Calibrate z ! and first layer !  

Re: Calibrate z ! and first layer !

Your PINDA sensor is too high and must be lowered. Check that there is 1 mm level difference between the nozzle and the PINDA sensor. Then make a new XYZ calibration. Also, make sure that you have completely assembled your new Hotend according to the manual.

Edit.
Is it a Selftest" that you show on the video? If so, the steel sheet must be mounted.
You might have chosen the wrong menu and that it was a "Calibrate XYZ" that you wanted to run? It should be run without mounted steel sheet.

thanks for replay..

Your PINDA sensor is too high and must be lowered. Check that there is 1 mm level difference between the nozzle and the PINDA sensor. Then make a new XYZ calibration. i do it and still very thin with adjustment z to 100 🙁
Also, make sure that you have completely assembled your new Hotend according to the manual.
can you explained please I bought this is it need any editing?

i know that i should to remove steel sheet from heatbed with Calibrate XYZ

thanks again

Re: Calibrate z ! and first layer !

What I meant was that the video showed that you run a "Selftest" without the steel plate being mounted and that is why the nozzle crashed into the bed.
Selftest should always be run with mounted steel plate so that the PINDA sensor can detect the correct height for the nozzle.

If you have managed to do an XYZ calibration (not Selftest), you should then do a "First layer calibration" where you adjust the correct Z level.

Re: Calibrate z ! and first layer !

hi again
i returned a self test with sheet this is a result ( https://drive.google.com/open?id=1ZnGJS9ZSVYx5RhsJKt_xExgEa3KXuXTL )

and here a long video from calibration XYZ
i hope you can find any thing ( https://streamable.com/frrew )

first layer cal adjustment z 100 ( https://streamable.com/wto30 )
next adjustment z 492() https://streamable.com/exjce
then adjusment z 1000 () https://streamable.com/czs4t hear the sound
this is a final result https://drive.google.com/open?id=18XUkuCUhaROABS-WyxN8oCSvjmhXF3z1

thanks a lot

Re: Calibrate z ! and first layer !

It was nice that you have started calibrating.
Now, just find the right Z level, which may take some time.

Keep in mind that the difference between -1000, -492 and -100 is enormously high.
When doing the Z-level fine tuning, this should be done in very small steps.
The difference between a good first layer and a worse can be as small as -505 (good), -507 (better), -510 (best).

But first, you do a rough calibration so that you find approximately the right level, then you do the fine calibration.

If you place two office paper (2 paper = 0.2 mm) between the bed and the print head, it is the correct height when the nozzle just starts scratching the paper.

hi again
i do like what you want me to do and unfortunately it doesn't works

here is the video https://drive.google.com/open?id=1x1WmS0W1ZhgopPA_VOgqjyD9OCmADb7R

you can see there is no filament on the bed ... it doesn't make sense i don't reducing ....

i think there is a problem with filament or tube of them

by the way i unloading the filament and preheat it to ABC (255/100) and see some filament go out and repeated the process. also clean the nozzle, bed it doesn't works .
filament type PLA 1.75

where is the wrong ???

Re: Calibrate z ! and first layer !

Mine did that too. Two problems. Clearly you're getting stringing and the filament isn't sticking to the sheet. Start by washing the sheet with dish soap and water, rinse it off with water and let it dry. Hopefully the filament will stick after that.

Re: Calibrate z ! and first layer !

Thanks for responding
But I am already clean it with acetone 🙁

Re: Calibrate z ! and first layer !

You need to lower the nozzle more. The values I wrote -510 was just an example, not yours Z level. Your Z level is probably between -600 and -700.
You must adjust the Z level until you get a good first layer.

Re: Calibrate z ! and first layer !

Yeah I know you just said -510 for example.
I am trying from two weeks.. and i used a machine very well on july. I don’t know what’s happend ... so I said that i thing there is a problem with filament or tube of them. Because I choose number without changing and the filament started very will and on the middle there is no filament at all.

Re: Calibrate z ! and first layer !

Hi there
My problem it doesn’t solve.
Update

I see the flowing of filament is very thin .. any idea?
