Slight problem with the Cartesian Bot 1.06 files

Not sure if anyone is maintaining this anymore, but I've been building up another Darwin, and I noticed that the new corner blocks have sharp external corners, but the Z motor mount still has a rounded inside corner where it fits onto the corner block.

Nothing a little carving won't fix, but I thought I'd mention it just in case.

Here's a photo:

Round interior corners are always good to avoid stress concentrations...

What material is that you're printing with, by the way?

Those parts are made out of PLA.

Yup, rounded is good, it's just that the old corner blocks had rounded exteriors to match; one of the files needs to be changed in order for the parts to fit together again.

Its the old problem of how to put a square peg in to a round hole.

I find it very Strange that a file was changed without the object being printed and tested before re-relese of a new file?

Can the files not be rolled back to the previous version?

If we make a new release, it might be an idea to rotate the X-idler bracket, since it prints upside down now. I had mostly printed it to find out that it should be printed in a different orientation. I was printing a set of parts and this was actually a show stopper for me, since I was unable to use the Java host and liked skeinforge better anyway. But I have no 3D CAD experience. Now I know how to import, rotate and export in blender. It wasn't too hard after all...

The same for the "corner bracket vertical bolt plug", which is also upside down. The latter didn't cause much 'damage' because it's a tiny part to print.

yeah, I've printed an entire Darwin, and most of the parts have to be rotated in Blender to fit, but all of them. I always check the part orientation with Meshlab or Blender now.

Thanks for the tip Wade. I would certainly be a problem that could fool me for a long time. The jitter in the connector would be more when the machine shakes, sounds like the conditions under which the problem occurs. I will add another capacitor to the stepper board and make sure that the connectors are clean and mate well.
So far so good:

I'm running it at 25 mm/s so that the problem would reveal itself quicker if it has anything to do with speed.
