Hi Don,
I am an Old Timer and the process you describe will not gain you anything
except dropping the chuck key from one side.
I center parts on my lathe to 0.0001" all day long in a few seconds with my
4 jaw chuck.
Short Parts:
Mount the part in the jaws as close to center as you can.

There seems to be a rounding error in the Jog Speed: displayed by Axis on start
up.
I have MAX_VELOCITY = 5.0 for all axis
If I set
[TRAJ]
DEFAULT_VELOCITY = 0.1
I get the expected jog speed of 6 in/min and it jogs at about 6 inches a minute
If I set
[TRAJ]
DEFAULT_VELOCITY = 0.3 I get 18
AXIS uses an logarithmic relationship between the position of the jog
slider and the jog speed in inches per minute. At the left hand side,
the jog speeds are fairly close together (e.g., .001 and .002 in/min)
and at the right hand side the speeds are further apart (e.g., 296 and
300 in/min). The

Can you take a joypad apart and put into a more solid container and use
industrial
buttons so you can label the functions for input into EMC. The USB input for a
remote would be just too easy...
Thanks

Thanks guys,
I had altered the [TRAJ] MAX_VELOCITY and DEFAULT_VELOCITY a bit, partly
because I read in one of the recent posts that it should be more than
the individual axis MAX_VELOCITY, however, I didn't think I had changed
it so much and it then got pared back until all the axes would run
Hello,
I am new to both Linux and EMC. I am a maintenance supervisor in an
aircraft manufacturing facility. We do landing gear. I have a Motenc-Lite servo
board. I am pretty sure I won't have alot of problems with the motion control
section of this but was wondering about how to use a ma
Hi Dave
Welcome. This is a good place for help as is the IRC channel on
freenode.net.
There are both realtime and user space elements to ladder. The realtime
stuff does the actual logic while the user space stuff shows and edits
it.
Both demo_step_cl and demo_sim_cl should start a user space
Hi Ray,
Glad to be here. Thank you for the fast reply.
I can get classic ladder to come up in demo_step_cl and
demo_sim_cl. I guess my question is more about the configuration files for
Motenc card. When I look at the moten_io file it reads:
# Just uncomment the following lin

We must be thinking the same..Scary thing is was I went looking through

Glad to hear it's going. You'll need to add in the HAL pin links that
connect estop and lube so that the demo works properly. You should also
comment out the part of motenc_io.hal that loop back the estop.
You could use the program halcmd to link buttons in tkemc to signals

A quick question (one of many to come!),
would I change the line:
# Just uncomment the following line if you want a Software PLC
#loadusr -w classicladder --nogui ../configs/common/bridgeport.clp
To:
# Just uncomment the following line if you want a Software PLC
#loadusr -w classicladder --nogui

Thanks Ray,
I will hopefully be working on that over the next few days.
Still building the panel (Gotta make it look good as well as work good.) So
far I am making progress and thats good. The goal is to get this up and
running so we can decide wether to put it on production mac
Thanks, I will check that out.I do have a spare encoder channel on the
motenc. Do I not worry about connecting the "Z" channel. My MPG is a real
MPG. It has A, not A, B, not B only. No "Z" channel
