Marlin bugfix 2.0 Dual Extruder problem

I do not know if I am the only one with this problem, but after several hours of searching and I found no solution so I come to ask for help.

I have an original board CR-10S with the stepper driver for the second extruder.

I downloaded marlin bugfix 2.0 I made the settings for two extruders compiled and flashed the board.

I then sliced ​​a file to print with the E1 extruder. The printer warms the bed then heats up the second extruder hotend and then starts printing but the second extruder motor does not work.

I tried several times until I decided to print something small and let the printer go all the way to the end. The printer thinks it is printing, but no filament exits because E1 motor doesn't move. When it finish printing the printer turns off the hot bed but the second extruder hotend remains at the same temperature until I manually turn it off.

I have also tried with Marlin dev 2.1 and it happens the same but with exactly the same G-Code in Marlin bugfix 1.1.9 everything works fine.

Can anyone help?

Hello everyone.

I still can't figure out what's the problem with Marlin 2.0 but I'm unable to print with the second extruder. The first extruder works normally.
I attach my configuration.h and configuration_adv.h files here if anyone wants to have a look and try to help me.

Thank you all

Thank you Roberts_Clif for trying to help me. I appreciate that very much.
I did what you suggested and set the board MKS_Base_14, compiled and flashed the printer.
Unfortunately it did not solve my problem. Exactly the same thing happens.
It must be some bug in Marlin version 2.0 because with version 1.1.9 with the same settings it works perfectly.

I was using Marlin 1.1.5 and really there was not reason for me to change to Marlin 1.1.7, Marlin 1.1.9BF or even Marlin 2 but just wanted experiment.
Post Marlin 1.1.9 Configuration.h and Configuration_adv.h.

You know that when you Upgrade your firmware from One version to another you need to reload firmware settings to memory.

Using M502: Factory Reset then M500: Save Settings or the newly loaded firmware will use the older firmware settings.

Thanks again.
I initialize eeprom every time I update the firmware.
Here are the configuration and adv files from version 1.1.9.
I hope you find something that is passing me by.

This might Take a while as Monday is coming soon.

No problem. I understand.
I greatly appreciate your help.

When I compile your configuration it shows that you are using over 71% of the resources.
A warning appears when this happens on Marlin 2 showing you are running low on memory.

Could you zip your Marlin 2 upload to a share site and post me a link.

Computer Programmer / Electronics Technician

Sure I can.
I uploaded Marlin 1.1.9 and Marlin 2.0.
Thank you for your help.

Here are the link: [gofile.io]

I have went threw your code I see no Code errors, I still get the a Low Memory
This could be fixed by removing a single line that is really not needed. Try to remark out the Sort Alpha see if this helps.

//#define SDCARD_SORT_ALPHA

Still looking !!!

You're right. I removed SDCARD_SORT_ALPHA and no longer have the low memory warning. Thanks.

No hurry. Wishes of a happy new year.

Did you get this sorted yet??
I came across your problem while searching for help with my own....

Have you tried comparing the 2 config files with Winmerge... it allows side by side comparison of the 2 files... I started going through your config.h and there are a couple of things that are commented out in the v2 that are not in the 1.1.9

I haven't gone through it all (I have my problems to solve!!) but it might be a way to narrow down your issues...
