Partially Solved Stringing or Oozing

PLA or ABS?
Neither. Use one of the other DOZEN filament types and then decide which is better for you

P.S. Yes with PLA stringing is normally printing too hot.

 

Poll cannot be answered since it is asking a nonsensical question. But ABS is one of the worst to print with. It was never designed to be an extrusion and has properties better suited to injection molding. People still use it and since it is the LEGO plastic they think everything should be in ABS. There are so many other filament chemistry's now that far exceed some or all of the properties of ABS.

@mark tomlinson is right about PLA being too hot and stringing. Most filaments behave the same way except PETG where stringing usually indicates extruding too cold.

 

It is generated when the firmware thinks your extruder is too cold.
There was at least one version of the R1 firmware where this number was set to a really silly temperature of (IIRC) 185 to 190c
As long as it kept printing you are fine, but you might want to sanity check that you have the current firmware for your printer and I would suggest you start with being very certain you know exactly which model you have.

 

Only for the C2

 

@Rigmarol the only better firmware for the R1 Beta | R1 | R1+PLUS is the Marlin 1.1.0 that I posted in the mods sub-forum. It has so many things fixed that that did not work as expected in the firmware originally provided by Robo (not the fault of Robo but rather Marlin 1.0.0 upon which it was based on). Robo has never released a version of the firmware for the R1 Beta | R1 | R1+PLUS that is newer than Marlin 1.0.0 regardless what they call it.

The only real issue (really a non-issue) you will have moving from Robo (Marlin 1.0.0) firmware to the Marlin 1.1.0 firmware properly configured for the Robo is that you will likely need to tweak some of your slicer profiles to correct workarounds done using Robo's original configuration.

Don't take my word for this, just ask anyone currently using the community supplied Marlin 1.1.0 firmware.

 

And that branch @WheresWaldo maintains is slightly ahead of the C2* in terms of features/functionality.



*it is fine for the R series, I would not suggest use on the C2 since there are a few minor tweaks in the C2 version that are specific to it.

 

Without owning a C2/R2 I cannot just guess what Robo has done with Marlin firmware. If I ever decide to move from my R1 to another Robo 3D printer then I would probably make sure it was current with Marlin development.

@Rigmarol You did ask if there was anything newer.
@mark tomlinson The tweaks to the C2 firmware are minor in my cursory investigation, but I can't test anything so I won't be playing with the firmware for it.

 

Until they decide to check back in their changes it would be a major pain. Someone would need to diff/merge their stuff back into the current branch ... ugh. Not even worth doing until post-R2 release in case there is anything else that needs changing. I can't see much future in the maintenance of their custom stuff anyway, the users will likely want to go into mainstream Marlin by the production label at any rate. I may well jump in and help out with that merge once they are totally stable.
