7i77 lost connection while encoder counts (PREEMPT-RT)

Category: Driver Boards

Its unlikely this is specific to the encoder but maybe to changing PCIE data

Did you check dmesg kernel log?

7i77 lost connection while encoder counts (PREEMPT-RT)

Category: Driver Boards

Thanks for your quesses. The encoder that is now connected is mikrocontroller that simulates the encoder to trigger the error as fast as possible. The controller uses the single ended mode of the mesa and outputs 3V. I looked up the datasheet of the encoder ic on the 7i77 and 3V is in the ic s range. on a second encoder input i have connected a rotary encoder, that uses the 5V of the 7i77. 
And in the beginning the encoder inputs were connected to a 5V glas scale.
We also tried the encoder outputs of an ESTUN Servo drive.
All gave the same (bad) result.

I see that logging the last line of executed code is already working, that's great, it will be very valuable information in emergency situations.

I have improved the vertical Qtdragon. It looks good in 3, 4 and 5 axes. If something is still not good, request improvement.

QtPlasmaC Error: "E word with no G70,G76,M66,M67 or M68 to use it"

Category: Plasmac

I was never able to figure it out. Especially since it only happens sometimes. Now I am just using a simple button in QtPlasmaC which works fine for my needs:

9 Name = LASER\OFFSET
9 Code = G10 L20 P1 X0 Y0 \ G54 G0 X17.0 Y151.8 \ G10 L20 P1 X0 Y0

Yes, it does, and the amplifiers are disabled as well.
Alright, if that's the expected behavior, I'll program it to disable the outputs myself.

Thank you!

You could possibly use the Halui pin "halui.estop.is-activated" connected to or2 comps to the pins to turn off the mist, flood and what ever other pins you would like changed in the event of an e-stop.

Does "repair" refer to the "repair broken packages" option in "recovery mode"?

Did you enable networking first?

I think that's normal?

LinuxCNC displays E-STOP, right?

Hmm...

Perhaps it's a rendering issue of some sort.

Upgrades sometimes break graphics drivers (especially for older GPUs).

Always check the list of packages to be upgraded just in case an upgrade could break stuff.

I'm no Debian expert; I have used Debian on one PC for LinuxCNC, but that's it.

I've suspended a new system. Before the computer goes offline and goes into the basement, I wanted to bring everything up to date again.

The repair was unsuccessful.

Adding external switch for emergency stop and feed override

Category: Basic Configuration

If you use an encoder for feed override, the counts would connect to:

halui.feed-override.counts

7i77 lost connection while encoder counts (PREEMPT-RT)

Category: Driver Boards

pin hm2_5i25.0.write.time did not change anymore.

Suggests this is a PCIE communication issue and probably
not related to 7I77 5V

It may indicate a grounding/EMI issue. Do you have an issue when
the 7I77 in not connected to the rest of the machine?

This is why i asked for a dmesg log as PCIE issues should show up there.

digital outputs remain active after e-stop

Category: HAL

Hello everyone,

I've recently noticed that my digital outputs remain active after an emergency stop. For example, the air used for cooling mist or tool cleaning doesn't turn off. Is this normal behavior, meaning I need to handle it in the program myself, or am I missing something? Below is my current e-stop configuration:

#########################################

net estop-ext     <=  estop-logic.and
net estop-out     <=  iocontrol.0.user-enable-out
net estop-ext     =>  iocontrol.0.emc-enable-in

Any help would be greatly appreciated!

7i77 lost connection while encoder counts (PREEMPT-RT)

Category: Driver Boards

Hi folks, 
i got a problem in a linuxcnc mesa card configuration. if the encoders of the 7i77 counts for a while, the 7i77 lost connection and linuxcnc stops working.

Most probably weak 5V power supply and/or encoder drawing more than 50-60mA.
Easily checked if you have a DVM with min/max memory, and measuring 5V at the 7i77 connector and at the encoder connector.
