When you say micromill are you referring to the X2. I have one of these
as well. I am running it with EMC2 though the parallel port with a G540
driver. It accepts a VFD PWM signal and has an op-isolated 0 to 10 volt
analog output for a VFD. It also has 2 uncommitted output pins. It looks

Hubert,
The term PWM as discussed here is referring to the
signal from the parallel port to the device used to
set the motor speed. In the case of the X2 and
many other DC motor drivers, the current supply
into the motor is also controlled by PWM, but it
is generated and controlled by the motor d

How recently was the parport fix added? Is it in 2.3.3?
At any rate, I will send you the access information by private email.

I think the X2 is this ones bigger brother, selling for about $500, this was
the $300 HF version. But I bought the expansion table kits from Chris at

So you have the X-1, I have an X-2 and X-3 also from Habour
Freight. I am guessing the principles are the same but I will need to
check the implementation. Specifically, I am interested in what you

connector. Specific

Oops, yes. Thats what you said. Differential impedance = 100R

Hi Hubert,
You need to be careful connecting to the pot inputs of a lot of these type of
speed controllers. The usually put a DC voltage of anywhere between 7V to 15V
across the potentiometer. The kicker is that this voltage is generated via a
zener shunt regulator and the control voltage is ac
Hello everybody, this is the first time i use the mailing list so i hope i
could ask my question well..
I'm trying to make a simple lathe machine config with the two Z and X axis,
but i want to add two extra independent linear axis.
I think that i need to make my own kinematics file, but i need t

The SX3 or Super X3 sold by Grizzley (G0619) does use the digital
control. The X3 sold by Harbor Freight and also Grizzley (G0463) use a
speed potentiometer. My first attempt will be to use the VFD outputs of
the Gecko G540 which provides an opto isolated pwm to analog reference.
