Tested Firmware: 3.4.4 ->ok 3.4.5 ->crash 3.4.9 ->crash 3.5.0-pre4 ->crash 3.5.0 ->crash

[MitchBradley]

I cannot duplicate the problem. I adapted your config for use on MKS DLC32 v1.1 - the closest board that I have to your setup. To do so I had to change the GPIO and I2SO pin assignments. The config file is attached. I then installed FluidNC v3.5.0 and, from WebUI, clicked on the Home X button. I then pressed and released a switch connected to the X limit pins, then pressed/released again during the slow approach phase. It worked exactly as expected. I also tried using $HX from FluidTerm, with $message/level=debug so that I could observe the homing phase reports. Again, it worked correctly. issue526.yaml.txt issue526.ss.txt issue526.hx.txt

I also tried with the X homing switch set to active high (NC). It worked.

[MitchBradley]

I have a guess about what might be happening. The crash backtrace indicates that Core 0 is in a pin interrupt handler, and the crash is caused by a watchdog timeout. That could happen if the interrupt handler is firing continuously so that the idle task has no time to feed the watchdog. The active state of the limit pins - high - suggests that the limit switches are normally closed, which means that the limit inputs are relative immune to noise when the switch is inactive. Then, when the limit is reached during homing, the switch opens and the impedance of the circuit is much higher and thus more susceptible to noise. If the limit circuit is picking up noise when the switch is open, the limit interrupt could be firing over and over, saturating that core with interrupts.

One way to check this would be to replace the X limit circuit with a switch on a very short wire. Test homing by manually operating the switch. If it works correctly with that test, the real limit circuit is probably picking up noise.

The Tinybee board has RC filters on its limit inputs, but the schematic does not show the component values so I cannot tell how effective those filters might be. Even if I knew, this ticket gives us no information about what types of limit switches are used, how they are wired, what sort of interfering signals might be present, how possibly-interfering wiring is routed, how the different power supplies are tied to ground or noise filtered, whether or not the laser supply is running when the problem occurs...

[Skorpi08]

it has optical endstops as shown on this website. http://donsthings.blogspot.com/2016/06/k40-optical-endstops.html?m=1 I can test it later with DLC32.

[Avataar120]

I do confirm that those optical endstops are generating a LOT of noise on the ESP32 inputs (and not only when reaching endstops) Before designing my own board for ESP32 GRBL and now for FluidNC, I have experienced some difficulties at first with standard shields that were not equipped with RC filters (false positives mainly) In my personal design I have integrated RC filters and I have no more issues

[MitchBradley]

Optical endstops can trigger from ambient light. Some kinds of lighting pulsates at high frequencies that could potentially cause rapid-fire triggering. When the interrupter is not in place, you would not experience the effect because the LED is keeping the optocoupler turned on continuously. When the interrupter is in place, ambient light leaks in and retriggers over and over at the pulsation frequency. You might be able to shield the limit switches somehow by putting some sort of box over them.

[Skorpi08]

The Problem is not the Endstop. I have also changed the endstop and another TinyBee Board, don't help. I have changed on X Axis limit_neg_pin: gpio.33 to limit_neg_pin: gpio.22 and it works.

On Y Axis it works with limit_neg_pin: gpio.32

As I have already mentioned, with the 3.4.4 it works.

The Tinybee board has RC filters on its limit inputs, but the schematic does not show the component values so I cannot tell how effective those filters might be. This is on TinyBee This is on DLC32

For reference, here is an excerpt from the Tinybee schematic

tested with DLC32, no Problem.

I also have a tiny bee and the optical pins don't work properly, give out alarm , limit_all_pin: gpio.22 does that help without a macro?

[MitchBradley]

There is a difference between the MKS DLC32 and MKS Tinybee input circuits. DLC32 has while Tinybee has

The additional Tinybee components provide protection against spikes, particularly the reverse-biased diodes (D22) that connect to +5 and GND. The Schottky series diode (D31) makes the input 5V tolerant, by disconnecting the input if its voltage goes above about 3.4V. I wonder if that series diode is contributing to the problem by changing the circuit behavior on a low-to-high transition? It might also be affecting the bias conditions of the optical sensor under certain conditions.

One way to test that conjecture would be to bypass that diode by connecting a resistor - something like 10K - from 3.3V to the input pin.

Nothing helps. With pin 33 it does not work, with pin 22 it works fine. Something must have changed in the 3.5.0, because with the 3.4.4 it also works with pin 33.

[MitchBradley]

A lot changed between 3.4.4 and 3.4.5 - we upgraded to the new version of the Arduino framework, which involves a switch to the new version of the ESP-IDK core firmware and a newer version of the C++ compiler. We are still finding differences and problems in that underlying code. Somebody sent me a Tinybee for testing but it has not arrived yet.

[MitchBradley]

I don't know if this will help but it is worth a try https://github.com/bdring/FluidNC/releases/tag/EventQueueTest
