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?

I finally managed to sort it out and update my .ui file to GTK+3. I wish there was a better guide for the various LinuxCNC-specific components and the migration necessary.

I would not, unless it is really required.

Ahh, I missed that

As far as the spindle speed changing goes, it would probably be helpful to
disable the PID/feedback, in case there's something odd going on there.

Disable the feedback by setting all PID terms to 0 except FF0 so the
PID component is just a pass through.


Another thing for debugging would be to dump all the hal pins when
things are working correctly and when misbehaving:

halcmd show all > ok.txt

halcmd show all > bad.txt

and post the results here.
 

Yes that beautiful thing has been moved around to different places and has grooved well over 10,000 pairs of drumsticks (200k+ in gross sales) in nine years with no issues. Never had a problem with the software or anything until just recently. I know it’s an old version but it’s always worked. It’s just having a few issues. I may need to just upgrade the whole thing and start from square one.

Has it ever worked?
Why LinuxCNC 2.5? That's really rather old.

Can you post your hal/ini files?

Might help with more eyes looking at them

 

I found some configs posted earlier in the thread: forum.linuxcnc.org/26-turning/52640-old-...-cnc?start=60#326830

Thanks rodw, I will add that note in with my install disk. And also Thank you to all the LinuxCNC devs that
continue to make LinuxCNC possible.
