Marlin: Ender-4 Printer config incorrect

[lucazader]

Hi All,
I have just got an ender-4 printer. Working great so far, just wanting to put standard marlin on it.

According to the issues:

9160 and #9188

that were merged 5 days ago, Marlin now supports my printer.

However it looks like the board that comes with the ender-4 is different than the board used by the ender-2. Not sure if it previously came with a different board.
Picture of board that arrived with my printer:
https://goo.gl/nUFxhe.

The board is based on the ATMega2560, with non integrated drivers and a few other things.

There is a guy (Skorpi08) over on the http://www.3d-druck-community.de forums that seems to have created a config file etc for this board.
http://www.3d-druck-community.de/thread-19102.html

Here is a gist of the relevant files as downloading from the forum requires signing up.

Looking at a diff of the config files there are quite a few. The main one is that the Ender-4 is a corexy printer.

Anyway just thought I would bring this up here even though it is closed and merged. Rather than have someone use this config without checking.

Please let me know if you should make a PR containing the new/correct config for this printer.

It now has BOARD_CREALITY_ENDER. If the config is now working then this can be closed.

Hi @thinkyhead

Thanks for the reply.
As i mentioned in the code, the config for BOARD_CREALITY_ENDER is incorrect if intended to be used with a Creality Ender-4

This config assumes that the ender 2 and the ender 4 printers:
1) use the same PCB
2) use the same mechanics

This is not the case.
The PCB is different, with replaceable stepper drivers and based of a ATMega2560 which is different from the board that comes with the Ender 2.

The printer uses an H-Bot printer style of mechanics.
Which from much understanding should mean that one of the #define COREXY or #define COREYX defines enabled in the example Configuration.h

In the mean time i would suggest that this config should be changed to not refer to the Ender 4 at all, and separately i will create a PR to add the Ender 4 as a separate printer once I have tested out the configuration on my own printer.

Thanks,
Lucas

Awesome. Looking very much forward to it! Marlin 1.1.9 is due to be released in a couple of days.

Probably worth mentioning somewhere that Ender-4 and CR-8 have exactly the same mainboard.
I'm not so sure whether the configuration is different or not. I did not manage to get the configuration from this PR to compile, but I have CR-8's original firmware backed up.

I did not manage to get the configuration from this PR to compile

What error did you get? Testing with bugfix-1.1.x?

[D-side]

@thinkyhead yes, it was the base branch of the 1.1 PR, bugfix-1.1.x.

So just to be safe of my bolted-on mods in an attempt to fix this, I properly cloned the repo (was working with a ZIP until now), copied the configs:

cp "Marlin/example_configurations/Creality/Ender-4/*" "Marlin"

And hit "build" in Platformio. Here's the output (minus some useless noise):

PLATFORM: Atmel AVR > Arduino Mega or Mega 2560 ATmega2560 (Mega 2560)
SYSTEM: ATMEGA2560 16MHz 8KB RAM (248KB Flash)

Okay, now having slept for a good while I actually got it to compile 😅

[k0d3x8its]

Can you provide the corrected code that compiles? This is my first 3D printer kit, and I can’t seem to find any information about the Creality Ender 4

[thinkyhead]

@k0d3x8its — Marlin bugfix-1.1.x and bugfix-2.0.x both include an example configuration for Ender-4.

[willysmoose59]

Is there anywhere else to get this config file? I've been waiting to get confirmed on the that site and still nothing. Replaced my hotend on my cr-8 clone and need to load the firmware corrections.

[D-side]

@willysmoose59 as mentioned above, it's available in bugfix-* in this repository.
Here are the ones in bugfix-1.1.x for instance: https://github.com/MarlinFirmware/Marlin/tree/bugfix-1.1.x/Marlin/example_configurations/Creality/CR-8
Note that you may have to use the rest of the code from the same branch as well.

[willysmoose59]

@D-side Thanks for the info. I see the corrected information in the fix files but the board listed is not in the boards.h file. Is there an updated boards.h out there with the correct info?
