UPDATE: The fan that I installed was bad. Problem solved! Watch out for what you buy on Amazon!

@jens55 My other 24v fan that I tried was working fine. I’m pretty sure that the blower fans I bought might be faulty. I’ll try plugging it in place of the working fan as soon as I get the time. Thanks for the advice!

@mrehorstdmd I have not been able to hook the fan up to a power supply. I am starting to suspect that my fans are faulty. I got them in a pack of 4 from Amazon, so I will definitely try to hook it up to a power supply to see if they work. (When I get the time of course)

Hello,

I recently converted my printer from a 12 volt power supply to a 24 volt power supply. Everything seems to be working EXCEPT my part cooling fan. I replaced the old 12 volt one with a 24 volt fan. When I use the slider in web control, the fan does nothing. I have checked my wiring, and there's no problem there. Really not sure why it isn't working. I'm running a Duet 2 Wifi on firmware version 2.03. My config file is attached for reference. Feel free to add any other suggestions. Thanks!

I still have my stretched benchy

To summarize, I set my Z steps per mm to 400.

I know that this is a bit redundant, but I reset my steps per millimeter to 400, and this time, I've finally got it. I would like to thank you all in this thread for making my printer the best it can be. And so, thank you all again for the amount of help you've given me.

Very interesting. Despite the fact of me figuring out my problem for the most part, My prints are appearing to be very stretched in the Z direction. I might want to consider changing it to a TR8x8. Thanks for the help.

Upon testing, I now have the right heights in mm. Thanks for the help!

Here's the bare bones kit I'm using in case it helps.

I just did the calculations, and I multiplied the pitch of an M8 (1.25) by how many starts my screw has (4), and I got 5. I put that into the Prusia calculator, and my steps per mm are now 640. I think I've finally got it right. I'm testing my new value by printing a benchy.

I looked up my printer's specs, and I have a 4 start acme threaded leadscrew. So then what would I have to change in my calculations?

I've changed the value, and the Z-Axis seems to be more accurate, but I'll still have to print to see if anything has changed. Thanks for the help.

I'll check to see if my screw is M8. If it is, then I've been using the wrong settings this whole time.

Hi,
I'm already aware that my Z-Axis probably has the wrong steps per mm, as my Z-Axis is in centimeters. As far as how my Z-Axis is setup, I have an M6 lead-screw driven by a Nema 17 stepper motor at 1.8 degree step angle. And if necessary, here is my config.g file.

@Phaedrux
I took your suggestions into account as far as speed goes. I added a zero to the values that I thought could go faster, and my machine is now running at an even better pace. However, I had to reduce the acceleration and speed values of my extruder, as it was moving to fast, and it never properly gripped the filament. I'm still testing things as far as it goes, but so far, things are moving better.

Update:

My mesh bed probing is moving at a much more desirable speed, thanks!

And if anyone is wondering, I'm using a Printrbot Simple Pro bare-bones kit, so if you have any suggestions, feel free to tell me.

My Z-axis has been running fine, but I'll consider changing that if I see too it. Thanks for the concern.

Thanks, I'll try that now.
