Invert Y Axis and A axis #32

Closed 7cnc closed 1 year ago

7cnc commented 2 years ago

Hello, I need a suggestion on how to create a function in settings to flip pins from Y axis to A axis.

Example: $499=0 (Normal mode)

define Y_ENABLE_PIN I2SO(4)

define Y_STEP_PIN I2SO(5)

define Y_DIRECTION_PIN I2SO(6)

define Y_LIMIT_PIN GPIO_NUM_35

/ /Define ganged axis or A axis step pulse and step direction output pins.

if N_ABC_MOTORS > 0

define M3_AVAILABLE

define M3_ENABLE_PIN I2SO(7)

define M3_STEP_PIN I2SO(8)

define M3_DIRECTION_PIN I2SO(9)

endif

When changing the setting invert the pins Example: $499=1 (Invert Y and A axis)

define Y_ENABLE_PIN I2SO(7)

define Y_STEP_PIN I2SO(8)

define Y_DIRECTION_PIN I2SO(9)

define Y_LIMIT_PIN GPIO_NUM_35

/ /Define ganged axis or A axis step pulse and step direction output pins.

if N_ABC_MOTORS > 0

define M3_AVAILABLE

define M3_ENABLE_PIN I2SO(4)

define M3_STEP_PIN I2SO(5)

define M3_DIRECTION_PIN I2SO(6)

endif

In this way, using ioSender, I can use a probe on the rotating axis on cylindrical people, being able to map the probe.

An example for how to add settings can be found here. However, would it be better to add a M-code for swapping or do you need a setting so that the current configuration can survive a cold start?

You have to modify existing functions in driver.c to swap pins. E.g the step pins are set here.

What would an example of an mcodes.c "M100" look like with the function of replacing or inverting Step and Direction of the Y and A axes?

Or would it be easier to create a configuration parameter $499=1 to invert and in ioSender a Macro to change the value of $499=0 or 1?

Another way that would solve my case would be to enable the surface probing of the A axis, where the X axis represents the width of an alliance or cylindrical piece and the A axis the circumference. But I don't know if I would need to change it in GrblHAL or in ioSender.

I made the map for the Makerbase MKS TinyBee board, and it is working perfectly, I will make it available so that other users can use the updated map.

The change has to be made in ioSender - not something I want to attempt without a machine with a rotary axis.

... and it is working perfectly

Great, you implemented it via a M-code?

It still didn't work!

I'll try to simplify what I need, because the way I tried to do it wasn't good.

I need to create parameter $499 (Invert Axis).

$499=0 (normal mode)

define Y_ENABLE_PIN I2SO(4)

define Y_STEP_PIN I2SO(5)

define Y_DIRECTION_PIN I2SO(6)

define Y_LIMIT_PIN GPIO_NUM_35

$499=1 (inverted mode)

define Y_ENABLE_PIN I2SO(7)

define Y_STEP_PIN I2SO(8)

define Y_DIRECTION_PIN I2SO(9)

define Y_LIMIT_PIN GPIO_NUM_35

I need that every time I change the $499 setting the grblHAL changes the pins without needing to restart the firmware.

You have to modify driver.c to get it to work. Add a bool variable to control the pin swapping and a function to set it. Call the function either when the setting is changed or when a M-code is issued. IMO it is best to use a M-code as this does not write anything to flash...
