    First big print from a 16A Prototype

    Printed on a Hyrel 3D Model 16A prototype at 3000 mm/min:

    or 50mm/s for everyone else :-)

    Math is hard.

    lol - why would you use mm per minute. ?
    Almost impossible to estimate the actual speed. Whereas mm per second. Everyone can look at a ruler and work out how fast something travels in a second.

    What's the red dot in the new machine videos ?

    Because every gcode file that I've ever seen specifies the linear feed rate in mm/min:

    G1 X134.898 Y125.559 F1500.000 ; move to first perimeter point
    G1 X134.678 Y125.367 E134.06120 F1500.000 ; perimeter
    G1 X134.434 Y125.228 E134.07645 ; perimeter
    G1 X133.641 Y124.383 E134.13941 ; perimeter
    G1 X133.437 Y124.052 E134.16051 ; perimeter
    Does your experience differ? Please share. Maybe it's just our firmware flavo(u)r that uses mm/min.

    That's a positioning light, so you can see what area your work will occupy.

    all slicers have a choice of mm per minute and mm per second.
    I have no idea why anyone would want mm per min for print speed.

    For filament feedrate maybe, but print speed ? makes no sense.

    How about that. I've never noticed an option. I don't doubt it's there, though. Maybe I'll look tomorrow.
