Yes, please keep us up to date on your progress Pop. Very interested in this.

Hi Sam,

Sorry that the version I am using still causes the same problem. Looks like you have a bit more experimentation to do before you find the solution.

btw. At your suggestion I went and had a beer (or two) anyway.

Not good news Pop.

Although Mach supports Rotational interpolation it was primarily designed for linear movement control so I think you will be struggling with this project.
Once you have stepper control of the arm the Mach 'Teach wizard' could be used to compile the GCode to follow the moves that you have made manually but none of the (realistically priced) software I have encountered so far will compile code for an arm.
Good luck with your project.

Hope that's just spray paint Chris and not real gold.

The final (Z axis) mock-up mirror mounting and tool made for inserting the springs.

Nice machine you have built there Dimitar. Do you have a final build cost ?.
Think it would probably take me 60 days just to do the wiring.

Hi Sam,
This is the code I am using without any issues. It is very similar but with slight differences.

CurrentAbsInc = GetOemLED(48) 'Get the current G90/G91 state
CurrentGmode = GetOemDRO(819) 'Get the current G0/G1 state
CurrentFeed = GetOemDRO(818) 'Get the current feedrate
DoOEMButton (1010) 'zero Z DRO
PlateThickness = 2.8 'Touch plate thickness is set here
ProbeFeed = 10 'Z axis feedrate is set here
If GetOemLed (825)=0 Then 'Check to see if plate is already grounded
Code "G31Z -15 F" &ProbeFeed 'Probing move at ProbeFeed rate
While IsMoving() 'Wait for Z move
Wend
Code "G4 P0 .25" 'Pause for DRO to update
ZProbePos = GetVar(2002) 'Exact point probe touches
Code "G0 Z" &ZProbePos 'Go back to exact point of touch if there was any overrun
While IsMoving () 'Wait for Z move
Wend
Call SetDro (2, PlateThickness) 'Set DRO to plate thickness
Code "G4 P0 .25" 'Pause for DRO to update.
Code "G0 Z5" 'Z retract height is set here
Code "(Z axis is now zeroed)" 'Message for status bar
Code "F" &CurrentFeed 'Reset original feedrate
Else
Code "(Z-Plate is grounded, check connection and try again)" 'Message for status bar
End If
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 for the reminder Dave.
I, for one, sometimes exist in my own little world and are not always mindful of others.
