Crossposting from Lulzbot forum for everyone like me that was really frustrated with Cura and really wanted an S3d profile for the Taz6 v3 dual extruder head! It's not perfect and I'm definitely looking for help, maybe something official from the s3d guys. Feel free to take what works and integrate or discard! I'm just looking to get working prints so take what you can use and toss the rest!
Got a working fff for everyone needing it for s3d! Definitely need some testers for it and probably some small tweaks. Some warnings first:
-Check your z offset! First switch to s3d kept crashing into the bed and left me some deep gouges after nearly ripping off my extended z probes. I recommend taking these FFF files, then adding in a +2 mm z offset to start, press print, then stop it and lower your z height to the bed using machine control to make it so that you get the z offset to exactly 2mm below.
-I removed the auto leveling code from the starting script and put it in as a macro (attached as text). This makes it so you have ONE time to level it and you don't have to wait on nearly as many heating restarts. This is really helpful to remove a bunch of purges and if you want to use the fff file for only ONE extruder printing. Go into firmware configuration in s3d then paste the text in the text file into the macro. Definitely open to help if someone wants to make this a simple gcode file so I can decouple this onto an SD card again (maybe just change this to .gcode and I'm done? I'm not sure)
-Understand that the autoleveling and the starting scripts are slightly decoupled - DON'T save the offsets later with M500 or it can mess up the routine (I fixed it at least once by reflashing firmware from Cura). s3d doesn't like -X offsets, so it makes it work with Y+13, but that's not the way it's done in the firmware and I haven't made the two fit.
-Note that s3d seems to pull from one then the other oddly, so I have two possibly slightly different processes for the right then the left. The left is the start scripts and the right is the end scripts priority wise, I'm not certain though.
The files are as follows):
Taz 6 Dual v3.fff - The code working for s3d, I've had to use this one and the RE version for the Right side, might have slight differences I've been tweaking?
Taz 6 Dual v3 Right Extruder.fff - Should be the same as the left, but not 100% certain. S3d ignores some code in one and not the other
Right Extruder print only.fff - Use this to just print from the right extruder if you want single extruder working.
bed level macro.txt - paste into the firmware under a macro you like, just press it and it will do the whole leveling sequence
These are working for PLA, still trying to tweak for the Polydissolve, and keep getting distracted. But this stuff works at the moment. Help, feedback, improvement all welcome!
