I have seem some are not using the tracks/aluminum parts from farmbot:
I’m a bit confused about the correct size:
If I download the step model and import in into FreeCad I get a profile of 15x15mm but if i’m looking at the v - wheels docs it says you need a v slot profile of 20x20mm.
I seems that 15x15mm v slot it not so common. Is there a better list to source the alu parts in Europe?
