I really can't understand why they use a stepper for this task. There is
no need for expensive stepper drivers and mucking about with allowing
for lost pulses. A DC motor works easily as well if not better. Here is
a video of an Emco conversion I did.

Hi again
Thanks for the various links and info, I will have to sit down and try to get
my head around them and work out the best strategy
John and Steve are correct about the way it operates.
It is a Boxford 240F and really it does not matter whether the motor loses
steps when locking back.

I wouldn't think this matters. Tool movement is relative not absolute.
You ask the stepgen to move +130 from where ever you are, then -40
till it hits a stop. The stop sets a new position and then you move relative
to

Hi All;
Can EMC do coordinated move on all nine axis in a
single move command i.e. G01?
Are there limitations that would require compound arcs shapes
to be converted to small step in a five axis milling machines?
Thanks
Don
Alex,
Your code has successfully driven my (not simulated) Puma560,
I'm having problems with the speed/accel. limitations (as they are axis
limits, not joint limits)
The only solution I have a.t.m. is to reduce the overall speed so no joint
limits are reached (works if no singularities come to

Hi All:
Being new to EMC 2 and g-code I have yet another question to ask. When you
do a tool change what's the best procedure for determining the tool length, and
then how do you communicate that to the g-code? I hate to admit this, but I've
been using the knee to adjust out the differences
Andrew,
Using the knee is a very effective and useful method to adjust for minor
differences in tool length - do not apologize for this. I have used it many
times.
EMC2 has a tool table with a column for tool lengths. The gcode can access
the lengths in the column and rows to adjust the tool
Thanks Chris;
The all axis coordinated moves will get me going and
the current helix capability will be a big help.

Hi All;
Is ENC 2.4.2 axis-lathe.ngc /Machine/Calibration working.
It only shows Tune 0 parameters.
Tune 1 and Tune 2 display nothing for me.
Am I missing something?
Thanks
Don
