Unresolved Printing with a SD-card

I pull the plug since some programs will fire off a stop command when you exit/disconnect.

 

Regardless of what the computer operating system tells you the file must be named that way or it will NOT autoprint.

I also never used the integrated SD card reader for the RAMPS, rather all of mine have an LCD controller (which has an SD card reader on it) and those work without the need for a computer.

Maybe someone else has used the stock reader this way and can add some hints, but you must have it named correctly for starters. That is not optional. The firmware is looking for that specific filename: auto0.g
No other name will work.

 

I believe if you start hooked up you must stay hooked up. According to the robo firmware page you move you axis away from the home switches pop in your sd card and tap the x home button once and it should start. Thats disconnected from your computer all togather start to finish

Thats assuming you have a robo r1+ with the new firmware (v2)

 

Tgere should ve a button that says disengage servos(or motors) or release or something of the sort that lets you move the bed and extruder with your hands. Then put the extruder in the middle and pull the bed towards the robo lettering. Then if you have the gcode saved as they instructed and click the x endstop (switch on the left) it should start printing. I havnt tried it just relaying their instructions. I have an lcd controller and i print with that

 

I believe your stl file that geta put on the sd card needs to be named robo.gcode or however they put it in those instructions i linked. hang in there buddy im confused to as never having done it. Its totally new with the new firmware. Give it a shot and lets see what happens

 

When you export to save the g code to the sd card you should be able to name it what you want. The printer is very good in my opinion. All printers have a huge learning cypress. Honestly I'd pick up a lcd controller buddy. It's top 5 best things I've done to my robo.

Save g code anyway you want to ad card. Put the card in the controller...scroll to print from sad click the file and off to the awesome.

 

Please note that Robo never removed the ability to execute and print automatically a file called auto0.gcode. This has been built into the Marlin firmware. They did add, rather crudely, the ability to auto execute robo0.gcode. It is meant to start printing as soon as the printer is powered up and recognizes the SD card. If you have an LCD controller, whether a Full Graphics or not you can actually print any gcode file regardless of how it is named, directly from the menus. Why make it harder on yourself than it needs to be. If all you want to do is start a print from the SD card, get a controller, either cheap direct from China or from Amazon in N.A. or from any of the vendors that frequent this forum. It will be infinitely easier than trying to do all this automatic printing.

There is not one single person on this forum that has ever regretted buying an LCD controller and most that have one will tell you it should be one of the first, if not the number one, accessory to buy (even before more filament).

 

@fredm My suggestion is not to upgrade to V2, there is no need and Robo added code that was not clean. It does not add any additional functionality to your Robo as it is still the very same Marlin 1.0.0.

I am sure people like @daniel871 will concur.

There is no need to change firmware for LCD controllers. The 2004 and XXL (same controller except for actual LCD size) needs no changes to firmware. The Full Graphics controller just needs a two line change to the source, a recompile and reupload to make work. There are literally 10's of posts that explain the procedure on this forum.

 

If you insist on trying to get automatically started printing to work then you have to understand how Windows works and the SD card within Marlin.

Here are some simple steps (not inclusive) using Windows 10 as a base.

1. Open File Explorer
2. Select View and make sure you are on Details in the Layout section
3. Also in the View menu select the checkbox that says File Name Extensions in the Show/hide section

Now you will be able to see and manipulate the filename and actually see what you are doing and not guessing

1. Save your gcode file from your preferred slicer
2. Navigate in File Explorer to the directory you saved the file to
3. Rename it auto0.gcode
   Make sure it is only auto0.gcode, all lowercase
4. Copy the file to your SD card.
5. Disconnect your printer from your PC then insert the SD card

It should autostart printing as soon as the SD card is recognized, you might have to power cycle your printer if it doesn't start up automatically.

To be honest this is simply too much work to do on any type of regular basis and was not intended by the Marlin developers to be a regularly used feature. But if you insist.

Yes the XXL is plug and play

 

I think if it were me at this point id put in a parts request for a new card reader. If you plan on switching to a controller youll be ditching that anyway.
