30/10/2024 - Solving a problem when 3D printing using "one-at-a-time" with Cura (and FLSUN)
When 3D printint using "one-at-a-time" using Cura Print Sequence (printing full pieces in sequence) in a FLSUN 3D Printer, we have experienced a delay problem in the second and subsequent pieces.We have analyzed the problem and the cause is a gcode sequence inserted by Cura at the beginning of each piece, that forces the bed to cool and warm again.
This problem can be solved/avoided by manually editing the gcode of the printing (for example with the notepad), and deleting the following gcode-lines that Cura inserts before each piece (forcing the bed to cool):
• M140 S{material_bed_temperature}; set bed temperature, in our case, it was M140 S60
• M105
• M190 S{material_bed_temperature}; wait for bed temperature, in our case, it was M190 S60
• M104 S{material_print_temperature}; set extruder temperature, in our case, it was M104 S220
• M105
• M109 S{material_print_temperature}; wait for extruder temperature, in our case, it was M109 S220
The first time this code appears in the gcode is the correct one, but the other replicas appearing in the gcode (at the beginning of the second and subsequent pieces) should be replaced (these six gcode-lines) by:
• M105
Alternatively, this replacement can be made in Cura: Going to extensions, post processing, modify g-code. Add a script and select "search and replace".

Aunque pueda parecer sorprendente; es mucho m�s eficiente (energeticamente y mediambientalmente) disponer de una gran central el�ctica que funcione con gas y que los usuarios gasten energ�a el�ctrica en la calefacci�n que la alternativa de que cada usuario dom�stico tenga una caldera de gas en casa (entre otras cosas se genera much�simo m�s CO2).

roseus, by itself, uses the length of the current figure's colormap.
It works like the other colormaps: hot, hsv, parula, gray,...
The 'roseus' colormap is used in audacity for improved spectrum visualization.
Adjust the color limits of the spectrum image to mimic the audacity spectrum.
Usage examples:
>>c = roseus(15); % returns a 15x3 'roseus' colormap
>>c = roseus; % returns a Mx3 colormap, M is the length of the current figure's colormap or 64
>>colormap(roseus); % sets the 'roseus' colormap on the current figure (spectrogram example shown in the figure)

Defining the Consistent Velocity of Omnidirectional Mobile Platforms,
Machines 2024, 12, 397.This paper proposes the definition of the consistent velocity of omnidirectional mobile platforms. This velocity is an upper bound to the translational velocity of the mobile platform, which is defined as the minimum of the maximum translational velocities achievable in any angular orientation.
It depends on the mechanical configuration of the omni-wheels of the platform and on the maximum angular velocity allowed by the motors driving the omni-wheels.
It has been found that the consistent velocity does not depend on the relative orientation of the omni-wheels in the mobile platform.

1) Create an space for the table in word. 2) Go to Matlab and call this function. 3) Click over Word. 4) Wait until the whole matrix has been copied (do not change the focus from Word).
Function also avialable at Fileexchange.
>> matrix2WordEq(M);
This function copies the matlab matrix M into a Word equation (through the clipboard):
1) Create an empty equation in word. 2) Go to Matlab and call this function. 3) Click over the Word equation. 4) Wait until the whole matrix has been copied (do not change the focus from Word).
Function also avialable at Fileexchange.

SLAMICP Library: Accelerating Obstacle Detection in Mobile Robot Navigation via Outlier Monitoring following ICP Localization,
Sensors 2023, 23, 6089.This work proposes to speed up the obstacle detection process by directly monitoring outliers (discrepant points between the LIDAR scans and the full map) spotted after Iterative Closest Point (ICP) matching instead of spending time performing an isolated task to re-analyze the LIDAR scans to detect those discrepancies.
This paper presents the SLAMICP Library: a Free and Open Source library that we developped to implement ICP matching returning the outliers detected and other internal matching parameters during mobile robot navigation.
Point Cloud application example of the SLAMICP Library
Mobile robot following a planned trajectory: the blue dots depict the 2D map of the facility;
the dotted cyan points depict the planned trajectory and the green arrow the final position and orientation that must be achieved by the mobile robot;
the solid olive line depict the real trajectory followed by the mobile robot and the brown arrow depit ist current position and orientation;
the red points are the outliers detected after ICP matching that (in this case) reveal one side of an obstacle placed in the corridor.
