Topic: repetere and using the stock fan control for cooling

Hi,

I have a separate power supply for the extruder fan, so I decided to flash my Da vinci 1.0 with repetere with the option to use stock fan control for cooling. So now I was trying to print with ABS (did not want any cooling) and using Simplify 3d I went to the cooling section, set 1 layer to 0 and disabled all other cooling options but when I start printing from the file saved to the SD card it still throttles up the cooling fan. Why? What am I doing wrong?

Re: repetere and using the stock fan control for cooling

if you're using separate power supply for the fan, you cannot control it via simplify3d.. it's just on/off

You misunderstood me, I was just saying that I have an independent power supply for the extruder fan. I'am trying to use the stock cooling fan as layer cooling fan, so it is plugged into the pcb board.

I have a similar set up.

I just want the fan cooling during bridging. So in slicer in the cooling section I just change the values to 0 for fan speed. Bridge has its own speed which I have set to 100

Re: repetere and using the stock fan control for cooling

When you flashed repetier, did you configure the fan for gcode control as per the guide .....
"To repurpose the main Extruder cooling fan to be controlled VIA G-Code instructions M106/M107:
Set REPURPOSE_FAN_TO_COOL_EXTRUSIONS to 1"

I did. I also know that it worked (at least in firmware) because the fan does not switch on before extruder starts to print (previously it started to work as soon as the extruder was heating up). For some reasons though, when I set in simplify3d an instruction, not to use cooling fan, it still comes on.

You could always put an M107 command in your startup script. That should turn the fan off.
Check your gcode for any M106 commands (fan on) after the startup script, if you don't see any, you know it's not something to do with Simplify3d and the gcode.
