neeed help with additional pwm 6i25 and 7i76

Category: Basic Configuration

Omit the offending line and try again
from
setp hm2_5i25.0.pwmgen.00.pwm_frequency 1000
to
#setp hm2_5i25.0.pwmgen.00.pwm_frequency 1000
---
I have flashed the 6i25 with 5i25_7i76x2pld.bit
I am pretty sure that is for plasma systems, so the spindle encoder inputs are NOT A/B/Z, but are A0/A1/A2 for 1 to 3 of THCAD.
Anyone, do correct me if that is wrong.
Thank you.

Any experience with cnc-step machines?

Easy way:
-download the official ISO from the downloads page, burn it to USB, boot the PC from it
-test as much as you like, start the includes sim (simulated) configurations, they do everything without a machine attached
-get an old PC with a parallel port or get an add on parallel card
-get some cheap TB6600 drives and motors
-cobble something together so it moves, some short rails and belts should do just fine
-enjoy, you will learn more form doing this than reading for months
=
If you feel like it, get a used industrial machine, plenty of those where you live, preferably with dead controls, retrofit it with Mesa boards, make chips/art/decor/money
Can be found from 1-5K, another 700-1200 for Mesa, PC, cables, ferules, crimp tools, maybe power supplies and other stuff.
You end up with a magnificent machine.
And sorry but i have to say this: requires absolutely following advice from others here. This is where some fail miserably, luckily very rarely.

I see no reason for it as this is open source forum, while that is not open source.

PCI card recommendation was created by BX-CNC

PCI card recommendation

Category: General LinuxCNC Questions

Hi all,
I need a PCI card with parallel port for my first CNC setup. Now I find one on Amazon, the chip is Asix AX99100 chip.
Here is the link:
www.amazon.ca/StarTech-com-1-Port-Parall...1a&gad_source=1&th=1

Will this one work? Or do you guys have any recommendation? Thanks a lot.

lspci -v
sudo cat /proc/ioports | grep parport
ls /dev/parport*
these commands
 
user@linuxcnc:~$ sudo cat /proc/ioports | grep parport

Sorry, try again.
[sudo] password for user:
user@linuxcnc:~$ ls /dev/parport*
ls: cannot access '/dev/parport*': No such file or directory

This is what i get after enter the password, nothing happen

 

 

It seems you don't have a parallel port at all.

Are you using an old computer with onboard parallel port or a new computer with PCI card?
 


and I did try using the parallel port tester but i got this
user@linuxcnc:~$ halrun -I -f ptest.hal
Could not open command file 'ptest.hal'
halcmd:


 



You have to open the Terminal Emulator in the same folder where your parallel port tester files are. For this, right click somewhere inside the folder then "Open Terminal Here".

But with USB to parallel adapter it wouldn't work in anyway. Find a good parallel port PCI card and try again. Avoid any WCH chipsets.

@IHaveNoFish,

Thanks!

Today i started investegating something new.  experimental code

The question is, can we use a clothoid curve for motion, just like the scurve is a curve used for motion?
The idea came up a while ago. Scurve motion uses derivates, the clothoid also uses derivates.

Somehow i used the clothoid curve for the velocity profile.
The theta start of the clothoid curve is a vector, this can be transformed to acceleration start and visa versa.

1. The x axis of the clothoid is then time.
2.  The y axis of the clothoid is then velocity.

During the curve's velocity profile, we printed the acceleration values along the curve. What i didn't know is,
the acceleration profile is not a straight line as like the trapezium or scurve motion profile.

Here is a plot of acceleration stage, mention the acceleration line. It's curved. This involves less Jerk?

Retrofit: Maho MH400E to LinuxCNC

Category: Show Your Stuff

Got the Mesa 7i94T and 7i77 boards powered up today, and it’s great to finally see the pins show up in LinuxCNC.


 


Also managed to remove the tool holder that had been stuck in the spindle since I got the machine — definitely satisfying to get that out of the way.I’ll shorten the IDC25 ribbon once the board layout is finalized. For now, I’ve ordered breakout boards to avoid cutting cables too early: three for the Heidenhain DB15s, two for the Indramat DB9s, and two for the IDC40 ribbons.


The original Philips 432 hardware is completely gone. I briefly considered replacing the whole cabinet to avoid upgrading the mains fuse, but in the end I’m likely going for a proper electrical upgrade: increasing the main connection from 25A to 40A and switching from a B16 to a C25 breaker (still waiting on the electrician to confirm this setup).Once the wiring takes shape, I plan to capture everything neatly in EPLAN to avoid spaghetti later on. Slowly but surely, things are coming together.

Thanks, Mark. It's going slow but steady.
I can't forget you saying "and basically, that's it". Yeah, if only.

I'm trying to get this working. Ive read most of the other relevant threads and the documentation.
I have flashed the 6i25 with 5i25_7i76x2pld.bit
here is my hal and these are the only code i have that references pwm

I know I am a bit late to the party, but there's a NC Shop Floor Programmer postprocessor for LinuxCNC on the SFP wiki.

r1132100503382-eu1-3dswym.3dexperience.3...ftfpxcTGarZ6eplZQaew

Also, SFP includes ICAM Foundation for developing your own postprocessors.

Hope this helps someone in the future

Took me while to recognize that you had re-railed the thread again...
As for the control boxes: I have no idea, but I have little idea anyways. So as it stands, I expect to have answer like "well we had that one guy who nḿade it work with LinuxCNC, so that is why we claim it is compatible".
So as I am willing to go quite some way to spare me the pain of running a Windows computer with closed source running my CNC, I tend to get the mechanical parts form one supplier and gather information on which steppers, mesa cards and stuff I should get to have a working LinuxCNC in the end.
I am aware that will most likely end in a bigger amount of pain in the first run, but I am willing to risk that for the better end result.
I just wait for the answer of the cnc-stepper guys and continue from there.

Hi . on Debian 10 with ethercat , for refresh configuraztion the ethercat i was use command : sudo -S update-ethercat-config

Now stey use debian 12 with ethercat 1.6 installed with step-by step procedure, but the command  sudo -S update-ethercat-config
 return command not know.

When change the file etc/ethercat.conf how can refresh ethercat on debian 12 ?

Thanks

    I did the whole process to change the firmware of the stlink, it was successful, but it does not appear on my PC, the only difference is that I did not find the blue stlink so I did it in a green one, I used two green stlinks, would there be any difference? If so, how do I find the blue stlink, when I go to buy the cover and everything is the same
