All the "professional" CAM software is Autodesk.

its barely in the top3, probably mostly because of the free fusion option, and they bought their way in with the others. fusion360 is basically a clone of mastercam but with tons of bullshit added. The professional cam software is mastercam, 3d systems and siemens, and autodesk barely makes the cut

Why do you want to update?

Works 99% of the time!
(Literally)

These crap HP PCs in my school sometimes randomly decide they have bad RAM or that their firmware is corrupted or something.

(HP stuff is garbage)

Turning them off, unpluging them, and plugging them back in fixes the problem every time.

Never buy HP unless you really need to for some reason.

Some people are lucky and got a lifetime license.

Others are not so lucky.

Though Autodesk's lawyers are currently searching for loopholes they can use to make you pay for a subscription.

Wait, does the OP mean a dual-boot or LinuxCNC on Ubuntu?

Was the scrap yard AIM (American Iron and Metal)?

AIM is a Canadian company.

Scrap yard usually resell working machinery as machnery to make extra money (and help the environment).

BTW, thanks for helping!

I have limit switches on the Z-Axis, lower and upper. I

1. Jog positive and trigger the upper limit switch
2. Jog negative off the limit
3. "Zero" via the UI the Z-Axis
4. The W54 Z-position will "reset" to a non-zero number
5. The absolute machine position does not change
6. repeat 1-4
7. The "zeroed" W54 position will increase by around .300 with each jog cycle.
8. The absolute position remains the same for the Z-position I am zeroing.

 

At the moment, rotorhoming starts when i power on the machine.
The problem is that i want to home the z-axis first.

Howdy all,
     I am working out the high level architecture (and ordering) for a Ethercat retrofit of my CNC Mill ( its VFD is dying and its as good an excuse as any to re work may decisions I made on it when I converted it to LinuxCNC the first time).. 

Anyways, I am looking at the MPG and realizing that I have open IO pins on my pi (like all of them).

So here is my current "plan" for I/O which I would love feedback on 

1x EK1100 - Ethercat to FieldBus coupler
2x EL1819  - 16 inputs (I need 28 so 2 it is) - (the response time is killer vs the EL1809)
1x EL2819 - 16 output (need 11 so that works)
1x EL5151 - Encoder for the MPG  <-- this is where I would love feedback because this guy is $250 used

The really open question is what risks on integration and general PITA am I facing if I use my Pi's IO pins to handle MPG encoder rather than the spendy EL5151. 

I plan to use either Leadshine or Innovance mult-turn servos for all of my motors and spindle so my only current known need for an encoder is the MPG...  This is less a question of "can I mix Ethercat with Pi IO pins" and more a question of "should I"... Am I setting myself up for sparks and pain getting the realtime thread where the Pi IO will come in syncing with the rest of the system that is all running on the Server Thread? 

To that end, should I be using other parts of the Pi's IO for emergency stuff like e-stop? 

Thanks in advance. 

You were right: The servo had a slave id o as well as the ek1100. I fixed that. The error msg seems to stay the same.

I can`t really understand what`s going wrong

Can you give a bit more detail about your system, and what problem you are trying to solve, and how this will achieve that?
By "planner" I assume you mean the trajectory planner?

I am now even more confused about what's going on.
Are you actually hitting the limit switch? Or do you mean that you jog to the top soft-limit, zero the coordinate system, and then jog away again this inexplicable offset appears?

Do you have anything like external offsets enabled? Any unusual kinematics?

if you want to try i added dedicated hal pin to the spindle encoder index, you can connect it to any input pin, and you can define in the config.h and also set the active level of the signal to active low or active high.

If the original manufacturer thought that is was important enough not to require homing to go to the trouble of fitting potentimeters I would be inclined to follow their lead.
I don't think it's a difficult thing to integrate.

I see you have two slaves with idx="0", that won't work.
List the indexes with "ethercat slaves"

There is another debug option or possibility. The output of "sudo dmesg" show a lot, at the end it may have info that can show the error.
Especially info messages from ethercat master and lcec goes there.
