[BUG] Unresponsive & Erronous print processor

[gokhanozcetin]

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

Yes, and the problem still exists.

Bug Description

I am running a custom Marlin build on a custom LPC1768 board. Following code causes the print job to become unresponsive and commands including Emergency Parser inputs. It also fires M11() (air_evac_disable) at a random point in G-Code

Bugging Gcode attached as Test1.txt

Other codes work fine, attached as Test3.txt

Bug Timeline

No response

Expected behavior

• Freeze pin works
• Spindle output works
• Coolant control works
• Steppers operate perfectly
• Heating works
• P000 and R000 commands works

Actual behavior

• M524 does not work
• M112 does not work
• M commands through neither Nextion nor Serial works
• All commands sent via Nextion or serial are processed after print is completed
• A spurious M11 is fired in a random point in G-Code

Steps to Reproduce

• Cura and SD printing results same
• Disabled motor drivers to eliminate EMI - same behaviour
• Disabled endstops in printing - same behaviour
• Tried reducing speed, acceleration, replacing G0 with G1

So if I overwrite the latest bugfix files with your files in CutomBuild.zip, then I have you source base?
I have an unused LPC1768 lying around (MKS SGEN L V1), so I could give it a quick try...

You may not be able to run it because I changed almost every pin :)

You need to put M400 to wait for movement to complete before your M11.

Ok, Will try however the Test3 is another code which does not show same behaviour. Did you check that?

And also if it shoots out M11 by itself, it does not respond M524, M112 etc. although the emergency parser is enabled. With the Test3, I can throw M524 any time and it stops job before next move

Have tried M400 just before M11, now the device stops 7 or 8 lines before M400 and hangs. Blower output does not turn off since moves have not finished but it does not move to finish the moves

Yes, I noticed, I'm talking about a test bench setup (nothing attached), I just want to see if the code can run without hangs and doesn't switch off the M11 fan, which I can see from the board LED status. Let me see when I have time for it...

Yes, you can use the custom files and run a test. I have modified some other files to customize freeze function. Keep freeze pin grounded to run codes
