  1. Discussed with @CarloK While the XY calibration does re-calibrate for the smaller nozzle the print still happens with a static layer height, maybe the max mm/s that is pushed trough the nozzle is exceeded causing grinding. I could generate the gcode for the XY calibration with a smaller layer height, would you be willing to test that?
  2. Missed that SD card bit indeed 😅 While the we are still making bugfixes for the um2(+) I don't see time for new features likely. Have you tried @tinkergnome's tinker firmware? It has a bunch of features the regular firmware does not, if it doesn't already have that feature someone might be able to add it.
  3. So if you abort a print the UM3 and S5 have a retry option at the end of the print. And the Cura connect print queue software (running on the same printers) has a list of old prints you can duplicate. Does that help?
  4. Have you done a cura connect reset on the printer? There is no official PPA AFAIK so this is out of our control, we can't make old software magically do new tricks. Please use the AppImage version provided for Linux. (and yes try doing a cc reset)
  5. never mind.... It seems silly that I can't delete a post, but I was incorrect.
  6. Of course you can more easily set some pins to create a short circuit and doing so would be unintended use and the damage caused would fall outside of warranty.
  7. It will still abrade the printcore and ooze a bit more but the wood fibers have an easier time being pushed trough the nozzle and I have less clogging especially at higher temperatures (to create fake wood nerve/layering) as the nozzle does not have a flat bit just before the exit. | | | | AA \ \_ _/ / \__| |_/ | | | | BB \ \ / / \ \ / / \_| |_/ Perhaps this ASCII art cross section illustrates the difference in internal geometry. So the BB core is intended for materials that do not easily flow trough that flat (even if the hole is the same size), while the flat does a lot to prevent oozing, it's a trade off.
  8. Some phone providers make it just as easy, and the user still gets access to the root(administrator) account of the device, so rooting is what it literally is. Ultimaker provide the tools and instructions (on this forum) to "root" the printer that makes it even more questionable to hinge warranty on that IMHO. I have no idea what Ultimaker's official stance on this is so I'm sticking to quoting fact.
  9. A) you'd have been warned (in Cura by a yellow color, in the printer by a line saying it is not recommended) B) it works fine and it is even advisable to print wood-fill PLA with a BB core for instance. The one thing you shouldn't do is put PVA in a AA core. this quickly makes the core clogged beyond recovery. (*barring drilling the gunk out which damages the core) the PVA flyer with your printer does specifically mention the BB core. At least it is listed correctly on the website: Swappable print cores Faster print core changes mean higher uptime and easier maintenance. Your Ultimaker 3 comes with print cores for build (AA) and water-soluble support (BB) materials. The app can monitor the printer remotely already but it only gets events such as print finished, aborted or started. not a camera stream, the cloud solution we are working on (I think we have 1.5 dedicated cloud engineers in a SW department of 40-ish people testers/developer/product-owners working on firmware connect, Cura, app and cloud) includes slicing in the cloud and sending prints directly to the printer from anywhere. AFAIK no remote camera stream. so that depends on what you mean by monitoring. And yes @kmanstudios this is forcing us to implement better security everywhere connect is currently completely without security this will have to change. Great to hear, and improving this is indeed out focus at the moment!
  10. I would compare this to rooting your phone And well as far as I know it's just not legal to consider changing the software as breaking warranty. Then again I'm a software developer not a lawyer...
  11. If it helps it would for instance be very easy to expose the current and total layer counts via the printjob HTTP REST API the same way progress (0 to 1) is currently exposed here: http://<insert.printer.ip.addr>/api/v1/print_job/progress BTW: There already is a way to view the current Z height during printing: http://<insert.printer.ip.addr>/api/v1/printer/heads/0/position/z
  12. I've never had this problem with Ethernet, I would suggest doing the factory reset as it should be the default after that if you then skip the wifi setup. You can always make an impromptu mini lan with a router but indeed you can also plug your laptop into the printers Ethernet port cross cable (though most modern computers can use a normal cable) directly or use a hub/switch and the printer should come up with a link local ip address, https://en.wikipedia.org/wiki/Link-local_address these start with 169.254.x.x depending on your computer you might have to configure an ip in the same range but most systems do support the link local protocol, it just takes a bit more time. That way you can also find out the mac address. Though I thought the mac address was also in the networking menu (I just checked the code (as I don't have an S5 present) it shows the mac address of the active connection though so you need to set it on Ethernet first), so yeah that would be the simple path. I Had no problems with the first run wizard it is a bit restrictive(requesting specific materials) but you can do the steps you want and then skip everything else. If you really can't get networking to work you could also get a serial cable there are some instructions from the olimex folks that explain this. NO! What you seem to want is not a simple setup, changing the steps per unit by re-compileing marlin and putting that on the printer is more complicated, this is changing one file on the printer. I only mentioned this as an alternative to that.
  13. I meant on the printer. use developer mode to ssh into the printer and edit the file there using the vi command or use winscp to edit the file with windows. This will save you from editing and compiling marlin at least. Please note that a microstep in the S5 is half the size as that of the UM3 so the printer should have a higher resolution, so if you're not getting that resolution, before doing anything I'd check the tension in the belts, that might be the problem instead. good luck!
  14. you can set the steps per unit in the machine configuration file for both the UM3 and S5 located in /usr/share/griffin/griffin/machines/ have a look at 9051.json and um3.json
