Specify Bed Temp First Layer Only
Posted: 18 Jan 2015, 11:39
What gcode allows me to specify the bed temp higher for the first layer than the other layers?
Kisslicer generates the Gcode. So you want to edit the Gcode after Kisslicer has generated it and before you send it to the printer?
M140 Snnn ; nnn is the temperature you want. This will set the temperature until the next M140 Snnn is seen.
Thus you need to find in the Gcode where it starts the next layer and insert your M140. You can do this as often as you like in the file.
I suspect though your question was "How do I set in Kisslicer a specific first layer termperature". For this you go to the Material tab, and set the bed temperature for the 1st layer. Then go to the Printer Gcode tab, and select the N*layer. Enter the M140 Snnn code for your other layer temperature. Change the "every N layer entry to 1". Kisslicer will now insert that piece of code in every layer (somewhat reduantantly after the 2nd layer ... but no harm)
In general though, my experienece is that changing bed temperature is a bad thing .. cooling to early risks it detaches.
