E3V3, can it be that my problem is the LDO extruder motor and I need to rewire it also ??
Even if my z offset has been to large before I never experienced jagged lines like this.

#

No, wiring is correct acording to BTT and LDO. 😄

I still believe that the problem is you are printing too high, whatever the cause is. I would lower the z offset during a test print until the first layer looks correct 🤷‍♂️

stark sluice
#

I have no idea why the prime line is still jagged. But I have noticed that prime line is printed with close to correct Z offset but when it moves to the center to start the print it changes the offset and is printing to high.
I have set the offset "with paper test" so many times now but it will not stick and I set it so close that the paper is close to locked under the nozzle, it still prints to high.?

#

Can my CR Touch be the problem? or can it be a config/software issue.

devout niche
#

the probing looks good imho, i just think you'll need to print and adjust the offset some more 🤷‍♂️

#

can you post the sound?

stark sluice
devout niche
#

no that's not normal ^^"

#

is it the extruder though? I think the scratching noise is only when printing the back and the right side

#

but no clue, never heard that before

stark sluice
#

ok, just made me wounder because there is no sound when just extruding.
