I've seen some picture of the Syil DIY kits and noticed that everything is predrilled and threaded for fixing to the standard pickup points on the Sieg built machine.
Given the very precise alignment requirements for ballscrews published by many manufacturers just how is the alignment of the ballscrews achieved with this method, is it a case that the Sieg and Syil tolerences are so good (hard to believe!) that the Syil bits just bolt on or is there some adjustment built in to the ballscrew end supports/motors mounts and the ballnut block mounts?
That's a good question M100
I believe many users of these kits just bolt everything up where it goes and because it works think that it is fine.
I fitted one of Syil's first few kits and there was a lot of fine tuning to be done to move holes slightly
and even remachine some surfaces before everything was aligned properly.
None of this was too difficult to do but just takes some time and care to get it all good.
Main thing is just don't assume because you can just bolt it together that it must be OK
If you can be bothered have a read of this thread that I had about the conversion.
