Lift Z axis in pause state

MillMage Software Questions
1

midway through a job, a small cut out piece , while being sucked out by the extractor , the tool managed to drive itself into said piece amazingly it didn’t break the tool of 3mm, i paused job turned off router , went into move panel / jog and tried to lift z axis to remove stuck piece , nothing happened
tried position tab , entered a higher z position , than clicked go to z , no movement ?

is it possible to manually lift Z axis while job is paused

had an after thought could i create a custom g code in the pause box to lift z axis when ever i click pause
would the resume need to be altered also?

unsure of which code to use or format to type it
any help appreciated

Not shure but I don’t think you can move the head as it has just stopped at current gcode. Then strart just executes the gcode from pause.

This is true, Lightburn has halted the stream, but is still in the “feed” mode. “Stop” halts the feed mode and enables the Windows focus to be set to the Move window.

thought as much , but hey , got ask theses questions , never know someone may have changed the wheel and found a way

You maybe able to override with a macro? Unpause, comand z up stop pause, another to lower z to original height and unpause. But I don’t know if macro can do this.

You would still need MillMage to give focus to Console window, which by the way I discovered has no Macro buttons.

Did they hide the Macro buttons somewhere else?

me and macros , dont get on , they never do what i tell them :unamused_face: :rofl:

why cant it be as simple as delete the pause command
change it to something like

G0 Z0 F300
@P ISSUE RESOLVED RESUME JOB
G38.2 Z-110 F200 P0.5 (Probe set thickness)
G00 Z60 F500 (Clearance)
@P REMOVE PROBE

Where did you get the @P GRBL command? I cannot find a reference to it.

not sure if this has just been added to docs but i didn’t stumble upon it when i was having tool change issues
waas having issues with tool change commands freezing , created topic around same time a video came out with custom g codes
MM dosent like M0 if running direct to cnc
but understands @P
right side page click tool change

Ok, I see. It is a MillMage thing, not GRBL. Thanks!

hi colin
just wondering if you or one of the other techs could look at my post

and see if my crazy idea is possible for changing pause gcode

13

We’ve discussed this thread specifically internally. There’s some technical limitations depending on the device’s firmware, but it’s probably possible with grblHAL and FluidNC devices.

It’s on the board.

Just moved this into the topic thread to keep the information together.

i have the fluidnc board, are you saying may need to alter board firmware and it may work
i saved all my pref and bundles
than had a play with some codes
using the below
!
G0 Z0 F300
@P ISSUE RESOLVED RESUME JOB
G38.2 Z-110 F200 P0.5 (Probe set thickness)
G00 Z60 F500 (Clearance)
@P REMOVE PROBE

at one stage of the air test (file was one ive run a few times )
from when i clicked pause button to when it actually happened was maybe 5 sec it paused went to z0 sat there for about 5 sec but than went to xo yo
brought up change tool box on screen (as if it was mid job and doing tool change
these are my tool change codes

$HZ (Home Z)
G0 X10 Y10 F2520
@P CHANGE TOOL – {tool_name}
G38.2 Z-110 F200 P0.5 (Probe set thickness)
G00 Z60 F500 (Clearance)
@P REMOVE PROBE

so i did the re probe etc and than it sat at x0 yo for maybe 10 sec than it moved back to position of where i had clicked pause and continued job

and dumb me forgot to save screenshot of console ,think i have job log enabled

i tried few other ways removing the ! replacing it with @ , the job started as per normal , soon as i clicked the pause button on job control screen that was it, it paused , couldn’t resume or even stop job, was click close MM reload MM got to point it didn’t like some things i tried and wouldn’t even start a job, even after removing all codes from pause box nothing
reloaded all preferences and bundles back to normal
So guess it looks possible just got work out the right codes and sequences
knowing i can reload preferences and bundles and it will return to my old settings ill keep trying, but altering firmware on board that’s way over my head
