Distance between the extruder and the base - Z axis

Hello!

when the 3D Printing begin printing, automatically
the distance between the extruder and the base increases considerably! (About 10cm!)

Initially approached the extruder at the base, then when Printing the Z axis rises considerably,
and when the plastic falls is not positioned correctly.

How i can fix this problem?

Really thank you,

Fabio

Hi,

someone can answer please???

thanks,
Fabio

This is hard to answer.
10cm? 100mm?
What software are you using?
Have you downloaded and installed this one?

Have you changed the firmware?
Is this a new build or was it working properly?

Hi!!

First, thank you for the answer!

Yes, the extruder increase the distance from the base about 10cm when start print!

The software is Repetier Host, last version, the firmware is updated!
I want show you a photo (I have a photo of the problem on my smartphone) but i have no url to attach the picture

There are some type of reset o some test that i can try with the maschine???

Thanks!

Fabio

Try downloading and installing this version.
It is older but already has the ini files and the drivers (since you have the drivers installed you can skip that part) installed in it. This would be a good starting point.

Okkey!!! I will try… Thank you for all!!

I’ll let you know soon!

Hi,

I try to install the version of Repetier Host that you attach me…nothing!
I try to update the firmware…installed the firmware: firmware_k8200_v2.1.1 (marlin) but the situation is the same.

The distance between the extruder and the printing plate initially is ok.
But when start to print the distance increase about 10 centimeters.

Also every time I click on the " home button" of the ’ axis z the z axis Increases.
How configure the Z axis in right mode?

There is a solution???

That sounds like you have incorrectly wired the Z endstop.
Then the printer thinks it has hit the endstop all the Time and constantly moves up.
Check if you connected the correct pins of the endstop.
The circuit should be closed when the endstop ist free and open when the endstop is hit.

HI!

I watch the circuit but nothing! The problem persists.

it’s possible send the 3D printer in belgium for a total control???

In this state there are nothing that i can do for fix the problem.

Thanks!

Fabio

HI!!!

Sorry, but it’really important!!!

Can you tell me how send the printer in Belgium please!!!

Thanks

Fabio

Hi,

I’m not sure they will accept the complete printer (but I don’t know).
I’m wondering what happens when you home the print head
Does that work correctly?
After you home it and tell it to move the Z axis up 10 mm does it do that correctly?
Did you slice the project or are you using someone else Gcode?

Hi!
Yes, when i tell it to move 10mm up, does it do that correctly!!!

The distance increase from the base, everytime i click the home button,
the Z axsis move up 10mm. initially is 0, then is 10mm, then is 20mm…etc…

But when the K8200 starts Printing…automatically the distance from the base(plate) increase and…it’s too big!!!

When the plastic falls does not follow the correct print sequence because the distance from the plate it is to big!

I slice the project not use someone else code, i use the version of the software that you attach me (k8200.eu/downloads/files/dow … _0_95f.zip)
but nothing!

But this printer 2 months ago work perfectly!!! with the same software setting…i think that is an hardware problem.
I’m not a specialist and for this i need to know of send the printer in Belgium

Thanks!!

Fabio

Like I said I don’t think you can send the complete printer.
You should just send the control board.
I did find this link http://support.velleman.eu

Hi!!!

Okey thank you!!!

so, i need to open a NEW TICKET rights??

Fabio

This sounds like the start code of cura (old version?). It will go down to the print bed, prime, rapidly lift the nozzle , then move down to the start of the print. The problem is that it tries to lifts way too fast, and Z axis can not keep up. It will sound horriby, and then the nozzle will crash in to the bed because the head is lower than the firmware expects.

You need to change to start gcode or limit the Z axis speed in the firmware. I dont recall how to do that, but Im sure someone else can tell you.

Since he is using the custom version of Repetier for the K8200 the slicer should be Slic3r.

Can you please post the first 20 lines of g-code the slicer generates?
Maybe there is an issue with that.
