Thanks for sharing.  Box Turtle in on the radar screen.  What is your opinion of it?

In my opininion by far the most reliable of the different MMU's I have build. At the point now where it is slicing a print and walking away knowing it will complete. I have just finished building the HTLF from armored turtle - easy and cheap but needs a spool rewinder like filamentalist.

Box Turtle Pro's:

  • Reliable
  • Spool rewinders built into unit
  • Excellent build manual
  • Great Discord support
  • Enclosure with filament heated box.
  • Reliable and actively developed AFC-Klipper Add on software
  • Mainsail integration
  • When unit pauses , the mainsail UI will outline the steps to recover from the pause

Box Turtle Con's:

  • Expensive, especially with the enclosure
  • Requires a toolhead cutter for 100% reliability 
  • (This was where I had most of my problems with the unit pausing during a print. I am using the FilamAtrix repo for the cutter for the Stealthburner. However the Micron has a Rapidburner - in the process of converting this to utilise the HTLF unit. There is a cutter available on pritables which I will try.)

As for the klipperscreen integration - Great. On discord there was a Turtlescreen project which I implemented, however a recent update to the AFC software broke it's functionality. This klipperscreen add on therefor is a great addition. My printers are all in the garage, thus easier controlling them from klipperscreen

Turtlescreen: (No longer functional untill the developer updates the Turtlescreen firmware to be compatible with the latest AFC.

Summary and pics very much appreciated.  As I remember you were able to get an ERCF working; so your thumbs up on the Box Turtle means a lot.  To do over, would you self source the Box Turtle or go with a kit?

Filametrix - what source did you use for the blades and  how well have the blades been holding up?

Are you planning to build a tool changer machine? Mixing some filament types is not a good fit for Box Turtle. I saw an interesting video printing a bellows in TPU which used PLA for support.

Does Box Turtle require CAN bus? My 2.4 is using the cable chain setup with Hartk Stealthburner 2 Piece tool head board.  I've heard CAN bus can take a bit of work to get the drivers installed and setup up.  Would the NiteHawk USB be an equally viable option?  I've heard the USB just works.

That question is now loaded. Since the introduction of tariffs by the USA on Imports from foreign countries - I understand that the cost of components have trippled in price. Self sourcing in my case was half the price of the LDO kit, and honestly I cannot tell the difference in the operation of either unit.

I am currently using these from Fysetc (Aliepress) as they are already cut down to size. Has not had to replace a blade as yet. On the two printers that had the ERCF and Tradrack, I used these from Aliexpress, but they needed to be cut to size. Again no issues. In saying this I mostly print ABS or ASA. I understand PLA is a bit tougher to cut and cannot say how they will hold up there.

I once had a look at a Tridex, but did not persue that. There is one that interest me, Lineux,  and I may consider this on a planned Ender5 Plus conversion that is gatering dust (and quite a bit of it). Originally looked at this for the VZBot. Although I just finished building a HLTF unit with filamentalist v3 spool rewinders. (What can I say - I like building things). Still need to apply for a serial - because that's what one does! 🤣

Don't know where this is going to go but it is built. 🙂

The AFC-Lite board has either Can or USB. If you have a cartographer probe, it is recommended to use it in USB mode as Canbus mode fries the probe. (I believe this will be rectified on the latest release) You can also use a BTT MMB board, which I used on the HLTF, as I had a spare.

Hope this helps.

Hi everyone,

I've built an HTLF, but I'm currently stuck with the AFC configuration settings. Most of the available documentation seems to be for the Box Turtle, which might be part of the confusion—maybe I’m just missing something obvious!

The build is nearly complete, but I’m having trouble getting the configuration right. Unlike the Box Turtle, which requires setup for four steppers, in my case there’s only one stepper for the feeder and another for the tool head selector.

I've managed to find some information, but I'm still not quite there. If anyone could offer some guidance or help with the configuration, I’d really appreciate it!

Thanks in advance!

When you install the AFC software, choose htlf as the unit type. This will give you the appropriate configuration files. then remap your pins to suit your board.

Have a look at the configurations here for the pin definitions.

 Here is an example of a htlf config file

I like that Lineux toolchanger, I think it would work nicely on a Trident.

I have built this, but abandoned the project. It is very much still in Beta and I have spent too much time on trying to get everything to work together. Moving on to a CPAP E34M1 toolhead and the electronics, so I can get the printer up and running. May revisit the project again at some stage.

It’s working now—thank you so much! I hadn’t checked the installation properly and just assumed it was only configured for the Box Turtle by default. That was my mistake.

I still need to reprint some parts since a few didn’t come out at the right size—but that’s another story!
