First layer being printed with blemishes
uncle_bob replied to dougconran's topic in UltiMaker 3D printers
Hi I have always been a big fan of hair spray on glass. It seems to be easier to get a thin / uniform layer onto the glass. Cleanup is done with a soak / rinse in hot water. I clean and re-coat the glass when things start to lift off. That might be a couple dozen prints using PLA. Bob -
Custom material profile for material station
uncle_bob replied to PrimaryEngineer's topic in UltiMaker 3D printers
Hi I suspect that the gotcha is the magic many digits long "random" ID number. There is a thread somewhere here on just how to generate it correctly. Bob -
Hi I think I would push back a little on the "20% cost of a new printer" price for the screen. It may be that somebody is ordering in the entire electronic "guts" of the printer and tossing in a charge for 8 hours of labor. The printer isn't that old, you might do the old "how about the warranty" rock and roll 🙂 As long as the discussions stay polite and non-confrontational, there is no real downside to asking. Bob

Material Station on an S5 and Materials
uncle_bob replied to wdeighton's topic in UltiMaker 3D printers
Hi One thing that has not been mentioned: Is the spool free to feed? In other words, is there a cross over on the spool that has it locking up? I'm in no way saying that is the issue, only that it's something to check. Bob -
S5 priming filament keeps getting stock in lead screw
uncle_bob replied to DBVOLA's topic in UltiMaker 3D printers
Hi On *any* of these gizmos, buying one in the first six to nine months makes you an "early adopter". The bundle setup has only been shipping in reasonable quantities for a month or two at this point. 3D printers are in no way unique in this respect. You can spend a couple hundred thousand dollars on this or that device and find the same sort of thing. What matters is that they *do* address the issues and do so in something less than a couple years. ( hopefully closer to a month or two). If they come out with a fix of some sort fairly promptly, that's about as good as it gets. ( sitting here with the factory guy debugging a roughly 9 month old piece of gear that costs a bit more than the bundle did ) Bob -

uncle_bob replied to DBVOLA's topic in UltiMaker 3D printers
Hi I'm running mostly tough PLA here. Best guess is 70% tough PLA and 30% PLA. Bob -
S5 priming filament keeps getting stock in lead screw
uncle_bob replied to DBVOLA's topic in UltiMaker 3D printers
Hi I've been running the same sort of print schedule for at least a month now. I have never seen the issue. For whatever reason, the scrap all piles up at the side / front of the machine and stays there. It's not clear to me that I'm doing anything special other than cleaning out all the prime strings on a regular basis. Bob -

Hi So far I have never seen that happen on my machine. Bob -
Anyone tried the Ultimaker S5 flexplates?
uncle_bob replied to LePaul's topic in UltiMaker 3D printers
Hi Hair spray on glass has worked for a *long* time on the UM3. The same thing seems to be doing fine on the S5. That's with PLA and with tough PLA (also with non-UM tough PLA versions) Bob -
Hi Sounds like a defective screen. (as in a manufacturing defect at the supplier of the screens). Bob
-
Hi Sounds like it should work !!! Most of us got the S5 before the rest of the bundle. ( back orders ....). The way I *know* it works is to do it with the S5 by its self. If the manual says you can update after, then that most certainly should work as well. Bob
-
HI 1) You should have two plates - contact your dealer and have them take care of it. 2) Best bet is to simply fire up the S5 (don't worry about spools etc), exit out of the intro print screens and update the firmware. Then put everything together. An alternative would be to set it all up, but don't cable the Air Manager and Material station in. Fire up the S5 and do the same exit setup / update firmware. Bob

Serious problems with Ultimaker S5 (on 2 machines) [Solved]
uncle_bob replied to DrCeeVee's topic in UltiMaker 3D printers
Hi If we are talking about a "several seconds" sort of stall ...... a power outage that long will reboot the computer(s) in the S5. It will be *very* noticeable. Indeed, a UPS is a very good idea when printing. The biggest trick is to make sure the unit you have will handle the power involved (the bundle system is rated at 500W (??) ). Loosing a print 5 days into the run because the lights blink is *not* any fun. Since the S5 and Material Station have independent power supplies. There is the weird case where one drops out and the other does not. Without a lot of tearing things down there is no way to know which one would die first. One would *hope* that the Material Station goes second or that the S5 is smart enough to catch the problem .... Bob -

Hi If the problem was caused by a gcode error, you would (at the very least) see it on all S5 machines. You likely would see it on all machines when driven by Cura. As noted above, it does not appear to be a gcode error. Bob
