RE: Prusa mini Fysetc clone - log of a journey

Thank you so much @turro75! 

Can you please compile the new firmware and increase the max bead temperature to 110 degrees Celsius.

RE: Prusa mini Fysetc clone - log of a journey

Hi,

this is written in the Configuration_MINI.h:

// Beware: this is the absolute temperature limit.
// The MINI cannot normally reach 110C.
// Thus all usage in the UI must be lowered by 10C to offer a valid temperature limit.
// Those 10C are a safety margin used throughout the whole Marlin code
// (without a proper #define though :( )
#define BED_MAXTEMP 110
#define BED_MAXTEMP_SAFETY_MARGIN 10

 it is enough set to 120 the BED_MAXTEMP, are You sure?

RE: Prusa mini Fysetc clone - log of a journey

I am aware of what Prusa said with the 100C limit, but I have tried running it at 110C withthe LLama mini firmware. The printer takes some time to reach 110C but it will do it. Especially if it is in an enclosure. 

I would be really thankful if you could increase the limit so that 110C can be sett. I am aware of the potential dangers associated with running the bead at 110C 

 

thanks and greetings from Austria 

Tim

RE:

Ok,

here You are the latest 5.1.2 with the listed mods

  1. extended x-axis length from 188 to 195mm as on my clone selftest failed due to that
  2. enabled PID autotune (M303 working for hotend and bed)
  3. enabled skew correction (M852)
  4. disabled screen flashing every 2secs
  5. set the hotend thermistor type to 1 instead of 5   
  6. increased the hotend fan speed from <3000rpm to 4500rpm
  7. increased the heatbed max temp to 110°c
  8. increased the hotend max temp to 280°c

in the archive and below there is also the patch file for the curious about which are the changes against vanilla code

RE: Prusa mini Fysetc clone - log of a journey

Had anyone thought about editing the x-axis plastic parts to shorten the x-axis?

RE: Prusa mini Fysetc clone - log of a journey

@turro75, have you looked at 6.0.0 yet? I just tried flashing it on one of my Fysetc clones and the screen is back to flashing white and then redrawing every few seconds. I'm going to revert back to previous firmware.

RE:

I've built it. Thanks to Turro75 for doing the work and sharing the patch (a true spirit of free software!)

 

There are a few corners cut:

- I omitted the skew correction (M852) code (because patch failed to immediately apply and I didn't use M852 anyway),

- I didn't care about language builds (because my lang is unsupported and I use English).

Included: the patch file and the `bbf` firmware. And you better be updating from v5 at least because I didn't test it with anything else:  Fysetc_clone_v6.0.0

**You may download the file ↑, flash it, and stop reading here**

---

Anyway, that's how I built it. I use macOS latest with `homebrew` installed, if that matters. But that should work the same in a modern Linux as well. Windows folks, you figure it out yourselves ;).

Clone the repo:

```
git clone https://github.com/prusa3d/Prusa-Firmware-Buddy.git && cd Prusa-Firmware-Buddy
```

Checkout the v6:

```
git checkout v6.0.0
```

Apply the patch:

```
patch -p1 <~/Downloads/.../Fysetc_clone_v6.0.0.patch
```

(Practically, you type `patch -p1 <`, then you drag the patch file to the terminal window). If you applied my smaller patch, you should be good. If you applied the original, you should now deal with rejects and finish the patching manually.

Next, create a `venv`:
```
python -m venv .venv
```

Now you should've be able to build the code with:

```
python utils/build.py --preset mini
```

**But,** one pesky check will fail (check_git_repo_for_dangerous_remotes).  It requires you to have a remote, but it should be disconnected from Prusa's repo. Let's fix it with a kludge:

```
git remote remove origin && git remote add origin git.invalid/foo.git
```

Now, run the build command again and you'll get a message telling you where the `bbf` files are place after a successful build.

RE: Prusa mini Fysetc clone - log of a journey

Weird. I can't edit my post, so here it is attached one more time: Fysetc_clone_v6.0.0

In case it won't work _again_ , I've uploaded it to box.com: https://app.box.com/s/n95pyyef98qo9sxi537fh9ybu22199ys
