[BUG] Unable to change filament during print

[xhejtman]

I am unable to change filament during print.
I pause print. I do unload filament, load filament. I'm back in the main menu -> cannot resume print right now. I request print, it asks for continue. I select continue. It does not print I have to select resume, but ok. I resume and Z axis is completely messed - it resumes the print in completely wrong layer.

Using commit 9148ffe.

Hi.

9148ffe is only changing the ReadMe at the front page and does not change any code which is loaded to the TFT. Checking the two other tickets you opened I would recommend to reset the TFT using the reset.txt file OR the menu on the TFT, AND to upload the firmware recommended by digant73.

Check your 3 tickets after that and let us know.

Thank you

I can confirm there's something borked about Pause/Resume during printing. In my case after Pause the printing head goes almost to Home then returns above the printing part. I have to press Resume and wait for a purge than hit Continue on a popup than hit Resume again. It's not really nice to purge above a printed part.
This was observed while air-printing form onboard SD.

Are you also printing from on board sd?

[xhejtman]

nope, I print from SD from TFT

Tested with TFT USB, Pause/change filament/Resume working as expected. Paused, removed filament, after inserting new filament it loaded automatically and resumed printing automatically.

Any news?

So, pause/unpause returns to correct layer. However, as of commit 9148ffe, menus are a bit rearranged, so I cannot run unload/load gcode - it is moved to the Move menu which is not available during Pause. I can extrude though and as it does not change layer height, it is OK, you only have to match pause retract length during changing filament.

Like I wrote before. This commit only changes the documentation and not the code itself. xhejtman <notifications@github.com> schrieb am Di. 29. Dez. 2020 um 13:27:

Sorry for confusion, I reference the commit as the HEAD I use. I do not mean that that commit is wrong in particular.

[kisslorand]

So, can you change filament?

[xhejtman]

technically, I can. But that nice menu for unload/load filament (via gcode m701/702) is not availabe for me during paused print, I can only extrude manually and it works.

[kisslorand]

Yeah, I thought about Load/Unload to be available during print and Pause. What if Babysteps become Load/Unload button when print is paused? How does it sound?

[xhejtman]

I think Babysteps are important. What about moving Extrude into Move menu and Load/Unload remove from the Move menu instead of the Extrude that is available during Pause? I makes more sense I guess. Extrude is just moving the extruder. Load/Unload it something different..

[kisslorand]

I found an icon that could be replaced. When you press "More" there's a "Terminal" button. It can be replaced by "(Un)Load" since "Terminal" can be found also if you press "Machine".
