I have gone through z axis set up many times, bed leveling.

Prints come out very nice if positioned on the edge of the bed. Larger prints or printing in center the bed actually lowers and the filament doesn't stick.

I use Cura to slice and also sliced on board the Robo 2, same result.

I've replaced the bed surface, but clearly the z axis lowers during print.

Either way, it seems like these cables and the connector are not rated correctly.

Bed heating on v2 of R2]]> 33 Wed, 11 Dec 2024 15:23:29 +0000 http://community.robo3d.com/index.php?threads/g36-failure.25026/ http://community.robo3d.com/index.php?threads/g36-failure.25026/ invalid@example.com (Colin) Colin
I have had 2 recent (as of Monday) successful prints, the last one taking up the whole print bed, and I may have been a bit violent taking the print off (I don't know why this would cause the issue, but putting it in here for posterity). After this, each print I have tried has failed during startup, and I have...

Just checked and all of the gears seem tight, they're just friction fit with the set screws on the rods, correct? I did notice one of the sliders looks like it's separated at the snap-together underneath, but everything still seems to be sliding smoothly (not sure where i'd get a replacement anyway).

Any suggestions? Trying to reduce speed and see if I can make it through the current items to print,...

I have tried on a W11 machine and W10 machine same issue, there is a %appdata% folder that is empty.

Additionally when trying to connect to my R2 for Cura 5.0 it states that it isnt able.

Is there any way to modify this? There is a stage where it's waiting for the bed to heat and holding the hotend at purge temperatures, just oozing garbage and not extruding to compensate, leaving a blob and thin extrusion both at the start of prints. So far it has only...

I followed the black screen troubleshooting post and got nowhere. What I see now on the screen is a prompt for login info (see file).

I tried writing to robo a week ago with no communication back. I'm assuming I need new SD cards? Any other things I can do as this is really affecting productivity

Thanks
