Spent the last several days mounting an encoder to the spindle. had to get real clever here. Only got about 1/4" of the top of the hollow spindle exposed and it can't get in the way of the tool changer. The pics show the parts and the final completed project.
A spindle encoder really increases capability. It allows the spindle to be treated as a galil axis to control the spindle VFD. S codes for programming spindle speed are now a piece of cake. Rigid tapping can now be done. if a 4rth axis is added, it can be slaved to the spindle to hob gears. By comparing analog command voltage (Galil TT) to spindle speed, it is possible to determine where the adjustable speed pulleys are set.
