Fixed Gantry small precision begineer project advice

[yasu]

Thats a great idea. I have intention to order some tooling that i could use for part of the alignement like a dial test indicator of 0.002mm and a precision machinist square but this simplifies the alignement by a lot.


But i have more doubts now. It wouldn´t be more hard to machining all these channels edges to tight tolerances of straighness same as a straight grounded edge?
Another question is what happen if a channel is a bit higher even if is 0.01-0.02, could it cause tilt? or it is removed by machining the sacrificial surface the the machine is assemblied?


The x and y alignement i have clear now but the z alignement not so clear.
I have seen a method of how a DTI is placed on the spindle and with the readings there are some shims put on the z plate to alignement. That way is it relevant that the column of the Z axis had to be machining to square tolerances and also the base plate to surface tolerance where it sits to have paralelism with the surface where it sits the rails? or it doesn´t matter and is just shimmed later?



I sent you a PM about the spindle mount Boyan.

I guess i should have started the thread on build log section, maybe i could move it
