    For sure. I've only done the Y beams and there's a noticeable difference in cut quality between X and Y. After doing the Y, I measured the flex in the Y beams before and after adding the supports. Before it was .017", now its .002". The X beam will get 2 rails since I cant add supports.

    Also if you stop defining curves as bezier Vcarve should output the G-code for arcs. (you are using the correct post processor)

    Ok will do.
    I haven’t noticed a difference in the cut quality between the two so I’ll stick to the circular arcs in vcarve. Glad I’m using the correct p/p.

    i tossed the G-code you posted into UGS and it looks like nice smooth curves to me.
    Post your $$ settings from your xPro. This is belted? 20tooth? did you dual belt ?
    Cheers

    I’m glad is smooth on your end that confirms it’s a machine issue or setting issue.
    I’ll have to get the settings tomorrow at the shop.

    Dual belting will get you big benefits for cheap with 1500-3000mm belts. Just make sure to do it correctly :)

    Next time, easier to copy/paste from the Serial Console tab (;
    Go to Serial Console
    At the bottom, send $$
    Select and Copy from the terminal above the input box

    Hi Phoenix, your speeds and accelerations are a bit aggressive and can lead to the step-loss and chatter, try 5000mm/min max speed and 500mm/s^2 acceleration (1500mm/min should be fine on Z)
    Cheers
