Indeed I am Phil but I still love M&M's ...... especially the green ones  Cheesy

I love em all. 

Phill  what code are you asking about?  Can you open it in an editor?  Look for an F command and change it to what you want.

As i say its the one that's inbuilt but having tried the one posted by Dave AKA budman68 i think that one is better as you don't have to unload your gcode to run it.

I applied the code to the centre button on the offsets page.

I did try with no success to change the X & Y DRO's to zero at the end of the routine.

Thanks for that Dave.

It was the built in probe routine that i was after changing but i will try that one.

I agree about speed being important if i go too slow i get an error, and if i go too fast i **** myself    hence my desire to hard code it.

Then i will not have to go thought it again if i have the speed incorrect.

As your using IPM's you must be the other side of the pond although brought up on imperial i prefer M & M's

I actually find 200 MM PM is best "8 IPM"

General Mach Discussion / Mach Built In Find Hole Centre Probe Routine

Is it possible to edit the routine. If yes please mention how.

I am using version 2.63 and what i do not like is it uses the current feedrate.

I want to SET a feedrate of MY chosing.

All help appreciated.

General Mach Discussion / Re: Scripting Help Tool Zero

« on: August 17, 2008, 05:43:59 AM »

Hi Greolt,

I have just tested the script it does exactly what i want. 

It seems explaining what you want is harder than the actual coding. 

Thanks also to Brett "Chaoticone" for your kind offer via PM and help thus far but Greolt just beat you to it.

This came about as i am engineering rather than routing and i cannot always get my touch plate in a position to get a Touch

So i touch off on another face and either add or subtract to get me back to where my datum is.

I did not want the zero tool thickness coming into the equation "Outside Of The Script" as a mistake can have disastrous consequences IE i wanted that thickness left hard coded where it would always be correct.

I think i may change the title to reflect what i consider a usefull addition to the Auto Tool Zero Script.

Brett i appreciate your help.

I just didn't think this would be so difficult.

General Mach Discussion / Re: M3 / M5 execution delay

« on: August 14, 2008, 12:18:16 PM »

How about using a spare axis

Your machine seems to be two axis "Say X & Y"

So using metric as an example Z is always 0 = M5 Turn Off when Z becomes 0.01 = M3 Turn On

Example cut out square 100x100

G0 Z0 its off
G0 X100 Y100
G0 Z.01 Turns On
G1 X200
G1 Y200
G1 X100
G1 Y100
G0 Z0 Turns Off

You would need some sort of custom electronics to interface with the pulses but people do make there own drivers so it should be possible ?

Hi Brett i appreciate your patience.

I am using that Zero tool as is, i have made a touch plate that is nearly 13mm thick as i also use the probe by a guy over in the USA i am sorry i have forgotten who. "So my plate touches when it breaks contact".

All the coding is inside the script, i just touch down then i am at Zero.

But i want a dro on the screen so that if it says 0.0000 then when i use my touch tool then i am at zero on the top of my workpiece.

But i want this dro to add an offset so that if i enter 12 then when i zero i am actually 12 mm "PART THICKNESS NOT PLATE THICKNESS"

As i say in my original post i want to add to the script so that i can set an offset either in the plus or minus direction.

This is how i do it at the moment

What i am doing  is touching top of workpiece "Z reads Zero"

I move away use MDI G0 Z0 my tool is at zero according to the touch plate then change the Z dro  to what i actually want, 12mm in this case but it could be 3mm 15mm 1.mm or Zero if dro is empty

So this is maybe how it works i have a dro on my desktop it has 12 in it i run the standard script and at the end after going to the retract height it then says does "Z=Z+dro" or something to that effect to reach my goal of adding a figure in my dro the the z figure.

Does that make sense.
