Mach3 And SmoothStepper Getting Out Of Sync On Jogging....
« on: January 15, 2009, 03:52:35 PM »
I'm using the lockdown version of Mach3, and the v015me SS plug-in.  When I do a (manual) tool change, I often have to jog to position the tool over the work so I can set the Z position.  Occasionally, after doing this, Mach and the SS seem to be out of sync, as the DROs will show the correct position, but if I start the program, the machine moves to the wrong position.  For example, suppose it is at X=0 when the tool change occurs, and I jog to X=2, set the Z height, then hit Run.  If the next move is to X=4, it will instead move to X=6, though the DRO will indicate X=4.  Oddly, if I then do a G0 X0, it does correctly go to Z=0 and it's fine after that.  I have experienced this problem intermittently for months.

Is this fixed in the current SS plugin?

Never had that prob Ray, mine was a bit different in that it was only after a homing move and because I have external homing (in drives) Mach thinks I dont have any home switches and so was not updating occasionally when I had homed. But what would happen is I would say G0X100 and it would move to some weird position but the DRO would correspond to that weird position so it is very different from yours. To cure mine all I had to do was press the Ref All twice (actually did it in VB rather than physically pressing)

Hood,
Well, I'm not the only one seeing this.  One of the guys on the Yahoo group is working with Greg and Brian to sort it out.  It's really wierd.  Today I had it sitting at x0, y0.  I  jogged to x3, then MDI's "g0 x0 y0", which did NOTHING.  The x DRO still said 3.0000.  I did it a second time, and still nothing.  I jogged, to make sure the axis was still alive, then MDI'd "g0 x0" and it went to x0.

Hood,

Apparently Greg has just identified the root cause of my problem, and will have a fix shortly.

Thats great news, knew Spence was having issues but was unclear exactly what they were. Seems like there were several different small bugs and it was certainly weird that it happened on some systems and not others, I think even Spence could only get this problem on one of three or four computers he uses.
