Hi! Hope you guys can help me out.
I have a 3018 CNC (banggood). Problem is that it makes the jobs mirrored and also flipped. The flipped thing is resolved by switching the outer 2 wire on the connecter
Cable for the motors. But, still mirrored and now the control is reversed.
I adjusted the $2=0 to 1,2 and 3 but no difference.
I have no idea how to fix this.
Hope someone can help me out.
Are you familiar with these?
$3 – Direction port invert, mask
This setting inverts the direction signal for each axis. By default, Grbl assumes that the axes move in a positive direction when the direction pin signal is low, and a negative direction when the pin is high. Often, axes don’t move this way with some machines. This setting will invert the direction pin signal for those axes that move the opposite way.
This invert mask setting works exactly like the step port invert mask and stores which axes to invert as bit flags. To configure this setting, you simply need to send the value for the axes you want to invert. Use the table above. For example, if want to invert the Y axis direction only, you’d send $3=2 to Grbl and the setting should now read $3=2 (dir port invert mask:00000010)
Thank you! $3 was what I needed to change! Played a bit with it and now it works great!
Many thanks again!
