[Emc-users] Controlling a model airplane servo with LinuxCNC

I figured this would be easy and I was right. The HAL and INI files are produced by Stepconf with no edits. I connect a cheap $5 hobby servo motor to the parallel port pin #16 with no extra hardware, just a wire. I also run 5 volts DC to the motor.The default signal generated by pwmgen and

[Emc-users] Maths (wow)

When I was working with a Fanuc robot, and if in a tight space, I would often get a 'singularity' error. Two axes are too parallel to each other. Then you have to fiddle with the program to get out of the paradox. Thing is, in all of my life of picking up things, my arm has never frozen from a

Excellent catch: *Excellent concentration when watching more than an hour of a presentation * Excellent identification of excellent code * Excellent graphics in the presentation, which shows off the super flexibility and power of the code. is it possible you have a favorite CAD

Thanks all for testing the video link. I found out that the only universal way to post video is to post to Youtube. So much of if you can see a video or not depends on the email reader and your OS. But Youtube seems to generally work https://youtu.be/CiKr-slum1Y On Sat, Jun 27, 2020 at

[Emc-users] gcode stuck, won't proceed

Greetings all; When I got to the machine this morning and restarted LinuxCNC, the jog dials both worked. And they still are. But turning a hub for a 3d printed sprocket out of a block of alu has turned into a problem. Here is the gcode: % ( adjustable turn routine ) G21 G7 (metric,

Re: [Emc-users] Freecad

Figure out where the old install place FreeCAD. Type "which freecad" and the you see the full path to the program. Then just deleter is using "rm". If you have some kind of desktop shortcut to the old freecad you just deleted then edit them to point to the appimage. On Sat, Jun 27, 2020 at

I thought I would post this for anyone that might step this way in future  Following discussions on freecad producing g-code, I've been experimenting. The workbench is where this all happens, but going to that location produced "libnglib.so: cannot open shared object file: No such file or

Funny.. I *JUST* found this issue.. sudo apt install netgen sudo ln -s /usr/lib/x86_64-linux-gnu/netgen/* /usr/lib/x86_64-linux-gnu/ Should get it to work.. however, I've had FreeCAD crash 3 times in the past 15 minutes trying to use the Path workbench. I'm going to try the appimage to see if
