Cr10 Stopping Abruptly and Back Up Again

The 3d printing hobby is fun when things are going well simply can be frustrating when things go wrong. On more than 1 occasion, I take come home to a impress that has stopped mid-way through, and in most cases, the print ended upward existence ruined. In this article, I plan on roofing five mutual reasons your 3d printer stops mid-print and go over ways to reduce the risk of them occurring.

Hither are five mutual reasons your 3d printer may stop mid-point.

Thermal cutoffs
Power Issues
Filament Issues
Clogged Nozzle
Intermission command in the grand-code file

There is a lot more than to each of these problems than you may think, so keep reading to acquire more than about them and ways to help reduce the hazard of one of them happening.

Ability Problems

If you live in an surface area where the ability frequently goes out or has brownouts, running a 3d printer may be challenging. This is especially true if you like to impress larger objects that take a long time to print as a mutual consequence that will cause your printer to stop mid-print is losing power. There are some ways to mitigate this problem, but they nevertheless accept limitations.

How to fix this?

Resume from ability loss characteristic

If you already take a 3d printer, the get-go matter you can do is bank check to run into if your printer has the resume from ability loss feature. It should be in the documentation for the printer but yous tin as well examination this past kicking off a small-scale impress and unplugging the printer. When you plug the printer back in, you should get the choice to resume the print if the characteristic is there. If you are looking to buy a printer, you will want to make sure that the feature is explicitly called out.

While this feature is useful, it nevertheless has problems. Showtime, if you lot accidentally hit the wrong button on power-up, there is no manner to become back and resume the print (I've done this before ☹). 2nd, any time you lot stop a print, yous risk at that place being quality issues in the area it resumes at because the printer has to re-purge the nozzle and hope no extra filament was left on the print from the nozzle all the same beingness hot when it lost power.

Battery Backup or Uninterrupted Ability Supply (UPS)

The second option, which can exist combined with the first ane, is y'all can have the printer continued to a bombardment backup. You will need to make sure the bombardment backup is capable of handling the wattage called out on the printer's ability supply, but that typically won't be an effect as they don't use that much ability. The larger the battery backup is, the longer it will be able to run the printer when the ability is out.

If the power goes out where I live, its typically for either a couple of seconds or a couple of hours. The latter situation is pretty rare, so I don't try to account for that. Having a battery backup that can concluding 5-ten minutes is typically all I look for (even for my computer). Right now, I have a larger one on my printer (shown beneath) because I had an extra one available.

Here is the battery backup I recommend. It provides plenty of coverage at a fair cost. The simply matter I don't like virtually it is it doesn't tell you the remaining run time.

Clogged Nozzle

Another issue that can cause your printer to terminate mid-impress is the nozzle getting clogged. The behavior of a chock-full nozzle volition vary based on the severity of the clog. If it's just a slight clog, you may still see some filament come out, just it will be inconsistent and can pb to a full nozzle clog. If it'due south a completely clogged nozzle, you will non meet whatever filament come out, and yous would probably hear the extruder motor grinding the filament because there is nowhere for it to go. If either of these happens, I would finish the print and work on clearing the jam if you tin. That said, it'south possible that the nozzle volition need to be replaced.

Common Causes of Chock-full Nozzle

Here is a list of common causes of clogged nozzles.

Low-quality filament with an inconsistent diameter
Swollen filament from excessive exposure to wet
Hot end temperature too low for the filament type used
Nozzle being to close to the build plate
Dust or other debris in the hot end

How to prepare a clogged nozzle?

In that location are a couple of ways to clear a clogged nozzle, merely the success will depend on how bad the clog is. A common method for a partially chock-full nozzle is the cold pull method, only I haven't had much success with it. I could write an article on this solitary, and so I don't want to become into to much detail hither.

Another method is to use a nozzle cleaning kit with needles to assistance button the stuck filament through. You will want to make sure you oestrus the hot finish to help melt the filament unless information technology won't become anywhere.

The terminal option which is what I tend to do when the nozzle is completely clogged, is to merely supercede the nozzle. The process isn't complicated, and bold you are using a brass or copper nozzle, the replacement toll is typically less than 50 cents. If you are using a hardened or stainless nozzle, I would nonetheless attempt to clear it before going the replacing road because they are a lot more than expensive.

Pause Command in Chiliad-Code

This is 1 that many people tend to overlook and has caused me issues more than than one time. In most slicers, including Cura, there are built int post-processing plugins that are capable of having your printer pause at a specific tiptop or layer. If you lot accept never worked with the plugin earlier, then its probably non the cause of any issues you may be having, just if yous have, then its possible it is.

The plugin works great. It does what it's supposed to and can be helpful when yous demand to change between filaments mid-print. The trouble I have come across is if you exit Cura open and starting time slicing some other object, those settings will still be there. So if you forget to manually remove the settings, information technology can end upward in the side by side object you slice.

How tin I fix this?

The just real manner to forbid this from happening is to either non apply the plugin or make sure yous disable it afterward yous use it. It'due south easy to forget about it when you slice another object, especially if information technology's a couple of days later.

Filament Problems

Filament issues can as well cause a 3d printer to stop mid-impress, but in virtually cases, these issues can exist prevented. I'chiliad going to go over the near common filament issues and talk about how they can be prevented.

Out of filament

The near common upshot related to filament is running out of it. There isn't much you lot can do once you run out, simply you can accept a couple of steps before starting a impress to make sure you have enough. Earlier I start a print, I wait at the estimated filament requirement called out in the slicer. If I cleary have enough filament, I will just showtime the print. If its not a articulate answer, I will weight the filament spool I'grand using (subtracting the weight of the spool its cocky) to see how much I actually have. You will need to take an extra empty spool to weigh, or just have the weight.

Another option would exist to have a filament sensor that will pause the print when yous get close to the cease of a roll. Some printers come with the sensor, but many practise not. If the printer you are working with doesn't have a sensor, you tin can always buy an add on one similar the one below.

The last option here is to use a plugin for OctoPrint to runway how much filament you have used and how much should be left on the spool. I accept used this earlier, and information technology'south a good gratis option but requires OctoPrint and boosted setup.

FILAMENT SENSOR

Grinding Filament

Filament grinding can happen when the extruder motor gear grinds confronting the filament. This tin occur when there is a clog in the nozzle or something else causing resistance to the filament. The only way to fix it would exist to clear the clog or fix any is causing the resistance.

Scraped Filament

Scaped filament can happen when the filament grinds against the frame or something else along the mode. You tin can typically forestall this by tracing the filament from the spool to the extruder to make certain it'due south non touching anything and isn't kinked.

Snapped Filament

There are several things that can crusade filament to snap, including mechanical stress, likewise much moisture, or its just depression quality. This can be prevented by making sure yous buy quality filament, storing it properly when not in use, and making sure there isn't much pull on the filament during the print.

If the filament does snap and you lot take hold of it, you can possibly save the print past pausing it and replacing the filament past the snap. If you lot don't catch information technology, you will probably end up having to start the print again.

Here is a video I fabricated roofing how I store my filament when it's not used.

Thermal Cutoffs

Thermistor Issues

A thermistor is basically a probe that is used by the 3d printer's firmware to go along the bed and hot terminate at the set temperatures. It volition tell the firmware to appoint the heating element when under the set up temperature and plow it off in one case the temperature is reached. Assuming the printer has a heated build plate, it volition have two thermistors, ane for the hot end and one for the build plate.

Virtually firmware will have a thermal runaway characteristic that will stop the printer if at that place is an event with either thermistor to prevent damaging the printer and possible fires. Typically thermistor issues present themselves as a MINTEMP error, significant the temperature has dropped below the temperature defined in the firmware. Equally annoying as this mistake may be, it'southward not something y'all want to play around with or try to bypass.

Can this be Prevented?

The number one casuse of thermistor issues is a break in the circuit somewhere. In some cases, this tin can exist acquired by accidentally damaging the cables. In other cases, it may simply happen randomly. The just matter you can do to assist prevent thermistor issues is to be conscientious when working around the cables and brand certain no wires have excessive tension on them, particularly when press.

How tin I fix a broken thermistor?

The short answer is you cant reliable set up a cleaved thermistor. If you take problems with one you will desire to make sure all the wires are intact and continued correctly. If y'all are yet having issues subsequently that you volition most probable end upward needing to supplant the thermistor. The process isn't too hard but may be intimating to someone that hasn't washed it before.

Here is a video I did roofing how to replace the hot finish thermistor on my Taz 6. In that location are some things that are specific to that printer, but about of the process will be the same on virtually printers.

Overheated extruder Motor driver

The extruder motor is the most heavily used motor in your 3d printer. It'due south responsible for all filament move and is constantly making quick moves to push or pull the filament based on the needs of your print. This can put a lot of strain on the printers' electrical components, causing them to estrus up.

Most mainboards take a thermal cutoff that volition cause the overheated commuter to terminate working. If this happens, the printer will continue to behave like its printing by moving the other axes, simply no filament will really move through the hot stop. If this happens, at that place is very little y'all tin can practice to endeavour to resume the impress. You lot could effort to measure the height and reslice starting at that point, but I have not had good luck doing that.

Why does this non happen to the residue of the motor drivers?

The rest of the motors do not have anywhere near as much movement as the extruder motor. The X and Y-centrality may seem like they are moving a lot, only their movements are typically longer and more spread out. In comparison, the movements on the extruder motor are tiny and basically continuous.

How tin I prevent this from happening?

Y'all can help prevent this from happening by following doing maintenance, having proper cooling, and making certain you lot accept a heat sink on the drivers.

Proper Maintenance

Doing proper maintenance on your 3d printer will help prolong its life span and go on it running well. I don't want to go into to much item on all the maintenance required, but I did a video covering what I exercise (shown below). 1 maintenance task yous would desire to focus on to foreclose overheating the motor driver is blowing off the dust on the mainboard. Over time the dust volition build upward and will cause the board, and drivers, to run hotter.

Proper Cooling

Well-nigh 3d printers on the market today take a fan somewhere around that mainboard that volition blow the hot air out of the enclosure. You will desire to make sure your printer does have that fan and that it works. If your printer has a fan and you lot are still having issues, you can look at buying a more powerful fan, though if you get this road, make sure y'all get a fan that runs quietly (similar this one), or it will stop up just abrasive you.

I matter to note is that depending on your mainboard, the fan may not kick in until it'due south needed. So if y'all have a fan and it'south not running, it may only not exist required at that time.

Heat Sinks

Most decent mainboards accept four motor drivers with oestrus sinks of some sort on them (quality may vary), but if you have one that doesn't or you replaced the mainboard forgot to add them, you will want to correct that. They are not very expensive and will mage a considerable difference in the temperature of the driver.

Yous will desire to make certain you mensurate how much space you have and get the ones that will fit. I added a link to a standard-sized one below. The install process is typically simply peeling off the plastic and sticking the heat sink on the scrap/driver and doesn't accept much time. Only make sure yous don't take the printer plugged in when doing information technology.

Recap

Troubleshooting issues with a 3d printer can be a challenging task simply in one case you sympathize what the printer is doing, it becomes easier. Thermal cutoffs, bug with power, filament problems, a clogged nozzle, or a pause command in the g-lawmaking file tin cause your 3d printer to stop mid-print, but as I mentioned in the article, there are things you can do to reduce the likelihood of them happening to you.
