Attached HAL Files

SSH and samba are security risks, hence usually not included in major distros.
They should be installed only by whoever actually needs them, and some security info should be digested before venturing into it.

The X-axis servo motor and drive failed a few months ago and I haven't touched the machine ever since. I finally got back to fixing the machine, but I want to make some tweaks to the tool changer.

Everything works ok, but I need to add a timing delay when making a tool change. The motor starts turning immediately as soon as you make a tool change, thus not allowing the tool changer to fully unclamp. This causes the tool post to move back and forth until it is unclamped and then it will do the tool change as it's supposed to. I'm sure if i keep running it like this something is eventually going to break or wear .

How do I add a time delay so that the control waits for the tool changer to fully unclamp, and then rotate to the correct position, and re-clamp.

I will attach my HAL files, I don't think I set it up 100% either.

Do you want Linux Mint 19.3 with LinuxCNC 2.8.4 ISO?
It uses 4.19.nn kernel, if i recall correctly, and it works a bit better on my older laptops and PC's.
I can try to upload to google drive, if it fits.

i have used mode 2 on x and z. they are working.

ok thanks

Which combination of cards do you have?

Oops should have read the title.

That's a fairly odd combination, what hardware interfaces do you need?
There is no standard firmware for the combination, but it can be built easily
 

There's 7I76+7I85S firmware for a 7I80DB but not for the 7I76+7I85.
I can make this if you tell me which version of the 7I80DB you have (-16 or -25)

Note that Sserial cards don't need any card specific support in the firmware.
(as long as there is a sserial port, any sserial card is supported)

The 7I76 has 1 free sserial port and the 7I85 has 5 free sserial ports.

Just did that and it seems possible. Now the next question, which bit file should i use for this configuration (7i80-DB + 7i85 and 7i76 with the 7i87 connected to the 7i76)? thank u

I was running this computer over a year on 2.9.x with no problems.
Anything is worth a try, new Intel card on order. It should be here tomorrow.

Do double check this, but it should be possible to just wire the 7i87 to 7i76 using a cut off LAN cable, the Smart Serial connector, info on exact wiring is on the 7i76 manual.

Where did you read that? I would really like to delete that as it is just adding to the "buy a RPI" sickness spreading all over the web.
RPI is NOT required to run, it CAN be used to run LinuxCNC, any PC can be used to run LinuxCNC and Mesa cards.

On the Mesa subject, i do have somewhere a working 7i95 config if you need one, without the 7i77.
As for firmware, please do not proceed without consulting with PCW here, you seem to be bumping into some fishy info...
And for next time, when you have a 7i95 and you need to add analog outputs, use a 7i83 as 7i95 has encoder inputs. That is if you do not need all of the stepgens and encoders and analog outs and encoders...

Hello everyone,
I have a set-up consisting of a MESA 7i80-DB connected to two daughtercards, 7i76 for stepper motor control + a 7i85 additional board. I would like to add a third board, MESA 7i87, to read some analog sensors.
Do you know if this is possible or not? Is there a LinuxCNC firmware for this configuration?

Hello, 

i am beginner and (so far I can tell right know) successfully got my pi5 running with LinuxCNC 2.10 (which I read is required to run a 7i95T).
Sadly pncconf has no template for the Card, nor the combination of cards. So I decided to give mesact a try which at least knows the cards I got.
for my understanding, I need a firmware file to flash on my 7i95T to make the daughter card addressable. is that correct?
After downloading the firmware of the card and saving to the mentioned folder I recognized there is no firmware on the Mesa website available for my combination of cards?! or am I missing something? <screenshot appended>
can somebody help me out with it?

 

If I understand the source of the hostmot2 driver correctly, it is limiting the acceleration and also the driver does the encoder scaling.

This will make the firmware a bit more complicated, but I really want to use the original EtherCAT source already in LinuxCNC, and not develop a driver. This HW should be plug-and-play
