Hello to all.
I need to control a screw with an encoder mounted on it. Calculating the
max rpm and the resolution I want I need a 25 khz read response for the
encoder.
I remember reading somewhere the maximum expected frequency of the parport
software driver to read an input but I don't remember

Hello Jon and thanks for the quick answer.
I was affraid that it would be on the limit. I guess I'm going to use a
5i20 to read it. I have one machine using it so I can test it with the TTL
encoder and see how it works.
Do you know if the 6i25 is already supported by LinuxCNC? I know that
I've made quite a few resin molds, I was working as a prototype technician
once upon a time and made a lot of parts in resin. We did both silicone and
metal molds, but we never poured the resin manually. I used a large vacuum
oven with mixing equipment inside, the internal dimensions were like a
Were you using aluminum? What type of draft did you use on the moulds?
This is the aftermath of the pressure tank test.

This is the static mix pressure test, not sure exactly why the top corner
bubbled.

How about trying a different resin? Call Smooth-On and see if they have
any recommendations that may fit your needs.
Or perhaps an epoxy might work better? There are many manufacturers of
those. One that looks like they have some interesting products is West
Systems.

Yes. Usually splitted molds or ejectors in the bottom that could be
manually knock the piece out. Another simple trick is to drill a small hole
and plug it with a tiny bit of clay at

That thing that looks like a small motor in serial.

I bought this tool changer from a guy who slaughtered a VMC.

There is a vid here with the changer before he took it down.

It looks more like an auxiliary motor to run
a cooling fan for the big motor. This is sometimes
needed if the large motor is under speed control
and running at low speed.
