Hello everyone,
I just downloaded the newest version for mac and it crashes on the loading screen on startup.
I uninstalled the previous version and cleared caches before running the newest version. I’m on OS 12.1.
Is this happening to anyone else?
I beta-tested this and also have the production version. I’m not seeing this.
However … I have a TAZ Pro and a TAZ Workhorse. The Workhorse has four different toolheads (SL 0.25, HE 0.5, HS 0.8, and HS+ 1.2). I discovered that when I selected the HE 0.5 toolhead profile Cura LE would immediately crash. But ONLY on that particular profile … no others.
I deleted that printer/tool-head combo and re-created it and have been fine ever since.
In macOS, the definitions are located in
~/Library/Application Support/cura-lulzbot/3.6
(In Unix operating system the tilde ~ is the short-cut for the user’s home directory … e.g. /Users/your-user-name)
If you are running into the same issue and you only have the one printer definition then you might need to delete/hide it. I think these are found in the “machine instances” sub-folder. Rather than straight-up deleting it … just move the definition to another folder (such as your Desktop) temporarily … then see if you can launch Cura. If that gets around the problem, then re-add your printer definition (and you can permanently delete the bad one.)
You seem very knowledgeable reading your response. Wondering if you could help with my issue.
Do you think I could take a “machine instance” from Cura 21.08 of a Taz 4 using a Budaschnozzle and put that file (if I can find it) into the Current Cura Version: 3.6.37? Does the new version also store it’s printer setup instances in the same location?
My problem is Lultzbot doesn’t seem to offer any set up on these older machines and the Legacy Cura 21.08 doesn’t work on the new Mac M2. I’m looking for a work around since I don’t know enough of how to edit the “Info.plist” file regarding Python in the programs package contents file.
Thanks,
There’s nothing special about the budaschnozzle that won’t work in a profile created in 3.6.x, but the format of the profiles/“machine instances” have changed greatly since then.
Your best action would be to create a new machine in 3.6.37, tell Cura that it’s a Taz 5. The changes between the 4 and 5 aren’t drastic as far as capabilities are concerned. They’re most changes for just generally being “better” but it’s still the same size and doesn’t have the bed leveling that a Taz 6 would have. The biggest changes are mainly centered around the toolhead. Make sure you’re not going over the max temperature of the budaschnozzle (240c), set your nozzle diameter, and if you don’t have a cooling fan on your tool head, filament settings for PLA especially are probably not going to line up well. For those filaments you are using, just compare the print settings on the old Cura with the new and you should be fine.
Well first, thank you for the first knowledgeable and very informational response. My thinking was the smaller z rods (one of them is a Taz 3 with upgrades) could effect dimensional accuracy and wondered if there were some settings possibly built in to cura addressing this? Maybe that’s just an issue for the firmware and not the slicer? I’m mostly printing PLA and there is a fan on the nozzle. And Yes, I could certainly manually do all the settings for several older printers - but that is rather laborious when I’ve found that for no apparent reason on occasion, Cura seems to restart as new and loose all its settings. All the settings and instances are stored somewhere and should copy that instance set up file so I could replace the file when and if it will probably happen again. I can’t find the instances on CURA 21.08, only the newer version of cura. If I find them, do you know if that would work to just replace a copy of the file with the printers/instances? As an FYI - I just found an article about using Rosetta to allow older programs to run on a new mac - will explore that.

Nope.
Then you should be able to use the default print settings for the Taz 5 - although you will probably want to do some quick tests on cooling towers and overhangs just to be sure.
It looks like your printer should print fine with the Taz 5 profiles, or at least be a good enough start that it won’t require significantly more tuning than if you’d actually started with a Taz 5.
