Thank you for those lines, I'm now receiving signals!

Could you suggest the appropriate numbers for type, frequency, and scale?

I attempted the following settings, but I’m getting a +10V output at the spindle, even at M3 S9000. This should ideally be half of that value.

setp hm2_7i95.0.pwmgen.00.output-type 2
setp hm2_7i95.0.pwmgen.pwm_frequency 2000
setp hm2_7i95.0.pwmgen.00.scale 0

In terminal "qtvcp copy", check "qtdragon", name "qtdragon_custom" for your case, then ask you to create folders, agree, ask for copy, agree also. Now in your home folder will be qtvcp/screen/qtdragon_custom. You can modify it as you wish, and the original files in the system folder will be unchanged for comparison.

Hi,

I am trying to make a custom qtdragon_handler.py file, which I will call qtdragon_handler_custom.py, but it seems I do not have any permissions to modify whatever in the qtdragon folder (only root permision).  Since I am quite new with Linuxcnc (and Linux in general), I am asking the community for some help.  Thanks!

Be wary of those devices, they could just be a USB to parallel port. I bought a similar device thinking it would be a proper hardware serial port, but what it actually was a a USB to serial port.
Getting the right laptop to work can be a bit of a hit & miss exercise. Tho it's not something that I would recommend for a parallel port setup. Mesa maybe.

You may find you will you need an RTAI kernel.
Tuning for a machine that has to run a base and servo thread is a bit harder than one that just requires a servo thread.

Ah, yes, the kernel, too. But that's good news. Thanks a lot for weighing in. 

I think it will either be this route or, dare I say it, a laptop;). But then it will likely be with a Mesa card. That said, there are some Lenovo laptops with a slot for those PCIe cards so parallel port may still be an option:
 

This is a random error. I have many other files that are not working. At the moment I am solving the problem by moving them to the root of the machine configuration folder.

Samba was the next thing I was going to address.
Simple sharing by using the file manager no root intervention required .
Tho if you need file sharing from Linux to Linux NFS is a far far better solution.

I couldn't get wpa_supplicant to work at my site. Being the lazy ass I am I found it easier to just edit the interfaces file.
Then working out I was even more lazier, and I like to enable and disable wifi on the fly, I installed network-manager-gnome.
To be honest I'm thinking that building an update image for the RPi 5 with network-manager might be worth it. If users want to use the gpio driver they'll have to disable it
Why didn't someone read the info with the download ?
1: people are lazy
2: people don't pay attention they just want the instant reward
3: they just download from a link.

I put up a link to the Debian way of setting up networking, but I don't think people read this thread or read a thread from the beginning.

Hi All, 
While I just received some lovely Mesa boards for my mill project which will run on an older, seconhand Lenovo Tiny with a likewise secondhand touchscreen, I am thinking ahead here for a cheaper way to run Lcnc on a small lathe. 

I am based in Asia and can tap into the Chinese used market easier, faster and way cheaper than I can source new or used from US/Eu and I also do need to do the next project a bit cheaper. 

I just realized that quite a lot of the 2017 onwards Tinys have full PCIe slots which via a cheap riser should be able to accept regular PCIe expansions boards like parallel port ones.
So, for the small lathe project which wont need many IOs and just 2 axis, I was thinking of going old school with parallel port and one of those cheap 5-axis parallel boards from China. Granted, a Tiny with PCIe will be slightly more expensive than my older one without PCIe but not by much. And the riser adapter and extensions can be had for just a few bucks, too. At the end of the day, maybe I wont actually save more than 100-150 bucks or so but I am willing to give it a go. 

Now, the simple/stupid question: Parallel port is still cool for Lcnc, right? I wont lose out on any software functionality other than having a much less swank, feature rich and well built board like a Mesa and having to use a different configuration tool? But once setup, I can expect it to run the same as on a Mesa?

Here's that 5 axis Par board I mentioned (less than USD 3):
 

Oh, before you say RPI 5 can do Par Port too and there's even a hat to interface it to this exact 5 axis board, I think I'd prefer to stick to a Lenovo Tiny. The latter wouldn't even cost much more and I could keep a copy of Windows on it for when/if I need to tune servos and such. 
 

@rodw, I haven't checked recently, but the iso had an old qtpyvcp source listed that causes some issues and requires removed to resolve. We updated the instructions to use the lockdown deb on the forum page as it doesn't have the outdated source.

People who follow random methods to install Linuxcnc are bound to  end up with issues sooner or later as things change
Install using the image on the downloads page and install probe basic etc from repositories
This will mean you get better support as people like Lcvette will be dealing with a known environment.
 

Why didn't you follow the instructions on the Downloads page to setup wireless networking and simply type:
sudo menu-config ?

Re a fixed IP wired connection for Mesa Ethernet card, follow the directions in the man page for hm2_eth (type man hm2_eth) or follow this link.
linuxcnc.org/docs/stable/html/man/man9/hm2_eth.9.html
If you are using a wired connection for internet, there should be nothing to set up as it will get an IP address from your router automatically using DHCP. 

This may be easier to chat in real time
