So the FPGA would not be able to handle sinking 12 mAmps at 12 Volts?
In other words, I would like to wire a 12 Volt supply to all of the SSR
+ inputs. Then wire each SSR - input to each FPGA sink socket on the
controller card.

As nearly as I can tell, Axis always jogs in inch units,
even in G21 mode, even when displaying millimeters.
Fire up Axis, F1 & F2 to get started, F5 & type G21 for
metric units, View -> Show MM, then F3 to get manual
controls. Select X axis, pick 0.1 jog increment from the
list, then click th
How is the COMP_FILE = file.extension used in the Axis mode of
operation? I tried creating a table (comp.fil) as follows to see the
results and get an idea of how it works:
-13. -13.000 -13.
-5. -4. -4.
0. 0. 0.
The appropriate portion of the ini file:

The FPGA is a 5 V IC. I can guarantee, wit

I looked recently and the code is there. Is anyone using it?

JMK & myself added it quite a while ago,
we tested up to the point that it works, without hardware though,
Thank you for the reply Jon. 5 Volts it is then. With the old
controller, there was a 6' long cable to the SSR's. Now the cable is
about a foot long. Just in case, do normally repair UnivPWM boards?

In emc2/axis 2.1, the units for incremental jogs are always the machine
native units (e.g., inifile units).
In 2.2, it will be possible to set the units of each increment,
including a mixture:
[DISPLAY]
INCREMENTS = 1 mm, .01 in, .1mm, 1 mil, .1 mil, 1/8000 in
While a better choice in emc

Sure. Uhh, did you already hook it up to 12 V? If so, does it
still pow
