Delay in tool change spindle start #1102

Open leofaoro opened 5 years ago

leofaoro commented 5 years ago

Hello I use the tool change feature, and when I am done with putting the new tool in, the spindle starts and quickly moves to the workpiece without having spun to the target spindle speed. Would you please add a delay command of 5s or so so the spindle can speed up before plunging into the workpiece? Thanks

Good point! Do you dare to create pull request? :-)

leofaoro commented 5 years ago

While I know some python, I have never made a contribution. I'd love to learn this.

Look at the file cnc.py, it deals with the tool change in the sector: code to change manually tool

I think this is the prerogative of G-code and not the program B-cnc.

And if the tool is the filament? That at program delay its overheating is possible (for example in pyrography)?

Thanks. I know where to find this. I have to learn the process of using GIT.

hmm. this is true, but AFAIK bCNC is not for 3D printing, but I may be mistaken. I know using it with laser is also supported. I'll let the maintainers decide. I added a pull request.

B-cnc is used to send G-code, including for 3D models (engraving, burning, printing).

G-code should be sent without any changes. When creating a G-code, its author (automatic script or otherwise) should take into account all the features of the machine in G-code.

I guess the pause can be optional selectable in UI...

Thanks and congratulations for contributing a plugin. Maybe create a new field to choose waiting time before starting spindle. In the probe / tool change sector or in the machine configuration.

Thanks Mario, but honestly I contributed exactly 1 line of code :) I am just getting started with python programming and contributing to OS projects.

About your comment: yes that would be ideal. Do we have a place where this field should go by default? I wouldn't want to clutter a place where it's not wanted.

leofaoro commented 5 years ago

I modified my version to include an option to set the time for the spindle to wait. I am away from my CNC so I can't test. Can I submit as a pull request and so someone can test before merging? Newbie here so just learning how to collaborate. thanks

Hi, I am also interested in this feature. I do not have an automated tool change but my spindle has a very slow soft start which cannot be switched off and if the position is close to the first "contact coordinates", it is not sufficient time to spin up.

leofaoro commented 5 years ago

It’s been pulled into master with 5s delay.
