Hey! I am trying to make an old Taz Pro with legacy dual extruder usable at my current job. We are having a ton of issues with it and its been sitting dormant for almost a year now…
The first thing I want to try is creating a config for orca slicer to allow other less experienced coworkers to easily pick up the workflow. Cura LE just was too much of a difference for them,
I am looking for an orca slicer config (even for marlin) that is updated for dual extruders. If anyone has any guidance or configs themselves I would gladly appreciate it!!
I am actually putting finishing touches on the OrcaSlicer profile right now and will be submitting a pull request to hopefully get it in the next release. It currently uses the same startup GCODE (with variables translated) as CuraLE 4.13.10, so there’s still oozing issues, at least with PLA. CuraLE 5.x that’s in development handles it differently, so I’m probably going to swap over to that startup GCODE before I submit the request for it to go into OrcaSlicer.
You’ll have to be running the Beta-2 of OrcaSlicer 2.3.0, due to the filament library changes for it to work. To use them, unzip the contents of this zip (lulzbot.json and the lulzbot folder) into your OrcaSlicer 2.3 resources\profiles folder. In windows it’s C:\Program Files\OrcaSlicer\resources\profiles. I don’t know where it is in other operating systems.

Thank you so much!! I will let you know how it works on my end!
Do you have any tips on mods I can do to make the machine faster? I have built vorons and other klipper machines in the past so I have experience with that, but if there is some less involved options to try first I’d rather try those. Currently our other printers can push at least 100mm/s with 5-10k+ accels so the stock 35mm/s isn’t cutting it in terms of print times.
To speed it up? Add lightness. Replace the massive dragchains with a CANBUS umbilical. Replace the mainboard with one that supports CANBUS and Klipper. Replace the massive printhead with an Orbiter v3-based toolhead with a high-flow hotend. That foregoes the universal toolhead mounting system and more weight.
That’ll give you something you can go faster with on the X axis, but the Y axis is still quite heavy and won’t go much faster, and even if you did, you’ll have to slow down significantly or the part is going to sway.
And after all that work and cost… well, you’re going to be slower than a $600 (or less) CoreXY system.
Yeah, I figured it was a longshot. It is just such a heavy toolhead/mounting system. The titan aero extruder is just lackluster too. I get so many issues with print fails due to filament grinding and shipping regardless of what tension I try. Seems like there is no in between.
I love my orbiters on my personal builds but I don’t think it would be worth the effort to try to design an adapter for the legacy dual head.
It’s insane how out of touch lulzbot is. The fact that they are trying to sell any of their toolheads ALONE is more than the cost of a new corexy printer, all with subpar performance.
So, the resonance graphs on the Taz Pro are… interesting. The X axis is relatively fine, and can be improved somewhat with a lighter toolhead. But the Y axis is just terrible. It resonates at such a low frequency there is nothing one can really do about it. The Y axis will limit the acceleration to like 1500 max, so you cannot print fast on these machine without ringing.

All my “taz” model printers look like this, graph-wise. This includes a Taz6, a WH, a Pro, and a Pro XT. That y axis is just not well-suited for speed. Something about how the Y axis is designed and mounted to the tall narrow frame, leaving the y axis oscillations no real place to go.
I would focus your attention on making it print better, which you definitely can do and can do well.
