Hello,
in CP6 when printing on K1Max in the filament settings Generic PETG-CF I change side fan from default 0% to 40%. I chose no cooling for first 8 layers. But when the 9th layer is reached the side fan doesn’t turn on. When you have no side fan extruder gets overheated what will lead to filament stuck and jam.
Please fix this!
Could you provide the 3MF file at that time? Does the side fan refer to the additional-cooling- fan?
File will come in the next days. Well it’s the fan on the right side of the printer when you stand in front of it.
After the print test, the setting of the auxiliary fan was effective. It turned on the fan after specifying the Z height,you can first confirm the firmware version of your machine or check if there are any issues with the auxiliary fan’s wiring
Did you start with the ‘Generic PETG-CF’ profile and modified that, because this profile has 0% fan as default and then on the top of the settings change “no cooling for the first … layers” to a higher value like 10? Has your model overhangs that need support, when I know it right there will be added additional layers for the support, maybe has something to do with that?
Will check the next days and come back then, thx.
Checked it now. Tested it with the benchy model and it worked, fan turned on. But then tested it with my model, there the fan did not turn on.
Still trouble with the fans, it’s the model fan and the side fan. Both don’t turn on reliable when no cooling for 24 layers is set. Don’t know what I can do? You mentioned check the wireing. Can you tell me which wires should be checked?
I think it has something to do with the calculation of the layer height when ‘variable layer height’ is used to prepare the model in CP6. Also ‘independent support layer height’ might influence the calculation.
As an example I used ‘no cooling for 24 Layers’ and in the preview the 24th Layer has a Z-value of 2.8mm. In the G-Code
M106 P2 S76
;LAYER_CHANGE
;Z:5.14141
;HEIGHT 0.202918
So when you calculate 5.1414 / 0,2 = 25 Layer. The calculation is based on a layer height of 0,2mm. But it doesn’t match the values of the preview.
Please fix this so that for the last layer a user wants to have for no cooling the number can be taken from the preview and then can be set in the filament settings for no cooling. Or maybe you can make a calculation in the filament settings when a user entered a number of layers, and say this means layer x layerheight. Then the z-Value can be compared with the preview.
