Yes, disabling that line makes everything work except for the PWM spindle.

Which parallel port breakout?

Can you post your hal/ini files?
 

To echo what rodw said:

Create a simple configuration with pncconf or MesaCT

Test this configuration by launching it from the command line

if there are issues you cannot resolve, post your error messages,  hal/ini files here

XY2-100 needs at minimum 3 differential outputs
(X data Y Data and clock) so you would likely need some
kind of daughter-card like a Mesa ENC422 that converts
single ended TTL level signals to differential signals.
in conjunction with the 7I97Ts parallel expansion port

(The converter is really just one chip (26LS31 equivalent on a small PCB)


 

Whats does the command:

ip a

report?

What happens if you:

ping 10.10.10.10

?

 

What was your user name here?
With the current one you have only this post.

Yes, the account is easy, but posts will take quite some time.

I have a Chinese parallel port board and I can't get the Y1 axis to be a slave to the Y2 axis for portigo on a plasma CNC machine. I'll pay for the help.

Thanks for the link. I had already looked through the thread and stopped at mesa 7i96.

However, I didn't see anything about optical correction. Is it possible to calibrate the laser with LinuxCNC, or do you have to use the manufacturer's software? 

Hi.
After 2 years I went to my home made hobbystic cnc to realize a project.
When used last time, the machine worked perfectly.
But today, starting LinuxCNC, I got a message error then LinuxCNC quit.

Here you can find the message (only the Print File Information section):

As I can see, the problem should be the Mesa board MAC address.
I didn't make any change (configuration, setup or else) last time I used the system (2 years ago), so I don't understand what happens.
Honestly, I made a first try with ChatGPT (I know, not the best idea but at the moment maybe.... - moreover it looks to me AS - Artificial Stupidity - more than AI - Intelligence....), but its suggestions were totally useless (some changes to ini and hal files), so I resumed my original files (attached).

Currently, LinuxCNC keep quitting; LinuxCNC correctly connects to the MESA Board.

My OS is LinuxCNC 2.7.14 + MESA 7i76e (Hybrid stepper drivers)

Can anyone help me to fix it?

Thanks

Andrea

These guys got it working with mesa and it seems  the pktuart so your 7i97 should do it..

ChatGPT is not particularly useful with Linuxcnc. I worry when I ask AI a question and it quotes into I wrote on this forum back to me.
now you have communication to the Mesa card, I would create a new config with pncconf and see how it goes. If it fails, share your hal and ini file and somebody will help. Also some rules.
1. Stick to the default axis user interface until you get a working  machine
2. Always start linuxcnc from the command line. That way you will see any error messages. Usually messages are fairly clear and refer to the file and line number 

I think the main difference with Linuxcnc is linuxcnc is a blank canvas where other systems have specific wiring terminals for specific purposes. That means you have a bit more work to do  as you have to define a bit more of your machine here. eg for coolant, you need to select a random pin on the 7i96s and then connect it to the appropriate internal signal. Also note if you have not defined your spindle, you won't see coolant/mist controls in axis. 

Proceed something like:
Get x,y,x morion working
Set up home/limit switches. If you did not have these, take the time to wire in a shared home/limit switch an all axes. It is much easier
Get estop working.
Work on your spindle. pin spindle.0.on needs to connect to the 7i96s pin you chose for the spindle on signal (spindle relay)
Set up your 0-10 volt speed control and scale it correctly
Get your encoder working (or do it later so you have something you can use)
Then set up coolant and mist. Test these with MDI commands M7,M8,M9
OIler then follows. I have not done anything with it but the pins are here
linuxcnc.org/docs/html/man/man1/halui.1.html#Lube

Main thing is to share console output and hal and in files here as you work through this so we can help

 

Hello everyone,

I am currently considering building a metal fused bed printer.

I currently have a 500W fiber laser with a wavelength of 1064nm.

I am looking for a galvo head for printing.

I would like a printing range of 300x300, so I am considering a laser beam expander to output 18–22 mm and an SL-1064-300-420 type F-Theta lens.

As far as I understand, the ideal solution for the head would be to find one with an xy2-100 protocol to use xy2mod.
And I am aware that I need to find a computer with very low latency.
I have a Mesa 7i97t, but I assume that it is not compatible because the protocol expects a PWM. What is the best card for galvo heads?

One last thing, is it possible to calibrate the galvo head? If so, how?
 

I think you have it correctly stated and just went to check precisely on the machine, but Linuxcnc won't start due to some mesa hardware issue. The lights are on, but looks like I have a day of diagnostics ahead.

Since the mill is a knee mill, the distance between the z quill and the table is not fixed so I don't think your system would work for me, if I am following your method correctly.

(Your English appears excellent to me)
