The y-axes do not rotate in the positive direction when cloned #168

Closed valeckUDL closed 3 years ago

valeckUDL commented 3 years ago

Hello I want to use a clone of the Y axis. I made edits to the config file and to the axis parameters. But the Y-axis motors rotate correctly only in the negative direction. When attempting to return in the positive direction, the motors are blocked. In addition, the X-axis motor is trying to turn. No alarm is displayed.

Hi @valeckUDL,

In your config.h, you must also change the number of linears axis: #define N_AXIS_LINEAR 4, since your 4th cloned axis is a linear axis.
Unfortunately, I think it's not this configuration detail that's causing your problem.

On the problem you describe, I see 2 possibilities:

In case of corruption of the EEPROM which stores the parameters of Grbl, the behavior can be completely unpredictable.
In this case, the Grbl command: $RST=* makes it possible to reset factory defaults and to find normal operation.

P.S. Your grbl-Mega-5X version is not up to date, the latest up to date version is: 1.1q.20210103.

I followed your recommendations. Including downloaded the latest firmware. It all worked. Thank you very much))
