Machine Settings / Firmware for 3d touch

Recommended Posts

Hello everyone,

I would love to try out the cura software on my bfb 3d touch dual extruder. Does anyone know if my machine is supported?

Most of you already know the state of affairs with bfb and cubex which left all of us who bought bfb printers high and dry. I am currently using kisslicer, but the developer has disappeared and is no longer supporting the software development.

I am looking for an alternative and although I dont own a Ultimaker, I would enjoy the oppertunity to contribute to this community.

Best Regards,

Yinzer

Johnathan from KISSlicer started KISSlicer because of the lack of support from bfb for his older machine. I have no idea what is happened to him, but I'm pretty sure he did not disappeared easy. I think he might got overwhelmed by something personal.

Note, I could not have made the CuraEngine without his help.

But, bad news from me. Cura is build around "5D" printing, which the BFB firmware does not support.

Thank you so much for the response! I am sorry to hear that the 3d touch is not supported. I also share your concern about johnathan and have tried to contact him to see if there was anything I could do to help him.

Hopefully there will be a workaround someday so that we bfb guys can use cura.

Thanks

Yinzer

I do not know if there is some BFB community out there, but maybe you can reach out to someone who can help in getting BFB support in Cura. Or someone in the Netherlands who can give me access to one.

I'm quite willing to add support for BFB machine, it took a quick look and it is a bit complex. But in honor of Jonathan and KISSlicer I'm willing to invest time for this.

G'day fellow makers,

I'm currently looking at a 3D Touch owned by my local TAFE, (Technical College).

The absence of ongoing support for this machine is of considerable concern.

I have to say that I never thought much of 3D systems using this strange bfb format.

Am I correct in my undersatanding that they switched from an open gcode format to this closed proprietary file format?

Was there some benefit to this that I'm unaware of?

In anycase does anybody know if the controller board for the 3D Touch is capable of running Marlin or Sprinter Firmware?

If not, can somebody assist me in determining the pin outs to produce some adaptor cables to connect the 3D Touch hardware to a ramps 1.4 board?

I managed to get Cura to work with a 3D Touch.

The current CuraEngine (I use Cura 14.09) generates almost usable files for the 3D Touch: it generates "M001" codes that you need to change into "M101", and the text format needs to be "ms-dos" (on my mac, it generates "unix" style text files). This is easy to fix using a text editor; I filed bug reports for those 2 things and they were promptly fixed by the CuraEngine maintainer so I expect that the next Cura version will generate files that the 3D Touch likes without the need for manual fixup in a text editor.

The only (rather strange) thing left to do is to set the "Filament Flow" to 4700%. For some reason, the "reasonable" settings cause the 3D Touch to extrude almost no plastic. Rather strange, but it works, and given the advantages versus Axon (Cura works also on non-Windows machines and slicing times are expressed in seconds and not in tens of minutes), who cares? ;) The only noticeable effect of this strange stuff is that you have to divide the amount of grams that Cura tells you by 47 (for example, Cura thinks my 6 gram model will weith 283 grams); I only tested this on one model but the result seems in the correct range.

Happy printing!

Okay, so I tried to run it and my machine says error at line 19. I cant figure out how to attach the two files for comparison, the "my media" thing leads me no where. So Ill copy and paste the first bit of each.

Clearly the bed temperature line should not be in there:

"M190 S70.000000"

You might want to set the bed temperature to 0 to see what happens.

Note that BFB support is highly experimental, and fully relies on feedback from users that are willing to experiment.

Hey Guys, I'm really interested in Cura for bfb.

I've try the experimental version of cura for bfb, I got error at line 19.

It was because of M103 mean turn extruder off, and it was not turn on yet

I removed that line and it worked.

But it didn't print in dual color as as i asked to cura asked

It tryed to preheat the extruders one at the time, and when heating one the other cool down.

Until got an error message

It asked if I want to continue and it printed in one color.

Hej Daid

It's quite long that this blog exist. I'm curious if there is now a way to use CURA to print on an bfb 3DTouch ? That would be awsome!

Thanks a lot! Marco

I do not know if there is some BFB community out there, but maybe you can reach out to someone who can help in getting BFB support in Cura. Or someone in the Netherlands who can give me access to one.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
