In order to print with the rotary axis, you need to follow this guide precisely. It will seem cumbersome at first, but will not be difficult after a few tries. Much of this will become automated as the Web Control is further developed.
- Create your model with an internal diameter equal to the mandrel on which you will be printing. Then, create a slot of 0.002" thickness in the XY plane, on the -Y side. This should go along the entire length of your part:
- Open the Diabase Printing Wizard and select "Rotary" in the Geometry section. On the 3rd screen (see below), add the .STL file from the previous step, and check the "Unwrap STL Files" box. Then click "Process via Simplify3D"
- In Simplify3D, you should see an "unwrapped" version of the original STL. Set the Y and Z offsets to 0.0. Then process the file as you normally would. Save the Gcode file, close Simplify3D, and proceed with the Wizard.
- Install the Rotary axis on your machine, plug the cable into the front-most sub-D connector, and click "Home All". If you need to make any Y-adjustment to ensure the tools are centered on the shaft, do so now by jogging the Y-axis. After this, the Y-axis will not move again.
- Find the X-axis limits for your particular mechanical configuration by jogging the machine with a tool selected and noting the limits. Type M208 Xaaa:bbb into the box at the top of the Web Controller, where aaa=Xmin in mm and bbb=Xmax in mm. For example, if the end of your mandrel is at X=-180 and the tool just misses the collet at X=80, then type in
- Run the ROTARY AXIS macro to configure the rotary axis.
- The order of the following operations is critical. Doing this out of order may lead to damage to your machine. Specifically, the mesh compensation has to be done before setting the mandrel diameter, or you will crash the probe.
- Click Home Z
- Click Auto Bed Compensation (note: if your X-axis limits are inside of the probing mesh, then points may be skipped. This is OK. If you would like to maximize the number of probe points, you will need to edit your mesh settings in the bed.g file)
- From the Auto Bed Compensation pulldown menu, select "Probe Cylinder for Rotary Printing" and type in your mandrel diameter.
- Begin printing
