Topic: New temperatures

So im pretty sure the temp in my extruder is the reason for my constant jamming.  Im in rep host now.  Anyone lower the temp there?  I wonder why the doodle runs at 250c  I typically run my solidoodle 2 at 200c for abs.  Any thoughts?

Re: New temperatures

Press measures heater temperature.
SD2/3/4 measures nozzle temperature.

Nozzle temp != heater temp.

Re: New temperatures

Nozzle temp != heater temp.  I don't quite follow.  Also on a side note do you work with E3d and filastruder?

The heater is the heating element that heats up the nozzle.  The heater itself will always be hotter than the nozzle.

It's like measure a stove coil temperature versus the temperature inside the pot sitting on the stove coil.  They're different.

He is Filastruder and Filastruder is a distributor of the E3d.

Oh yeah? I rock a few e3ds I got from filastruder.

Re: New temperatures

I understand.  But as far as I can see the thermistor is still in the heating block in a hole right next to the cartridge heater with a much much smaller nozzle.  It doesent seem like that would differ 50c between designs.  But aside from that has anyone tried lowering the temp?

I had all kinds of extrusion problems at first, had temps too high.  Filament was stringing, not sticking, and clogging.  I lowered my printing temp to 242, and bed to 85.  My prints are great now, it has a lot to do with it.

The thermistors are different and so give different temps, I sometimes use a SD thermistor with my E3D and so I need to reset the firmware & run autotune, I find it particularly difficult  helping other members because to the temp differences. In any case my temps run between 230C to 238C for ABS using a E3D V6 . I got hung up with bed temps I started at 80C with great results, but now I'm running at 105C the only difference I see is it's been raining in my area almost every night so maybe moisture may be any issue.

Re: New temperatures

Soliprint 1.1 sets ABS to run at 215!   Has anyone run this low on their press?  How did it go?

Re: New temperatures

Could be a different calibration curve on the thermistor. They could have done that to make "temperatures" more in line with previous "temperatures".

Re: New temperatures

Wouldn't that require some sort of firmware update?

I tried a print at 215... Didn't stick to the bed so well.

Re: New temperatures

Nope, just remap it in software.

Firmware sends "250C", display "215C" in software, etc.

Couldn't set the second line without picking up the first line. No chance getting an initial layer down. I will not being using these setting in the future.
This must be Solidoodle's software team trying to fix the internal bending/jamming of filament just above hot end..
