Candle Z Probe option missing??

[PaulHosh]

Hello

My apologies in advance for what is a simple misunderstanding on my part.

I am unable to select the Z-probe option on Candle. I have turned on all screens via the View menu command and I just don't see where this option is located.

My CNC has the GRBL 1.1h installed and I am using Candle version: 1.2.13b . Homing works fine.

Since I cannot find this option, I used the following command

G91G21G38.2Z-20 F100

There is no motion on the Z axis. It has been suggested to disable the soft limits. Why this should an answer is not clear to me. There must be some condition that I have to clear/set to get this command to work. Candle does not report any errors for this command string.

the settings are $0=10 $1=25 $2=0 $3=6 $4=0 $5=1 $6=0 $10=1 $11=0.010 $12=0.002 $13=0 $20=1 $21=1 $22=1 $23=0 $24=400.000 $25=400.000 $26=250 $27=20.000 $30=1000 $31=0 $32=0 $100=5.000 $101=25.000 $102=40.000 $110=500.000 $111=500.000 $112=500.000 $120=10.000 $121=10.000 $122=10.000 $130=440.000 $131=550.000 $132=215.000

Any suggestions to assist me would be appreciated. Kind regards Paul

Hello. Please share the screenshot of the top-left "Visualizer" corner view:

What is the response for your command?

Try manually connect the probe. Do you see the difference it the top-left "Visualizer" corner view?

Maybe you need to configure your probe as inverted ($6 setting), just like your limit pins. Please answer the questions first.

I have a similar problem as Paul, but I do have an icon for running the probe option. It is basically what Paul typed above but the Z search distance, retract, and probe height are different. Versions Candle 1.1.15b / grbl 1.1f / Win10 User command Icon: G21G91 G38.2Z-30F100 G0Z1 G38.2Z-2F10

I get no motor response from either the user command icon or the command string and the numbers in the "Visualizer" do not change. G21G91 < ok G38.2Z-30F100 [MSG:Reset to continue] After reset: [CTRL+X] < ALARM:2 Grbl 1.1f ['$' for help] [MSG:'$H'|'$X' to unlock] S1000 < error:9 then unlock: $X < [MSG:Caution: Unlocked] ok S1000 < ok

If I manually short the probe out, The PS: has a P as long as the probes are shorted. The alarm 2 is missing value in command, but the command looks complete.

Thanks

@pixelwaster Please share your GRBL settings ($$ command output) and screenshot of the window with working and machine coordinates. "Reset to continue" message reported when hard or soft limit reached.

@pixelwaster You have soft limits enabled ($20=1) and max. Z travel is 41 mm ($132=41). Try to disable the soft limits with $20=0 and check Z probe behavior. Or consider to use other Z probe limit (instead of "Z-30") to avoid soft limits event triggering.

Thanks for the help. I changed the Z probe limit to -10; I've just gotten used to eyeballing the Z. The -30 is the default value in Candle. If the probe started from HOME, then the -30 would be fine.
