Thank you both

I have a question about the min and max DRO's.  I put a set for X (OEM's 4 and 10), Y (OEM's 5 and 11) and Z (OEM's 6 and 12) on the main page of my Tormach screenset.

The DRO's don't reflect the actual motion extents of the loaded gcode file.  Is there anything special I need to do, or are the DRO's supposed to automatically parse the file and find the limits?  I couldn't find any documentation in the PDF's or Wiki, and this was the closest thread I could find.

Thanks,

Randy

Please attach your screenset.

It's at http://www.machsupport.com/forum/index.php?action=dlattach;topic=11968.0;attach=16166 already and the board won't let me upload another copy.

Thanks,

Randy

Randy,

    Once you "Load the G code" into Mach 3, the program extends will already show, NOTE it goes by the current work offset when you load the code.

Your screenset is working fine here and showing correctly when I load code. If you are still having issues can you post your xml so I can check with your settings.
Hood

Scott, then my setup is not working correctly.  When I load a new gcode, the mins and maxes are way off what I know are the extents of even the rawstock.  And the mins and maxes are generally the same number.

Hood, can I copy the XML while Mach is running?  It's doing a 4+ hour contouring job right now.

Thanks,

Randy

Shouldn't be a problem but probably best just to wait. I will check in the morning, or I should say I will check back later in the morning as its 01:40 here

try zeroíng all axis's and regenerate the the path. works for me. if x is at say +100 when i load the code and the code has an actual X- of 20 and a X+ of 20 mach will show it as being X-20min and X+120max

if you use arcs forget it. still not figured out how to get that working properly. i had to switch off softlimit because when i load arc codes my min and max on all the axis's can be as far out as 1200mm sometimes.. and i only cut jewellery

Hood, here's my XML.

Chris, I'll read about how to regen the toolpath.  I always start by touching the first tool in x, y, and z (in that order) on the rawstock so the tool does end up within the x-y machining envelope, but above in Z.  My toolpaths are usually a combination of lines and arcs.

Thanks,

Randy
