    ok so I can now ref home and Z references first then Y and finally X, all seems as it should be to me.
    New problem, I jog to work piece, home at the cutting position and regen toolpath,thats right ? yes?
    then machine tries to cut through to china! and to top it all off after I reset and checked my settings , hit start , and in stopped saying limit switch activated and keeps on cutting out after reset (which is accepted) immediately I hit start!
    Seriously is there a simpler alternative to Mach3?

    Have you set it to mm in Mach post the top 30 lines of your gcode.. I take it when you make a Z move to cut it does a -Z move and not a +Z There is nothing wrong with Mach it just need to be set up correctly then you will be fine.

    Set all axis how tutorial vids from mach 3 on youtube advise, ie z homes to top(I think that is - is it not,therefore it cuts to + ?)

    Tony I have sent you a PM.

    What CAM program have you used? according to the gcode the max Z is only 0.1mm deep and about 4 x 3mm in size. Is this what you intended?
    .
    Have you done the WORK Z zero on the bed or on the top of the part?
    .
    Edit: I notice that you have a G43H5 tool length compensation at the top of the gcode that will add to the depth of the tool.
    .
    Is this gcode been copied from the top as there is no initiation string there.!!! With a G21 etc in it.

    This is the tutorial fille roadrunner.tap that comes with mach 3 ,I have yet to buy cam software, but was going to go with cut 2D .I did zero on top of the part but didn't reilize it was that small! Is ther some way to scale it up? Or is that the province of cam software?

    I have a feeling that the road runner is imperial so you would need to add a G20 on a separate line at the top of the code. I think your prob is the G43H5 and you do need the string at the top of the code see below.
