With that said, running at 60 in/minute, I get a usable part in 10 minutes.
3/4" diameter, 3 inches long, cherry dowel I make myself If you don’t it tends to move a bit.īeen running some small parts I use for the last couple of weeks.
I also use the stock end stops to trap the X axis on both sides at the radial line on the stock. Still working on a cambam postp for Marlin, not enough hours in the day issue. For an existing STL, I use CamBam with the Unroll plugin to generate a flat STL and import it. In the CAD/CAM designing for this, it is setup with the X dimension as the circumference of the stock. The City of Ninnescah is located in the State of Kansas. I have the parts to setup a switch system, using 2-4DPDT switches to disable X2, and turn on the rotary, just haven’t had the time to put it together.
( RATTMMOTOR Reducing Ratio 4:1 CNC 4th-axis A-axis Rotation-axis, 4 Jaw K02-63mm Chuck)Īs a 4:1, I had to set the steps/mm in the firmware for 244 steps/mm to get a complete 360 degrees. On the Marlin firmware, with dual endstopsĪbout 4 months ago I bought a smallish NEMA 17 driven 4:1 rotary with a chuck off Amazon. My 2 cents, I have a rotary 4th I am using.
