Hi there Guys, i’ve been using my three roboxes for about 3 months now, and 3 up minis for about 9 months before that. Obviously the Up mini is fairly basic, no stuck filament detection, etc, so no leaving them unnatended.
Now, <span style=”text-decoration: underline;”>I know the manual says do not leave your robox unatended, </span>but what if I am forced too through circumstance?
And I don’t mean unatended as in a different room, but a different building.
What are the risks? Surely the entire thing being enclosed means the chance of the nozzles igniting something is fairly low, but what about heat from the extruder motor? I’ve read one or two horror stories from older printers igniting due to that. Are there any additional safeguards built in to the robox, or issues that could arise?
I’ll mention again that I’m already aware that CEL do not reccomend you do this.
Thanks in advnance!
I never trust my robox alone, plain and simple.
The first 3 - 5 layers, depending on the complexity, I watch that everything is fine.After that I go check every 30 min, hour or so.
One of the things that can happen is documented in the forum a few times with pictures:
you can end up with a ball of filament around the head, due to bad adhesion to the bed,
for whatever reason that was caused.
If you have bad luck, it can damage the print head.java (EE), JavaFX, HTML, GIS) programmer, database wizard, framework inventor, looking for a job ! http://roboxing.com/wizards
Oh yeah, watching first layer adhesion is of course a must, and a habit I gained when working with the PEI bed.
The balled filament issue is something I have yet to experience with the robox. Its something I have had with my other printers, but never seems to happen here.
Would you feel any more comfortable if you were only ever printing the same model over and over, with zero failure rate?
I leave all three of mine all the time. I leave them overnight, while I run errands, etc. I have never had an issue. I always watch the first part of the first layer, but I haven’t had a part come off the bed that ever did more than leave some spaghetti on the part next to it.

See my 3D Hub site at https://www.3dhubs.com/phoenix/hubs/benWe leave ours unattended also and often for a whole weekend.
We have smoke alarms directly above the machines which are connected to our security system and IP cameras allow us to keep tabs on them.
It’s worth noting though, we’ve never had a failed print despite getting though several kilos of material so far. Good job CEL!
BUT our printers are in a separate outbuilding which is detached from the office and residential properties. If using a Robox in the home I would encourage following CEL’s recommendations for piece of mind.
Same here. I leave min unattended all the time.
In case a filament is stuck, the Robox will halt and start flashing.
I’ve had a case already where it detected the table didn’t heat correctly. It nicely issues a warning and goes in to a safe pause mode. Same for the head. So I think it is reasonably low risk.
Bit of topic, but you can have (and I’ve had) the same discussion about your washing machine and dryer. Lots of fires by unattended wash dryers:-( http://www.nfpa.org/safety-information/for-consumers/causes/dryers-and-washing-machines
It is never 100% risk free.

I wish I could say my Robox was a machine I could leave unattended.
Fairly recently there was an incident where the printhead started heating uncontrollably mid-print. By the time it was around 20 degrees hotter than it should have been, AutoMaker cancelled the print and supposedly performed the “head cut-off”. However, it did not work as planned and the head continued to heat.
If I had not been in the room at that point, the result would have been a disaster.

@hawkeyethehacker Your overhead incident was due to failed components. If you have resolved that issue, you will not have it occur again unless the same component fails. There will be an update released soon that should eliminate the problem completely.
Probably the most that would have happened is some smoke from your head as the filament leavings burned off and if you used PLA or ABS, the head may have been clogged if it sat too long. The heater can’t really get hot enough to melt anything, especially with the fan running, and the Robox would have alerted you to the error and not continued. The other thing to note is that this overheat issue almost always occurs at the start of a print. I can’t remember a single instance of it occurring during a print. This, coupled with the bed heater safety, makes me very confident leaving the printer unattended once it has progressed into the print.

See my 3D Hub site at https://www.3dhubs.com/phoenix/hubs/benI did get the head checked out by CEL and replaced the front panel of the X carriage. All has been great since.

I left my Robox a few times completely unattended at home but only when I had chance to monitor it remotely - Raspberry Pi with attached camera overlooking at Robox’s print chamber + rbx toolset, mentioned here or here, so I can stop the print in case of ball of spaghetti @pelgrim referred to. At one occasion, sadly, I needed to use command to stop the print as it went wrong. At least web page rbx-toolset provided gave me the ‘stop’ button. Other times it was fine. Last time I was printing a mac stand for a collogue of mine from work, he was doing the monitoring for me - fascinated with the way Robox works.
For those that want to stick with 100% stock software, just install teamviewer and a webcam. TV supports watching the camera and using a smart phone / tablet one can remotely cancel a job using AM if you start printing noodles.
rbx-toolset works quite well but I wouldn’t want to expose it to the internet without an additional layer of security.
I’m sure CEL is working on an awesome print server… at least I hope so as I will have no less than 12 robox running by the end of January and my own print server solution wouldn’t be production ready until at least Q2.
I’ve seen RBX-toolset mentioned a few times now, but all I can find is its Github.
As I understand, its a command line tool for controlling multiple robox printers, with greater options?
I can understand why people would want that. Trying to get all of my roboxes working in Automaker gives me a headache every morning.I also just heard about the reel button double-click to repeat print function. Again, something ridiculously useful, since mine print the same thing 90% of the time. Why on earth isn’t this in the manual?
Is there any UI for the toolset? I’m not good with java.
