    Just watched your electronics setup, great job on the video..
    Couple tips;
    Micro-steps - don't use the max, you only want to use the most that you need to achieve smooth motion and the resolution you need.
    at 1600 you will have 1600 steps (per motor turn) / 8mm (lead) = 200 steps per mm, or 0.005mm of movement per step..
    More micro-steps than you need reduces holding torque somewhat, and max stepper rpm (for fast rapid movements) due to Arduino frequency limitations.

    Don't forget to set your GRBL settings to match your micro-steps- steps per mm setting, $100, $101, $102

    Wires - not sure if you have all the wire yet, but use as much shielded wire for stepper connection, limit switches and hook up the drain of the shields to a earth ground.
    The spindle VFD and stepper drivers make EMI noise that can cause com issues.

    Great job, looking forward to seeing what you make with the machine!
    Cheers
    Gary

    Thanks for the feedback so far, I'm actually using 1600 atm. Did a bit of research, thanks for the data.
    Thanks for the settings tip, I didn't know about that yet.

    Yea the wire situation is absolutely horrible, I'm currently working on limit switches and they get triggered randomly.
    I already ordered shielded wires. I'll keep updating the build.

    Best regards,
    Chris
