Hypertherm powermax 85

If you have a 7i96s there, you should not even need a relay. Last time I checked the outputs were OK for 2 amps and nothong in plasma uses that much current. I used the Mesa 7i76e spindle on relay on my plasma machine for torch on and it worked perfect.

How to "connect" a hal to sserial at mesa 7i76e => THSW.hal Hand Wheel

Category: HAL

During some fault researchs I begin to get a bit more familiar with the structure behind linuxcnc.

In my case serial wasn't noticing the tshw. It wasn't listed in the Halshow. So linuxcnc was promoting the error.

Finally I found the error in the wiring to my sserial device (I built up by myself).
After wiring was correct it was noticed in the Halshow in linuxcnc. Now the pins are available and I know where I have to look for the right names etc (Halshow).

Thanks

Having problems with my THCAD-10

Category: Plasmac

the light on the board  shows your wiring to the thcad is correct.
Next step is to confirm that it is being read correctly by the mesa encoder.
open halshow and find the encoder you are using. Does the velocity pin ove at all or does it stay static.

If its static, then this is probably missing from your hal file.
setp hm2_7i76e.0.encoder.00.counter-mode  1
setp hm2_7i76e.0.encoder.00.filter        1
setp hm2_7i76e.0.encoder.00.scale        -1
I thought it was added by pncconf

When LinuxCNC is running and you expect the
spindle to be  running, type this in a terminal:

halcmd show all | grep spindle

and post the results here

Also measure the voltage between 7I76E TB4 pins 1 and TB4 pin 3

Spindle Drive 7i76e

Category: Driver Boards

Hi, we're 2 students from Belgium and our final project is to make a retrofit for a milling machine.
The 3 axes work fine, but we're having trouble with the spindle, the mesa card doesn't deliver any signal to the spindle drive.
We're using gmoccapy ver. 3.1.3.8 with Linux ver. 2.8.4 we're also using A2 Series VFD.
We can activate "left" and "right" on the gmoccapy UI.
How can we check what we've done wrong.

Thank you in advance for a response.

The above is for a mesa 7i76e interface card.

State tags refers to an information channel in linuxcnc that would, ideally, publish the current heading of the trajectory.
Alas it does not do that because nobody has implemented yet.

I started that. It would be worth resurrecting by somebody with better skills than I had

locale error: unsurported local setting on Raspberry Pi 4 was created by mistolt

locale error: unsurported local setting on Raspberry Pi 4

Category: PnCConf Wizard

Hey everyone,
After using Intel Nucs for my Mill, I thought I try it on the small Raspberry Pi 4 for my Lathe.
But I encountered a Problems in the PnCConf Wizard.
Step bevor error:
Install the newest Linuxcnc Image for RP4 via Raspberry Pi Imager (No settings aplied)
Chance keyboard layout to german
sudo apt-get update
sudo apt-get install network-manager*
Change the ethernet IP Adress to 10.10.10.1
Start PnCConf Wizard
Select 7i76s
Do the first couple of pages until the page for the X-Motor comes up. (nothing special there)
Input a Value into the stepper Scale
Test the Stepper= it works.
Then the following error occurs.
 
I can´t read anything into the error message

Since than i tried:
My 7i76e: Same error
A Intel Nuc from my Mill: No Error, works just fine
Reinstall Linuxcnc: No change
Chance Raspberry Pi: No change
Searched the forum: Didn´t find my specific problem

And now I hope, you can help me with my error

Can you run Plasmac offline was created by ashesman

Can you run Plasmac offline

Category: Plasmac

Is it possible to open Plasmac without Ethernet (Mesa 7i76e) connected?  I would like to be able to open Plasmac without being down in the shed with the machine.

It just crashes with a big messy warning that somewhere in there says 'network unreachable'.  Actually that is a gripe for me!  If my machine is not powered up rather than just a nice message 'cannot communicate', it just dumps a big mess on the screen that you have to scroll through too see what is going on.  Seems like a pretty common error that could justify a nice descriptive warning.  Or even wait for the machine to bee turned on, then carry on.  Just saying...

Raspberry Pi 4 performance plus 7i76E

Category: General LinuxCNC Questions

I'm new to LinuxCNC I've installed the canned 2.9.1 on an RPi 4 8GB and got it to ping the 7i76E.  Then I ran the Latensy Test page and I've attached a screen shot of the page after running for about 20 minutes with no additional load.  According to pages I've seen as far as latensy test is concern the numbers that RPi 4 latensy test show is not a good candidate for any serious stepping and micro-stepping.  Since I'm pairing the RPi 4 with a hardware step generator like the 7i76E, should I just ignore the latensy test?
