A lower-left X-Y origin makes much more sense. When positive Y points "down", even things like the start angle for a bolt circle are upside-down. <br /><br />So last night, after I posted my comment, I went back to my machine, and into the TouchDRO setup, and changed the polarity of the Y axis. Now, the X-Y origin is the lower-left corner, zero degrees is "up" towards the column, and it all makes sense. The one discrepancy is that the numbers on the Y-axis handwheel are now "backwards", but I won't be looking at those anymore anyway. :-)<br /><br />By the way, I just discovered the "midpoint" (1/2) function on the X and Y axes. I wasn't aware there was that sub-menu you get to by pressing the X/Y value. Very useful!<br /><br />Thanks, Yurij!<br /><br />Walter Winnipeghttps://www.blogger.com/profile/14452760622362241659noreply@blogger.comtag:blogger.com,1999:blog-4429789698339059066.post-79792450082126911672021-03-08T22:37:20.725-08:002021-03-08T22:37:20.725-08:00Walter,

On most, if not all, vertical mills x0,y0 is in the lower left corner of the workpiece and z0 is at the "bottom". <br />That doesn't mean that you can't set up your machine to any coordinate system that works for you, but some functionality will be backwards (workspace preview, for example). In the long run, though, this might bite you, since it will be become your muscle memory and will be hard to unlearn.<br />Yuriy<br />Yuriyhttps://www.blogger.com/profile/11394499166280606198noreply@blogger.comtag:blogger.com,1999:blog-4429789698339059066.post-90442885969404132942021-03-08T22:02:16.666-08:002021-03-08T22:02:16.666-08:00I have a Sieg X1 "Micro Mill", on which ...I have a Sieg X1 "Micro Mill", on which I have installed iGaging scales on all three axes. I'm also using TouchDRO (a truly amazing system!). <br /><br />On my machine, when I turn the X-axis handwheel clockwise, the table moves to the left, and the numbers on the handwheel dial increase. On TouchDRO, the readout for the X position is also increasing. So, moving in the positive X direction corresponds to:<br /> - turning the X -axis handwheel clockwise.<br /> - moving the table and workpiece to the left<br /> - as seen relative to the workpiece, the tool is moving to the right.<br /><br />When I turn the Y-axis handwheel clockwise, the table moves "away", and the numbers on the handwheel dial increase. On TouchDRO, the readout for the Y position is also increasing. So, moving in the positive Y direction corresponds to:<br /> - turning the Y-axis handwheel clockwise.<br /> - moving the table and workpiece up/away<br /> - as seen relative to the workpiece, the tool is moving "down", towards the user.<br /><br />Based on these directions/polarities, it means the 0,0 origin could be set at the upper left corner of the table/workpiece. Positive X positions of the tool are all to the right of the origin, and positive Y positions of the tool are all "down" from the origin.

Rotate it so the index finger points along the X axis and the middle finger will point away from you...<br />Thank you<br />YuriyYuriyhttps://www.blogger.com/profile/11394499166280606198noreply@blogger.comtag:blogger.com,1999:blog-4429789698339059066.post-40566697269558429852014-01-19T07:30:48.892-08:002014-01-19T07:30:48.892-08:00Yuriy,

If you hold out your right hand the middle finger points in the left, or negative direction (as far a milling goes). If you use your left hand then the middle finger points to the right, or positive direction. Unless I'm missing something here.Helder22http://www.studioscale.comnoreply@blogger.com
