I did some manual G-code to use a 4th axis rotary basically like a lathe.  The A axis doesn't have a homing switch.  It advances a specified number of turns as the X and Y does its thing.  

Part gets changed out, repeat.  

What's the correct G-code to reset the A axis?  Numerically, it's spooled up like 1000 turns in one direction.  Moves aren't relative and I don't need the thing to unspool 1000 turns to get back to the absolute A-axis value the next G-code run will start at.

 

So, does it not respond to the home button? Is the home button greyed out?
Does it jog? Are the motors locked or free?

I don't think that counts mode _can_ work with a Boxford style of toolchanger as the number of steps lost when the motor stalls against the endstop is unknown.

It could be modified to work, but it might be easier to start from scratch as a single-sensor position-mode stepgen changer wasn't really considered when the component was written.

You could even consider doing all the control in the G-code subroutine:

1) Scale the stepgen so that a position shift of 1 is one pocket.
2) Connect motion.analog-in-00 to the stepgen.2.position-fb
3) Connect motion.analog-out-01 to the stepgen.2.posiiton-cmd
4) Connect the home sensor to motion.digital-in-02
(Actually, you can use any numberered analog/digital IO, you would probably use in, out and digital 00 in practice, but I made them different for clarity)

toolchange.ngc:

I have also overpowered the 5v side of a 7i76 board for a second or so. I saw smoke at S1 and driver chips etc.
Freight is too expensive to post back and forth to USA for repairs. ( In Australia)
Can you make up a component set that would normally be damaged? I'll buy another board and the component set...... to try to recover this board for my next project.

Looks like your network adapter is not upped correctly. The master can't access ethernet.
Check "ip a", it should say UP for the adapter but I guess it won't.
Follow one of the standard debian guides to bring it up, will involve the /etc/network/interfaces file.
Can be a permission problem, check "ls  -l /dev/EtherCAT0" should say crwxrwxrwx
Try with "sudo service ethercat restart"
Also check "sudo dmesg" the last say 50 lines for anything that can help.

Good to hear, wouldn't surprise me if you change D1 and D2 to X and Z.
That config should be enough to move the axis. Try it.
Then you need to add limit switches and other switches if you have that, spindle control, pendant or gamepad and so on.
Now when linuxcnc is up and running you can easily inspect pins' values using halshow.
The drive and motors are closed-loop I guess, then you will see actual-position change when you rotate the motor shaft, even by just a little if the motors are active.

I think the installation is fine. The system reports POSIX realtime, and the pins for testing are accessible:

Owner Type Dir Value Name
4 u32 OUT 0x00000001 lcec.conf.master-count
4 u32 OUT 0x00000004 lcec.conf.slave-count

When I now call EtherCAT Master, the system reports:

Master0
Phase: Waiting for device(s)...
Active: no
Slaves: 0
Ethernet devices:
Main: 80:ee:73:fd:0f:8b (waiting...)
Link: DOWN

The network adapter is correctly entered in Ethercat.conf:

MASTER0_DEVICE="80:ee:73:fd:0f:8b"
DEVICE_MODULES="generic"

The permissions are also correct:
'KERNEL=="EtherCAT[0-9]", MODE="0777"'

However, I can no longer access the EK1100. The EK is connected to the network and shows no errors. As mentioned, everything worked fine with the same components before the reinstallation.
 

They are enabled if pin 9 and 10 are not connected. So in default state with no external relays connected the drives are enabled.

When I short 9 to 10 they become disabled, disconnecting power to the drives and locking the driver.

I´ll measure the pins that come from the drive.

Hello Folks,

just a quick update: At the Moment I'm in the process of aquerring the machine. The machine was listed in working condition. But sadly it has an error in the B-axis servo amp. The seller is realy cooperative and tries to fix it asap.

In the meantime i was thinking about to major "hurdles":

1.) Milling spindle orientation

The machine can hydraulically lock the spindle via hirth coupling in 12 positions. This is of course quite importent for tuning tools and broaching tools. Of course i want to implement this feature in LCNC as well. The first solution that came to my mind is using a custom M-Code that executes a custom HAL Component.  The M-Code posting needs than to be implemented into the post processor after every tool change.

But i would prefer the solution by Mazak. They used iirc a custom tool change command and added the desired spindle angle.

It looked something like this: T01XX while XX equals the desired spindle orientation.

2. Turning spindle + C-axis + clamping I saw this is done via the PP so never mind.

There are plenty of examples on how to implement a lathe spindle + C-Axis in LCNC. What worries me is the spindle locking.
There is the INDEXER available, but this works only exclusivly with G0 moves. As soon as the G-code contains G0 CX and i.e. G1 CX FXX it does not work anymore. How can i solve this problem? My idea was to somehow use motmod.
C-axis can be locked if the next line of G-code does not move the axis and unlocked if the next line of code does. The question is how.

The bridge the waiting time for new posts on this topic here are some pictures:
 

Yes. 7i77 please

3D printed a lot of drone propellers, mostly not good or to heavy, but finally found some that are very usable, so guy named Logan on youtube, link to his video and files is on my video

Lots of mishaps went on there ...

I'll try to make a bitfile  tomorrow
What do you want on the parallel expansion port?
 
(Just  checked the first post so 7I77 on parallel port)
 

Definitely a better solution but I doubt time will alow for it now. 

I do think it is worth doing though, so I think i will set up a pc and ask a friend who is better skilled than me in terms of programming to have a look

Thanks Andy

Hi. Thank you for the support. 

I need to commect some io boards so i need at least 2 smart serial channels.

of the 8 available ports on the 7i94, can you provide uarts on 4 of them please?

Much apreceated
Henk 

did you run that through an AI to generate stuff?
