Have a look at carousel component included with LinuxCNC:
linuxcnc.org/docs/html/man/man9/carousel.9.html
And posts on this forum regarding it

Also, there was similar functioning system on those small lathes, forgot their name, but there are plenty here...

I will take the covers off and give this a try. Thanks man.

Something does not add up, google shows many of the same model machines with manual controls

So upload some pictures of the machine.

Also, are both servo drives powered from the same power supply?

I'm having the exact same issue. Everything worked fine yesterday and i came out today and i have nothing. All the green led's light up and locks in the on position when i try to start linuxcnc. I am adamant about ESD and EMI. The Mesa 7i96s ground is connected to earth and all my wiring is double shielded with no ground loops. Is it possible to get this board serviced or is i a doorstop now? The red light just continues to blink with the jumper in the up, up position and none of the green leds with light in the fallback mode. Ping is unreachable in up, dn and and in up, up. I am at a lose. Nothing changed except the date.

I had similar problems with my servo system, and solved most of it by tuning the servos better. A loose servo control loop will look precise and accurate, until you put it under load. Can you rotate the servos by hand, at all, when they should be "holding"? If so, retune them.

Yes, I now have the estop working as you specified and have verified that it stops the machine when the button is mashed (OPEN).

I'm on to getting my HY_VFD spindle hooked up.

Thanks to all who have helped on this issues.

Argh, @meister thankyou, it works now. Took a bit of googling to figure out how to do that.

For other beginners, what I did in the terminal:
sudo ip addr add 192.168.10.1/24 dev eno1
sudo ip link set eno1 up

I also added the following to the "interfaces" file in /etc/network/
iface eno1 inet static
address 192.168.10.1
netmask 255.255.255.0

Change eno1 to your adaptor name

If you are retaining the hydraulics, the question would be how are the hydraulic valves
that control position controlled and what is the position feedback method.

Sounds like the jogging setup in the hal file is not quite right
can you post your hal file?
 

Honestly, I would just add a  leaded 620 Ohm pulldown
resistor on the back of the breakout card and not make
any further modifications.
 

My guess is that there siginificant coupling of the plasma start transient into the step/dir wires
or perhaps a grounding issue.

If you use single ended connections, the step/dir wiring will be less susceptible to
damage from external RFI/EMI. Another option is to use shielded wiring for step/dir
(with the shield connected to GND only at the 7I96S end) 

Control panel connections :

net matrix_r2c2 matrix_kb.0.key.r2c2 => halui.spindle.0.stop
net matrix_r2c1 matrix_kb.0.key.r2c1 => halui.spindle.0.forward
net matrix_r2c3 matrix_kb.0.key.r2c3 => halui.spindle.0.reverse

Hello zmrdko,

I just found your great work with the easycat card.
I'm starting to play with it, and it works great for digital input and output. With 1 encoder, no problem.

However, with 2 or more encoders, it doesn't work... As soon as I change the "QUADENCS" value to greater than 1, I can no longer connect to the easycat card. I get an error with the "easynavigator" software.
Have you ever had this problem?
Do you have any leads?

regards
Laurent

Hey guys...
I'm using Linux for the first time for a lathe with a turret with eight tools, each in its respective position, sending an individual signal for each position and a turret locked signal.

Working cycle:
"Control system sends signal of tool change -->Motor running with positive rotating -->Toothed disks is disengaged -->tool holder disk rotating-->tool holder disk locating-->Control system receives the signal of tool holder disk locating and sends the signal of delay time of motor reversal rotating Motor running with reversal rotating -->Toothed disks is locked-->Delay time of"

I need to know if there is any component in Linux that supports this cycle, or if someone has already done something similar so that I can use it as a basis to create the tool change cycle.
