V3DPrinting

Thanks for you reply I haven't tried reconfiguring the printers in order to recreate my UM3 group and an S5 group, maybe it will work. But I need to have all my printer available and reboot them / reset cura connect. The reasons why I made only one group are : - you can use the Cura connect app on smartphone and have a view of all your printer from outside (yes I use a VPN for that) - same through a browser. - you have some very cool features in Cura Connect when the server is the S5 : reprint a job already done without having to re slice in Cura. By the way, the only way to have S5 and UM3 in the same Cura Connect Group is to set the S5 Group Host.. Tomorrow I will try to print a job using only generic material, as I rebooted the S5 this morning and the fact I managed to print a job with material 2 non NFC may be a good clue.

Thanks Smithy for reformulating your previous post. I'm pretty used to Cura / Cura Connect as I operate 2 Ultimaker 3 Extended for a year now with Cura Connect. I have created profiles in Cura derived from the generic profiles. See pic. When I load the material on my UM3, I just select the PLA on the UM3. Sending the job to Cura Connect, it will be pending until you change the configuration as prompted in the warning message in Cura Connect. Then you confirm the change et voila ! The print starts. If I want to do the same with my S5, in the last step, I confirm the change, the print starts and then aborts within 30 seconds. But if I take the same material configuration, change the printer in Cura to UM3E, using the same Cura Connect, it works fine. So the problem is definitely with the S5. Something in the firmware....

Thanks for your inputs. I use LAN / cable connection from the start as wifi is not reliable and with lower speed than LAN Connection. The other point is for cost reasons, I don't use that much Ultimaker filament : too expensive for PLA / ABS / PETG / ASA / Nylon then renowned brands on the market (ColorFabb, Polymaker, FormFutura, Taulman, ...). Quality is very good, but the third parties are also very good. As the S5 is commercialized as compliant with third party materials, using the Generic profile or derived from generic, it should work. I need to do some more tests tomorrow morning, as I had a print working this afternoon with the material 2 non NFC (tough is was Ultimaker PVA) and material 1 NFC recognized.

Quick update. I have tried to print a dual extrusion job, using PVA. But I put the PVA Spool in the dry box, just put the Tough PLA spool on the NFC. I've got the warning as the PVA Is recognized as generic in the S5. I've replaced the configuration and acknowledged, the job started without issues. So is the problem linked to the main material not using NFC ?

Correct. I had to reconfigure Cura Connect with the S5 grioup host and the two UM3 part of it, after resetting all printers’ queue. The issue is only on the S5. The two UM3 are behaving like before.

Just to clarify. If you set up a job in Cura using for example a ColorFabb PLA derived from the Generic PLA material and load a PLA in the UM3 without using the NFC, then the material in the UM3 will be displayed as Unknown PLA. Sending the job to Cura Connect, assigned to the UM3, it will go to the right queue. A warning will be raised asking if you want to modify the configuration in order to use the ColorFabb PLA instead of the Unknown PLA (or a message similar, don't remember the exact wording). If you agree, then you'll have to acknowledge the change and the prints starts. With the S5, it's the same scenario, but after starting the job, it is terminated within a minute, without doing anything and the job is archived in the history.

Thanks for the feedback. I am using Cura + Cura Connect + UM3E for a year now, without any issues with other filaments than Ultimaker, doing the same procedure as the one you've described. I print nearly 24/7 with the UM3E. But with the S5 unboxed from this morning, it is not working.

I forgot : I use Cura 3.6

Hi, I have broken the piggy bank for a brand new S5. I'm a 3D Printing Service provider. I've done the welcome procedure and updated the firmware to the latest one (5.1.7) Unfortunately, after setting it up, I am not able to print with it, as if the material is not detected by NFC, the job does not start : If I set up my print in Cura using for example Ultimaker Tough PLA Black and not using the NFC to detect the spool when loading the material (I use dry boxes), the material is then PLA Unknown in the S5. I send the job to Cura Connect, it is assigned to my S5, but I need to override the configuration and confirm. Then the job starts but quits within a minute and goes to the history. If I load the filament using the NFC, the job will start at once. I have two Ultimaker 3, and the same scenario works fine. I print mostly with non Ultimaker spools on them since a year now without any flaw. Is it a bug in the firmware? In that case, I've bought a 6K professional printer that standing in my office not working. Is it a new feature of the Ultimaker ecosystem? In that case, the printer will return directly to the distributor and I'll go for a Stacker S4 even if it's 1.75 filament unlike all my other printers. Quick feedback welcome.

Hi Ultiarjan Yes, that's one good option, but needs some investments and when you have covers on the UM3, there is not much room for external camera inside. Use of surveillance cameras is also a good option, as you don't need a Raspberry PI + VPN to access your cameras. As there is already cameras, web server implemented in Cura Connect and UM3, it is also easy to implement at least a pause in the end job process or best, one of the option suggested by Roderick. Given the price of the Ultimaker printer, having a view of the complete print shouldn't be an option, but part of the standard package.

Hi Roderick First, I am providing 3D Print Services on B2B and B2C, so I try to operate my printers 24 by 7 or so. For the moment, I am working alone, so I don't always go directly to my office before any meeting (my offices are 20 km away from home). When I have critical jobs (deadline or touchy prints) I like to have a view of the complete print to decide if I change my plan and rush to my office to fix the problem. So basically, my need is a view of the final product to take a decision on a reprint or fix. For sure, a snapshot of the part or a timelapse, even if all the finest details won't appear, would be a good solution. It would avoid me investing in additional network cameras (and switches, fixtures, ....) to have the feature. Thanks for you help Kind regards David

Hi to all I really like the cura connect application, specially using a VPN to have a view on the prints ongoing on my UM3Es. But the fact that at end of the job the build plate is lowered down is very annoying (to be polite ...), as you have no more view of the print from the camera. I am operating 24 hours the printer and I like to be able when waking up on the morning to check if the prints done during the night are good without going to my office. i have another printer using a Duet3d board and it is very simple to do so as the build plate just go down 10 mm and the head home X/Y, so the print stays in the camera field. Is there a way to tweak the firmware to do so? Thanks for your feedback David

Up !!!! It is an annoying regression from 3.2.1. I’m running under High Sierra. Thanks for your feedback

Hi Since I've upgraded to 3.3.1 on my Mac, I no longer have access to network drives when saving a project. Is that normal ? Best David

Hi gr5. Yes nozzle was at the working temp for the material 220 °C. And the jamming occurs when the PLA softens.

I have successfully printed my retraction test with 2 mm retraction (Ultimaker PLA settings) with my second Hardcore. Just some slight banding linked with temperature a bit low due to the run in period of the Hardcore (220°C max for 2 hours). I have done the suggested tests with the faulty Hardcore and temperature tests looks good. However the test done without any nozzle is showing some difficulties to go through the core with the filament, as soon as it softens and expands. Reaching 3,1 mm diameter, the filament gets stucked in the core, close to the heatbreak. So the problem definitely seems to be on the ptfe tubing.

Agreed, the print is pretty much simple. I've just checked the nozzle on the hardcore, it's a 0,4mm. My Hardcore is brand new, less than 20 hours printing with PLA at 235°C max, so I don't think the teflon had been degraded by excessive heat. I have another set of Hardcores, brand new for my second UM3E - which is currently back at Ultimaker, chassis had been twisted during shipping -. I have bought them in December '17 at 3D Jake too. I've just started to print a retraction test with the same spool of silver PLA Economy and the new Hardcore, using the retraction settings above (2mm retraction). I'll let you now the result. I'll do the suggested test without any nozzle too.

Hi gr5 Thanks for your valuable feedback. The issue is not at the end of the print, so I don't think it's the old gen of hardcore. I've bought them (Hardcore Pro 4 + PVA BB) in September '17, they are recognized as "Hardcore" by the printer / Cura First my settings regarding retraction are 2 mm retraction @25mm/s, and a max count of 25, no retraction between layers, no coasting, no extra prime amount. It's the same profile as the Ultimaker PLA. If I use the Ultimaker AA Printcore, I've got no issue with that particular print. See the pic of the completed part and the failed one. I've got Bondtech extruders on another printer for more than a year and half and I am pretty sure there's no grinding during that print on my UM3E. I have made the tests with another spool of the same grade of PLA (ColorFabb Economy), same results. I have done retraction tests using a different part with 8 retractions per layers, to avoid excessive number of retractions. At 1,5 mm it worked and failed at 1,75 mm. See pics. It's similar with the issues I've got when having too much retraction on a full metal hot end (I'm using E3D V6 on my other printer). So I believe there's something wrong with the ptfe lining of the hardcore.... I'm based in France and bought my hardcores at 3D Jake, so I believe I need to contact Carl.

I've done some successful retraction testing at 1,5 without clogging the hardcore. Of course I had stringing. Then going to 1,75 mm I've clogged the hardcore. So I believe there is a defect in the Hardcore. I'll get in touch with 3d solex.

Thanks Conny ! I'm doing some more testing on retraction settings before reaching Carl. Though 2 mm retraction on a Bowden system is not that much!

Hi I have bought a 3D Solex Hardcore Pro and an Hardcore PVA some months ago, and I have a slot to set them up on my UM3E. I already have Bondtech QR3.0 extruders since the beginning, so not grinding... I am currently printing some ColorFabb PLA Economy with the Hardcore - 0,4 nozzle, using Cura PLA settings for 0,15 layer height with some minor mods (first layer width, infill speed). The part is quite simple, being a plate (150 * 150 * 4 mm) with a text carved into it on 2 mm depth. The print starts well, but as soon as it prints the letters, I have a clogging, then grinding and ruined print. I've done it twice, always the same results. Then the PLA is really stuck into the print core I have printed it with the legacy AA 0,4 printcore, no issue at all. To me it looks like the retraction is too high with 2mm and there is molten PLA going on the cold zone during retraction. Or a manufacturing defect on the Hardcore. Can anybody share his retraction settings on an Hardcore ? BTW, I'd like to have the email of 3d solex support team. Any help appreciated. Thanks in advance David

Hi ahoeben Thanks for the info. If I create a custom profile for the material, it should show up in the manager. Currently it is not the case, that's the issue. Is it related to the install ?

Hi Is there anybody out there having the same issue ? Thanks David

Hi there Has anybody a clue on how to solve this issue ? Thanks David

BTW exporting materials from my previous install and importing again in my fresh install didn't worked. I don't know if it is related.
