S3d code for Taz 6 v3

Mon Mar 05, 2018 5:10 pm

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!

Don't know why it didn't get the most important file, here it is!

Definitely start from here!

Thanks Aha!

I'll give it a try... I bought S3D for my Taz6 dual V3 thinking it was a fully supported printer but it isn't really... :-(

I also sent S3D a message to see if I should just get my money back since I don't have a lot of time to be messing around trying to make it work...! 2 days, no answer...

I'm a little scared to crash the bed but I'll follow your directions and see how it goes.

Any luck? I'm hoping it's working - just don't know what the issues are that didn't make it easier to port over for s3d.

As a note to anyone, I think you should just be able to put the bed leveling macro directly back to starting gcode (with a tiny bit of editing) if you want to do bed leveling each time.

Hi Aha

Yes it worked, thank you for your work on this :D . My Taz 6 dual V3 was fine with the Z-offset set to zero in Simplify3D (I tried it first at +2mm to be safe like you suggested but this proved unnecessary). One thing I did differently was I took the gcode for the wipe and level and put it into an Octoprint custom control using the appropriate plugin in Octoprint, instead of putting the macro for this in Simplify3d. This allowed me to create a button in Octoprint that says "Wipe and Level", and when you press it a pop-up comes up that says "Are you sure you want to Wipe and Level?". Click yes, and it works. I'm running Octoprint on a Raspberry Pi 2 server with Wifi. I thought the Octoprint control was better because I can wipe and level over wifi with my phone, whereas to wipe and level with the macro in Simplify3D I think the computer needs to be physically connected. If I continue using Simplify3D I would want to add another button for "purge" in Octoprint that heats it up and does the purge, since this seems to be a manual exercise with the code you kindly provided (on the other hand the Cura Lulzbot coded purge is ridiculously long and should be shortened).

Now I'm struggling with Simplify3d itself. So far, I can see that it would be quite powerful but I'm having a problem that's driving me crazy. Over and over, the program loses the settings I have put in and reverts to the bad defaults Simplify3D had for a dual V2. The dual extrusion wizard also sets up two colors that do not have the profile settings I selected, and/or defaults to the wrong profile... It's really annoying :x , and it's trying to revert to the Lulzbot dual V2 profile that would jam the nozzle through the build plate, which I almost did by accident once but was able to flick the machine off just in time. Maybe there is something I'm not understanding about creating a profile in Simplify3D... but it sure seems like clicking "update profile" should reliably save the settings (sometimes it does, sometimes it doesn't). I've been trying to set up a profile for PETG with PLA support, but so far there isn't enough ooze shield in the universe....!

Over the last week, Simplify3D has not responded to my requests for support through the website regarding the Taz 6 dual v3.

Thanks again Aha... Maybe if I figure out this settings issue, and find some more print profiles that I can borrow from, and if Simplify3D responds to an email, I would be happier with Simplify3D.

I tried the Taz 6 Dual V3 profile but didn't understand your notes about changing the z height. I went ahead and tried printing anyway and got a huge rat's nest of filament on the print bed, so I assume my z height is too high.

Would you mind providing additional notes on modifying the height?

Thanks!

I'm printing a two color 3DBenchy on my TAZ 6 with the Dual V3 toolhead. At the top of the Cura Dual V3 start code I added:

Code: Select all

M218 T0 X0 Y0 ; Simplify3D requires tool offsets in firmware
M218 T1 X0 Y0 ; offset for front extruder (set at end)
and at the end of the Cura Dual V3 start code I added:

While slightly off topic, if anyone knows what to use for Cura's {material_soften_temperature_0}, {material_soften_temperature_1}, {material_wipe_temperature_0}, {material_wipe_temperature_1}, {material_probe_temperature_0}, and {material_bed_temperature_layer_0} I'd be happy to fix the constant 170 temps in the above start gcode.
