Hi all,
I have a servo motor axis configured angular with a relatively low
resolution encoder / gear ratio. One revolution of the shaft is 19600
counts, or 54. counts per degree. I was having a very difficult time
tuning it at 54 counts per degree, so I set the counts per engineering
unit
Hi all,
Somewhat off-topic, but did something change at SourceForge, and is there
anything I can do about it? Specifically any email to this list from my
original registered email address is now getting bounced. The error message is:

Hi all,
I need some 24V I/O in an application already using the Mesa m5i20 controller,
and was looking at the 7I37. The inputs are obvious. As for outputs, the manual
only refers to 48V. Am I correct in reading the usage as whatever voltage is
supplied to the drains (OBITx+ or odd pins between
Peter,
>From the perspective of the m5i20, etc. they do not need to be isolated. The
actual BCD inputs are 24V, so I have to go through relays anyway. Thus TTL
(5V or 3.3) as on the m5i20 will work fine.

Hi all,
I have a project which requires interfacing to a laser having 2 x 8 bit BCD
inputs, which alone would exhaust the available outputs of the standard
configuration on the m5i20, and I need a few additional outputs beyond
these. I have plenty of inputs available, so a 24 / 24 split on inputs
