The NCV7608s are quite fine with inductive loads up to their rated 350 mA,
but larger inductive loads must have a flyback diode. The NCV7608s can
also be damaged by excessive field voltage or switching the field voltage with
a mechanical switch or relay contact.

Also 29V is odd for relays and suggests an unregulated supply, which may also
be an issue.

The 7i77 card outputs use NCV7806 IC. These chips are sensitive to overvoltage and overcurrent. You can reduce the chances of frying them by NOT disconnecting the 24vdc supply side of the card to avoid overvoltage.  Use slave relay cards to avoid overcurrent.Have look at the attached picture.  Centroidcnc equip their low-cost CNC cards with hobby grade relay card and hard wire the dc supply side (I would solder the wires) to further reduce headaches with fried chips and provide an AC plug for power disconnections.Centroidcnc has been in the business of dealing with hobbits for long time, they know how to reduce issuance of RMA’s (PCW knows what I am taking about).

One of those should already work for the LED driver boards you have.

Please help - I am completely lost and have hit dead ends with the doosan post - I am now thinking it is better to start with the linuxcnc milling post or find a different post.

Do you think I should look for a post processor that handles 4th axis milling and limit Y axis output?

Hey great! Thanks for the real responses! I can appreciate the hate you guys may have for ChatGPT. I get it! I use it all the time for programming simple micrcontrollers. I knew that it wasn't quite correct. I put it there just as a thought. I didnt think there would be such an up-roar! lol I am not trying to be lazy. I just got lost in code. My brain says NO! I can build almost anything, except software!

That being said! I am a hobby CNC guy. I love these machines. I mostly build speaker boxes and I make random parts for my friends, typically for things that are obsoleted and you can't find parts. (Metal or wood) I have a Makino Lablonde FNC-106. It is a 20,000 pound absolute dream of a machine from 1988. It is as accurate as anything built currently (actually more accurate than some). It is a beauty! I also have a 1996 Morbidelli Author 502. I have replaced the NC with Mach and a Galil Motion Control. I has been good but recently, a rat chewed on some wires and fried the control card. I am playing with some ideas on replacing it on a budget. I just vbought a truck so I really dont have much to spare.

I do however have TONS of different gear around here to repurpose. I have several options. one was the parport idea. It was only a thought. Now the other thought that I have is an FPGA. I have several different FPGA boards. I am, again, just having issues with the software part of them. I have included a couple of photos of them. I think I can make the colorlight board work... With the DAC as well! I am just having difficulties. The other board that is by itself.... I think would also be a real good candidate. Anyone know much about Reverse Enginering?

Sorry for the delay, pictures attached, DC brushed motors with tachos, no encoders, encoders were mounted on the ballscrews.

As described in the hm2_eth man page, it involves adding the appropriate text
to the /etc/network/interfaces file, in your case, adding something like:

       auto eno1
       iface eno1 inet static
           address 10.10.10.2
           hardware-irq-coalesce-rx-usecs 0


You need to run the editor as root (with sudo) to edit this file

After editing the file its probably best to re-boot and then check if the
setting works with:

ethtool -c en01



 

Hi PCW,
the result with the ethtool is very sufficient:
 

So, do I have to copy this line in my .hal file? Or is there another way to do that permanently? I don't find that clearly in the manual doc. I'm sorry that I'm not a Linux pro but a newbie to all that.
Thanks, Arno

Sorry Klopp, i meant the video link by Spumco

Hi. I have the same problem. LinuxCNC 2.9.3 released did not solve the problem. Any news on this issue? Thank you/

Hey, everybody. I have the same problem. LinuxCNC 2.9.3 released did not solve the problem. Any news on this issue?

man hm2_eth

for instructions for doing this permanently

to test temporarily:

sudo ethtool -C eno1 rx-usecs 0
 

It's hard to find anything clear on Fanuc stuff, but I think the spindle amp uses serial communication to/from the Fanuc control.  So while it may be possible... it'd be non-trivial unless you can find someone who's done it already.

Regarding the C-axis aux motor, I just stumbled on a <shall-not-be-named> forum post where someone retrofitted a Fanuc lathe and added an aux C-axis motor.  They did, more or less, something I'd been thinking about for a bit: belt drive with dog-clutch.

centroidcncforum.com/viewtopic.php?f=57&...1&hilit=fanuc#p88931

Looks like they crammed the clutched C-axis servo in the main spindle drive belt path, added a couple idlers for belt tension, and just used longer belts.  Quite clever, and doesn't need a separate belt or gear drive.

@tommylight No, everything is german if I didn't miss anything

@RotarySMP They just attached adjustable cams to a bar, pretty standard I guess
