Re: Heating extruder only on printing moves

You want pins_RAMBO.h, or a MUCH newer version of the firmware than you're using.

Your "no thermistor" and "dangerous moves" will probably be fine.

Re: Heating extruder only on printing moves

You might be able to use Marlin's "DISABLE_E" configuration option, which will disable the stepper driver immediately when it's not being used. You can then swap the E0_ENABLE and HEATER_0_PIN numbers in pins_RAMBO.h. Make sure your TEMP_SENSOR_0 is 999, and TEMP_SENSOR_BED set to 998, and DUMMY_TH...

Re: Linear Mode Power Supply

Use your other option. There are 3 sets of wires going into RAMBo's power supply -- the top set (nearest the blue fuse) are -/+ heater, then the next two are -/+ heaters/logic, and the last two are -/+ for the motors. Remove the middle two wires and use your own linear supply. That said, I'm on Ed's...

Re: Extruder now moving left too far - making grinding sound

Did you use the new endstop flag? There's a piece that holds the belt in place, that's a different shape for the dual.

Re: esun epa jamming up the drive

Both of those are moisture. You need to bake the filament in a dehydrator for several hours before you use it, and load-and-start it while the filament is still warm. PA sucks compared to normal filaments you're used to.

Re: esun epa jamming up the drive

Less drive tension -- if you over-squish the filament trying to dig into it, you'll squeeze it into an oval and it will jam. Less tension and go slower :)

Re: Any Print Settings Tips for CoPolyester?

You probably don't want to hear it -- but PETs really like wider nozzles.

Go slow, hot, under extrude slightly (I run 0.93), 250C nozzle, 75C bed with hairspray.
