QIDI 1 surging fan

[JensC]

You said there are hot end fan speed settings in Simplify3D. This I know. They do not, however, apply to the turbo fan. It's either on or off. The hot end fans run fine making it unlikely to be a PS issue.

I don't see where I specified hot end anyways but here is a screen shot where you can adjust the settings of the AUX fan.
As you see here I have it at two different speeds, one for the first layer and another for the rest. You can make it do more as you see with the settings.

Unfortunately, the QiDi printer does not respond to the fan/blower/aux speed setting other than to be either on or off. S3D does allow one to set the "fan speed" by layer, but my understanding is that there is no compatible "X3G" command to set the fan speed, so the QiDi just turns the fan on full, or off as a compromise.

Always works for me. I send the gcode over via my OctoPi.
I know though you are correct on x3g files via the SD card it does not work. If you check the box in S3D (it may be on by default) it saves both the x3g and gcode.

Reality Check (back to the thread topic)

1. Answer to my first original question:

The aux cooling fan plug near the extruders was defective. At rest it worked but when jerked around by the head in certain directions the fan power was intermittent. Fixed.

2. Answer to my second original question:

The code to turn on the aux cooling fan is M106. The code to turn it off is M106 S0.

No need to be rude.

Educate yourself.

Glad you found the issue with the fan.

For the fan issue in the file itself as I stated and posted a screen shot for you, Simply 3D allows you to control the fan speed layer by layer of you want.
I setup OctoPrint on an RPi (hence the name OctoPi) and send my files to be printed directly to the printer through that instead of the SD card route.
It does not like the x3g files and instead uses the gcode files. S3D has the ability to save both the x3g and the gcode file at the same time.
Fan on/off and speed settings work on the gcode file. The x3g its either on or off. I've not looked into seeing if you can pack the speed control in the x3g file.

Glad your up and running again. Enjoy.

Fan speed was irrelevant to my original thread question. Its inapplicable as the QIDI printer has no variable speed fans.

"Educate yourself"?!... "No need to be rude"?... Hey, Pot.... meet Kettle.

Jesus, Mary an' feckin' Joseph. Honestly.....

Time for everybody to just back away from this one...
