4th Axis options?

[Andrei]

I drew up and made a 4th axis using a hollow shaft ER32 collet chuck had two backplates threaded to fit to use either a 3 jaw or 4 jaw chuck and it works great.

Thanks .

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) and a sophisticated
program mode which allows complex sequences of movements and events to be
executed.
Multiple controllers can be connected together to allow sophisticated machining
operations – e.g. automatic gear cutting, one controller dividing whilst the other
moves the cutter.
Input is via a 16 key keypad whilst a 4 line by 20 column LCD display provides
information in a user friendly format.

Features.
• 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 from 1 to 9999
inclusive.
• Degree mode. Any number of degrees from 0.01 to 359.99 in 0.01 degree
steps (note: actual accuracy depends on mechanics).
• Continuous drive. Table is driven continuously CW/CCW at one of the
(selectable) 5 speeds.
• Program mode. Allows complex sequences to be carried out. (Up to 10
programs can be stored)
• Configurable for any worm drive from 1:1 to 9999:1.
• Five speed settings.
• Configurable for all common stepper / driver combinations.
• Five machine profiles.
• Backlash compensation.
