Would love this feature for my S5, I can't find any reference for it so I assume it doesn't exist yet. My situation is that I need to have jobs run to really strict timings, and if I could schedule a job so that it starts in the middle of the night and finishes just minutes after I arrive on site then I'd already be 1 job up in my day. I won't have to wait for any heat-up time as well. Is this something that might be considered? Thanks!

I've had a job that hits/destroys the part on finishing, but when I print the exact same file again the problem doesn't happen...

yep, we get this every now and then. Usually destroys the rubber around the nozzles, often snaps the job and pushes the glass way off. We had a thread about it not so long back. Seems to happen at random no matter what firmware we use.

I'm off work for a week but I'll get a log next time I'm in. It looks to me like it probes with nozzle B, leaves a bit of ooze. Then nozzle A probes the same spot and it fails, I assumed because of the height difference due to the ooze. The material station is just useless for us really. We run the printer all day every day during the semester and we use cheap filament due to the quantities involved. They almost universally come on spools which are too wide to sit in the station so we have to loop them out rendering the station totally pointless sadly.

yes i have the material station, which is another can of worms as almost 90% of my filaments dont actually fit in the thing so i have them outside and looped in and the continuous printing from when one runs out and changes over simply doesnt work, the new filament feed never makes it to the head. If it wasnt for the fact it makes the printer look impressive id remove it, it was a total misfire sadly. But im kinda over the above and moved on to some of the other horrendous things that really taint an excellent printer, one of the worst being what is discussed in the thread, its the slowest thing in the world. Say i get a probe failure, which i do maybe 25/50% of the time due to oozing getting left from the secondary core when it probes the first spot, it then takes 30 or 40 minutes to cool down before i can attempt it again. I literally just want to click retry, nothing else. In that time ive got students stood waiting or if its an overnight job which i set off before i leave ive got to sit here in the office staring at the printer for 40 minutes just to be able to click retry. Over the time ive had the printer its been literally hours and hours lost, its pretty crazy. I understand the technical reason for it, but if i lose 2hrs a week to it for a full year then thats an unacceptable loss for me. Oh and im on firmware 7.0.2.0.

yep. Most frustrating thing in the world. I use UltiTuner which a member on here made and its excellent but doesn't/cant fix this. The most annoying thing is a probe error just as you set off a night-time job before you leave for the day. Often i have to stay back 30 minutes while i wait for the thing to cool down just to then immediately click confirm to heat up again. Its just wasted time and energy. Ive probably lost hours and hours of my life sat waiting for nothing...

hi guys. I use Digital Factory 99% of the time. I have my library there, i send all my prints and reprints from there no problem at all, its great. But often i want to see the stats of the jobs but i cant seem to find that info unless i go to the printer directly through the IP. That i guess is also fine, but inconvenient as i need to be on the same network, but even more annoying is that when i do connect via the IP i get a warning/info bar asking me to "upgrade to Ultimaker Digital Factory". I have done, i have it! so why is the message still there and why cant i suppress it? there is no means to close that bar down, its surely a bug otherwise its just a persistent nag. Ideally i can access these real-time stats via the factory but if not then at least i'd need that nag warning to be able to be closed down. Cheers guys.

it might be useful to those who use a bed covering that gets damaged on the S5. probePositionalGrid.pdf

cheers Tom, thats great. It kinda gives some clues but its pretty difficult to get that accurate as i assume its taking into account the position of the nozzle in relation to the carriage etc. Even so, thanks a lot for it. Id worked out myself that 40mm square is was the way to go and through trial and error ive got it pretty much bang on in terms of margins. Obviously this is pretty useless to most, but it means i can position my models around the impact marks in the kapton made from the red hot nozzle probe. Be nice if the probe was done with a cold nozzle really, as it cools as it goes. For example as the probe goes right to left impact marks get less and less until none at all, so Ultimaker saying the nozzle needs to be hot to get an accurate result doesn't really ring true. I know people say its not designed for the use of kapton, but it means i can get an absolutely mirror finish on my model face so no post-production required, no brim at all to remove, zero warping and no cleanup.

hi guys. I use kapton on my UM5 glass bed, its the finish we need (as the bottom surface is the face) and the adhesion is perfect. However the hot end damages the surface while it is doing the initial bed leveling probe. I turned off the levelling but my manual levelling isnt up to it, i want to keep the auto levelling. The question i am asking though, does anyone, even Ultimaker themselves, have the bed probe pattern drawn out perhaps as a DWG or similar? i attempted to draw it out myself based on the impact marks on the kapton and its close but i would be interested in an EXACT version if that is indeed a thing. See below gabs to demonstrate what i mean, i can position models of a certain size around the impact points and then type in the positional values into cura to move the model to that same position from center. this saves the model surface and means zero post-production to sand out the marks.

Indeed. You could potentially edit the code to do the job, quite easily I'd imagine. But I'm in the opinion of I shouldn't really have to, as this was a £10k machine... Still, it's something I'll look into if the problem persists.

For info, this is how I run almost all my spools as none fit in the material station. Pretty useless to be fair.

Kapton gives a brilliant gloss finish I've found, and you can print without a brim with ABS which is great. Lasts maybe 10/15 prints before it starts to lift.

It's crazy annoying. We run pretty much 90% of our material external to the material station with the door propped open with magnets because the spools don't fit. I have the spools sat on frames with bearings for low friction, helps when printing high elastic TPU as well as it reduces the friction from the station rollers on it. Surely making the station bays adjustable to the width of your spools would be beneficial to the users.

For info... This has started happening to me again. 4 prints in a row now. Why does the head have to glide over the top of the model so very closely at the end of the print? Surely lowering the bed 10mm or so covers all potential collisions with a warped part? Absolutely no need to glide so damn closely. My part isn't even warped, it's totally flat but it still collides, no idea why. Only a matter of time before the glass bed gets destroyed no doubt.

@Smithy, brilliant tool, thanks a lot. Made my workflow a hell of a lot quicker, literally saving me hours a day in waiting time. One question though, is there a way to "remember" the last auto-adjusted height rather than have to set a manual level? my manual levelling skills are not as accurate as the auto procedure. Disabling it is great though, as it means my kapton sheets dont get wrecked with a red hot nozzle touching it repeatedly.

3 prints later, hasn't happened again after the new firmware.

same issue here. Finding a problem with this printer every day now, driving me crazy. The head has obviously collided with the job after the print and it has forced the glass bed right over. Thats 2 jobs in a row now its done this, its also tore away some of the rubber protector around the nozzle. Why lord why, why cant you just work like my Ultimaker 2 does 😞 *I've just upgraded to 7.0.2, I'll run again to see if the problem remains.

ie, station C and D both have Black ABS, same brand and size.

its the exact same type of material and spool size yes. Basically like for like so it will change over when its out. Or at least... is meant to.

mine is quite often on and off, and we have a gig connection here. When im at home, the digital library is painfully slow as well i have found. When it works it works great i must add, very convenient. I often find it loses connection when im uploading a job which causes Cura to just hang at "uploading model" that never gets there, i have to save the project, close it, reopen it and send it again.

same as above, i had to take it all apart and flip it over to manually push out broken PLA and it was fine again. The material station is the bane of my life currently, wish i hadnt bothered as i spend half my time trying to work around its annoyances.

a follow up. This has just happened again. I have allowed the filament to run out twice to test the change-over feature, and it has failed both times. So thats like a 100% failure rate on this... see attached for how far out the filament was this time. I mean there is nothing else i can do, when i load the material as normal, you basically push it into the hole on the material station and there is nothing else you can do. This is really frustrating, not just the loss of the job but the horrible amount of time it takes to get back to a useable state. The S5 is such a great machine, but some things of it are just crazy slow and frustrating. Does anyone have any advice for this? Tension is totally fine, if i were to install a roll of material it would take it just fine, it only fails on the change over from an empty spool.

defo going to look into that Smithy, just need time when the printer isnt in use! its pretty much 24/7 in here with really long jobs. It looks great though. Most of those commands should really be in a "developer/pro mode" within the firmware, especially the bed levelling as our bed never moves and the hot end wrecks the kapton. Im defiantly gunna give the tuner a go hopefully this afternoon. What does this do in terms of warranty on the machine...?

I third this. Drives me absolutely mental. A tiny bit of ooze and the probe fails, leaving me having to stand there for 30 minutes for it to cool down only for it to then have to immediately heat up again for round 2. Many a time I've gone to set a print off on my way home and I've ended up sat there just cursing at the printer for another 30 minutes. And like above, I default back to my UM2 many times because my S5 just takes sooooo long to do anything, never mind the tedious bed leveling every single time. "do you want to level bed, might result in failed bed adhesion,Yes/Skip" disclaimer to the user, surely! But a button for a quick failed print retry with a hot bed, please!!!
