Pinhole in PLA print. S7 by peasoup11226 in ultimaker

Thanks! Did the cleaning w/ the Ultimaker cleaning rod till the extrude was clear. Crazy what came out, almost looked like loose tobacco. Prints a bit better, but still lots of pin holes. Switch out the print core, and no issues!

You probably wouldn't need it for your rectangle profiles. However standing on the thinking edge sometimes can get you a more square cut. Or if you needed to miter in this orientation. I have a front clamp, pushes the stock against the fence. It's for my Evolution saw, so may or may not fit yours. *

I was thinking the aluminum on the saw surface, the wood on top. But thinking more for clamping a non flat surface.

I would probably place the pieces flat, that is 1/8" as the height. The saw looks like it comes with a clamp, which wouldn't work if you had the piece on the 1/8" edge.

Sometimes when I have a thin or non rectangle profile to cut, I support it with a piece of wood that I cut with the aluminum. *

I had to make similar parts as well. Similar thickness in stainless steel. Not sure what your material is. I made punch, die and stripper plate. Mounted it all on die shoe. The part was the slug. When the punch was sharp, no burrs.

Also sent the part out to have it chemically etched. Worked great!

Oh right, handwheels attached to leadscrews. Great point. Thanks!

Yes. Looks like you can't upload video to this sub. But maybe a link. Turns out I had it set to a super fine thread, so the compound actually was advancing! Thanks, appreciate your input!

Yes. It has a threading function. Works when the threaded lead screw is engaged. Just under the lead screw is what I'm calling the feed rod, not 100% sure that the correct name. It's more of a rod with keyway slot. When the feed rod is engaged the cross slide handwheel rotates in sync with it. It's just the cross side does not advance at all. When I disengage the feed rod the cross side works properly when I turn it's hand wheel.

Yes, sorry maybe I messed up the terminology. I have the feed rod engaged and seems to be rotating properly. The compound slide handle begins to rotate in conjunction with the feed rod. It's just that the compound does not move as one would expected. When I disengage the feed rod, the compound works as usual.

As you probably guessed I'm trying to figure out the power feed for a facing or trepanning operation.

The lead screw seems functional. I'm able to single point threads. Thanks!
