Hey Folks:
I thought I had tool offset
figured out years ago. I have this simple project and it's driving me up the
wall. I can't figure out why my exit conditions and entrance are
not working. I'm running EMC2 v2.3.5 on Ubuntu 8.04. Yes it's obsolete
but the atom board on my mill won't run

Yes, your excellent work is just what I had in mind when he got his machine.
I remember coming across your work when I was working on getting my Bridgeport
Series I CNC retrofitted. Thanks for the help on that one too. So do I

Hi All:
I have a friend who just got a nicely working
Shizuoka with an old Bandit controller. Now I want to help
him retrofit from the 80's to today, but he's pretty leery
of losing his machine for a 6 month project. ... Not an
outrageous fear.
Does anybody know how of a way for EMC2 or a

Thanks for writing in. I'm just in from the shop. I made yet another part

I have too much work to do.
Like many of you, I also run off of a solid state drive. I would not go any
other way. I love the 2
Hi All:
Just when you thought you'd heard the last of this problem here it is again.
I installed the latest version of Lucid then aptituded my way to emc2. I

Indeed for the entire weekend I tested my machine running em

I'm making two parts both with the same outline. The bottom of the part is
coded to be along the line y=0.000. One part came out perfect, the other had a

seems to be the tool offset distance. So the carto

do it by hand up to a meter or so in diameter. It took a few decades to develop

I used to work at a large optical lab. I'm not sure it's as off topic as you
might think. There are papers out there describing how to control glass removal

Jon you understand me totally. You knew I'd want to embrace the maximal
complexity and make the problem hard. So what I REALLY need is a tip-tilt 4th

Hi All:
Now that I'm making parts on my Bridgeport, I'm getting greedy. I want to
make gears. I want to make more complex parts. I want a 4th stage. I'm thinking
of just using a small lathe that I retrofit with one of my spare steppers and

Hey Everyone:
I ran through the tests in the service manual that you folks said I should
do. My transformer outputs look good. But the quiescent AC current on each
stepper was set at 10.2A instead of the 8.1 - 8.4A called for. Why so uniform?
It almost makes me think that the previous owner p

Okay, so the question about what drives the current for the reactor control

Hi All:
My Bridgeport Series 1 is popping fuses on axies. I'm making a mount plate
and drilling a scad of holes. 160 to be exact. I have a stepping machine with
no glass encoder feedback. So it just counts steps and assumes the stepper
makes the step. I was lucky tonight in that the Z axis k
Hi All:
Thanks for the fast replies. Well my next interface PCB iteration will be a
probe input for touching off etc. I'll find out if my spindle is electrically
osolated, or grounded (hopefully that) then I'll use the manual tool change
routine. I guess until then, I'll just keep using the
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
Hey All:
Thanks for the fast replies. Hummm. I thought of turning off outputs to
the parallel port, but wanted something I could use as a fast test of
individual axes on individual programs. What I did do was comment out all
motion in the XY plane and keep all the Z motion. But that mean
Hey Folks:
I feel silly asking this question, but here goes. I ran into an issue using
peck drilling with the tool retract. The end result was my Z stepper was
missing pulses on the retract. So I've derated the max accel and vel on the Z
axis and everything looks good, however what I'd reall
Hi All:
So I'm going through the various g-code generators out there, and I have to
say, I'm not getting the greatest results. I'm using Alibre to generate my DXF
files. I'm just curious as to what you folks use any suggestions or insights?

I was looking over the emc2 site and saw someone post about a graycode
