Hi,
I have just installed a new twin parallel port card in one
of my linux boxes to start playing with servos. Can someone
please remind me where I can look in Ubuntu 8.04 to check
that the ports are working and what their addresses are? Thanks.

Does anyone know which ER capable spindle/motor is the best cost
effective replacement for the Kress as shipped with Isel CNC?
I want to move away from the restrictions the custom Kress collets
creates and nee to replace it with an ER capable spindle/motor.
Hi,
I've got access to a 3-axis-mill that uses replacable milling motors.
On disadvantage of them is that the used cutters are hand-placed thus
vary in length.
Now I was wondering - is there any chance of using the gcode for probing
and dynamic tool length compensation to enter a

Hi
I have another pic http://www.conceptmachinery.com/Sh11.jpg

X pos-cmd commanded position.

Xpos-cmd commanded position and it parallel to Xpos-fb.
That what is should be?
X output begins ok but ends wrong. Think X output should looks like trapeze.
What need to change to
Xoutput is again saturating at +1. Did you check that the +1 level is
OK, and it shouldn't go to +10 ?
If +1 is the correct limit then you are simply asking for too much speed
during the cruise-phase. Lower MAXVEL until Xouptut stays below +1
during the cruise-phase (maybe at 0.7 - 0.8 or

Hi
I reduced all:
Default_valacity =1.
Max_velacity =2.0
Default_acceleration = 2.0
Max_acceleration =3.0
I reduced most of them by 2-3 times and graph looks good. I will post it
in 20 minutes.
I am interesting why my drive can not output more voltage?
power not enough? It is SD-94 8 amp
Please excuse a short commercial plug
Dave Engvall gave me a Panasonic brushless motor at the CNC Workshop to
see if I could figure out how to run it.
It took me a LONG time to get around to figure it out, but I have
finally got it! It has a serial output that contains the commutation

I am out of my league here, but I had Jon's new brushless amp in mind.
