Version aktualisieren + diverse Fehlermeldungen

Category: QtPyVCP

Yes, I think so.
I uninstalled and reinstalled like pint 4. and 5. in this Tutorial:
kcjengr.github.io/probe_basic/stable_develop_branch_change.html
Got no errors during deinstall and reinstall.
But nothing changed on these errors.
The sim opens wthout any problems and seems to work without any problems.

Becouse of an networkproblem, I checked my Firewall and found nothing at the logs. 
The last error was becouse of the blocked Port TCP 11371 whos needed for the Public_Key.

Chris. appologies for bring this up again.
I have notices a pin named 'qtversaprobe.enable'
what is it? and where does it come from?
it is an output of something......

Hi Arciera,

The motdot.so logic is that it sends just one gcode line, or it sends a buch of lines.

If it sends just one line,
then it waits for this line to get ready. After that it sends 100+ gcode lines in portions. (most of time 2000 as the buffer size.)
So it's not that we get complete gcode at once. Therefore if we get only one line, we dont trim this one.

You can test this by turning of the program velocity to zero before pressing the run button.
If program speed is zero it won't send the bunch of gcode lines.
If you then turn on the program with speed, it will send more lines at once.

In the logic of the code at the moment, we don't trim the first segment's front. And last segment's back.

Maybe you have an idea what should be the route.

Note:
In the new planner, we are able to buffer including the first segment.

To me it seems that if we could pass on information about how much the segments of an intersection have been trimmed to the clothoid fitting function we could adjust the parameters of the clothoid such that we fit the larges possible fillet to that intersection. If you see a way to derive this information from the trimmed segments then I'm all for doing it your way
We know exactly what we trimmed and how much every segment is trimmed on bot's side's in mm.
The clothoids fit's given a start & end point. The clothoids use a start & endangle, and a curvature start & end.
That are in total 4 double values and 2 points.

So to change a clothoid, the only thing you can do is change the start & end point. Curvature's and Theta's are fixed.

If you mean something else, like max deviation from the clothoid to the path, this can be calculated also.

Installing qt is a terminal command.
sudo apt install qtcreator
sudo apt install qtbase5-dev qt5-qmake qtbase5-dev-tools

Are you using qt for it as viewer and editor? This should be the nice as you can load the cmakelists directly in qt.


No, I'm using Eclipse, mostly because I remember the headaches I had trying to get Qt installed and setup correctly.


I played around a bit and moved the test for segment length vs trim_distance to 'trimCurves' which seems to work (although sometimes there is a problem with the first corner being falsely excluded apparently depending on where the tool is located at startup):

Is there a particular reason for not handling one fillet after the other?
In a other function, we start with a list of segments. (gcode input) .
They then already have a flag if they may be trimmed front & back.
It this point the empty fillet segments are inserted inbetween. This is a vector insert operation.


Not sure I understand what you are saying. To me it seems that if we could pass on information about how much the segments of an intersection have been trimmed to the clothoid fitting function we could adjust the parameters of the clothoid such that we fit the larges possible fillet to that intersection.

How to use QStyleSheet with actionButtons? was created by bladekel

How to use QStyleSheet with actionButtons?

Category: Qtvcp

I'm trying to create custom qui with QtDesigner.
I have an interesting problem with actionButton.
I added an actionButton to my MainWidget,and set Action > Machine Control > Home
So far everything worked as it should.. I pressed the button and it started to homing...
After that I wanted to add color change to my Home button with sytlesheet
ActionButton[isHomed=false]{
background-color: rgb(61, 56, 70);
}
ActionButton[isHomed=true]{
background-color: rgb(51, 209, 122);
}



I tried both isHomed,isAllHomed,is_homed_status and is_joint_homed_status...

Also I tried for estop button, machine on button... All the same...
The button action worked but the stylesheet not worked.

My QtDesigner version is 5.15.8, linuxcnc 2.9.3, and working on raspberry pi5 ....

And here is the xml code part of actionButton...

7i95T spindle control via Modbus RS485 and SPINX1A

Category: Driver Boards

The SPINX1A has a 2 pole ~ 100 Hz RC filter to average the PWM signal.

Too low a PWM frequency will let noticeable ripple through the filter.
Too high a PWM frequency will result in poor linearity, (as the switcing
time of the OPTO becomes a significant part of the cycle time)

For the SPINX1A, 20 KHz is about the optimum compromise between ripple and linearity.

Example of HAL configuration for plasma torch height control with THCAD2 7i96s

Category: HAL Examples

3rd The big problem is that LinuxCNC does not understand that only a frequency signal from 100 to 1000Kz determines the feedback of the Z axis position.

I think this was already discussed  in another thread. I think the best way to do this is
step by step

The first step is to scale the encoder velocity into the desired units (mm?)
This can be done with the encoder scale parameter, but it's likely you will need
an offset, in which case you can feed the encoder velocity through the offset
component. When this is all done you should have a direct scaled position signal.

To calculate the scaling you will need to move the Z axis to 0 position, read the
encoder velocity, then move Z a known distance (preferably near full range of motion)
and then read the encoder velocity again,


The second step is to feed this signal into the feedback input of a PID component.
this PID component will force the Z axis to follow the Z axis position command from
LinuxCNC.

If you setup a normal analog + encoder feedback LinuxCNC configuration
with pncconf for 7I77 hardware, all of setup/connections/components will have been created
for you and the main change that needs to be done is substitution of the scaled/offset
encoder velocity for the encoder position that pncconf setup.
