LinuxCNC installation + 7I96S

My PC uses a Realtek RTL8111/8168/8411 network card, integrated into the Gigabyte motherboard.

Does this network card model cause problems with Mesa?

THC qtplasmac 2.9 is moving UP when it should be moving DOWN

Category: General LinuxCNC Questions

To add to what Tommy said ...

From: linuxcnc.org/docs/devel/html/plasma/qtpl...ml#plasma:z-settings

[AXIS_Z] MIN_LIMIT should be just below top of the slats with allowances for float_switch_travel and over travel tolerance. For example, if the user’s float switch takes 4 mm (0.157") to activate then set the Z minimum to 5 mm (0.2") plus an allowance for overrun (either calculated using the equation below or allow 5 mm (0.2") below the lowest slat).

[AXIS_Z] MAX_LIMIT should be the highest the user wants the Z axis to travel (it must not be lower than Z HOME_OFFSET).

[AXIS_Z] HOME should be set to be approximately 5 mm-10 mm (0.2"-0.4") below the maximum limit.


There's a nice diagram there too.

Is there a new Linuxcnc release in the wings ?

Category: General LinuxCNC Questions

But Andy does have a good point, doesn't he? It would be much better if this was fixed in the official linuxcnc distribution.
Perhaps you can open an issue at linuxcnc github and see it you can get your fixes incorporated?

You mean propellers?
Pretty damn well, none have disintegrated so far and mostly the smaller ones stay intact when bumping into something while spinning, it takes a bit of effort to break them, and that is mostly due to printing direction.
Also i do not use PLA, ABS, HIPS, PETG, and lately PA6 Nylon.
The main issue are sanding them properly will improve efficiency a lot, and balancing them is a must sometimes.
Give it a try, you will be surprised how good they can be, just keep layer line longitudinally.

It could be done. It's probably how I would do it if I had to control an injection moulding machine, but only because I already know how to use LinuxCNC.
(when your only tool is a hammer....)

Getting temperature into LinuxCNC HAL is not the easiest thing. One option is:

First such machine i fixed was back in 1990 !!!
They are complicated machines, but all are made from simple parts, so look at it as separate parts, makes it much easier.
The main hurdle with retrofitting such machines is the logic and interlocks, writing down whatever you already know will help a lot during programing.

but if there's no new tutorials out there to guide newbs, then i might as well not waste my time and just install windows.


Makes me wonder why we bother maintaining about 1500 pages of written documentation:

Yes, that's a solution. I'll think about it, if I start modifying the code (I'm not very good at programming) or if I find a solution to add additional control switches (from my window, this solution seems the easiest to me)

Probe Basic is written in Python, you could modify it.

Try a different layout with a 2-element V-box with a 2-element H-box in the top box.

I think that your meter is being constrained to be same width as "Licht" as it is in the same column.

I've already looked through the list, but I didn't find anything conclusive.
It was just in case there was something I'd missed or done wrong.
So your comment supports my analysis, but not really the right one for me. I'll have to find another solution...

Hello,
i created a small ui with glade with two leds, two buttons and a Hal_Meter. How can i enlarge the Hal_Meter? Attached is a screenshot of my main window.

Thatś it. Thanks

My custum_postgui.hat is now correct
#[Spindel]
net spindle-vel-cmd-rpm => gladevcp.Spindel1

I guess i really have some problems with reading signals in the machine.hal. I thought in my case "spindle.0.speed-out" give me directly my float value. Have to write a small manual for me.
