Re: [mach1mach2cnc] $25 usb breakout board?
Can you point me to the breakout board you sell?
At this point, the biggest challenge is to obtain/ fabricate a Z axis
mechanism. Unless I hear of a really good deal on a complete z axis
mechanism, my plan is this:
1. build a z axis slide mechanism out of some parts I have. I plan to
cannibalize a mil surplus aerial surveillance film positioning stage
mechanism that has linear bearings and ground shafts. I see on ebay
decent looking ballscrews and mounts for about $80 that I could
incorporate into my design.
2. for a spindle, I see some decent looking water cooled ones (chinese
no doubt) in the $75-$100 range
3. I have some old steppers that may do, or I'll just buy one. To drive
the Z stepper, I'm open to suggestions
My Dahlgren SE 400 came with something related to the spindle that I
don't understand. I keep looking at it and thinking that maybe it IS the
spindle and is a pneumatic motor or something, since it does have an air
inlet. I think it must be an air solenoid used to raise and lower the
spindle. I'll post pics later today. Your friend probably knows what it
is. I'm open to any advice on this project. It looks like a nice robust
XY platform to start with.

- Does anyone know if there is a howto on connecting Pokeys and MPG to M3 ?
I am not getting jogging movement, although in Pokeys IO I see the pins
M3 version .035,
newest Pokeys SW, plugin etc.
Is the Pokeys Pulse Engine a necessary component to get MPGs to work for
The only way I got any movement was to map in ports and pins:
Jog X++ port10/1
Jog X-- port10/2
This works, but poorly.
Jogging is not smooth.
A switch connected to a Pokeys Input works, when mapped to Input1 in
ports n pins, so the plugin works.
