[BUG] POWER LOSS RECOVERY extruder squeezes out a lot of filament #26057

fedorovstas · 2023-07-06T13:00:34Z

Did you test the latest `bugfix-2.1.x` code?

Yes, and the problem still exists.

Bug Description

After POWER LOSS RECOVERY hotend and bed heated up, x and axis doing auto home and go back to the place where it finished printing. Then extruder squeezes out a lot of filament and there is a large influx of plastic. After that printer continued his work.

Set the load and unload values to 0. Nothing changes. Problem similar to this bug report.

ThomasToka · 2023-07-25T17:39:44Z

I can approve this.

Set advanced pause purge and retract to 0, set also

    #define POWER_LOSS_PURGE_LEN      0 // (mm) Length of filament to purge on resume
    #define POWER_LOSS_RETRACT_LEN    0 // (mm) Length of filament to retract on fail. Requires backup power.

behavior is the same. after reaching the print position it purges a lot very fast.

cant find it to be honest in powerloss.cpp .

Edit: Got it sorted. I had something from the Ender 5 s1 PR included. reverting to the bugfix-2.1.x fixed it.

Edit2: see following comment. its stil there.

Sorry for the wind.

ThomasToka · 2023-07-26T09:31:11Z

@fedorovstas is that what you see also?

@ThomasToka No. I will add video later.

Sometimes it start squeezing when hotend start moving from home.

Abasz · 2023-09-23T08:41:14Z

I have the same issue ever since. The problem is that the current_position values get overiden by the ISR, so when the "E" position is reset by this line PROCESS_SUBCOMMANDS_NOW(TS(F("G92.9E"), p_float_t(info.current_position.e, 3))); its set to zero, and when the new line is read from the SD card to the correct value, the difference is extruded.

I fixed this by changing two lines:

At the begining of the resume() function I create a value copy of the info.current_position and then I use this copy to reset the "E" position later on instead of the info.current_position:

void PrintJobRecovery::resume() {
  const uint32_t resume_sdpos = info.sdpos; // Get here before the stepper ISR overwrites it
  const auto current_position_copy = info.current_position;

//...

PROCESS_SUBCOMMANDS_NOW(TS(F("G92.9E"), p_float_t(current_position_copy.e, 3)));

//...
}

This fixes this issue. I am not sure if this is the best approach and I not able to test it apart from an Ender 3 (4.2.2 board) but I assume it should work for you too.

thx. i fixed this already in my fork and reroute to G27.

ThomasToka@64c7975

Thanks, actually re-routing to park is a very good approach, thanks for the suggestion! I added a proper UI feed back and it works great:

  gcode.process_subcommands_now(F("G27"));
  ui.pause_show_message(PAUSE_MESSAGE_WAITING);
  wait_for_user_response(0, false);
  info.current_position = current_position_copy;
  ui.reset_status();
  ui.return_to_status();
  planner.synchronize();

fedorovstas · 2023-09-27T09:40:21Z

@Abasz it works. Thanks!

fedorovstas · 2023-09-27T18:57:07Z

I have another problem. After enabling PLR in some zone of printing extruder start make ripples on my print. If I disable PLR in firmware everything is OK. I use the same gcode in both cases.

Are you using frequent save of the PLR to the SD car? I had similar issues when I had the PLR file to be written in every 5 seconds. The board did not like it especially when there was a lot of very small movement, and the machine hang above a spot for a half a second

fedorovstas · 2023-10-01T19:11:47Z

@Abasz i use SD card. Marlin use POWER_LOSS_MIN_Z_CHANGE to saving PLR file. In default it set 0.05 i increased this value to 0.1 and everything work good. Thank you very much!

mechano · 2023-11-22T23:52:32Z

@Abasz it works. Thanks!

When will it be released?
I've same issue on Kingroon KP3S 3.0.
The version KP3S Pro and KP5L hasn't this problem.

It's strange because all of this printers share the same Robin Nano 1.2 clone board with GD32F303 and 2225 drivers.

mechano · 2024-01-08T19:36:36Z

I've compiled a 2.1.2.x-bugfix 20231229 version for an MKS Robin Nano 1.2 and it has the same problem.

I've compiled a 2.1.2.x-bugfix 20231229 version for an MKS Robin Nano 1.2 and it has the same problem.

See #26365. The PR / fix has not been merged.

ThomasToka · 2024-01-08T20:15:36Z

additionally i want to say that without my initial commit it is not solved. the additions thinkhead made do not work for me reliably. did not test the last state. but i am sure my fixes in #26365 work and solve all of this.

thinkyhead · 2024-01-10T23:20:40Z

We'll have #26365 merged very soon. Cheers!

mechano · 2024-01-13T20:15:21Z

When will it be merged?
How can we know it has been merged?

ThomasToka · 2024-01-13T21:12:16Z

it’s merged already.

  info.current_position = current_position_copy;

Thank you, I applied the basic idea of this on Marlin bugfix-2.0.x, and worked like a charm, now I can recover from power loss without a hassle
