Printer's axis moving in the same way

General Discussion

Hi everyone!

I’m making printer, using mainsail and x and y axis are moving in the same directions. For example: when i want to move +5 in the x and +5 in the y, it’s going in the same way. Same with negative directions. What should be the problem and how can i fix it?

Hello!

  1. Please attach the klippy.log to you next post. It was asked for.
  2. What kind of printer do you want to build (kinematics)?

First of all, thanks for response!

This my klippy.lo and this is my printer.cfg.

I’m using core xy. Also, in my project, i only need x and y axis, i’m not using z axis.

Could you post some pictures of your design, especially include the belt paths.

I had a similar problem with one of my CoreXY printers that was due to me having one stepper facing up and one facing down. You might want to try negating (putting the “!” character before the IO pin) in the X or Y stepper “DIR” pin definition.

I try all different cases with the “!” in the X and Y stepper’s “DIR” pin, but it does the same. It only goes in 2 direction: down and left (from motors view)

Thank you very much, now it works.

The problem was, that one of the tmc “DIR” pin’s jumper was out.
