error when probing on the XY - start point too close to probe point

@rodw You have a rather unique situation. 95% of users will find probe basic very easy to install via the apt instructions, and updating becomes automatic with sudo apt update. Development is tricky due to venv requirement, but for those who want to customize there is a path to follow to get there.

@tommylight qtpyvcp uses vtk, which is super powerful and expandable, I envision some really cool things to come from it in the future including built in camming interactivity with graphical representation. Qtpyvcp is very flexible and not constrained to a single developers rule of law which makes its free flow of ideas and creation more accessibleand open. It's actually one of the primary reasons it was developed.

Probe basic makes almost all functionality available to end users in the form of subroutines making extensive python coding knowledge unneeded to adapt and make changes to suit users requirements. All of these are accessible in the config folder and do not require a development environment for most users.

The rs274ngc language is very easy to learn and adapt and has a wonderful single file user manual. Here:

Admittedly the user documentation for probe basic is lacking and that is squarely my fault but time constraints take their toll on all of us. I will get to it at some point or perhaps a generous user may take up the mantle to write it. My hope was to make it more of an interactive manual but that requires some code work I Hagerman been able to get sorted. Maybe soon hopefully.

ok ive been pulling my hair out trying to figure this out.  I am running linuxcnc 2.9 with probe basic.  I can probe z with no problems but whenever I probe an edge on X or Y i get the error - start point too close to probe point.  im not really sure where to go from here.  I have started the probing farther from the edges, closer to the edges, higher, farther from home point.  I can't seem to find this error hardly anywhere online.

I think I MIGHT know what you are referring to in the probing routine, try to use the CALIBRATION tab that applies to what you are trying to probe. If Z Maximum is much greater than the distance to the workpiece it will error out. Because it does not subtract the initial Z start height from the current Z position. But if you run the CALIBRATION tab and select  the square boss for an outside rectangle it will probe it correctly, just use the hint to put in the approximate part dimensions, and set your STEP OFF WIDTH accordingly.
