Using smaller layer heights will increase time significantly (since the max flowrate is not being reached) and Rana has not tested them. Using the 0.75mm layer height setting may perhaps save about 15-35% time for certain objects. | ||

* BL-touch flashing red? it is because the little stick at the bottom is not actuating properly because it is being stuck for some reason. To resolve, gently use your finger to pull the stick down and push it back up. Restart the printer, upon start up the BL-touch should go up and down as its start-up test | |||

* | * Octoprint is set up. Can also use the USB stick on the side of the touch screen, however for very large gcode files (>3MB?) there can be lag in sending gcode commands to the printer which causes stalling and gaps in the extrustion. For large gcode files use the micro-SD card that is sticking out of the power supply, or use octoprint. | ||

Once the filament has cleared the fitting, insert it into the tubing and re-insert the tubing into the gold fitting. MAKE SURE the tubing is firmly in the fitting or else it will get pulled out and mess up filament feeding. | **If all else fail then can remove the tube from the fitting by pushing down on the blue collar and pulling the tubing up.

=== Extruder tension for TPU / flexible filaments === | |||
For regular hard plastics, the tensioning knob should be well on with the screw protruding from the knob 2-3mm | |||
For TPU or flexible filaments, it needs to be MORE LOOSE or else the filament could jut out from the space below the extruder gear and above the teflon tube that goes into the heatbreak. It looks pretty funny when the filament shoots out, the filament wants to be free!!!! The knob should be past the screw, with 1-2mm of the knob threads off the screw, it'll look something like this: | |||

*a 0.4mm nozzle will take five extrusion lines to draw 2mm of perimeter, whereas the 1mm nozzle can do it in two lines. 2mm perimeters are pretty freaking strong, you can get away with like infill at 10% or 15% (some people do 5% lol) because most of the strength comes from the perimeters.

**Note: the TMC stepper drivers on the board usually have stealthchop enabled (for silent stepping), however stealthchop fails at speeds above 100mm/s. So for fast travel moves the firmware will switch the stepper drivers to spread cycle mode. So the printer will be louder on fast travel moves. | |||

Keep in mind that this printer has a 1mm nozzle installed | Keep in mind that this printer has a 1mm nozzle installed. So for an object with 1 perimeter is the equivalent of 2.5 perimeters with a 0.4 nozzle (so decently strong). So for most objects 2 perimeters and 4 top/bottom layers is plenty of plastic and will be strong enough. This will save a shitload of time!! | ||
