    Hey guys, I thought the machine was pretty good, setup wise, until I tried to do some small engraving (100x50mm) but turns out I have some issues!

    Can anyone point me in the right direction with this as to what the issue could be?
    All nuts and bolts are tight, no slop in any axis and slaved motors are spot on. I'm actually stumped

    Thanks Davek0975

    Apologies I should of made more clear what my issue was. As you can see the curves in the engraving are horrendous! Straight lines are amazing.

    The different thicknesses was me trying different depths

  4. Ok, flat portions on curves are generally caused by slop in one or more axes, maybe a loose pulley or worn belt (if any)

    An I've never checked the pulleys on the shaft! Will do that now

    Not used V-Carve so not sure of the options. Check to see if the arc are made up of straight segments or if they are real curves. It they are segments, then you there may be an option to smooth the curve. This replaces the straight lines with curves that make the program run better.

    Failing that it may be mechanical.

    Best of luck

    Cheers I will take a look. Mechanical wise everything's looking solid. Could it be a backlash problem? I had measured it but it was fine
