GRBL-28byj-48 Plotter problem on X axis - Solved #13

Closed MDS67 closed 3 years ago

MDS67 commented 3 years ago

The X axis is working incorrectly, when moving slow, loses steps, and some times stop moving.

On this case, designing a circle, and the result final is not a circle...

Everithing is loose, changed motor and controller and same thing, so I think it's the firmware of the arduino.

Using: Firmware: https://github.com/TGit-Tech/GRBL-28b... Gcode generator: http://jscut.org/jscut.html

I uploaded a vídeo to youtube: https://youtu.be/Zw0NLsuF52A

And attached a zip with the gcode for the circle used on the vídeo

circle.zip

SOLVED: I found out that the pins to the arduino were swaped... i followed a diagram on the internet and it is wrong. Manuel.
