Another thing to keep in mind IS Mach3's scripting language is Cypress Basic . It is NOT Visual Basic(VB)

hIYA RICH. There were MANY discussions on it in past years.  BUT seeing how it will never ever be worked on again I don't see any point in cranking the discussion back up again. (;-)

Now another thing Sleep() is NOT just about waiting it also frees up teh CPU during a wait state and can allow OTHER processes to run while the wait is going on OTHERWISE teh wait can HOG all teh CPU resources and nothing else can happen.

(;-) WHile Ismoving is NOT just about MOVING it is about anytime MACH3 is doing something.  ALSO there is a problem with Mach 3 and CB spawning multiple threads at teh same time and loosing control over teh exact order of execution. SO it is left to teh programer to maintain order of execution in most cases.

You have a LOT to learn about Mach3 Grasshopper.

Another thing you MUST keep in mind is that mach3 is a GCODE motion controller. It is NOT a general purpose motion controller driven by scripting . Macros mixed with Gcode was an afterthought . MOST other controllers went with conditional Gcode instead of Macro interfaces to teh Gcode and in doing so can be much more stable AND FASTER in Gcode execution.

NOW once you learn how Mach3 works and learn most of the quircks MUCH can be done with it.  Just keep in mind that teh sampling rate of teh macros is ONLY 10 hz VERY SLOW as compared to other forms of motion control. SO by its own working Mixed Gcode macro can be very slow to function.

You will want to do the probing in INC (G91)mode. You hve to gather teh trip point values for both sides of teh circle. ( X1 ,X2 )You can then do a positional move in INC after you proper calculate the value you need to move OR simply switch  to ABS (G90) mode to do a positional move to Center of space. Then switch back to INC to do teh next G31 call and repeat as needed.



Code "G91"             ' Switch to INC mode
Code" G31 X-7 F8"   'Probe in X- direction
While IsMoving()
Wend
X1 = GetVar(2000)      ' Collect X1 trip position
While IsMoving()
Wend
Code " G0 X.050"         ' Back off switch in X + direction
While IsMoving()
Wend
Code " G31 X14 F8"      ' Probe X + Direction
While IsMoving()
Wend
X2 = GetVar(2000)       '  Collect X2 trip position
While Ismoving()
Wend
Xc =( X2 - X1)             ' This assumes you are in Quandrant 1
While IsMoving()
Wend
Code" G90"                 ' Switch to ABS mode
Code" G0 X" & Xc         ' Move to X center position

Double check t make SURE there are no left over DLL,s from a previous attemp to install .  THAT will cause problems.

Actually X1 would not have a value or would have teh previous value  from a previous G31.

#2000 would NOT be set untill after teh g31 is run. So in your example there is NO telling where it would end up.

AND because you did not switch back to G90 after the G31 ran the next move would be an inc move not abs. AND teh #2000 value IS an Abs position.

Clear as mud HUH ? (;-)

With teh hammer approach using inertial weight you will not have NEAR the cutter power as a levered (bolt cutter style) cutter. There are bascially only 2 methods to improve the cutting power of a hammer. 

Increase the speed of the hammer  ( larger air intake at the cylinder(more, faster flow) and a LARGE OPEN exhaust port area)

Increase the weight of the hammer ( not always the better choice )

Just make sure you keep your pinky away from that area.

Colin are you still trying to load drivers from the Mach3 site or did you go to teh UCCNC website and download them from there . I believe you are ONLY going to get teh new updated drivers from teh UCCNC website.
