Hi Im back again with more z probe problems. Well really its the same problem I just havent been able to use my machine in a while and its been so long I didnt want to revive a dead thread.
Problem- When I use the z probe the spindle wont go down to the correct height.
Yes I have been through the setup. Yes I have been through the advanced setup and changed the probe height.
I think the problem is that its not saving my setup because no matter what values I enter there it will just stay at the same height. Any Ideas why it wouldnt be saving? Also its very annoying you have to go through the whole setup just to get to the z probe one.
It doesnt matter where I start it. The router always goes to the same height. Im going out now to try and see if changing my browser or clearing my cache helps.
Always go to the same height when? After probing? Starting the carve?
The Z probe routine moves the Z axis off the same distance off the plate after it’s done with a relative move but that’s not the zero position that is set. If it tried to go to Z zero, it’d crash into the probe.
If you want to check the zero position, you’ll need to issue a go to zero command in machine inspector after removing your Z probe block. Try “G90 G0 Z0”. That’ll move to the Z zero position which should be the point where the bit touches the material.
It always goes to the same position after I start to carve. I have changed the thickness of the probe to be thicker in the settings which means it should go down farther when i start to carve but it still stays at the same height as its default.
That being said when I did enter the advanced settings the thickness of the probe was correct so Im not really sure why it wouldnt work in the first place. It finds the probe just fine and retracts to the correct height once its found the probe.
I just tried two different browsers and cleared my cache which made no difference.
I entered that code in after probing and it went to the same place it always does which seems to be about .15 inches off the material.
0.15" is the default safety height in Easel but that doesn’t explain why his zero point is his safety height.
Is this the Xcontroller or the Arduino/Gshield?
I’m wondering if you have some persistent offset stored on the controller and it’s causing this. Have you power cycled your controller at all while trying this?
After you probe, go into Machine Inspector and enter in “$#” and post the response.
After probing I entered $# and this is what I got.

So the good news is your probing is working just fine.
Notice that your PRB status indicates 26.178 for Z. If you subtract 0.59 in (14.986) from that you get 11.192 which is pretty close to what is set in G54 (probably some rounding going on with metric to imperial).
Now, were you clicking the jog Z button before or after the probe sequence? Trying to understand the Z movement commands. Easel console is usually most recent down first but some of it isn’t making sense.
If you want to check if your probe settings get changed, if you do the same thing (enter $# after probe), the line with the G38.2 in it should change the 0.59 to the new thickness and if you change the max travel the “3.1” will change.
this is what I got after changing the probe to 0.6 and the max travel to 3.5. That doesnt make any sense though because after attempting to cut again the router is still at 0.15
That’s not the G-code. That is the parameter list. What I would like to see is the first lines of the G-code file. If you are using Easel you may have to export the G-code to a file in order to see what was generated.
To post the first few lines of Gcode as Larry is asking, in Easel go to Machine -> Advanced then click “Generate Gcode” and then click “Export Gcode” when it pops up. A .nc file will be downloaded and can be open in Notepad. Copy the first 20 lines here.
