Odd that it is not working for you. I wish I could try v18.03 to see if I’m having the same issue, but the toolhead is now enroute back to Lulzbot for repair (we suspect that it carbonized the PLA filament in the print head - I would have attempted repair in my own, but I donated the printer to a local elementary school and don;t want to screw up their warranty coverage).
Did you ever try the old version 17.10 on your Mac? We’re running the same OS, and all I did was download it and run, no problem (when it’s at school, they run it via a windows laptop).
I haven’t updated to El Capitan yet, but there was a strange thing with old versions of Cura on the version just before EC (can’t think of the name). When I first got my printer it took me a while to figure out how to use Cura because when it would initially load, I’d press the control button, and nothing would happen. The workaround was to go to the menu, open the expert window, close it, then press the control button. After that, the control panel would show up like expected until you quit Cura and started it again. Then you’d have to go through that same dance.
Anyway, you might want to give that a try and see if it is an old issue rearing its ugly head again.
Yes, I did that. The Lulzbot machine did not come up. Also, when I ran the “about the Mac” system report, The Lulzbot did not show up in the USB tree of connected devices. I also tried every USB port and unplugged other USB attached devices.
I thought I already posted this, but I have a Mac Book Pro, El Capitan and it runs my MakerGear M2 just fine, using Simplify 3D and I think both Lulzbot and MakerGear use the same controller. I would switch to a new USB cable.
The USB cable works fine on the PC. It surely the Mac OS X system since the system profiler does not see the USB device. A MacBook Pro is a different animal than an iMac I think. I’m using an iMac.
Well, if you look earlier in this thread, you’ll find that Lulzbot tech support told me that it was the new Mac OS that is causing the problem. They seem to know this.
Well you said this in your first post. In the Cura software, I see no Control Button. I re-downloaded the software twice and reinstalled, still nothing. Tried on OS X 10.11.2 as well as on a Windows 7 machine, same problem.
Well I know Simplify 3D works for me on El Capitan via USB and others have used it, so maybe its the version of Cura? Its easy for a tech to say its not our problem… but others here are using it just fine?
Later I say I got it working on Windows, but it doesn’t matter. I’m having to use Windows for now to get this thing done by my deadline. I design my models on the Mac, save to a Dropbox and just print from the Windows machine. I don’t have much time to mess around with it right now. My biggest concern at this point is finding a way to make the models print smoother.
Regarding Simplify 3D, it was all I could do to get the company to buy the dang printer. It’s not the best time to go back and ask for more money to buy different software. Part of my pitch was that it used open source stuff that was free. But that’s a good idea. Once this is through, maybe I’ll go in and try some other software.
I’d guess that they are working on a update for Cura right now. If the OS X was really having issues with USB connections believe me it would be more than just one device.
I own 2 Windows 7 laptop computers and this is my first Mac. To run Corel Draw for my Laser design work I set up Oracle Virutal Box on the Mac. Installed Windows 7 and then Corel Draw X6. I need to use a special color palette to tell the laser controller what power, speed and other variables. This computer is only for when I go out of town.
If you really need to run, I would do as suggested, get an older version of Cura. When I had my TAZ machines I used Cura (Win 7) and had No issues at all.
Just downloaded Cura onto my wife’s iMac. It runs the Mini no problem.
Given my results on my Powerbook and an iMac, I don’t think this is an OS problem. Something else to try: using the SAME USB cable, plug a different USB device into your iMac and see if it recognizes that. I once had a computer where one of my USB ports got worn out (probably got the cable kicked and tripped on one too many times). It loosened up to the point where only certain USB cables would work in it. Some cables that would NOT work in that computer would work fine in another one - there was just enough variation in that cables or ports.
Well, I tried every USB port on my Mac as well as disconnected the other peripherals. I assumed the cable was good because it worked on the PC. But, the fact remains, I didn’t try any other cables. So, I guess I’ll give that a shot on Monday when I’m back in at work. You never know. If it works, I’ll post the result.
Thanks for your help.
There was a printer last month I saw that was brought in for repair because the owner had tried two different USB cables and the printer did not work with either cable. So they thought the printer was bad, but they just had two bad USB cables.
If your cables power lines are bad, it would not see the printer since the cable supplies the power for the RAMBo. But many devices do not need that power to work, so you may have a bad cable.
I know from other posts on the laser engraving forum and on the MakerGear forum Windows 10 has real issues with USB ports. The guys are looking for older computers and / or removing the Win 10 upgrade.
With the Mac OS X incremental update 10.11.3, (the “3” being the relevant number), I found the Cura software to function properly and connect with the Lulzbot Mini on my iMac. Whew!
It now seems to connect to the Lulzbot Mini after the incremental Mac OSCX update 10.11.3, although so far It has only started the model and then returned an error (serial error). Somehow I think that is surmountable though since maybe I am choosing layer heights that are unrealistic (is 0.005 too fine?).
