Depending on if we buy this new printer for our shop this week, Im ordering one to get it working. My plan is to mill out a channel in the carriage that is just as wide as the focus adjustment arm, so it cant wiggle at all, but still slide up and down.

I'd like to redesign the Z adjustment mechanism altogether; I think a V-groove would be much better suited to the job. I'd arrange it such that a screw would drive the vertical part deeper into the V, locking it in place deterministically. The wedging action would help a lot in locking it down, and wouldn't take up much space nor would it be hard to redesign.

Though I do wish there was a way to get air over the TOP of the lens just to keep some of the smoke from settling onto it, but I'm not sure how I'd make that work (with the current system).

2 air pathways, 1 smaller. if routed right, it would work. if routed wrong, it would create a venturi and suck smoke to the lens.

Im willing to go slow. like the Admin, if this goes down for any length of time, thats complete suckage (and I would have to reserve laser time at techshop, and re-get a membership)

You getting the McMaster set, or were you able to find it cheaper somewhere else?

McMaster. Should be here Tuesday, their warehouse is about 45 min away from here. I was doing cleanup on the laser today, and getting frustrated at its construction the more I tear into the machine.

Hah, same here- I was working on some alignment the other day and was really getting frustrated with a couple of design choices.

Let me know how the rollers come out. If they look good I'll get a set in the next few days.

Fedex shows delivery. Will post up pics when I get home and unbox. Came out to 139 after shipping.

First impressions.

    -Someone dropped the carriage, it has a dent in the corner. Not acceptable on such a pricey part.
    -The wipes put a lot of drag. Enough that it wont fall when turned vertically 90 degrees. Take them off, and drop the preload a hair, and it slides nicely.
    -This one has a bit of hesitation at points. I suspect it might be related to the ding?
    -Rail looks like raw aluminum. Or really dirty. Wear gloves and wipe it down. For ease of maintenance, I might cover the steel rails with tape and give it some paint.



Off to email mcmaster and see what they say about the ding.

McMaster can be pretty silly when it comes to shipping. I once saw them pack a single sheet of diamond coated sandpaper ($40 a sheet) loose in a box with two quarts of paint...
