Помогите с кодом.

Хочу сделать швейную машинку для вышивания..
как подключить (датчик индуктивности или датчик холла )для установки поднятия иглы ? и прописать его в прошивке
чтоб по команде в gcode m555 двигатель остановился и провернулся до замыкания датчика . ?!?

I want to make a sewing machine for embroidery..
how to connect (inductance sensor or hall sensor) to set the needle lift? and register it in the firmware
so that, at the command in gcode m555, the engine stops and turns until the sensor closes. ?!?

You will have to write a plugin for that.
If your board has registered auxillary inputs (preferably interrupt capable?) you can use the ioports API to read the input. This template reads inputs via interrupts, you may also poll the input while waiting.
Add M555 handling to the plugin in a similar way as [this example.

stm32 3 axes are used, there, there are also outputs for 2 axes. Is there any instructions on how to use and configure these plugins. I'm not good at programming. it turns out I take a pin with stm32, enter an additional "M * command and when executing Gcode, the command will be executed according to the written conditions and after that it will start executing the following lines of gcode....

Could you please help with writing a plugin, I have no skill in this.
you need to start some kind of command "m" and when using it in gcode, so that the engine at low speeds looks for the position of the sensor until an input signal is received, then it stops and gcode continues to be executed.

Is there any instructions on how to use and configure these plugins.

For the templates instructions are usually in the .c file header. For "active" plugins in hosted separate repositories in the associated readme. Some general informatin can be found in the Wiki.
For the templates and any you write yourself just copy (or create) a file in the source folder (where main.c is located) and recompile - the only requirement is that a function named my_plugin_init is present, it will be called on startup.

M555 is new for me, is this generally used by embroidery machines? If so do you have any links to information?

[logvinov-ivan]

no, I wrote m555 as an example to make it clear in gcode , otherwise you can use any command

[terjeio]

I wrote m555 as an example

Ok, then you can first try with M66 - wait for input, use the $pins command to check if P0 (Aux0) is available.
E.g. M66P0L2Q1800 will stop execution and wait for a falling edge with a timeout of 30 minutes.

[logvinov-ivan]

by gcode, the engine will turn off and m66 will then wait for the sensor to work on the pin ?! so the engine should reduce to 10 revolutions and rotate until it finds a signal from the sensor, after which it continues to move .. according to the gcode program

[terjeio]

by gcode, the engine will turn off

Motion will stop and wait for the sensor. If you are using the spindle signal for something and want to stop that then M66 will not disable the spindle signal.

so the engine should reduce to 10 revolutions and rotate until it finds a signal from the sensor,

Is this in the gcode? And is it the same sensor as for the first step?
Do you have example gcode that shows the sequence? With comments if possible.

[logvinov-ivan]

there is no gcode, it will just execute commands, after the execution has passed, the engine should spin slowly to find the sensor and stop, it turns out that the needle will come out of the fabric, and will not tear the fabric after gcode continues to work.

[terjeio]

there is no gcode, it will just execute commands

You lost me there - execute what kind of commands? grblHAL understands a number of G- and M-codes plus some $ system commands.
It is possible to add parsers for other command sets, as I did for the HPGL plotting language.

How are the commands generated? By a program? Made by you or generally available?

[logvinov-ivan]

publicly available.
yes, everything is like a plotter, just add parsers so that the electric motor can tighten the needle, that is, it will turn until the sensor is triggered, stop and then begin to execute gcode., this is in order not to take off the needle and tear the fabric, you need to track when moving the axes, the upper position of the needle.

[logvinov-ivan]

What will happen.
x-axis
y-axis
hall sensor motor
through Ink / Stitch I will generate a code for embroidery.
I will run the code through grblhal
the axes will start moving along the program. after the program is completed, you need to move, but since the needle may remain at the bottom and when moving to another point starts, it will lead to a tear in the fabric and a broken needle. that's why I want to track the position of the needle before moving to another place. To allow movement, the sensor must allow movement, that it is closed and you can perform movement or further execute gcode.

[terjeio]

Do you have any links?

just add parsers so that the electric motor can tighten the needle, that is, it will turn until the sensor is triggered, stop and then begin to execute gcode

So there is defined sequence of actions that has to be taken when executing the new M-code, not only a simple wait?
Perhaps a bit similar to the toolchange sequence(s)? Motions, wait for probe input, motions, wait for input (cycle start), motions...

[logvinov-ivan]

У вас есть ссылки?

просто потом добавили парсеры, чтобы электродвигатель мог подтянуть иглу, то есть она крутилась до срабатывания датчика, останавливалась и начинала запускать gcode

То есть определена последовательность действий, которые необходимы при выполнении нового М-кода, а не простое ожидание? Возможно, это немного похоже на последовательность(и) смены инструмента ? Движение, ожидание ввода датчика, движение, ожидание ввода (начало цикла), движение...

what you need, but here the movement is performed by raising the axis of the stepper motor, and I have an asynchronous one, to find the sensor you need low engine speeds, PWM control.

[logvinov-ivan]

And how to collect all this in the firmware ?! is it possible with mega2560 and shield ramps 1.4?

[terjeio]

Looking at this video it seems to me that want you want is to run the retract step (pulling the needle up) until a sensor is struck and then continue?
This could be achieved by using a probing sequence for the retract?

is it possible with mega2560

Sorry no, grblHAL does not run on 8 bit processors.

shield ramps 1.4

Some boards supported by grblHAL could use this if Ramps 1.4 is similar to 1.6?
