Is there anyone that has considered or has created tool(s) that tram their machine with software? This would require probing a number of locations around the boundary of the job and a central locations. I have this function in my other CNC mills controller and would like to see if it would be possible to get this function working in GSender.
You say ‘traming’ but it sure sounds like you are talking about surface mapping. I can not see how traming can be done in software (but I would listen to an explanation if there is one)

@Jens I was thinking the same thing.
@mjeanson Tramming is when you adjust your spindle so that it’s perfectly perpendicular to the bed.
As for surface mapping or height mapping, it’s been a requested feature for gSender, mostly for people who fabricate PCBs.

I own a NWA CNC that has what is called Virtual Zero in its function. You use it to scan and set up you “Z” as you would when changing a tool. It maps the surface of the material and changes the “Z” componet of the G-code so that it will map the G-Code to follow the surface of the material. Thus you can carve a flat design into the face of a canoe paddle if you would like. Or I have never needed to tram my machine because I have mapped my work surface applied an offset to compensate for the differences in the surface of my machines bed. Hope that helps with what function I’m looking for.
You are definitively not trying to ‘tram’ your machine. As mentioned, you are talking about surface mapping and as also mentioned, this is a feature that has been requested but has not yet been implemented. I don’t think I have ever heard anything along the lines of ‘we are working on it’ so nothing can be said about when we might see this feature.

That would be useful to have if you have the object but not its 3D model. If you do have the model, Vectric vCarve allows you to project a flat design to the surface of that model.
It could also be useful in reverse: do a height map of an object and export the results to a 3D mesh.
Sorry for the long delays in my replies. I’m new to this site and they are limiting the number and amount of replies at this time. My spindle is perpendicular to the bed in the general sense. But the bed will change over time. If you do a quick 5 point or more Z mapping of the bed you can then run your g-Code through a Z height compensator to thus eliminate the need to surface your bed. Thus eliminating the need to surface your spoil board. I do make PCBs and for that work I put a waste board down on my table for each job. That fresh surface is zero for the area of the PCB not only giving a flat plane to work from but also a backer board that gives a clean hole when boring the vias. I’m looking for a similar function that I have on my NWA Shark machine so I don’t have to surface the bed.
