The controller is intended to drive rotary table, lathe head indexer etc. Allowing easy, error free division without the use of division plates.
As well as division the controller allows movement by angles (0.01 to 360 degrees), continuous motion (for machining), positioning (jog mode), a simple gear cutting mode and a sophisticated program mode which allows complex sequences of movements and events to be executed.
Input is via a 16 key keypad whilst a 4 line by 20 column LCD display provides information in a user friendly format.
- Jog mode. Keys move CW/CCW in 0.01, 0.1, 1.0 and 10.0 degree steps.
- Division mode. Divide a circle into any number of divisions (including primes) from 1 to 9999 segments.
- Degree mode. Move any number of degrees between 0.01 and 359.99 in 0.01 degree steps. (Accuracy depends on mechanics).
- Continuous mode. Table is driven continously CW/CCW at one of five speeds.
- Gear mode. Can drive a cutter and indexer on two ports to automate gear cutting.
- Program mode. Allows complex programs to be entered and run (storage for 10 programs). Ideal for production runs.
- Configurable for most worm sizes. (Specify number of steps per 360 degrees. i.e. 200 step motor in half step mode and 90:1 worm equals 36,000 steps per revolution with 0.01 degree resolution).
- Five machine profiles. Setup can hold profiles for five machines allowing device to be moved between them.
- Automatic backlash compensation.
- Can handshake with other hardware.
How do I get one?
There are three main ways to obtain one.
Build it yourself.
In the downloads section of my site you'll find the plans, PCB layout, component list and .hex file containing the firmware.
If you need it then I can provide the PCB, the PIC pre-programmed along with a set of parts.
The controller will work with any 4x4, 8 wire keypad or you can purchase a keypad from me.
If using my keypad (or a keypad with 0.8" spacing) then you can either make or purchase a front panel overlay for the professional touch.
Buy the module but provide your own case etc.
In the shop section you can buy a built and tested module and optionally a keypad and front panel overlay.
These require a suitable case drilled to take the module and keypad.
If bought from me the keypad simply plugs into the module and it provides screw terminals for connecting to a stepper motor driver (just 3 wires between them for the simplest case).
If you want to see what's involved take a look at the 'HardwareManual.pdf' which should give some insight into the internals of the case, also 'FrontPanel.pdf' has a drilling template and provides some details on making your own overlay.
Buy the controller ready made.
In my shop you can buy the controller ready to go. It requires a 24v power supply which can be easily sourced locally. It's provided with 2m of cable and just needs hooking up to a stepper motor.
Full details are in the document 'HardwareManual.pdf' in the downloads section.
Any questions either email me (my email address is present in most of the documentation) or use the 'contact me' option under 'About' on this screen.
