I need a fonctional Marlin

I built a coreXY printer controlled by Marlin-1.1.8 and
pronterface or repetierHost.
I've been struggling for days to find the solution to problems that keep me going in circles.
I would like to have a configuration.h that works in order to adapt it to my machine

what is your problem?
I would start by recommending you upgrade to at least Marlin 2.0 = it is released. I am running the 2.0.x bug fix because IMHO it has a couple important fixes (at least for me).
My CoreXY machine is home built modded from Carl Fenick's plans. Working very well right now.

My config files won't do you any good with 1.1.8.
Tell me what hardware you have and what problems you have and I will see if I can help. In the mean time, download the 2.0.x bugfix.
I just downloaded b7f8163 = tell me which one you get.

To keep yourself sane with Marlin and its updates, I suggest creating a working Marlin folder = mine is "Marlin top".
That way you have separate folders for each update you do.

Download dnld the build zip file to that folder. Then:

1. Add the build number to the downloaded zip file.
2. Unzip the file. The folder will have the filename.
3. Do a verify compile to be sure you are working with a good copy
4. If you have a commercial printer, look in the examples folder for suggested configs and copy them to the Marlin folder.
5. If there are no examples for your printer, copy the config files from Marlin to the config folder for backup b4 you start modifying.

I have also set up a BAT file to delete unneeded files & folders just to keep my head clear.
Let the mods begin.

Hi,
My problem is a wrong Z axis dimension.
Instead of printing a height of 20mm it prints a height of 8.50!? ...
X and Y are correct

This is default

/**
* Default Axis Steps Per Unit (steps/mm)
* Override with M92
* X, Y, Z, E0 [, E1[, E2...]]
*/
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 4000, 500 }
================

this is mine

#define DEFAULT_AXIS_STEPS_PER_UNIT { 200, 200, 800, 185.2 }

your answer indicates you may not be capable of fixing this yourself, since you did not give me the other info to work with that I asked for and apparently do not want to follow my upgrade suggestions. 3D printing is not plug and play. If you do not have observation, troubleshooting, and logic skills, you will never be able to fix the issues associated with bad prints.

Thank you ruggb

I resolved the dimension issues #define DEFAULT_AXIS_STEPS_PER_UNIT {180.5,180.5,960,92.599318}
#define DEFAULT_MAX_FEEDRATE {500, 500.75, 25}

But now I have walls that barely hold together and look like coarse lace full of holes. I think to act on the extrusion speed by increasing DEFAULT_MAX_FEEDRATE and / or DEFAULT_AXIS_STEPS_PER_UNIT

temperature

speed, temperature, steps/mm, Z0 setting.

They can vary based on the characteristics of the print. They do vary on the type of filament = mostly temperature.

You need to step back and do some studying. As I told you it isn't plug and play.

Revue some sites on solving print problems. There are a lot of them now.

You seem to have no concept based on what little info you have posted so far.

It is true that I do not have much experience but I am learning. I understand that everything is based on the parameters specific to each machine.
Also I have adjusted for each axis speed, steps / mm, heat of more or less empirically to finally settle the last problem which was a problem
of speed of movement and steps / mm of the extruder.
Now everything is set
Thanks for your intervention.

good luck to you.
watch your prints printing. You can use those observations to learn a lot.
When you have a problem, post what you observe.
We hate posts that say "My printer doesn't work. What's wrong?"

There is plenty of info on the web. Learn to search for it.
