I have a rotary axis I bought off of ebay.
It consists of a rotary chuck with stepper motor and a tailstock. NOTE: I replaced the stepper motor with a servo.
What was not included is a rail system to slide the tailstock to the work piece.
Where can I get one of these rail systems? It needs to be low profile as I do not have a lot of height for my system.
Here is what I have. I am using oak wood blocks to help clamp the system down. Its not very good and I have to spend a lot of time making sure everything is aligned.
A thought just occurred to me.
If I did go the route with the rails... I could do a cutout on the bottom of the wood. It would then fit the T-track outer edges and keep it lined up. The bolts could have a quick release handles. If there are any other systems out there that are better I would like to know. I have searched and most of the searches comes up with the rotary chuck and tailstock or the entire thing for another machine. :/
Thanks.
Same guy did this. He took his rails off and made a simpler setup.
I should do this till I can afford a much better setup.
I hope this also helps others who are DYI on the cheap.
Here is the video:
I had a machinist friend put the headstock and tailstock on aluminum plates. Bolts going through the plates fasten to aluminum 'feet' that just fit in the extrusion slots of my deck. So I just loosen the bolts and slide the tailstock up the extrusion slots. It works very well.
The headstock is almost always in the same place, so its XY positions stay in WCS #5. Because the center axis never changes, I modified one of Swissi's probe macros to measure bit height on the TT4 with a known, constant offset reference height.
In your case you'd have to swap A for B axes in your post processor to run along Y axis.
