I'm watching the table. I know the jog is working as if it were the tool
but my mind seems to want to think in terms of which way the table
moves. Also, the inconsistency between the XY axes and the Z axis often
confuses me (i.e. the arrow keys work reversed w.r.t. the table but the

Put this line in the file ~/.axisrc, with no whitespace at the beginning
of the line:
bind_axis(Right, Left, 0)
Create the file ~/.axisrc if it doesn't exist yet.

What I like about linear motors is the non-contact, low maintenance, no
backlash, high speed, and high accuracy. It may be overkill, but I like
that. The extra speed may be useful for thin soft materials and reducing
slew time when cutting lots of holes. The extra accuracy may be helpful in

A major obstacle in the way of using EMC for waterjets is slowing down the
cut in the corners to allow the jet to straighten out. Do you have a CAM
program of some sort that does this already?

Have you priced linear motors lately? They do sell them by the
foot, because either the windings or the magnets have to
Hi John,
Just a comment on linear glass scales.
Acu-rite does make the ENC250 series in the lengths up to 6 m. with a
resolution of 5 um. Really on the edge if you want to control to
0.0005. Using a 2.5 um resolution scale would be better.
No idea of price but the SENC150 series goes for
Hi all,
Step one is now done; the pulsecoder is connected to channel 03
encoder on the stg board and it works.
400 counts /rev. This would scale nicely to 0.100/rev.
I have a nice front panel switch for X, Y, Z ,B. If I use B as a not
enable then the other positions select axis and
enable at
You do need multiple scales for pulse coder at .001,.010,.1 for touch off tools
or using in manual for milling.

if i read your request correctly
it would involve a 16 foor linear motor
and you'd have to be a major government to afford that ;)

Hi Todd,
The base movement. 0.001/detent should work but 1/4 that would be
better. I can add a couple more bits for
scaling; that should do it.

I have waterjet specific cam software to handle the feedrate ramping, so
that’s not a problem.
