>Whether it is your present depends on a lot of factors. Usually money

OK. In my case, Pulse/Dir has been working reasonably well for my needs so far, and most importantly I was able to get it working with very limited (aka known) knowledge to start with.

However, since I chose the most simple/cheapest way using parport and basic Bob, I have no room to implement things that would be really useful, such as 4th axis, tool gauge, feedback to LinuxCNC, etc... Any solution that would remove these limitations would require money, so I might as well go for some sort of industry standard, or at least a solution that is not strictly dependent on a single vendor.

This discussion conforts me in the idea that EtherCAT seems a logical choice in this respect, so thank you all for sharing your knowledge and experience

Yeah I figured that cos building an image with the 6.12.y branch fails when creating the final image. 6.1.y with the 6.1.69 kernel commit seems to build ok, image is created with Linuxcnc binaries and when patch has spi on at first boot. This was just seen by mounting the image and having a quick browse through the filesystem. Too effing late to test.

Another thing of interest there are still patches.
Directory listing of the patches that are for 6.12.8 none for 6.12.9 as you can see (6.12.8) has patches for sysfs entry and one to for enable arm rt.

So this looks like a very confusing kettle of fish.

I don't what your doing different but using the rpi-linux source from their github repo, I cloned the whole repo, I'm getting this, unpatched sources.
Just out of interest are you working from the same kernel source as myself.

iv not really had issue using UVW on my lathe with two turrets
only part i miss is running them together todo parts, as 2nd has to sit around while other is machining then swop over.. but thats a limit of single path controlls.

as for spindle control
i think the issue with sub spindle, or infact more than 1 spindle is there is no standard when it comes to Mcodes for direction or sync codes also

the only part that remains normal on machiens i find is S1, S2 etc , 1 is always main, 2 is sub and 3,4 etc tend to be turret power tooling etc.

one of my machiens for spindle sync has this code
G114.1 H1 D-2 R0
M77 (wait & check for sync to complete)

G114.1 spindle sync active,
H define which is the master spindle
D which spindle is doing the following
R phase offset from spindle axis zero

M77
follow by M77 makes the machine wait for sync to finish before processing more code, if no R is used can skip M77

this can sync to a already running spindle or both can syn from M5 and start together etc.. ovbisly can sync power tooling to a spindle, spindle to power tooling etc.. so gear hobbing , polygon is possible.

there is also a torque code you can issue to limit torque of spindles on pickup or check the part did part off fully before retract etc.

G114.2-Polygon machining command. There are many unique ways to use
polygon machining. Not just for hex or square shapes. Side slots,
Phillips screw driver shapes and whatever else can benefit from the
live tool synchronized with the part while cutting. Use G113 to
cancel.
G114.2 H3 D1 E3 L6 (R15.)
H3 = Master spindle or S3(gang live tool) S4 U121B option
D1= Slave spindle. Could be 1,-1, 2, -1 - is for direction.
E3 = Rotation rate. Number of teeth of the cutter.
L6= Number of flats to be cut on the part.
R15. = Phase shifting amount in degrees.(only on 1:1 ratio
spindles)
G114.3-(option) Gear hobbing command. With a special holder this command
will
time the cutter(S3) and spindle(S1C1) to constantly hold position
so all we do is feed across the part as if we were turning and a
gear shape is cut. A "C" axis is also needed! Use G113 to cancel.
G114.3 H3 D-9 E1 L18 (P0) (Q1.)
H3 = Master spindle or S3(gang live tool)
D-9= Slave spindle or 9= Caxis -9 = reverse
E1 = Rotation rate. Always set to one. Not sure exactly why!
L18= Number of gear teeth to be on the part.
P0 = Helix angle -89.000 to 89.000 for helical gears. Leave off
or set to P0 for spur(straight) gears.

just be aware that later hardware may need a later OS to get driver support.

Maybe it helps if you post your macro file.

Sorry, I have not had a chance to look at this over the weekend.

As far as I know the SpeedControl cannot be styled by CSS.

You have to change either the glade file or do that in a user command file (linuxcnc.org/docs/stable/html/gui/gmocca...l#_user_command_file)
with that content for example:

In the glade file only the button sizes can be enlarged. But only those ones that are not being generated.
The icon sizes can only be enlarged in the code. So the easiest is to do that within a user command file. Simply increase the icon sizes in the file attached. But keep in mind that this works only from the start until you change the icon theme in the settings.

AND please write in English. You can't expect that the people you want to get help from are willing to do the extra work and copy your text into a translator.
Also this could be treated as spam and be simply deleted. Other languages are welcome in www.forum.linuxcnc.org/37-international-linuxcnc-users

I don't know what you do wrong, but this is without any patch or modification:
 

It seems that this user also didn't need additional patches: forum.linuxcnc.org/38-general-linuxcnc-q...6-12?start=10#318472

I didn't find a way to reduce the 50px area around the GtK Paned because it's hard coded in the Gtk sources.
So I removed the Gtk Paned again. This is now in the 2.9 branch and so master as well.

"What would the open function do?"

If you use flexqss to make a qss file then close it, your done. You can't edit it after the fact without some File->open type function. There's an awful lot of different selections to make having to make them in 1 sitting.

"Can you elaborate on apply the background colors?"
How do you change the background color without using a theme in the ini? If you specify a qss, the theme doesn't work.....or at least that's what I'm seeing. From my setup, it's either use a flex theme or the background is white.....and my qt theme is dark on my Debian VM. Designer preview shows my ui as dark, launching LinuxCNC with a qss specified it is white....so maybe I'm missing something.

FYI: it's now in 2.9 and so master
