fabrun: it turned out to be a case of extremely bad timing. The board was fine, but a connection in the power plug was intermittent.

I am having a problem with the Auto Tool Zero button, if you wouldn't mind taking a look, the post is here: http://www.machsupport.com/forum/index.php?topic=25116

Keleide: sounds like a good upgrade!

Thanks :)

Weird. On my Input Signals tab (Config/Ports and Pins), all the enabled signals are Port 1, and pins from 1-5, 7, and 9-32 assigned to the various signals...

At any rate, back to the original issue, anyone have an idea why the script isn't resetting the Zero Z DRO?

Thanks for the replys.
Gerry, it's wired to port 1, pin 7, and in the Diagnostics screen, the Digitize light is lit when the circuit is completed.
I assume it's a valid version, I bought the whole shebang (cnc router, laptop, mach3) second-hand.

I did inadvertently hit the "Remember" button under the Auto Tool Zero button if that makes a difference.

I'm sure it's something that I'm missing.

Thanks again.

Any additional help? Thanks in advance.

Hi Gerry, thanks for the reply.
I'm using the default screenset, so no idea if it has DRO # 1151 or not. I thought it was one of those two "gage" block DROs, since that's what the image next to them is showing. Not a big deal, since the height of the gauge block won't change.

The probe itself works fine. I stepped through the code, added a breakpoint and checked the value that way (same end result as adding a msgbox), and it always returns "0"

Hey all,
I've been trying to set up a touch plate, and having little to no success. I'm using the script that seems to have been going around for a few years:

Code: [Select]
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
PlateThickness = .028 'Z-plate thickness DRO

 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 "G90 G31Z-5 F5" 'probing move, can set the feed rate here as well as how far to move
 While IsMoving() 'wait while it happens
 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 ()
 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 "G1 Z0.5 F10" 'put the Z retract height you want here
 While IsMoving ()
 Code "(Z axis is now zeroed)" 'puts this message in the status bar
 Code "F" &CurrentFeed 'Returns to prior feed rate
 Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if aplicable
 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
 Exit Sub 

The main issue is that GetVar(2002) always returns "0" regardless of where the probe touched.
Also, I hard-coded the plate thickness, since GetUserDRO(1151) also always returned "0" (I entered the thickness in both of the "Gage (sic) Block Height" DROs in the Offsets tab -- why are there two anyway?)

Any help is greatly appreciated.

Yup, that's exactly what I did. It worked once, then nothing...

Well, I tried to add a touch off plate (for auto-zeroing the Z axis) following the instructions, and I think I fried my board. Translating Chinglish is a skill that I apparently lack.
Like alexcfw, I found a replacement on Aliexpress for about $215 USD, but haven't ever bought anything on there before. Here goes nothing :)

Ah, I configured the spindle settings to what was shown in a screenshot in the JNC manual, which was different than what was pre-configured. I reset the settings, and now the spindle works. I probably should have thought of that first :)

Have you been able to automatically start the cooling pump?

Thanks again, Mike. One more question: I haven't yet been able to get my spindle spinning. All my settings relating to the spindle are correct according to the JNC manual, would you be able to provide your settings?

renatom: I haven't had that issue, but I completely cleaned the machine, including wiping the ball screws and rails down with acetone, blowing everything out with compressed air, then lubricating all the moving bits. When they were built, they weren't cleaned at all. The fabricators just left all the shavings and crap from drilling and tapping and whatnot in the machine.
