Reducing PLA Jams
1) Set temperature at 205C. Now, there could be a lower temperature at the nozzle, but the additional 15C above PLA rated temperature leaves a lot of room for preventing a cold jam.
2) First tried setting the PID_MAX to 150, got jams. Set it to 200, got wildly varying temperature around setpoint. Set to 175 and go a reasonable response. Your mileage can vary, but PID_MAX value will contribute in a better sense that PID autotune.
3) Use sunflower oil to season the stainless steel heat sink. Used a syringe and needle to drop a few drops of oil into the heat break before every print, then let 10cm of PLA just flush the excess oil. I cannot believe how less a force is required to extruder 1.75 mm filament through a 0.4mm nozzle, after what I have dealt with in the recent past.
4) aligned the filament straight into and out of the extruder motor.

Result. A 6 hour long print, no jams, completely unattended during this time.

+Makers Asylum  Need some advice. I saw the elephant printed when I had been there once. I tried it today, but the joints have jammed. Can you suggest what are the best settings to slice it?

+OctoPrint  Ported the Octoprint from the Raspberry PI instructions to the humble TP-link MR3020 Wireless router running OpenWRT. Had a few hiccups in the process, but totally satisfying project.

updated the instructions on my blog. Performance (in terms of latency) is at par with my laptop. Need to run a long print to verify any bottleneck, but so far its been amazing.
