multiple processes: extruder temperature ignored

Fri Dec 26, 2014 7:18 am

I try to optimize the extruder temperature for a certain type of filament. To do this i created a simple zylindrical object and want to vary the extruder temperature every 5mm in z height. I created processes with different temperatures and ranges of layers. But only the temperature of the first process is used. There is no other M104 (or M109) statement within the gcode. Same effect with heat bed temperature.
Changing other parameters work well. I use multiple processes quite often; that's a very useful feature!

I have the same issue. I set the bed temperate lower for the layers other than the first layer but only the first layer temperature is used.

My printer is the DaVinci 1.

this is a general Issue.

you can workaround it for some cases with temp. setpoints e.g. for the last layer in the prior profile...

Sequential printing problem:
I am also having trouble when trying to work around this problem.
Process1: 1:st layer 235, last layer 240
Process2: 1:st layer 240, last layer 245
Process3: 1:st layer 245, last layer 250

Process1 works fine, temp starts at 235 then changes to 240 for the last layer, but then trouble begins:
Process2, temp is set to 240 but heater decends to 235 before getting up to 240 sometime after the print already has started. Last layer prints at 245.
Process3, temp is set to 245 but heater decends to 235 before getting up to 245 sometime after the print already has started. Etc.

What am I missing here?

It works fine for me. Perhaps you setup your temperatures incorrectly.

Post your factory file and I'll take a look (file > save factory file)
