Nozzle temperature going down while extruding
October 29, 2010 11:43AM
Hello,

my Mendel is somewhat able to extrude a bit of PLA but the software (both Adrian's host and RepSnapper) report that the temperature is going down after a while. Naturally, the PLA stops to flow down the nozzle.

Please, have anyone seen something like this?

Yes. It's been reported. Last time the cause was that the G-code contains the temperature specifications, so if you generate G-code, decide that the setting you had wasn't high enough, and try to print again without regenerating the g-code, you get this. The host warms the extruder to the spec'd tempurature, and then the gcode starts to print fine, until the temperature setting gcode is sent out and the nozzle cools down again.

Solution is simple: regenerate the g-code if you change the tempurature.

You are right, the g-code contained wrong temperature code.

It works!
