Topic: Layers get separated

I am printing some hollow objects with a wall thickness of 1.2mm and sometimes the layers get separated with a slight pressure. Is this normal? I am using Octave ABS filament and extruder temperature of 200C and 0.3mm profile. I already tried with and without extruder fan upgrade.

Thank you in advance for your help,

CB

As a matter of facts it happens with black, orange, gray, red and white. I haven't tried the rest.

Re: Layers get separated

Is it safe to set the extruder to 205C or more? I got a reply from Octave support and they recommended to set up the temp higher.

In fuller detail for anyone else ever reading; Solidoodle reported temps are about 30°C *below* the highest temp in your heater core. So this is why people use 190°C to print ABS that normally requires 220°C.

The item that suffers the most in high temps is the PEEK holder section - It has a failure tempreature of 250°C. Knocking 10°C off this for 'safety' and to deal with overshoot, you can run the Solidoodle at temps up to 210°C without problems, but I would not exceed this temp as you then are well approaching the PEEK failure temp.

Nutshell version - 205°C is ok, but I wouldn't push past this. And thats already 235°C 'actual', so I wouldn't expect the filament to need more than this anyway if its within standard parameters.
