Hello,
I’m new to this platform and also not very familiar with the Arduino software.
I did build a plotter to write and draw and everything is working perfect.
my only and big problem is that all my writings are 45° rotated.
this is because I use the GRBL code.
in this code: (on the bottom of this question)
you can see that every stepper motor has a pulse and direction.
the only problem is i’m not using X,Y,Z.
I need postieve X and negative Y to draw a straight line otherwise it’s shifted 45°
I tried adding up the bits from X and Y command by using 2,!3 for the steps or 2 && !3 but is doesn’t seem to work.
how can I set up this code so when the code drives the X axis the Y axis also rotates in the other direction? meaning driving step digital output 2 and 3 and direction puls 5 postieve and 6 negatieve.
the last one I might be able to skip because it’s a low.
so how to active two bits (2 outputs) with one command.
thnak you for you help.

#define STEP_PORT PORTD
#define X_STEP_BIT 2 // Uno Digital Pin 2
#define Y_STEP_BIT 3 // Uno Digital Pin 3
#define Z_STEP_BIT 4 // Uno Digital Pin 4
#define STEP_MASK ((1<<X_STEP_BIT)|(1<<Y_STEP_BIT)|(1<<Z_STEP_BIT)) // All step bits
// Define step direction output pins. NOTE: All direction pins must be on the same port.
