Stepper disable during jog

DEST1981 commented 2 years ago

Hi. Release v3.3.1

I set in config.yaml direction_pin: gpio.22

axes: shared_stepper_disable_pin: gpio.13:high

x: steps_per_mm: 100 max_rate_mm_per_min: 4000 acceleration_mm_per_sec2: 200 max_travel_mm: 400 homing: cycle: 2 mpos_mm: 10 positive_direction: false

  limit_neg_pin: gpio.35:low
  standard_stepper:
    direction_pin: gpio.22:high
    step_pin: gpio.21
motor1:
  null_motor:

But it is not work. The direction_pin: gpio.22 not change status low\hi if i chande direction.

MitchBradley commented 2 years ago

How are you testing the state of the direction pin? What is your hardware? What is the rest of your config? What are the startup messages on the console?

It is impossible to solve a problem with the very small amount of information that you provided.

bdring commented 2 years ago

Please post your boot messages.

I changed the direction_pin: gpio.22 to gpio.4 and everything works correctly. Hardware changed too.

bdring commented 2 years ago

You skipped all the meaningful stuff in the boot messages. gpio.22 should work. Try to use gpio.22 for something like mist coolant to see if it is a hardware issue.

MitchBradley commented 2 years ago

Maybe there is a short on the GPIO 22 wiring.

DEST1981 commented 2 years ago

The machine worked fine with Grbl Esp32 firmware. Yesterday I decided to change the firmware to FluidNC.

MitchBradley commented 2 years ago

If you want us to engage with this problem you will have to give us lots of information, instead of doling it out one drop at a time. For example

we need all the boot messages
"oscope" is a weak answer to "how". We need to know where you measured (right at the GPIO pin, or elsewhere on the board). We need to know the commands that you used to change the direction pin value. Did you try measuring with the ESP32 unplugged from the board?
Information like "it worked fine with Grbl_Esp32" should have been provided at the outset, not after a lot of prodding
Since it worked with Grbl_Esp32, it would have been helpful if you had attached the machine.h file. If the FluidNC config file was auto-generated, a pointer to the issue that generated it would suffice.

We would like to help, but we are very busy. When you give us too little information, it wastes everybody's time because the search space of possible problems is very large. Asking questions over and over is very time consuming, and also very frustrating.

DEST1981 commented 2 years ago

Dear Mitch. English is not my native language. If you don't have time and you're also very frustrating, just say fuck off. Now for the problem. I had a working CNC on ESP32-GRBL. I recently saw that you are developing a new ESP32 project for a machine tool. I used FluidNC, I ported the settings from machine.h to config.yaml. Then the X axis stopped working. I connected the my analog oscilloscope to the ESP32 pin and noticed that when the direction is changed, the state of the pin does not change. Then I removed the board, cut the track and connected it to the gpio.4 pin, and everything worked fine.

bdring commented 2 years ago

Both Mitch and I are out of town and cannot easily test hardware, so we need as much information as possible. We have successfully used all of the ESP32 pins for things, so hearing that one pin is acting differently seems strange. Please try testing gpio.22 with another function like mist coolant.

coolant:
  flood_pin: NO_PIN
  mist_pin: gpio.22
  delay_ms: 0

The first thing I notice in the boot messages is you have a repeated line, with Motor0.

[MSG:INFO: Axis X (10.000,410.000)]
[MSG:INFO: Motor0]
[MSG:INFO: Motor0]
[MSG:INFO: standard_stepper Step:gpio.21 Dir:gpio.22 Disable:NO_PIN]

Does the one that works with gpio.4 also have that repeated line?

Please paste the config file that generates the problems here.

mist_pin: gpio.22 work correctly. The state of the pin change hi/low.

bdring commented 2 years ago

It appears that something has changed. Your second post of the gpio.22 boot messages version no longer shows multiple instances of Motor0.

Does the gpio.22 version now work?
When it did not work, what was the behavior of the motor. Did it not move at all or only move in one direction regardless of the direction specified.

DEST1981 commented 2 years ago

Motor move only in one direction regardless of the direction specified.

bdring commented 2 years ago

Can you explain the change in the boot messages?
Is the gpio.22 version working now?

Please note there are 2 questions here and answer both in your next reply

I will look into that problem. There was a change to the idle code not so long ago. Maybe it broke something.

bdring commented 2 years ago

You could try adding a duration to the disable_delay_us: config item. The default is 0

Some of the cheap TB6600 driver boxes are notoriously slow to respond to signals.
