They supported the Robo3D R1, etc.

Also MatterControl was the buggiest piece of poo poo slicer software ever.

They made us buy a Robo3D E3 at work, and then I spent the next 3 months trying to reverse-engineer whatever stupid HTTP-based API calls they were using to fetch downloads from the cloud server we weren't allowed to connect to.

It was probably a pretty decent printer for the educational environments they claimed to be targeting. We were not an educational environment.

It is lol, every time I finish one I forget to weigh it. Helps when you have a 100g print to go but aren't sure how much is left

I just finished off two other rolls that were almost empty as well, and they weighed 150 grams and 159 grams, so I'd probably budget at least 160 grams of spool weight if you're trying to fit in a print. (More if you have a bowden setup as there'll be filament left in the tube once the end goes past the extruder.

I forgot to tighten the screw holding down the build plate once and got something similar but not exactly the same. That's the best guess I've got.

Girlfriend is looking at getting a FDM printer sometime in the next few months, and was probably gonna grab the Creality Ender 3 S1 Pro. It's currently $339 canadian, which is a fantastic price, and looking at reviews it generally seems to be pretty good (the best thing in its price range).

But, I was thinking about contributing some money to the purchase, which leads me to ask if there something in the $400-600cad price range that is significantly better than the ender?

We don't have any really specific demands; mostly going to be printing knicknacks and terrain for wargaming. High detail isn't required, but would be a nice bonus.

Even the A1 Mini is almost twice that in CAD.

I love my Bambu but it's definitely a price bracket or two up.

Not constantly making 10" tall multicolor prints with 2000 filament changes helps a lot with not generating so much poop.

Really, the waste usually isn't nearly as bad as people make it out to be, and there are tons of ways to mitigate it. Just being a little smart about it in the first place goes an awful long way.

Depending on what you’re printing, the waste can be mitigated in a bunch of ways.

  • Most important is design. The less color changes the less waste. You can mitigate this by either limiting vertical color changes or by separating each color into assemble-able parts and printing by object instead of by layer. If you have 50 layers with 5 colors per layer, that’s 250 color changes just for those 50 layers.

    But if you have 50 layers with 5 colors and only 1 color per layer, your range of color changes is 5-50 depending on how many layers of the same color are next to each other. Additionally, you can mitigate this further by increasing layer heights.

    As an example, in the model I posted below, I could have reduced the material waste from 54g to about 30g by removing the color change either on the spine or the fins on the front.

  • Next important is volume. I printed a 3 gram material object with 2-3 colors per layer. This resulted in about 54g of filament waste between flushing and the prime tower. By printing 30-ish of them, I used ~100g of material on the models and still the same 54g of waste.
    (Waste was so high on this because of the colors and filament type used, and it can be reduced further. It’s a fun print so here’s some images)




  • Adjusting waste level. The slicers are super aggressive with how much flush happens to prevent color bleed. You can typically reduce their defaults anywhere from 30-70% depending on your filament, and setting the proper color in the slicer makes it more accurate. There are even calibration prints you can do to calculate exact flush values for each filament change.

    You can also significantly reduce in size or remove entirely the prime tower.

  • Flush to supports/infill. You can flush filament changes directly into supports or into the infill of your print. Supports will never be an issue, but for infill if you’re not careful colors can show through (like black infill on white or semi-transparent colors)

  • Flush to object. You can designate a secondary object to flush into, as long as it is the same height or shorter than your main model. The colors will be wacky as hell, but if it’s something you actually want to print and don’t care about, and it has enough volume to absorb the full flush amount, you can effectively create near 0 waste multi-material prints.



There’s going to be waste. But if you’re smart about it, you can reduce most of the waste, or at the very least make an informed decision on if the model is worth the waste level.

I ordered the Eibos Polyphemus drier somebody suggested in this thread.
It finally arrived yesterday and I already dried half a dozen rolls of varying materials. It seems to be working nicely, from what I can tell. Thanks for the suggestion, whoever it was. I was about to get a "whatever" drier from Amazon.
I got some vacuum bags and pump from them as well, so I hope I can now finally eliminate one variable while I continue the endless tuning of my Voron V2.4.

  • Adjusting waste level.

I "wasted" a whole tray of Pikachu due to color bleed black into yellow. Bambu slicer is odd and I am already using cut down waste settings, but it doesn't seem like you can flush to object or infill without also using a prime tower... Which seems to defeat the purpose.

I am almost completely done with plush to infill since it tends to bleed too much, but the other options should be valid.

Acid Reflux

What I tend to do the most is not worry about the waste at all. It's a very small part of the overall process. Ultimately, a print is going to take whatever it's going to take for material, so if I really want to make a thing then I just hit the Go Button. A few grams of extra plastic isn't ever going to be what stands between me and my enjoyment of the hobby.

Many multi color prints tend to be one off monstrosities you will only ever print once. It's rare too that the 'finished' product would stay as is printed, it usually will get painted anyway

For mass multicolor production, t the waste is negligible since the waste for one item is the same as a plate full, but time goes up and out the window. I have some Pokemon stls that print really nice, and they are mostly a single color, but all the time is in the pretty pretty eyes. So much so that I just print the eye all black and just paint it in.

Speaking of, how come nobody makes pretty Google eyes? Instead of black dot on white make it white on black with a blue add on or something. I would stick them all over

Flush to infill won’t cause bleed. Depending on the filament color or if the filament is slightly transparent, you might see the infill (think painting light yellow over dark red walls).

Getting black bleed into yellow means your flushing volume values were off or you didn’t re-calculate them. If you add new colors from whatever defaults pop up when you open your slicer, you need to open flushing volumes and hit “re-calculate” to get them proper.

Black > yellow is one of the worst color changes you can do. If I were to print a tray with that change, I would either just eat the default 1x flushing volume or I would run a flushing calibration.

This here is a good one, but there are others.

https://makerworld.com/en/models/62782#profileId-69555

This one also includes some custom g-code to if you want to use it to require even less purge by utilizing retraction tricks, but I’ve never tested it so I didn’t mention this option in my OP.


With regard to the prime tower, it’s not called a flush tower for a reason. The prime tower is not really used for your flush calculations. The prime tower primes the pressure in the nozzle so it can push the filament at the correct flow rate (and etc). This pressure can also be achieved during a normal poop flush.

But when you’re flushing to infill, supports, or a flush object, after the color change the nozzle needs to be primed, or your infill layers or flush object layers will have gaps or be incorrect, causing the print to fail. Since you’re skipping 98% of the poop-based flush by using flush to x, you need the prime tower to prime the nozzle. You can reduce the waste on the prime tower when using this method by reducing the width and volume of it in the “others” section.
