Hi,
I'm a little afraid, I probably should to calibrate my printer I3 pro B. But in the firmware topic there is to much or not enough informations...
Which firmware should I use :
Marlin? Ramps? Sanguin ? 3d touch...?

Should I check my threaded rod and modify the source code? How to know my rod...

Should I send a gcode to the printer at the end? And how?

Should I use Marlin 2.0???

There is to many questions to be confident...

Hi, Is there something wrong with your firmware?

If you upload the firmware,
You can download it on the official website: https://www.geeetech.com/download.html?download_id=34

Then you can refer to this for uploading: viewtopic.php?f=20&t=69684

Thank you.

I had to change the power of the motor specially for z axis...
So I am trying my first printing with the calibration cube and I find some adjustments to do...
And also I have to understand why the printer has some difficulty to finish like the extruder don't have the strength to pull the plastic...
