  1. There’s a way to make a direct connection with the board linux and send commands to the sendgcode python without net or wifi, using the usb to serial https://www.olimex.com/Products/Components/Cables/USB-Serial-Cable/USB-Serial-Cable-F/ Is what I did use to unbrick a um3. But ofc connecting this probably can void the warranty (a20 olimex board seems to be, according to um, specially sensitive to electrostatic). With this cable correctly wired you can do a direct usb to serial to the linux and then with a bit of coding you could send the gcodes. Any path inv
  2. That’s only to send files or upload firmware but doesn’t give control over the machine since goes directly to the linux board not the white printerboard
  3. UM3 doesn’t have USB. The board does but is blocked by the frame so isn’t accessible unless you drill the frame. Even so I doubt it works without the linux board that controls the hotend amps, heat sequence and all the magic necessary to make work a 220W limited PSU
  4. That in my short experience doesn’t work on um3. But hey, dunno. Also just ethernet access doesn’t give real gcode acesss if you want to do something else than just 1 operation at the time. Like gr5 you need to use ssh to access sendGcode python program. You would need to make your own version and check how much commands/second you can actually send if the use isn’t just one at a time think. Also using sendgcode overrides some of the linux board controls like forcing a tool change, moving to parking before doing it and most probably the x/y calibration (I know Z calibracion does w
  5. +1 to that. Current zoom limit isn’t good enough (for me) to debug gcode preview issues and I end launching the gcode to s3d to just see the small details
  6. I get that I'm not longer an Ambassador like you kindly send me the notification @SandervG But. Now I'm 'Members' not a 'member' ? I'm multiple people?
  7. You can use @amedee firmware builder https://bultimaker.bulles.eu Just choose your machine, and don't change anything (unless you need it) so it will make a firmware just like the default. And change the timeout setting edit the "Display timeout Firmware"
  8. Sure I was tackling the issue and proposing how to do it. Isn’t copy paste atm and require a bit of scripting. The core issue is that even if the main idea is doable, it isn’t since depends directly on how cura is made now. And specially the formulas that link speeds or temperatures or options linked by formulas on the machine profile. So, is doable but not straightforward.
  9. Yea philosophically sure Practically if you pull the 3mf files and check the structure, see how they link the parameters to the main profiles selected (nozzle, material, quality selected) then you have another file with the changed options to that profile (overrides). You can, right now, do that, manually. But either way you need a programmer to do the script to pull a clean list of settings used (with overrides check) to get it. And with that in hand, you could by hand one by one insert them back on cura (to a point since the json profiles have in some cases formulas that can't be
  10. No need to code. I open it with textwrangler program. It shows like if the 3mf where some kind of zip file with the json txt files and the stl and info about where it is
  11. 3mf saves all related jsons (nozzles, materials, and adjusted settings). But now that I see the structure of the 3mf it could be the best way to have a ‘export’. But not without additional software to read this. It saves one file with your changes. Then the original jsons used for it. Go open one you will see.
  12. I did send a whatsapp msg to one of the tr3sdland representatives. Hopefully rhey can give him a hand
  13. That's one of the questions that did happen when the beta and release was done, I know little since I'm totally disconnected from ultimaker but afaik they don't have any plan to recycle them. Indeed there's a lot of money on each core, the black plastic for example is made on Peek on the UM3 cores. They are really well crafted and the price is good for what it is, but the lack of recycle plan to save cash or just not be able to change something simple like a nozzle (even if that could break it by a user error) is a bit a shame. But mind that, afaik, um3 is focus on pro users that don't care ab
  14. Profile info is linked to material and nozzle. So when you make a gcode only the changes are exported, just like when you export a profile, only changes are exported. The link is part of how Cura is build around materials not settings. It allows nice portability but assumes that the base profile is perfect. Edit well not perfect but allows cura to add settings without erasing your settings.. basically they can add new stuff and since they only export what you change you can keep upgrading (in theory). So, no full profiles are available nowhere but split on material, hotendtype (nozzle size for
  15. Well the heater and sensor are a 25W heater and a pt100. That can be easily removed and reused for other printers. The heater block and nozzle only work with um3. And nobody, not even china clones, sell a nozzle that could fit. So if the nozzle breaks, you need to buy a new 100€+taxes cartridge. The other option is to buy 3dsolex cores, but they are way overpriced. Ofc, if you are handy, they will save you a lot of money on the long run.
  16. This could be nice but there’s an issue. Cura profile system isn’t a ‘full’ editable (inside cura) the profiles depend on the nozzle size, material type. So even if you export the settings you never get a full profile for the current print. For example when you export a profile you only export the settings you changed on a zip format that contains json (or some structure alike) with the profiles and settings changed. But never a full profile like I get on s3d gcode header. So, while is doable, is quite difficult to do. Also, and more important, it could be really hard
  17. I had tons of troubles with the endstops on the bottom. They do lack of the necessary precision (near 0.1 error) for me. I did move the endstops back to where umo uses it and now (after buying better endstops also) I get perfect z repetition along 3 printers. But that’s just my experience ofc...
  18. There's no need IMO for that... It just works different. You set the Z height, then move near the possition and ajust the Tool offset to mimic a calibration. OFC it doesn't have fancy menus. I did get use to that, is very fast to change a configuration, since it's just a text file, you hit reboot and you change everything (not like marlin that need's a total firmware update for some stuff). Anyhow, indeed, nobody made a assisted calibration, since the duet3d supports practically all the bed calibration addons on the market. Ofc I also don't use any XD
  19. Actually the plug looks the same, but no, isn't possible. Well, better put, noone made the code. It's 'doable' but only if the controller is very basic since some of that pins are using also for internal stuff on the duet3d (there's some chats about that on their forum) ultimately, I though that I would miss the panel, but not at all, I use all my printers 3 with the phone, send the jobs from the computer and do the file selection, baby stepping for z addjustments, preheat, everything from the www phone, works like a charm.
  20. @mutley3d afaik marlin2.0 has support for ulticontroller https://github.com/MarlinFirmware/Marlin/pull/9501/files
  21. There’s an user called 3Dper on twitter that a few months ago did send me this picture (no manual or how-to) but basically what he did was rewire the board and connect tcm drivers outside cooling them with a waterbased something. He did pm this picture I don’t have more info, but... is doable If I would be on your situation I would try the so called 2.1.5 um2 board on aliexpress that some guys sell that has the stepper chips removable and I don’t remember who but someone already told me it works (can’t find the twitter where they did) IMO duet3d wifi, send
  22. Hard to tell. It might do the B matte but with so many toplayers the results will be so-so. And for the top-top of the circles probably the best for quality would be just to lower layer height on the last millimeters. I been trying to make a neosanding for layer to layer but I keep postponing it for other stuff. So much work lately and very little time to actually do ??‍♂️
  23. Dont do that. First call reseller. Cleaning it yourself might or not break warranty. Much discussed about that https://community.ultimaker.com/topic/21574-super-clogged-extruders/ here UM doesn’t like that user fiddle with the hardware like on previous machines. So, call reseller first.
  24. Bcn3d Cura 2.0 alpha uses 3.2.1 and this week they will release the beta with a few bugs fixed and a extra feature to copy settings from extruder 1/2 to the other extruder so there’s no need to do it one by one https://github.com/BCN3D/Cura/releases I would wait for the new beta this week (probably tomorrow) for smallupdates check their Facebook group or twitter
  25. Using a 0.4 nozzle with 0.1 setting. For the final production used 0.15 for speed 2. No, auto setting is the most useless setting of s3d. Choose correct nozzle size and change nozzle extrusion width to 0.1 or as needed 3. Extactly that
