Hi Guys.
Would anyone be available to come help us set up a CNC machine Down South of Adelaide.. We purchases a 3 x 2 mtr 4 axis machine from China. Its all together and while I can get some movement, it dosnt seem right.
It is Mach 3 boards and software.. I just at am a loss.. Would be happy to pay a consulting fee or a Friday night BBQ.. LOL

Any help would be great

Hi Scott,

PM me for your machine specs and photos and detailed problems, we have provided consulting service to a lot of cnc customers.

Did you end up getting things up and running?

Hi Eddie, I discovered that my spindle wont rev below 1000 RPM.. This is all the problem was... The speed was set at 300..

The final thing I need to know is how to set up the Tool height. The router came with a device to be placed on the material and when the spindle is lowered down to touch it, it sets the height.. I am lost as to how to set this up though.. I know it works. as the it lights up one of the diagnostic lights.. Pin 4 I believe..

Thanks for asking Eddie.. any help on this would be great.. I still Havant actually used the CNC machine.. But I cant wait..

There is a script for it on GuruBrew https://youtu.be/G4DeVa8rzA0 change the script to what your touch plate thickness is and away you go kind of works well for me.

Thanks Inmesh
I Played with this script and another one for hours..

It sort of works.. But..

when it hits the ground plate.. 10mm thick..
1. it stops
2. moves up 300mm
3. Moves down 11 mm

I cant work it out..

This is my script it is for an 8mm plate and moves up 14mm.

CurrentFeed = GetOemDRO(818) 'Get the current feedrate to return to later
CurrentAbsInc = GetOemLED(48) 'Get the current G90/G91 state
CurrentGmode = GetOemDRO(819) 'Get the current G0/G1 state

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 P3" ' this delay gives me time to get from computer to hold probe in place
Code "G90 G31Z-50. F100" '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 exact point the probe was hit
Code "G0 25.0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend
Call SetDro (2, 8.00) ' change .060 to your plate thickness and then adjust for final accuracy
Sleep 200 'Pause for Dro to update.
Code "G1 Z15. F150" 'put the Z retract height you want here, must be greater than the touch plate thickness
While IsMoving ()
Wend
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 applicable
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
