I use Synergy from Weber systems http://www.webersys.com/ for my

it. I ended up going for the total package. I found the people at
Weber to be extremely knowledgeable and helpful. The people you talk to

I believe in an earlier post that you had created some changes that

I am not quite sure of the math but you also might consider a 240V

as almost a break even choice when replacing large single phase motors

I see on this list that Limit switches are highly recommended. Not only
to identify mechanical limits of the system but also for finding the

I am a relative newbie to EMC2. I have a rotary table, and have also

Think about it. The linear will always be predictable. It moves
from the current position to new position. In linear absolute mode -180
is not the same as 180. If I were at between -180 and 180 for a move to
180 it would move CW, a move to -180 it would move CCW . If the

So you have the X-1, I have an X-2 and X-3 also from Habour
Freight. I am guessing the principles are the same but I will need to
check the implementation. Specifically, I am interested in what you
connected to pins 1, 2 and 3 of PMDX-106's J2, the spindle signal
connector.
with buttons for speed up/down and not suitable for accepting an
analog control input that replaces a manual speed potentiometer.

I measured the voltages across the potentiometers on both my X2 and X3
they are both Harbor Freight machines. The X2 about 15 months old and
the X3 about 6 months old. The X2 had 12 volts on P1, varying
proportional to increasing speed on P2 relative to P3. The X3 had 7
volts on P3,
I am actually working on two machines in parallel. An X2 and an X3.
The X2 already has LMS addon pulley set for spindle power. For it I am
thinking of just Drilling single hole on one side of the larger pulley
and sensing that as a index pulse and starting along the lines suggested
here
to determine which
size of FPGA to use. I think it will also allow me to use separate home
switches and possibly some control for a tool changer (dreaming).
Please warn me of pitfalls with this scheme.

From the drift in this thread it sounds like you have an X2 using
stock screws. In my case I abandoned the stock screws and went with
lower cost rolled ball screws. I decided the X2 wasn't rigid enough to
justify precision screws. Of course at 5 tpi I get plenty of

for both my X2 and X3 unfortunately I only found the 5/8 screws
reasonable. Yes the ball nuts are a major cost as I use 2 for each
axis. Nuts less than $25 each. I don't know how they would fit in

They still may be a type of step and direction drive card, or they may

Ok, old is 23 years the and motors sound like they are round so they
