Thanks,  I just noticed the post.  I will have a look.  I was turning a blind eye to speed because is not an issue today, but when the depression is over we would regret having overlooked it.

Hood,

Thanks for the VB it works well.  I added to it absolute and incremental.  I think it will make a nice page for doing simple cuts on the router.

Gary,

Please send links to the Direct components you reference.  There are numerous hits on DL06.  I like the concept . .  we built a PLC controlled edging cross-cut saw.  I outlined the ladder, but we used outside resources to actually program it.  We also have other PLC stuff and have just as much trouble with them as anything else.  I actually have a PC that has been running since 1998 without failure. It runs DOS and a CNC Router. If the grid is up, it's up.  However, I am on my third high buck touch screen panel mount PC for the current router project.

The fence we are working on weighs about 500 pounds and has about 12 inches of travel. Although it would be nice to count pieces, it is not a feasible task.  What did you have in mind for the HMI?  The fence has a variable zero and a fixed Zero.  The operator would need to set the variable zero and then enter the desired offset values from that zero . . . usually not more than 4 total.  The fixed zero has 5 negative values.

Thanks, I get the concept and will give it a go. We have the carriage and rails for the fence installed, but planed to crank it by hand or an analog gear motor.  The industrial drives are very expensive and still require substantial mods to adapt to the application.  Mach with two slaved lead-screws will do just fine.  I am amazed by the versatility of the software at its price.  The help from the forum is fantastic too.

Thanks again for the help.  Also, my personal router has not crashed again after following your sage advice.

Thanks.  Easy for someone who knows how to write VB.  Can there be multiple buttons and DROs?  Do you have a VB script in mind or can you direct me to instructions on VB as it applies to Mach?  I am just starting to mess with screen design.  I am using Klaus, MachScreen V 1.60, is that a correct approach?

I would like to move/index a fence with Mach.  To be efficient it would require that the move to value could be entered and retained in a data-field or MDI window.  A start button adjacent to the field would command the movement to the entered value.  There would be several button/fields.  Thus the operator would enter the various values at the begging of the operation and then simply press the appropriate button for the desired fence location.  That is, 1",  2 1/2 ", 4" and so on.  A button command script  to move the axis that calls up the variable entered in the data-field??? 

Please help.

It seems out farther than that.  Just messing with the spoil board and framing square it shows out of square in the same direct each time.  I have applied pressure in the direction of correction but that causes the otherwise smooth gantry to rumble.  I need to do some measuring, but it could be out as much as 1/8 inch overall.  I hoped there could be a software compensation.  A mechanical adjustment is not obvious.  I guess having no manual is the bitterness that results from buying cheap stuff.

Is there a software fix for an out of square gantry?

Pray tell, what jog settings?  If they are in the xml they are set by the BOB folks.  I did today check some of the stuff you mentioned.  Every BOB termination was loose.  Not sure what that would do, but in a water pipe it would drip from time to time.

Geh,

We just completed a dry run with no issue.  It's now running the cycle with the router on but not in the cut.  While running, I tripped the proximity switches one by one and there was no response from the BOB or Mach.
