    Red face First homemade CNC Running GRBL on Arduino - Problem with settings

    The machine has two HY-DIV268N-5A drivers for the x and z axsis and 2 DMA860H drivers for the y-axsis. The settings for the drivers are all at half step. That is for the HY-DIV268N-5A drivers the switches are set at "1. off 2. on 3. off 4. on 5. off 6. on" and for the DMA860H are "1. on 2. on 3. off 4. on 5. on 6. on 7. on"

    My calculations for the motors are:

    y-axsis (Pitch of 10 motors 1.8') - 200steps/10 x 1/2= 40 which gives me the code $101=40

    x-axsis (Pitch of 5 motor 1.8') - 200 steps/5 x 1/2 = 80 which gives me the code $100=80

    z-axsis ( pitch is 8 motor 1.8') - 200 steps/8mm x 1/2 = 50 which gives me the code $102=50

    It seems that I have made a mistake as the drill location on my program does not match the drill location on my material.

    I will upload a photo of the shape I am trying to cut and you will be able to see the the drill veers left and leaves my block of foam. I will also upload the G-code.

    I have been screatching my head for two days now and I would be really greatful if anyone has any advice. I will upload the g-code and some photos. Thank you so much for sharing your time and experience with a begginner like me.
