General Mach Discussion / Re: Mach3 Auto Z Won't Retract

Your missing lines earlier in your code that should say:
PlateThickness = 0.787402
Retract = 0.1

Or, you could just use:

Code "G0 Z0.878402"

Thanks, I actually had these lines in the code and played with them for an hour before coming in here for help.  I had it all set up a couple weeks ago but bought a Vista MPG and set that up.  I upgraded to Windows 10 before realizing Mach3 would not run with Windows 10.  I tried to uninstall and reinstall Mach3 on 10, then realized I lost all my Mach3 codes I did.  Really wish I remembered to copy the Auto Z code. I swear I am going though the same thing but it does no retract for some reason.  I get it to put the plate thickness in the DRO and to say "Z is Zeroed" in the window, but the bit sits touching the plate.  In the diagnostic screen the "green" light stays lit as well unless I manually back the bit off.

I will try again in a bit, not sure what I am missing.

Thanks, it still does not retract at all though... yours pulls back?

General Mach Discussion / Mach3 Auto Z Won't Retract
« on: April 24, 2016, 12:02:34 AM »
Having problems getting the Auto Z and touch plate/probe to retract.

Any ideas?  I am not a programmer and am lost...

What needs to go here:

Code "G0 Z" &Retract+PlateThickness 'put the Z retract height you want here

My retract is 0.10"
My PlateThickness is 0.787402"

Thank you

ahh, that is right 1/10,000 duh, read it wrong. 

"It should be probing at 4 ipm, based on the F4 in this line:

Code "G31Z-1 F4""

Great, thanks!

Yeah!  I got it working...

I am using this script below but 2 questions:

I have my plate thickness at .7874 and the retract to .10 which should = 8874 but it = 8875 on the DRO?  Is there a thousandth offset in the code or something?

Also, in the code, is there something that keeps the Z axis jog rate hard coded as I set the Z zero or do I have to manually hit the TAB key and reduce the jog rate each time and then manually reset the jog rate back?  I am nervouse thet if I do not manually hit TAB and reduce the jog rate from 100% to .3% that it is just going to go flying down to the touch plate...  I would like to have the TAB jog rate be at 100% all the time but when I hit Auto Z Zero in mach 3 it over ride that in the code and go down slow such as .3% for the auto zero.





CurrentFeed = GetOemDRO(818) 'Get the current feedrate to return to later
PlateThickness = GetOemDRO(1151)
Retract = 0.10

If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty
DoOEMButton (1010) 'zero the Z axis so the probe move will start from here
Code "G4 P2" ' this delay gives me time to get from computer to hold probe in place
Code "G31Z-1 F4" 'probing move, can set the feed rate here as well as how far to move
While IsMoving() 'wait while it happens
Wend
ZProbePos = GetVar(2002) 'get the axact point the probe was hit
Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend
Call SetDro (2, PlateThickness) 'set the Z axis DRO to whatever is set as plate thickness
Code "G4 P0.25" 'Pause for Dro to update.
Code "G0 Z" &Retract+PlateThickness 'put the Z retract height you want here
Code "(Z axis is now zeroed)" 'puts this message in the status bar
Code "F" &CurrentFeed 'Returns to prior feed rate
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if aplicable
Exit Sub
End If

" edit the button script"

Yes, can someone show me the best place for the script or instructions?  I need to offset it 20mm (but I use Imperial)

so should I use the actual ground pin on the BOB in that schematic?  Or ground it to a part of the machine?

So do I use the ground for the gator clip and the plate wire in pin 13 (or pin 15)?

General Mach Discussion / Wiring Z Zero Plate to BOB

Hi finally got my auto Z Plate but am lost on what to do...

I have a Romaxx WD-1 machine which has a couple pins left on the input 1 (these are for a MPG which I use a usb instead)

I was told I could use these ports for the touch plate.  It has a black and white wire, one for the plate one for the gator clip.  This is the standard Chinese ones sold everywhere.

I have:

Port 1 pin 13 A Channel
Port 1 pin 15 B Channel

Does a wire go into each of them?
Is there no need for a ground?

Thanks!

General Mach Discussion / Z Zero Offset for Touch Plate
« on: March 15, 2016, 10:59:02 PM »
I am looking to adding a touch plate for Z Zero.  Perhaps just one that lights up when the bit touches the metal and then having say .125" away from actual Z zero height.  How do I offset that .125" so that Mach3 accounts for it and goes to actual surfae Zero?

Thanks for any help,

I have looked around but I am getting a bit lost.  If there is an easy answer, thread or video it would be appreciated.

Also, if any one could recommended a simple to use/make/purchase touchplate  one it would be great.  I am looking to keep away from wiring the BOB.
