Cura 4.6.1 - "Printing temperature initial layer" not working

[merin_83 0]

Hi, Am not able to get the "Printing temperature initial layer" working. I need to have a higher 1st layer like 205 for PLA and after that print at 195. But Cura seems to omit the "Printing temperature initial layer" setting. It just starts printing at 195. Please let me know what the issue is ..

Looking at that you have a error with the “initial printing temperature” setting, this setting needs to match or be lower than the “printing temperature” setting. This setting tells the printer at what temperature the printer can start printing from as it gets up to the main printing temperature.
 

So it your case set “Initial printing temperature” to 195c and the printer will heat up the hotend to 195c and then start the first layer as heating up to your 205c setting then after the first layer it cool back down to your main printing temperature of 195c you have set.

An option would be to set the printing temperature in Cura to 205.  In your Gcode file at the start of the second layer (layer:1) manually add M104 S195.  Layer 0 would print at 205, the M104 line would be read, and printing would be uninterrupted as the temp fell to 195 for the rest of the layers.

There is the "Insert at Layer Change" plugin.  You could use that set to "After" and Gcode to M104 S195.  The M104 line would be inserted after every layer.  Layer 0 would print at 205 and the rest would print at 195.  However, if you needed to tune the temperature for some reason it would revert to 195 at the end of every layer.

Thank you, actually i was asking about "Printing temperature initial layer" I saw in some posts that “Initial printing temperature” was only if we have a dual print head.

thank you, let me try that plugin ! I need this to get a good bed adhesion and the after initial layer, print litle less temp for bridging advantage.
