AndyUK's Build - 1.2x1.0m Gantry

[MikeyC38]

Hi Kit
On my build I wish I had given more thought to tramming adjustment as I now have to use metal shims to get everything right. Some sort of screw adjustment with a wedge may work. For tramming I could'nt get on with a single dial meter so bought this and I found it to be money well spent

Kind Regards
Michael

My machine is covered in shims! At least I built it in a way that makes it possible to access the places I need them easily enough.

I've seen the tool you linked to before but used a different method myself which was much less costly and used the Z axis DRO as a micrometer. This uses taught wires stretched between the long axis rails (X on my machine) to create the reference plane for aligning the gantry. This seems the best way to do it if your machine design allows it since these rails (once proven parallel) ARE the plane to which the other axes have to be parallel or perpendicular. Once that's all aligned then skimming the bed brings it into same plane and is the final job to be done. I wrote a thread about it last year and there's some updated stuff on my build log after I moved house and did it all again.
