Questions about FluidNC

Software / Firmware Jackpot Board / FluidNC

My FluidNC has been a little quirky so today I upgraded to v3.9.1. The install went well, but I have one new problem and some old. The new issue is with the Z probe. This worked with my old version of the firmware v3.7.16. Now the router will move down and touch the touch plate but does not retract. The signal light comes on and it does stop moving down but does not retract. I have the config set to retract 5mm. Am I missing something in the preferences or config?

My second issue is with the display of the machine and work coordinates. Pressing the 0xyz button (or the 0x, 0y, or 0z) most times (in both the old version and the new 3.9.1) does not change the displayed values of the work coordinates. Any suggestions to fix this?

Roll back to 3.7.17 for now. It’s the last known good version. Not perfect- but best available at the moment for production use (in my opinion.)

3.9.2-pre1 may turn out good, but there has been a lot of development swirl lately.

If you are using the probe button that is expected. If you use the milling basics probe start gcode it works as you want. I do not use the probe button so I never knew to test it. In the future I think we can get the button sorted but using the starting gcode is prefered.

Work coordinates are based off the end stops, the others are based off the current coordinate system you are in, again, this is as expected.

Just to clarify, pressing the 0xyz or 0x or 0y or 0z buttons does nothing to the coordinates displayed.

Does g92 x0 y0 z0 work?

I don’t use the buttons I use gcode from milling basics.

We can get the buttons sorted out if they don’t work, I just don’t think many people really use them.

Oh, and there is a lag, the update is not instant. I think by default it is 3 seconds between every refresh.

If the buttons are there the buttons should work. Everything else is just confusing. I had the same problem with the probe button (or rather a different one, but it didn’t work).

Absolutely right, thats why mine works with an really old stable version. Zero’s button should work. In mine i use them all the time

I agree fully, I just don’t think many people actually use them so they don’t get tested. This is the first I have heard about the Zero buttons so I will go check. We know about and have reported the probe not retracting.

Buttons make for a lot more work compared to gcode, so it is good practice to build it into your job.
