    Default HAAS mill stops feeding in the x axis

    I have a HAAS VF11 that stops feeding, the spindle is still spinning.
    It is like I'm using single block but it is not on.
    It's happing randomly not consistently yesterday it happened 3 times today it has already happened 5 times.
    This is only happing in the x axis going in the x- direction not in the x+ direction.
    I'm not using cutter comp.
    Thank you in advance.

    Here is the gcode

    Default Re: HAAS mill stops feeding in the x axis

    Probably missing decimal point in the feedrate. F30 without a decimal translates to F.03 if i recall.

    You are missing Feed moves after every G0 move you have G1 moves with no Feed rate, a Feed rate would have to be on every G1 move after the G0 has been used

    Default Re: HAAS mill stops feeding in the x axis

    No, feed rate would carry over from last call out, so that's not it. But with a feed rate of 3.4 you might think it stopped!

    Default Re: HAAS mill stops feeding in the x axis

    [QUOTE=dkcom;2325234]I have a HAAS VF11 that stops feeding, the spindle is still spinning.
    It is like I'm using single block but it is not on.
    It's happing randomly not consistently yesterday it happened 3 times today it has already happened 5 times.
    This is only happing in the x axis going in the x- direction not in the x+ direction.
    I'm not using cutter comp.

    i agree with machineit the feed rate is model and doesn't need to be on every G01 line

    which control do you have -the next gen or classic ?
    is it happening at the beginning of the move or is it during the cut ?
    is it random in the machine position or is it in the same spot each time ?
    was this programmed by hand or was a cam system used ?

    G0 call cancels the Feed rate G1 after a G0 requires a Feed Rate

    Standard practice how Modal works

    G0 X30 Y5 (G0 is effective in this block)
    N20 X50 Y10 (No G-code specified, G0 remains effective)
    N30 G1 X30 F200 (G1 is effective from this block, NOT G0)

    In some case the Feed does stay modal but not in all cases, he should try it and see if it solves his problem

    Another thing he could try is to reprogram not using any G0 moves and just use a G1 for all the moves as it looks like he is using G0 for a -Z move into the work

    His program is fine. He does NOT need to repeat the F3.4 at each G01. Also, he is feeding into the part (G1 Z-0.075 F3.4).

    From the Haas Operator manual:

    The feedrate value (F) can be on the current program line, or a previous line (the control will always
    use to most recent F value until another F value is commanded.
    G01 is a modal command, which means that it will stay in affect until canceled by a rapid command such as G00
    or a circular motion command like G02 or G03.

    From the Haas Operator manual:

    The feedrate value (F) can be on the current program line, or a previous line (the control will always
    use to most recent F value until another F value is commanded.
    G01 is a modal command, which means that it will stay in affect until canceled by a rapid command such as G00
    or a circular motion command like G02 or G03.
    I already post that, I ran his program through as well so may be his control is have a bad day, I would add the feed rate where he is having the problems and see if it works or not, his program did hang up but only at the end
