Um2 need help changing configuration.h

[micheld1984 0]

Hello all.

 

My sister and i are not that much of programmers. We get the basics a bit.

we have changed the feeder of our ultimaker 2 extended. This we have done because of the many retractions we have in our prints.

The new feeder is a sanjui feeder.

 

therefor we heard we need to change the configuration.h default steps per unit to another number.

This is because the reduction on the feeder. 

 

After 10 hours of searching and uploading firmware versions to the printer we are very very stuck.

 

Every time we fail we could fix it by doin a automaticly firmware update in cura.

 

How to change just a number in the configuration.h?

We think we need to manually update in cura. But therefor we need the correct version.

 

can someone help us.

 

thank you very much in advance

 

greetings Michel and Marja

I strongly recommend you get tinkerMarlin here:

https://github.com/TinkerGnome/Ultimaker2Marlin/releases

 

Once installed you can change the steps/mm (and even direction) in among the menus - I think under motion settings.  

 

 

Alternatively you could read this long post - building Marlin has a lot of steps that con sometimes be confusing:

Thank you a lor gr5

 

this night i was finally able to change the configuration.h file.

sadly this topic wasn't approved by moderator and i could not change the topic.

But more problems came when the feeder motor was turning the wrong way.

Idiot me just turned around the sanjiu feeder but when all finally worked i noticed the

teeth of the feeder where upside down. stupid stupid :D:P

 

So tinkerMarlin is the way to go

 

We will try and read the post tonight.

 

ANd we thank you again. I love it that the people in these community's help each other. 

We have multiple ultimakers working here and hope we could help someone else sometime.
