Will do, just waiting for my bonus to roll in.

“I am curious to see how that whole table being aluminum has been done.”
Nothing fancy. Two solid core doors as a base with a gap in the middle. Topped with mdf, surfaced, mdf again, surfaced again, then screwed the plates down.
All holes are in line and straight within .003” and table is flat all over within .007”.
By the way, another cool thing about the pwn rotary is that it has a super long power cord so you can mount it to a nearby workbench and have a spinny contraption for whatever off the wall idea which would require a spinny contraption.
I didn’t even think of wall mounting, although it’s impractical in my situation… good idea, and it got me thinking about mounting on the side. Currently, I store mine under my table tailstock in first on the far side. I could do headstock first (as said, the cabling is generous), but it’s how i stored it from the moment i got it, and I’m a creature of habit
How hard do you think it would be to wire some of the SA12 connectors on the motor side of the power/stepper wire so the wires can be left in place and just the motor/tailstock be removed?
I haven’t played with sa12, but the pin out makes it look easier than gx12, which i have done.
It would depend on your competency. I’m fairly competent with a soldering iron and it would take me maybe 5 min to do 1 connector… Daniel has done a lot of soldering and would have it done in a minute or 2.
Going to give it a try. I just finally ordered mine tonight.

Just got mine this week and noticed a couple things while starting to set it up. The dimensions schematic on the KB here shows a 3 jaw chuck, which I am not sure super matters but just throwing it out in case you want to update it. Also I am curious the general thoughts on if having a wobble in the wheel that the belt wraps around will have a performance issue. I havent gotten a chance to full set it up I just plugged it in real fast for an initial test and jogged it back and forth and noticed around an 1/8 wobble in the wheel. I think it jumped around a bit in shipping as the box was fine but it wasnt seated in the foam packaging when I opened it.

I dont want to start any fires. I chucked up a gauge pin and about 1.5’“ from the jaws I have .002” runout which I think is ok. I also think my eyes were misleading me as the wobble wasn’t as bad as I initially thought. When I went to measure it I was only seeing about 16 thou variance.
I am working on making a mounting pattern now in case anyone in the community wants it. My footprint is slightly different from the measurements on the KB. I also am working on making it completely “modular” and will have plug options at the motor itself.
It wasnt about starting fires.
Is it possible that your guage pin or the installation of had the variance your seeing. I at least had trouble getting my zero and it took several attempts using a 1/4" aluminum rod… but now that i have it I’m not worried about it.
If you send a ticket for the drawing though, it might get fixed. (imo low priority, but if you don’t bring it up… no priority)
Question for the forum as I have submitted a support ticket and the suggestion was to post it here. I have my rotary all wired up now and have moved past the “does it spin?” stage of testing. I am using a Masso on a Onefinity and using the GCODE G0 A360 the rotary spins right about 2 times. It might be slightly less like 1.9 rotations. I have attached my masso settings which look to match the docs and my dip switch settings.
When I first got it all of the switches were ON or flipped in the direction of the belt except switch 2 which was off. Doing the above GCODE made it rotate over 11 times. That prompted me to look at the switches which made me wonder since it was the exact opposite of what the docs and settings in this board show. Now after fixing them it still rotates too much. Im a bit confused how its possible unless the steps per rev is wrong or its not a 1:6?
You got a head scratcher there.
Did masso register a 360° movement?
What i would to is mark the rotary head and the flat part with a line using a pencil (you can rub it off). Then do it again to see where its at.
I just double checked my settings, and they match yours except i have invert direction, which wouldn’t resolve this issue. I didn’t pull the motor backpack cover off but i trust it’s set for 10000 ppr.
If you didn’t get a 1:6 you can play with the ppr number until your lines line up.
Welp its my own stupidity. I was using G0 A360 and A-360…I didnt realize I was in G90 not G91 and Ill be honest in my haste since I had to leave for errands I didnt check the actual readout of where A was I was just clicking run then counting the revolutions. All is well.
I went fully modular and created this motor cover with integrated SA12 sockets so now I plugin on the masso side and plug in on the rotary side.
Noice. I love the idea you’ve shown here.
Good catch on absolute vs incremental positioning. I was racking my brain but wouldn’t have come up with that without additional clues.
