    Totally agree, I just assumed the OP wants it to rewind and have to press cycle start.

    I would replace the M2 with M30 and get rid of the M99. The M99 is likely causing an endless loop.

    There are plenty of optional stops in there :willy_nilly:

    Post your code. Sounds to me like the program is still "open" and can't be opened again. Are you using M30? M2? Is there an old program in the machine you can look at to see what it wants for code?

    That is the attitude that I would want to see! We all have to stop and think sometimes, its the people that don't that tend to have the most problems and crashes.

    I'll third homing the machine, or do they have some weird procedure like cold start on a Fadal? Could the clunking be backlash comp? No telling what the previous guy messed with.

    Just speculation but it sounds like something is moving around (work, tool, spindle, table...) and causing the cutter to grab a big bite and chip. It's kind of tough to chip a cutter in...

    I would hardly call using sand an amateur method. Less than ideal yes, but so is anything short of mandrel bending in the OP's situation. I was simply following the repair procedures laid by Babcock...

    Buy a Hypertherm, end of story. Theit machines are tested to some ridiculous standard and a 60% duty cycle machine will easily run non stop on a table.

    No its not but if the chuck closes down small enough to hold the part then what is the point? It's a one off repair type job. My first lathe didn't have a quick change nose so I had a 14" 4 jaw on it...

    I could be off but I was under the impression the whole idea was to transfer vibration out of the machine. Hence why large rotating equipment often has concrete pillars all the way down to bedrock.

    That would put you around a 5.5:1 diameter to CLR ratio. The OP is trying to achieve 3.25:1 That is a huge difference and I just don't see it happening without a mandrel

    It sounds like you are not doing very thick work. Spray transfer is nice cause of the reduced spatter and increased penetration. I would suggest setting up with 0.023" wire for spray transfer based...
