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.

 

Ah, I hadn't thought about the "hidden" USB being a risk at all. 

Tommy Light has a good little thread on Lenovo laptops that he has gotten to work great on production machines so if I go down this path, I would try to get one of the ones he has had luck with. But yes, he does run them on Mesa Ethernet cards. 

Thanks again, let's see what I'll end up with. This is research as of now though I do think I'll pick up the lathe within a few weeks. 

Thanks a lot, this is now working well.

I think it's good to have an information system that notifies also about new features that are disabled by default (for compatibility reasons).

I implemented such, based on Acieras snippet.
It is able to hide the messages you have read but displays new ones id there will be any in the future.

You can try it out using this branch: github.com/hansu/linuxcnc/tree/gmoccapy-info-message

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!
