Hey Brad,

From the CNC machine’s perspective, it seems plenty rigid so far (needs more mass). The weakest link is the 80mm spindle holder. A more rigid design for steel there would give excellent bang for the buck.

Yes, this was often discussed here. That is why I think of replacing the entire Z assembly by a universal Z assembly . I am not surprised that when milling steel, you encounter chatter, which I would see caused by this.

The Universal Z assembly project looks very interesting. It doesn’t look like anyone has moved forward on it, but I’ll keep this in mind as I keep making progress. It’s something I’d like to do if I can find the time. I think I’ll pop a question into that thread.

besides in that thread, the Z assembly is also discussed here:

• Has anyone replaced their Z axis assembly for greater travel?
• this discussion
• 43mm Euro spindle
