    Default Work is Mirrored???

    Hi Switcher or any other suitably clued in Zoners

    I bought Vectric Aspire and nearly everything is perfect except for 1 thing. I draw everything in AlphaCam with the origin 0,0 to the bottom left and send to the machine and the preview in Xilog (pp) shows as it was drawn. Aspire files appear in the preview mirrored from bottom to top in so far as the origin is top left. I cant show visuals to clients as they are back to front. What I have to do is draw the item to be machined as normal and mirror it before I attach toolpaths so it comes out in the right orientation when its cut.
    I've put this prob to Vectric staff without avail. I've also annoyed people in the 5 continents. I think its a change needed to my post see attached.

    Thanks
    Mick

    Do you have bottom left as the origin in Aspire?

    keelhauled,

    Looks like you have a bunch of machine specific code?

    I might be wrong, but it looks like the header is sending the machine to the Max. size of the material in both X & Y, instead of X=0.0, Y=0.0

    +---------------------------------------------------
    + Commands output at the start of the file
    +---------------------------------------------------

    begin HEADER

    "H DX[XMAX] DY[YMAX] DZ[ZLENGTH] -A R1 *MM /DEF V10 BZ=25"



    ***************************************************
    ***************************************************



    I noticed all the other header files (Mach3, etc...) in Aspire all include a variable like

    VAR X_HOME_POSITION = [XH|A|X|1.4]
    VAR Y_HOME_POSITION = [YH|A|Y|1.4]
    VAR Z_HOME_POSITION = [ZH|A|Z|1.4]

    The way I read most of the other PP is, XH , YH , ZH , are all calling Home positions in the Aspire program.

    "[N][XH][YH][F]"

    Switcher, a lot of large commercial woodworking machines have the part size in the g-code file header. This may be the same thing.

    That's cool.

    It's a lot easier to work on a post when you can work on the actual machine (trial & error).

    Thanks for the swift response lads, that gives me some insight to play around with today, I'll update later. Yeah Ger I'm using bottom left as origin in Aspire. The first time I came across this whole problem I thought 'Ahh this is an easy fix just use top left as my origin' but what this does is puts the piece into space outside the parameters of the machine and does not cure the fact that the piece is mirrored. This brings me to your observation Switcher, I think the XMAX and YMAX are related to the size of the piece as if I try to run a prog bigger than the size of the bed I get a limit switch message to say go back and edit a certain parameter.

    Thanks Again
    Mick

    Update1: For sure the XMAX and YMAX are sheet sizes
