Problem dxf files etc... / What is wrong with that DXF ? Any ideas ?

« on: August 07, 2019, 10:29:12 am »

At first - I believe it´s a QCAD problem and not a CB problem.

Nevertheless I would be thankful for any idea or a hint, so I can raise a complain at QCAD.

I´m creating DXF files using QCAD, to toolchain with CB works usually fine,
but occasionally (? yes, occasionally !) the file is written in a manner that CB imports nonsense !

See files Bullshit and No_Bullshit.
The content and layer structure is identical.
Bullshit was edited approx. 15 times. But suddenly :

Import into CB results in
- ignoring layer colors (everything is green)
- some layers are missing

Loading Bullshit into QCAD : everything´s correct
The only way to reduce the problem is : re-load into QCAD and do a "save as" and overwrite
or create a new file.

What also helps (not always) : Waiting at least 5 seconds after last change before saving the DXF,
wait at least 5 seconds before closing QCAD and wait at least 5 seconds before importing into CB.
VERY, VERY STRANGE !

I made a file-compare, there are slight differences, but I cannot figure out the problem.

Best regards

Problem dxf files etc... / Can´t change start point of polylines - drives me crazy !

« on: April 28, 2019, 13:19:51 pm »

Dear Jedies...

Ohhhhh - these bloody polylines ...

Am I doing something wrong ?
I select the polyline - then polyline - set new start point
I left-click at the new start point (yes I REALLY click at a point of the polyline).

But nothing happens. Creating a new MOP with that polyline I notice
the start point was not changed.

It is a closed polyline, not really complicated.

This problem I have usually, just in very seldom cases my new start point is accepted.

Joining the polyline is also not helpful - sometimes CB changes the startpoint when joining.

Any advices ?

Best regards

Scripts and Plugin Help / How to create a MOP inserting G-Code by script (Python) ?

« on: March 16, 2019, 11:03:30 am »

Dear CAMBAM-Jedis,

(maybe I´m not asking the correct question or I´m not using the correct terms.)

I try to make a MOP doing nothing except inserting a script-generated G-Code,
f.e. moving to a specific position or start tool length mesurent, moving home, bring a beer ...

Manually I tried this :
- Fill MOP´s G-Code header and clear the Primitives ID-List => Error
- using a NC MOP, but this wants to read an existing file

Any ideas out there in CAMBAM world ?

Best regards

Feature Requests / Add a Keyboard Shortcut for adding/removing holding tabs

« on: January 10, 2019, 11:34:00 am »

Could you please add a shortcut ?

For it´s really annoying doing that by mouse again and again :
Aim nearby exactly to the item, right klick, drop down menu - select add or remove
a holding tab.

If you move the mouse out of the drop down menu, it disappears
and you have to re-start the procedure.

Best regards

Scripts and Plugins / Need help to start scripting (especially automated MOP creation)

« on: November 14, 2018, 13:47:11 pm »

Hi everybody,

my name´s Bernhard (54), once upon a time I´ve been studying informatics.
I am using a selfmade CNC Router for my hobby.
I´m from germany, so please excuse my poor english.
I´m using CAMBAM since summer of 2017 and after learning how to use I really like it.

Now I want to start writing a few simple scripts in order get a speedup in my workflow.

But where to start ... I see the examples in VB and Python, and I see an API
to control Cambam. The API´s documentation is a little ... let´s say thin.
Maybe I am not asking the proper questions.

So it´s hard for me to start. I am speaking C/C++,
but not really Python or VB. But I can read it, (often) understand an existing code
and I can change/adapt it.


My workflow is : Creating DXF file using QCAD, put it into Cambam an create the GCode.
Works usually fine.
But I see me doing always the same stuff in Cambam, after changing the DXF file
doing the same things again and again.


What do I want to program / automize ?

I have usually 2.5D stuff, not very complex.
So my idea is :

Putting some informations for creating the MOPs and their order into the DXF-file´s layernames.
(f.e. MOP order, milling depth, number of holding tabs, CAM-Style ...)
Using a cambam script parse this information and create the MOPs. Done.

Most things I realized by changing the demo-script "Automate.py" after
reading the whole internet to get snippets of information, the most from this forum here.


Now my questions :


- Python or VB ? (python seems to easier to me.)

- is there a way to get some Intellisense/Autocompletion during script writing ?

- Actually I am able create a new part and naming it by scripting.
  But I did not find a way to overload the active part´s CAM-Style.
  (dealing with MOPs I can)
 
- Using python I could not find a way to read out, alter and rewrite the holding tab´s properties of a MOP.
  (especially number of tabs and setting to "auto" 

 
If you want to, I can put here my rudimentary quick´n´dirty script.
And I have to create a simple DXF file for demonstrating.


I would be glad get a little help. 


Best regards

Bernhard
