Rapman 3.1 prints but no filament feed. Help!

[perolalars]

Hi
Hope someone can help. I have a Rapman 3.1 and used Kisslicer earlier for slicing but want to use S3D instead. Have made some tweaks on the Rapman Touch profile and slicing works fine. When saving the gcode I have to rename the file format to Rapman native file format to .bfb but it seams to work...Starts the print and it heats up the extruder ok but my problem is that the extruder dont extrude any filament. Have tried to find any info on this problem but no luck.
Attached is two files in .bfb format (it opens in Notepad) one is from Kisslicer and the other from Simplify3D, kiss file works S3D dont.
Is there something missing in the gcode to trigger the extruder to start feeding or are there other faults in the S3D file?
Please any help very appreciated!
Regards

are you running the simplify3D gcode through some sort of program because it looks like the s3d file has extra new lines everywhere. In the latest version (2.2.2) it looks like they updated the bits from bytes profile and it has been working fine for my printer. I contacted support and they said to get the newest profile when updating from an older version, go to Help > Reset All Settings. When you re-open the software, choose the Bits From Bytes profile, when saving a print file now, this newest profile actually saves a .bfb file that should be ready to go

Hi habloIngles
The only Bits from Bytes profile I can see is for BfB 3D Touch profile and thats a more recent printer then Rapman 3.1.
And to save to .bfb I have to rename afterwards the gcode file S3d puts out, I cant save or export to .bfb!!
So what to do?
Was a bit confused when the Kisslicer file had a large "header", with printer info, much larger then S3d had.
I going to make a uninstall and reinstall, but I already done that one time...
And I use S3d 2.2.2.

After uninstall and reinstall still just can load 3D touch printer profile and can only save as .gcode not .bfb...

You shouldn't have to uninstall and reinstall, going to Help > Reset All Settings should work fine.

I've been using the Bits From Bytes on my RapMan printer just fine, check the scripts tab, at the bottom of the post-processing scripts, their should be a line:

Code: Select all

{EXTENSION "bfb"}

When you save toolpaths to disk, s3d will generate two files, one with a .gcode extension and one with the ready to use .bfb extension. I used to use KISS as well with my rapman, and i saw that huge header as well, but it seems like the file doesnt need it, as my printer has been working fine wihtout that lengthy header

Hi and thanks habloIngles
Ok great so suddenly it worked with the .bfb file, slicing ok, start the printer, it heats up ok and when up in temp it primes quite a long string first, but when it supposed to start printing the extruder dont feed anything.
The display at the printer reads that it should run in 30 rpm but it dont move at all.
Strange thing is when it primes it shows 0 rpm but then the extruder works...
Any idea?

After trying to read the difference of the code I found that on row 18 it says M103 witch means "Turn all extruders off" and when deleting that row it starts to print like it should.[img]

But I just cant edit that row in Notepad, then the printer cant read the file anymore.
So how do I edit the setting in S3d so it dont writes that line?

I have the M103 there on my bfb files and they work fine for me. I don't have double Firmware and Checksum header though, I don't think that should be there... I would contact support, they helped me get up and running before the latest update with the BFB profile, but with the newest update and bfb profile, I pretty much slice, save, and print without any modifications.

Ok I take it to support then
Many thanks for your help so far.
