GrblGru: Free CAM and 3D-Simulation for mills and lathes

[LH4PI]

@GrblGru

Some additional info

I check all 3-axes machines with moving working tables instead of have the table stationary in the y-direction . I find beside the cnc1310 , also the Sprite and T8_cnc machine model have the similar problem .

[GrblGru]

@LH4PI

Could find the bug with the help of your good description. In the new beta version V3.44.11 it should be fixed.
Thanks for your help to improve GrblGru.

[GrblGru]

Sorry, I forgot to change the limits in the new version.

@GrblGru

Thanks for the fix 3.44.11. I was able to get cnc 1310 machine model to be expanded to the size of 3018 ( even if your comments in #279 is valid)
"
I test to engrave my logo "LH4PI" using the home position according to your definition (based on prefered home =0,0,0 for the three axes placed at the Bottom Right Rear (from the user manual ) and then move the axes to "Bottom(Z) Left Front" corner and then set this location to the actual working position using the "origin" knob. (see Picture) Then I run the gcode for the logo. without any " red warning coordinates ". Thanks again .

Some additional notes that I am sure You know in this beta ;,


it seems like;

the stock box is not functionally ,

the possibilities to save the 3018 new machine setting is not functionally but works if I use the name "1310 "

save projects is not active

------------------------------------------------------

Question :

How do I set up the grblGru interface so the program stops running the code if the limit switch is activated , I only could see them be activated in the code in the controller window but he machine keep on running the code even if the $21=1 was set. Probably I have missed some setting , please help .


-------------------------------------------------------

Some suggestion based on the interface to be able to "see " the status of some input pins to make it easier to understand whats going on when the user try to set up the hardware for the input pins that are supported in the Ramps 1.4/grbl-mega-5x/GrblGru 4.44 and further versions.


To be able to give you feedback I made a test set up only using the ramps 1.4 card on top of the mega 2560 card (same as the version You use ) (see picture ) and some switches to see what response was send back by the controller software ;

I could then to study the control feed back characters from if I send a grbl command and then study response of x,y,z and probe switches , see picture where I have pressed the x,y, and z and also have had the probe pin (A15) connected to ground during the run of the gcode


I believe , it is only when I send a command (like "State") you can see what switches are activated in real time .





Suggestion 1

Could it be possible to be able to have a more flexible controller window to flip on/off knob to not reset the controller window for single commands. In this way it is easier to follow a sequence of input signals triggering the controller and see them all. The clear knob already exist.

suggestion 2

Make a l status hardware input window (as a example with small simulated leds, that lights up when triggered ) where the supporting inputs (X,Y and Z end stops as well as A and B, probe switch safety door can be be monitored (by sending as an example the status command all the time until the user wants to stop to evaluate the triggering sources )

@RgblGru

Sorry

it seems like;

the stock box is functionally , but I only use a 2D engaver G-code so of courcea I couldn't see a box

It seem that the 2D scaling of dxf files etc is missing from this Beta ,

[GrblGru]

- The menu item "Save Project" is only active when geometry data is loaded.

- The same applies to the Stockbox display.

- To be able to save machine 3018 you must first create a machine 3018 and load the STL objects.

- There is no possibility to stop the machine if a limit switch is passed. Only the red display appears.
This allows you to see in one run where (there can be many) collisions occur.

- The 2D Scale button is missing, because I am currently replacing it with another function in the new beta. ( Right mouse context menu in the 2S view - 'Open Editor')
I will describe it if everything works

Your ideas for the display of the input signals are certainly useful. But you can control many different processors with my program.
Currently these are GRBL, TinyG, G2CORE and MEGA-5X. That's why I don't want to commit myself to a certain function of a single processor.
The interface should be completely processor independent. So when you open the controller window, you are talking directly to the connected processor.
GrblGru only offers you the infrastructure for this. I hope you have some understanding for this.

In case you want to control your limit switches, it might be better to use one of the other Gcode senders.
Most of them concentrate on one processor and provide e.g. also plain text displays for the parameters. For example, 'X Max rate' instead of $110 (in case of GRBL)

@GrblGru

Thanks for answering

I understand your point to not be to details of a certain hardware , and instead concentrate on the overall picture . My point to read more than one command answer in the commande window before the information is erases is such more overall feedback.

[GrblGru]

@LH4PI
I still have questions. It might be a bit more comfortable to exchange information via email.
If you agree, please send me a private forum message with an email address. I will then contact you.

Hi GrblGru

Version 3.44.13 does not show gcode when clicking on the green “Start” button.

I sent you, a private message PM with titled “time zone”.

[Armando]

WOW!

Excellent work, new features, very good.
Hi guys, download version 3.44.16 and help GrblGru solve problems.

Release notes V3.45

Lately I have unfortunately not been able to document the changes of GrblGru.
In fact, a lot of internal improvements have been made in the meantime, which will put the further development on a solid base.
But hopefully there have also been some improvements, especially in the area of simulation and the display of the tool path.
Also some new machine models like a new styrofoam cutter, a grinding machine or different robot arms have been added.
Finally the new editor mode has been added, which allows to scale, rotate and reposition selected geometric objects (DXF or SVG).

I hope that I will be able to deliver the corresponding documentation in the near future.
In the new video I have therefore dealt with the robot arms, which can be produced with 3D printers and are therefore quite cheap.

Have fun with GrblGru

Sorry, I forgot to change the limits in the new version.

Sounds cool. I'd like to try it out. FYI the links to dropbox in the first posts of the thread are dead.I skipped to the end of the thread to see if I could find fresh links. I haven't found one yet, but I'll keep looking.

If you could put a link in the signature to your account, it would probably be helpful. It should update in all of your posts if the link ever has to change. Thanks, look forward to trying it out.

[GrblGru]

Sorry, Dropbox has changed their business model and it was no longer possible to provide a download.
I have had a website at www.GrblGru.com for quite some time now, where you can download the program for free.

[Glass3cat]

Thank you for the great software.
from Japan.
I created a machine model for CNC3018.
It may be due to Japanese localization, but the position of the stock box is shifted.
In V3.44, this is normal, but in V3.45, the polarity of Limit on the Y-axis worked in reverse.

If there is a way to paste an image or file into this thread, I will send the image or file.

[LH4PI]

Hi Glass3Cat

I have added a 3 d cad model of 3108 and a 5 axis version 3018AB of the same base model made myself and with help of grblgru we have added a simplified model of these two models included from version 3.45.2. I believe that the movement of the base is correct . I have uploaded a pdf of the original model I created so you can see it in more detail compared to the model in GRBLGRU .

It should be interested to know if your model is similar to mine .

[Glass3cat]

Hi LH4PI

I downloaded Ver3.456 and confirmed it.
The 3-axis CNC3018 worked correctly.
Thank you very much.
When only A axis was added to CNC3018, A+.stl, s1+.stl, s2+.stl, s3+.stl did not work with Ver3.456 and Ver3.45. Ver.3.44 works but the movement is not normal.

[Glass3cat]

If you can log in to facebook, you can see my CNC3018 model at the url below.
It is a freecad file, but you can download the CNC3018.fcstd file.

@Glass3Cat & LH4PI

I am sorry to be late for this discussion.
Thanks to LH4PI for your help.
Have you solved all problems or are there still open questions ?
Is there anything else I can do?

[Glass3cat]

Thank you for uploading Ver3.45.7.
When importing a DXF file, the image is shifted from the tool position.
Ver3.44 was able to align with Scale 2D data.
2D icons are not visible in Ver.3.45 or later.
Can I add 2D icons?

[BehrElec]

Agree with GLASS3CAT about scaling 2D data.
Some icon's haven't a proper. I can help with the text file. Please send procedure to my email address: behr@icon.co.za
