Can you post a link to the controller and the exact DM542?

Thread: Gib missalignment

Many thanks for all your support guys, much appreciated. I decided to leave it like this for now, untill I make a new jig, just to machine the gibs. I will probably use the ball endmill technique described in one of the links.

I have a further question regarding rigidity. Is my thinking this is compromised right now correct, or not really?

The roughness is probably just the very end of the channel. Worth noting that the gib screws on these are often the cause of problems, forcing the gib at an odd angle.

Thanks MikeK!

Perhaps some more info re how you went about it and pictures if possible might get some folk on here to have ideas about what went wrong.
I see there is a thread about these here

I machined a 60° angle, just found out today it is supposed to be 55°.

Blimey! Where do you begin with dovetails cut like that. I'd be doubtful if you'd get any improvement without re-machining the sliding surfaces. Sorry to be so negative, but I think you've got a bit of a Friday afternoon mill there.

I also have distinct feeling this machine was made Friday afternoon just before Chinese new year after a few glasses already.

I second what MikeK has said. I've just been through this with my X2. I machined the gib screws to a point which improved things a lot.

Will give it a try. Some prefer pointed gib screws, some say flat, I checked mine and they are flat. What about rigidity? Increasing it would be my goal. Also reduced friction, but that I already got due material combination.

I have no idea why pictures do not show.

Hello.

I have made a new brass gib for my SX1 mini mill.

They look bad and contact only on two lines and not 2 surfaces. Why did this happen?
