QCAD Bugtracker

ich habe ein Linien Gitter in QCAD erstellt und dann mit CAM Export eine NC Datei erstellt.
Im CAM Simulator sieht man dass der GCODE Postprozessor nicht den kürzesten Weg verwendet.
Anbei folgende Dateien :
CAM_TEST_LINIEN.dxf, CAM_TEST_LINIEN.nc, CAM_TEST_LINIEN.log und eine Bilddatei CAM_TEST_LINIEN.png hier kann man sehen wie die Eistellungen für die GCODE Erstellung sind.

Hallo Andrew

If CAM layer invisible do not 3D Simulate and do not write G-code.

Points are not being exported.

After regenerate selected toolpath OR regenerate all toolpath.

The result of the output is every time different.

When pushed for example 2 or 3 times this button.

See pictures

Trying the EleksMaker EL01 Laser router I noticed some bugs in creating pathways, rapids, tolerance and homing.

See the attached pdf

Hi Andrew,

Kubuntu, QCAD/CAM 3.21.3

Font Standard. Selected as ‘single line’ font for engraving with mill or laser.

While CAM Exporting as G-code Laser (Offset) MM, or as Linux CNC, Exporting gets trapped in a loop.

In Font Standard the glyph’s ? & $ @ s S Q and 2 contains unwanted Z-movements. It seems these glyphs entities are not alligned properly; endpoint last line does not meet startpoint next line; why else the Z-movements?

Could this misallignment also traps Exporting?

This option seems to only work with the script debugger enabled.
See:
http://www.qcad.org/rsforum/viewtopic.php?f=33&t=3091

Ij window CAM Configuration output unit appears as inch instead of mm. All parameters are in option
when create a nc file,units are in inches not in mm. unsuable and not possible to change

Under Linux the quantity is not correctly interpreted.

Case:
Nesting quantity all test: 3

Nesting block2 = works
Nesting block1 = fails (placed outside sheet),
Nesting both blocks = fails (placed partly outside sheet),

Within the nesting preparation:
A left mouse click to add a sheet will always be confirmed with “Sheet added”, regardless of a proper selection or where the left click is done in Model_Space.

Description for the CAM Nesting alignment:

Quote:
Alignment: Parts are arranged with the chosen alignment in mind. An alignment of “Left - Bottom” means that parts are shuffled to the left (primary alignment) and towards the bottom (secondary alignment).
Quote end

I tested a few scenarios. e.g
a Top Left, Align → leads to a top right alignment,
a Top left, Hull → leads to a Bottom Left alignment,
etc.

Hallo Andrew,

Found a bug in the drill toolpath generator.

The option “Cut inner paths before outer paths” is ignored, causing trouble when outer paths are cut first.

Attached is a link to the script files and gcode examples.

When I create a simple drawing, I cannot export the gcode until I restart qcad.

general steps to reproduce the issue:
1. open a new drawing
2. Add a letter “D” near the origin in Arial font, about 7mm tall.
3. explode it
4. save the drawing
5. Fill in in the “cam configuration” 6. Select the drawing and generate the tool paths.
7. Hit the “export button” or the menu item.
8. Observe that you see the “camexport” command appears in the command section, but there is no file generated for the gcode.

If you restart qcad, then the gcode will export as expected. Also, it appears to work for more complicated drawings. I had the same issue, when I tried to generate the same thing, but using the string “November 2019” at 5mm height. I am using up to date MX Linux with kernel version 4.19.0. I also observed this behavior under Windows 10 professional.

1. Load drawing
2. Create new drawing
3. Add toolpath / tool
4. CAM > CAM Export

Fails to identify current config (post processor).

If I want to draw circle with poin and raduis and write to radus window formula 4^2, Qcad calculates 4+2 not 4².

1. Click line tools button
2. Click button to draw lines with 2 points
3. Draw line
4. Right click
5. Click back button in CAD tool bar
6. Click Circle tools button

Circle tools not shown

CAD Tool Bar: Back button should go back one menu. Possibly use two buttons, one to go back to the previous tool bar, one to go back to the main tool bar.

CAD font styles not saved (except standard)

Hi Andrew,

Cabinet projections are usually drawn at 45 or 30 degrees, having drawn up many furniture configurations over the years, would it be possible to add options for 45 and 30 degrees at all?

C++ plugin interface to add functionality from existing C / C++ libraries to QCAD.

With multiple files open 4 of the 5 buttons of the Layer List Widget are acting on an other file that is open instead of acting on the file in focus.
in this condition only Add Layer YA acts on the file in focus.

Not easy to reproduce.
Encountered it more frequent
after copy with ref and pasting.
with more then 2 files open.
with similar drawing file names.
Did reproduce after several hopping between files.
Usually acts on the first open file but this can be different as in the example.

workarround none; save all; close all; close Qcad; reopen and redo.

Insert Block:

If I use the “Flip Block” option (Horizontal and/or Vertical) the Buttons doesn’t remains Highlighted. It should remain Highlighted ...

As came up towards the end of  FS#892 .

What happens is a change in src/3rdparty/dxflib/src/dl_dxf.cpp does trigger a rebuild of release/libdxflib.a, but this does not, in turn, trigger a re-link of plugins/libqcaddxf.so, a (the?) consumer of libdxflib.a.

This causes partial rebuilds to be broken (I think I got puzzled by this earlier too).

How to reproduce: on a fully built tree, `touch src/3rdparty/dxflib/src/dl_dxf.cpp’ then `make’. Nothing but libdxflib.a gets rebuilt.

Seems to have been introduced in 854baacb, it seems.

Just installed (31 jan 2015) on Win 7 64 bit. Two bugs are immediately apparent...

 bug 1 : Network drives are not listed in the file open or import dialogs - no way to access files stored on networked drives. (This is not a windows configuration error- all my other apps work perfevtly ok.)

 bug 2 : After about 5 minutes of initial exploration immediately after installation a window pops up... Trial Expired: The trial add-on CAM is no longer active (restart required).

Note: I do have neither of these problems on Windows XP (32 bit) which I installed yesterday

Spotted a bug with Polyline > Offset (OQ)

On the attached file (png image, link : http://nikel.ovh/~tukuyomi/oq_bug.png ), the white entity is a polyline (1 line, 1 arc, 1 line).
Using Polyline > Offset (OQ) with a big value (1100 in my case), I expect to get the green polyline.
What I have is the red one (also CPU is maxed for some seconds every time I move the mouse.)

Hallo Andrew

Confronted with a bug in font Standard glyph ”s” (small S),
and a solution.

If in the file’s name I’ve “/” (for ex. 2012/02/10) QCAD substite with “:” (2012:02:10). Regard the file’s name in the tab of QCAD.

Windows 8.1

Layers lost when using Isometric Projection tool

Test case

1.Set up layers.
2.Draw shape (I used a square).
3. Select shape and use Isometric tool (PJ).
5. Layers are lost as soon as reference point is selected.

please see screenshots:

Please see topic:
http://www.qcad.org/rsforum/viewtopic.php?f=31&t=2445

Windows 7-64

Please see attached a simple test to demonstrate the problem.

Breakout tool

1. When selecting the top half of the circle - the top half of the circle ‘breaks’ out as expected.
2. When selecting the bottom half of the circle - the whole circle disappears!

Autotrim tool

1. When selecting the top half of the circle - the trim seems to work.

2. When selecting the bottom half of the circle - no trim happens at all!

Break out segments of ellipses

See fs731.dxf

See:
http://www.qcad.org/rsforum/viewtopic.php?f=32&t=3005

3.4.7 trial as well as community Git 9d3979

• Draw a circle
• B2
• Make sure “Remove segment” is ticked
• Select circle, then select two points to break out in between

Expected:

• Segment gets removed (not really, but read on)

Actual:

• Segment does not get removed, but circle is indeed broken into two arcs

Same for an ellipse.

I can see that by selecting two points on a closed circular shape it’s nigh impossible to tell which segment the user actually wants to remove :)

The documentation doesn’t mention this corner case. For clarity, a note detailing this effect a bit should be added to the docs.

On a slightly related note, I do not see why the feature couldn’t work on Polyline objects as well (with the same corner case restriction if it’s a closed polyline).

Very useful feature btw, thanks for it.

break out for top segment of arc broken

Make sure that block references of hidden blocks cannot be selected.

Loading any larger dxf file takes very long because of this line:
istr.imbue(std::locale(”C”));

The call to std::locale is very slow. File-loading can be speed up by approximately factor 5 times on my system when replacing it. I just removed that line and instead added the following in DL_Dxf::in so it is changed only once per file:

std::locale oldLocale = std::locale::global(std::locale(”C”)); // use dot in numbers
while (readDxfGroups(fp, creationInterface)) {}
std::locale::global(oldLocale);

The numbers in the book don’t match with the bookmarks numbers in the PDF as shown in Acrobat Reader.

Post all kind of layout issues for the book “CAD Instruction” here, e.g. overlapping text.

Using the bold function (button) in the text editor causes transaction fail on new text entries. Emboldening selected text on existing text shows bold in the editor but this does not carry through to drawing or print preview views.
