Hi , Terry

Thanks for the thaught's, Brain's will be the answer one way or the other.

Thinking about an independent Z up down system with an encoder or switches to follow hight, Like plasma auto hight control's have.

Really need something on the fly.

Thanks, Chip

Hi, Wayne C

"Should I be entering the NEGATIVE value of the plate thickness- i.e - .125? "

Yes your Gcode should be  Z- .125

Thanks, Chip

Hi, Gbecerra

MachLic.data-file, $160.00 Removes the 500 or 1000 line limit from Mach depending on version and turns on some other items, I don't have a list.

LazyLic.data-file, $75.00 allows offsetting, pocketing and turn features.

Thanks, Chip

Hi, Tmsmith

Center mouse wheel, press and move mouse will do it, Don't think there's any other way.

Thanks, Chip

I asked this question sometime back, Example, A windshield laid flat on a water jet cutter table..

Is there a way Mach3 can follow a X,Y path, set to pick-up Z value (set to probe at X Y move distance  say .250) and incorporate it into a new file with X Y Z moves.

Need to trim off some excess edges, on some (one off) curved shapes 2 x 4 feet, plasma, Water-jet ?.

Any Thoughts Ideas ??

Thanks, Chip

Hi, Rkjohn

Is this flat spot in line with one axis, Clock angle 9:00 3:00 X, 12:00 6:00 Y, or a combination of X,Y 1:30 4:30 7:30 10:30.

You could get started by enabling the backlash and putting in an estimated value's for X, Y or both X Y.

Thanks, Chip

Hi, Rkjohn

First theres a Jog/MPG Screen if you haven't found it, Under the Tab key, It may make it easer ? Learning curve.

Jog Mode, "Step", Cycle Jog Step, "click on it or to the right click to enter value.

Check for backlash in Axis's.

Best done with a dial indicator with 1 inch of travel,

Setup as Picture below, Jog left .750 then re-zero dial indicator 0 mark, Zero X on Mach3 Prog. Run Screen.

(this takes the backlash out to the left if any when your moving right).

Now jog .500 to the right, Dial indicator should read .500 and Mach will indicate .500, Record the distance moved.

(If the indicator shows above/below .500, Your steps Per. Unit  are incorrect in motor tuning for the axis).

I would repeat Above until you get units set as correct/close as you can.

Now Jog left .500, Mach will show 0 and indicator should read 0 again "if no backlash".

If the pointer didn't make it back to 0, The distance to go to 0 is your Backlash value.

Backlash can be turned on and set under Config, Backlash, Enter the value for axis, Check the Enable Box then OK, Re-start of Mach Required.

Where to start where to stop.

Hope this Helps, Chip

Hi, Dennis

Did you download the diag.'s I sent you a total of 3.

Hi, Kurtht

Hears a typical diag. of a UNC5804B IC, Pin 15 is used to Enable/Disable the output, Gnd Enables it.

Hope this Helps, Chjip
