3.5Nm NEMA34's.

Had to open the ends of the bed out a bit to clear the nuts but only for ease of taking apart/putting together. Had to grind some metal away below the bed to get the full X travel.

The Gibb strip adjusters were horribly loose and prone to adjusting themselves. I added a fine adjustment with pinch bolts to lock them in place.

I haven't tried it in avengeance yet, been pussy footing about with sub 8mm tooling. When I think about ripping off the excess with fat cutters at high rates I start to worry about overloading the ER32 chuck vertically. If the tool slips down the job is scrap. Even if it doesn't slip the column will bend deepening the cut and forcing a seperate finishing pass if the tolerances require it. Makes me cautious.

Rule of thumb for DOC is tool radius but I won't go >4 or 5 mm, OTOH you won't get the column flex I do. I think you have to find what the mill likes, it should purr through the metal like it wasn't there, hammering or screechy noises are a sign that you've got it wrong :naughty:
