Your Z looks like a big improvement. I was thinking you could
replace
the round column with a square one like this:
Hi list,
I am temporarily running my mill without a home switch on Z axis.
Travel is set to -4 , 70
In AXIS, if I accidentaly press home in the wrong place, say 80, how can I
jog past my incorrect home position towards the real home at 0?
The only way I have found so far is to restart AXIS.
Doug,
Keep in mind that the Oz In numbers for steppers are holding torque.
This number is pretty much useless as it is a steady state or a not
doing any work number. Take a look at automationdirect stepper motor
charts for some real info on torque and speed.

Kirk, Is there some built in device in the xylotex board that will
provide protection for the computer from Surges that might return to it
? I have read this can be a problem.
The text on this site does not say optically isolated so probably this
device isn't.
It might be more like a digital buffer. The advantage of opto isolators is
that they break the ground connection between PC and motor driver.

Take a LiveCD with you and pop it into the drive and boot up and to a Latency

If your going to use software step generation the lower the latency the better.

Nope, it's not configurable in this way. Everything has a keyboard

Yes, the data sheet mentions phase angle control applications,
so it is the style that turns on immediately, vs. the style that
waits for the next zero crossing.

Some SSRs are designed to ONLY turn on at the zero crossing of the AC
voltage.
The others are usually called random turn-on, meaning that they turn

Regardless of the type of turn-on, once the Triac is on, it won't turn
off until the current through it goes to zero - even if the LED is off.
That's why SSRs only work for AC - in a DC circuit the current won't go
to zero.
