One Print at a Time using Cura 4.8 Print Sequence Feature on Ender 3 V2

Chuck shows you a feature in Cura that allows you to 3D Print One Print at a Time using Cura Print Sequence Feature. This is a feature available in most versions of Cura and continues into version 4.8. It can be handy for printing without travel or stringing but also allows you to remove a print early while the printer is completing more on other parts of the bed. Chuck shows you how to implement this handy feature in this week's Filament Friday.

I've been using this for some time now on my Ender 3 Pro. The tricky part in Cura is that the order in which objects are printed is determined by the order in which you add them ... but ... there's a trick: if you delete an object and then UNDO that action, it is as if you just "added" that object. So, after positioning all objects, without worrying about order, I delete the item I want it to print last, undo that, then delete the one it should print just before the last one, and undo that ... and so on. The final result is having the order I want: right to left (because my BLTouch is on the left) and front to back (so the X 2020 bar doesn't hit anything). And with that order, you can get away with some extra height (change printer setting in Cura) by ensuring the X axis always stays behind the earlier prints (so don't make a grid, but diagonal zig-zag pattern of objects) and the head keeps away sufficiently (which the size settings in Cura help with). I've printed sequential objects >10cm high in that way - which with normal settings Cura would not allow because of the height of the gantry being less.

THE SEQUENCE IS MORE IMPORTANT THAN YOU THINK....

Great Video as always.

One thing to watch out for (as I use this feature a lot) is if you're running a printer with filament runout sensor.

If the filament runs out the head moves straight to the home position, not a problem when printing all at once as the head will remain at the highest layer that it has printed. However if this happens when you are using the print in sequence mode and you have several prints on the bed, then the head may well crash into them as it won't avoid them on its return path to its home position.

My tip is to make sure the print sequence starts front right to right back then returns to front centre to centre back, this way the head will never meet an already printed part when parking during filament run out.

I returned to my printer to find the BL touch pin bent on my MAX and couldn't work out why, when I resumed the print with new filament it became obvious as the head crashed into the printed items on its journey back to where it had left off.

So as Chuck suggested, print order is important but maybe not for the reason you thought.

Great that you bring this up, we have been using this technique for the past two years but pushing it even further: First, we group our parts two and two, and the rotation between those two parts allows us to control precisely where the travel-seam between them will be placed.
, Cura says max 25mm height due to print head and gantry clearance, but we have raised this number to 300 mm allowing us to print any size object one at a time. As long as we print diagonal, STARTING FROM THE FRONT AND MOVING DIAGONALLY BACKWARDS, it is possible. We print parts that are140mm high this way.

Third, the method has one more advantage: we need to get as much milage out of the filament spool as possible, and this way we can let the spool run to the end and never end up with more than two unfinished parts, instead of a full build plate of unfinished parts.

We have three ender 3 pro and will print 200 parts this month with this method, itt works like a charm.
We also tried a CR10-500mm to get more diagonal length, but it was such a poor printer compared to the ender 3, it's better to add more ender 3.

I hope this is helpful for someone.

The timing of this is hilarious. I just started using that function yesterday. First time I've started something without learning it from you first.

3:05 'Skipping' all those long travels even shortens the overall printing time!

[William-McCueRC]

Chep, you've seriously helped me with everything that has to do with 3d printing. I've maid my ender 3 pay for itself 10 times over thanks to you. You've always got the perfect solution and great tips and tricks. Don't stop making videos they are great

[Peter_Parker]

Exactly what I wanted to learn, on this printer, from this guy. Just perfect, thanks champ!

[Framidan]

Excellent feature, I was waiting for this for a long time

[daltonc]

Most straight forward and best vid I've found. Thanks for helping a newbie

[ge]

Cool. Having just got my printer dialed in to have really good bed adhesion this is the final piece to be able to print multiples without worrying about one fail ruining of the ones im printing.

Tried several times before to print a bed full of things all at once. Even things that had never failed to print. Suddenly was getting just random detaches. I guess leaving one print and coming back over and over is just riskier and more likely to fail.

[AndrewAHayes]

I am going to change the measurements for the hot end size in Cura and see if I can steal some space back as I am certain they will have built a massive tolerance into the spacing

[elfenmagix]

About time somebody did this! I've been doing this on my Troxy & PrusaSlicer for 2 years after messing with the settings and figured it out. Same idea and principle, just different way of doing things (different menu options and names).

Excellent video.

[Martial-Mat]

What an invaluable feature. Thanks for the info Chuck! You say it's not the most efficient use of the bed, but it costs no more filament and prints quicker, so I'd argue that it's the most efficient use possible.

[henriklagercrantz]

Another good thing about this is you can print many small models one at a time when your filament is running out (I don’t have a filament runout sensor on my elder 5). This means I can keep printing without worrying about running out of filament misprint. I have changed the gantry height on the setting in Cura and made sure it prints from front to back and that way i can print big things as long as I take into account the gantry, a bit of zig/zagging makes it possible.

One of the best channels on here for 3d printer tips. Thanks Chep

Amazing as Always! Lifesaver! Thanks from Australia!

This has been part of Cura for a long time.

But it used to not have the "keep out box" and it was easy to end up with the print head colliding with something that had been printed earlier.

[rmanalan]

Nice, Chuck. I was actually just playing with this today. I noticed that it seems safer to start the sequence on the back of the printer since the print head is in the front of the gantry. This will give your print head a bit more room to breathe and might even allow you to drop your min/max/x/y limits so that you can fit more on the bed. Also, for taller prints, you can raise the gantry height in the settings using this method.

[MatthiasTidlund]

I noticed that when you have a printer with more than 1 extruder you need to disable all but 1 extruder in Cura for this feature to be possible to use. Cura tooltip state that the numbers of extruders that are enabled is preventing the feature to be shown but only if you browse hidden settings and hower over the info bubble.
