General Mach Discussion / How to get rid of offset
« on: November 06, 2014, 01:08:46 PM »
I have this line every single time in the G code.
N140G00G43Z20.320H1

If I leave it, it screws up the Z auto zero after I zero it.

I delete it every time and it's fine. How do I get it to stop inserting it??

Easy , just swap out the driver and see what happens. If it persists then swap out the motor and driver together. If it persists it's the BOB. If it gets solved before that it's the last item you changed.

All my bits are tool 1 it would seem. I looked in the tool database but is there somewhere else?

I think I found something.

N130 (V-Bit {60 deg 0.5"})
N140G00G43Z0.8000H1

that is some G code from the beginning of the file.  Is that what you meant about G43?? If so how do I stop it from doing that??

Well I use an auto zero script from this forum and sometimes when I set it manually it does the same thing. I'll look for a G43 code. I have Aspire that makes my G code.
Thank you Gerry.

General Mach Discussion / Z height unstable
« on: September 09, 2014, 02:47:33 PM »
Good day folks. When I set the Z either using AUTO ZERO button or manually, it doesn't seem to "remember" it. So many times I Have set the Z to zero then ran the code and it plunges into the work or sits and moves around in the air.
What gives?? Am I missing a setting or something??

MACH 3  Version R3.043.066  is what I am using.

I would love to fix this.

General Mach Discussion / Please help auto tool zero not working--
« on: September 27, 2013, 01:42:48 PM »
What am I doing wrong? I use the auto tool zero macro and it sets the tool height to zero.

BUT then when I go to cut it either is off too high or too low and it isn't at zero where it should be.
I just ruined a box I was making, please help me figure this out??

Do you have to regen the toolpath or that have nothing to do with it? Sometimes i do and it still doesn't work.

Here is my script....

CurrentAbsInc = GetOemLED (48) 'Copy current G90/G91 state
CurrentGMode = GetOemDRO (819) 'Copy current G0/G1 state
CurrentFeed = GetOemDRO (818) 'Copy current feedrate
Contact = 0 'Clear the contact flag
PlateThickness = 1.560 'Touch Plate thickness is set here
ProbeFeed = 80'Probing feedrate is set here
SetVar (1, -20) 'Maximum probing distance is set here
SetVar (2, 5) 'Retract height is set here
Code "M5" 'Ensures spindle is not running
Code G21 'Ensure metric units are used
Zs = GetOemDRO (61) 'Copy current Z-Scale DRO
Call SetOemDRO (61,1) 'Set Z-Scale DRO to 1
Label1: 'Entry point for Retry
DoOemButton (1010) 'Zero Z-Axis DRO
Code "(Setting Tool Zero)" 'Message for status bar
While IsMoving () 'Wait until task has been completed
Wend
If GetOemLED (825) = 0 Then 'Check to see if touch plate is already grounded
Code "G90 G31 Z #1 F" & ProbeFeed 'Probing move
While IsMoving () 'Wait until task has been completed
Wend
If GetOemLED (825) = True Then 'Check to see if probe has touched plate
Contact = 1 'Set the contact flag
End If
DoOemButton (1003) 'Clear a possible feed-hold condition
ProbePos = GetVar (2002) 'Exact point probe touched
Code "G0 Z" & ProbePos 'Go back to exact point of touch if there was any overrun
While IsMoving () 'Wait until task has been completed
Wend
Call SetDRO (2,PlateThickness) 'Set Z-Axis DRO to Touch Plate thickness
Code "G0 Z #2" 'Retract off Touch Plate the set distance
While IsMoving () 'Wait until task has been completed
Wend
Code "(Z-Axis is now Zeroed.)" 'Message for status bar
Code "F" & CurrentFeed 'Restore feedrate to original setting
If Contact = 0 Then 'Probe reached max travel without touching
Code "(ERROR - Probe did not touch.)" 'Message for status bar
Response = MsgBox ("ERROR - Probe did not touch.",37,"Auto Tool Zero")
If (Response = 4) Then 'User chose Retry
GoTo Label1 'Retry Probing routine
End If
End If
Else
Code "(ERROR - Touch Plate is grounded.)" 'Message for status bar
Response = MsgBox ("ERROR - Touch Plate is grounded - Check connection.",16,"Auto Tool Zero")
End If
Call SetOemDRO (61,Zs) 'Restore Z-Scale DRO to original setting
If CurrentAbsInc = 0 Then 'If G91 was in effect before then return to it
Code "G91"
End If
If CurrentGMode = 0 Then 'If G0 was in effect before then return to it
Code "G0"
End If

Thanks....

Which code would you like? Sorry I am not sure.

Yes I set the machine up to have 0,0,0 on the front left of the table so if you were standing in front of it looking at it then Y is left to right X is towards(-) and away(+) from you and of Z up and down.

The files I run cut fine and come out right. The JOG X+ button makes the X axis DRO go UP in numbers, BUT it goes towards me so it's actually going NEG direction. Odd.

Ok so I checked what you are saying I zero'ed the axis and clicked on X+ and it went + in the DRO, BUT it goes towards the front of the table which should be - direction. It cuts the text I have OK so I don't know why it does what it does.

Stirling the text I mean is what I am trying to cut, some simple test text into wood. I have no idea what wizard you mean.

When I click on the X+ it goes the wrong way and counts down instead of up. Funny thing is, it cuts correctly.
