Hi,
this afternoon I downloaded the current latest development build of Mach4. It has the new surface mapping
feature and I've been experimenting with it. I haven't had anything like the time to work out all the quirks yet
but this could, in fact almost certainly, be a worthy alternative to the Autoleveller solution.
I have attached a picture of the Surface Mapping generating screen. Note that it is in Machine coordinates and may
require a certain amount of thought before banging in some parameters.
The up shot is you program the X and Y extents of the area to be mapped, the target resolution between the sample points,
the probing speed, the Z axis retract height and the vertical Z probe movement the hit <Map Surface> and Mach obediently
probes the entire area and saves that as a map file. The mapping generator is a Wizard....too easy!!
I have yet to work out how Mach handles the results of the file, but it looks like you select the surface map file
in the Surface Map plugin and thereafter the Z axis machine coordinate Z datum goes up and down automatically.
So unlike Autoleveller you do not have to modify the Gcode to accommodate an uneven surface the datum goes up
and down instead.......how bloody clever is that!!
You might like Mach3 but you are being left behind
BIGTIME!, get with Mach4, go mad early and beat the rush!
