V-Core 3.1 commissioning
I’m in the process of commissioning my V-Core 3.1- 400, I have an acceptable bed mesh and a serviceable first layer calibration.
I’m currently in the process for sorting out the parts cooling fan. The issues I’m having with the fan is as follows:
When I first powered up the printer the Fan would energize at 100% on startup despite the console indicating it was at 0%.
By sliding the percentage to 100% the fan would turn off. (How do I fix this?)
After several firmware restarts while adjusting various other printer components the fan stopped working all together, I believe it’s possibly toast.
I have ordered a new fan but I would like to continue trouble shooting the issue, I have the jumper set to 12v for the red and black wires and the blue wire jumper is set to 24v. I have not changed any parameters in the config file in regards to the cooling fan. I have a 12v 4010 fan I would like to temporarily use to bench test on the printer MCU configuration before I dig into the tool head wire loom and permanently install a new 4028. (Any recommendations would be greatly appreciated)
I’m running an BTT Octopus V1.1 MCU.

I just did, I got the fan back on, it was a bad wire. I also sorted out the 0-100 issue. Now the parts cooling fan kicks on during a print at 100% and cools down the hot end causing kipper to shut down. The hot end heater cannot overcome the cooling from the parts cooling fan.
What do you have the fan percentage set to in your slicer?
Not sure I did not look for a fan setting in PSLICER.
I will look into it and revert back, thanks!
You need to tune your fan settings to match your hardware and what you are printing
Will do, this is my first Klipper machine, I have a PRUSA but this definitely a steep learning curve. I’m thinking the 4028 server fan is overkill for my setup considering its cooling capabilities overpowers the hot end. Would it be better to run a smaller fan or is it better to run the 4028 and a lower load?
Ok looks like the fan settings in the PSlicer is the issue. MIN and MAX was defaulted to 100/100, fairly confident I will get this sorted but that will have to wait until Monday.
The 4028 fan is fine. You have to tune your slicer profile like normal
Appreciate the feedback.
Progress, the one on the right is with the adjusted fan settings!
