Hi,
I consider purchasing 7i43 board to control 6 servo drives. First in
step/dir, later in analog mode (with homemade PWM to analog
convertors). As long as I have SPI encoders, I'm not sure it is that
simple to connect them to EMC2 for analog servo mode, but I hope it's
possible.
Some questions:

Probably. The bigger FPGA gives a wider choice of firmwares, there are
some functions that won't fit in the smaller one. EMC2 only supports
the parallel

I missed the bit where you said you were connecting 6 motors. Visteurs

By the way, DMM Tech has

You noted that you are using step/dir into servo drives - does it follow
that your servo drives require those SPI interfaced encoders? In the
servo drives I've encountered, if it has a step/dir mode, the drive is
an intelligent one and handles the entire PID and feedback loop itself,

To some extent my experience with hard drives has been random also,
however I distinguish two types of drive failures.
1. A soft failure where the drive simply starts having more and more
bad sectors and has to be replaced.
2. A serious failure lights out failure where all data is suddenly
How do I assign keyboard keys to manually jog axis A?
The standard assignment seems to be [ and ] however on my non-us
keyboard neither the keys generating [ ] nor the keys at the place where an
us keyboard has [ ] gives the desired result.
I thought I saw a post on the list of someone that had converted their
manual lathe to CNC by adding on a X (or x-y) table to the cross-slide.
Anyone have a link?

Probably the Omni-Turn add-on.

I think DMM are missing a trick by not outputting emulated quadrature

I am fairly sure that you can make a 7i48 do 0-5v, simply by limiting
the pwm duty cycle in HAL.
