Prusa core one

We had interesting failures in these lamps although Vancouver is wetter than Calgary.

Some of the lamps that weren't well sealed would pump in moisture in the way described.

I was wondering if having the AMS placed on top of the printer was maybe causing some of the issues. When the printer is on the AMS gets hot and would tend to cause the air inside to be "expelled". On cool down fresh air would be drawn into the unit.

I'm in Calgary and it's not really the most humid place in the country.

During the day the lamps would heat up from the sun. We had a temperature sensor in each lamp and could actually map out and see the change as the day warmed and then cooled. Switching on the lamps at dusk and off after midnight exacerbated the issue because the now lower pressure inside the lamp resulted in cool moist air being drawn in. Over time this pumping action along with occasional rain resulted in some lamps filling up with water. Literally we had a water line on some lamps halfway up the lens. Needless to say those lamps were destroyed.

Here you can see some lamps are warmer than others. The temperature display would show red when they reached 60C which they did one July summer day.

I'm still very happy with my Bambu X1C after 11 months. Print quality has been superb, with few exceptions due to external issues (tangled spool from elegoo). I have no complaints with the speed.

Needed some knockout plugs the other night, and had them in 20 minutes.
 
Co worker has the MK3 S and had held off updating to 4 and now he saw the new Prusa CoreXY. He is debating even more. He would like having the enclosure but he really wants a 2 extruder like the XL that I have but smaller build space like the Mk4.

Having just launched an 18hr print on my MK3S+, I can very well see an upgrade in my future.

Something to try if you haven't already.

Here is a print with MK3S 0.4mm nozzle, 0.2mm layer height, default settings. 2 hours.

Same with 0.8mm nozzle, 0.4mm layer height. 1 Hour.

Problem with this one is that the thing is too pretty, with too many fiddly internal clips and things.

On the upside, it's working and seems plenty sturdy, even out of PLA.

Just now wiring up a second perfboard prototype before sending out to have a PCB made, while I wait for the next revision of the body to print.
 
Sadly at this point I think prusa has gone out of my price range. I am also not to sure with bambu labs as they are not open source, but their price point is budgetable for me.
 
256mm cubed. Black Friday has had me almost pull the trigger on a P1S combo a couple times. Work is so sporadic atm it's tough to justify. Supposed to be working the full week this week, so maybe....

After shipping, GST, exchange, and additional courier profit, it's $2K CAD all in - pretty close.

Various Bambu units are half that.

Hey Bambu owners, - how is printing nylon, poly carbonate, etc. on those machines with enclosures?? The Prusa enclosure and good support for those upgraded filament types seems like a good reason to pick the CoreOne. Otherwise the performance bump is hardly better than the MK4, which I have already. It does have a bit bigger print volume.

Well, I bought a Bambu P1S 2 weeks ago (after my Ender threw a final hissy fit) and I have to say it is a very impressive piece of kit for $890 including taxes & delivery. I bought the plain jane version without the multi-filament feeder (called the AMS) since I have no interest in the extra hassles involved.

So far, I have printed without any difficulty or tweaking:

Bambu PLA (well, duh!)
ESun PLA+
Overture PLA Professional
Overture PETG
Overture PETG-CF
NinjaFlex 95A (TPU)
Filaments.ca 93 TPE
Filaments.ca ASA
Polymaker Polycarbonate

Next to try:
Overture Easy Nylon
Filaments.ca ABS

I'll update if there are any surprises.

I've been watching all the new printers with a lot of care and attention. I really want a 'better printer', but I don't want to break the bank.

I think in the light of the Bambu line, teh QIDI pro4, and a host of other CoreXY offerings, the Prusa Core is a little overpriced. Granted, each machine has it's high points and low points. But the entire industry has upped its game, much like when the PC industry adopted the Pentium and Pentium Pro - it significantly increased every important metric.

My wish list FYI

heated chamber, hardened nozzles, non proprietary software, Core XY, magnetic PEI bed, Dual Z axis motors, Direct extruder (not a bowden extruder), Fully enclosed, 375C heating, bed 120C, multiway cooling fans, and Klipper. Asking much, aren't I? -- oh and I'd like it to be less than 750$ at my door.

I'll forward this list to Santa. :)
 
If I were to trust Katie in Scotland the Bambu is the way to go if you want ease of use. So far the conversations I've had with her (she's an Electrical Engineer by training) suggest she knows what she's doing.

OTOH, I've gotten used to using OctoPrint running on the OctoPi Raspberry Pi3 but that's likely way past what people want to do. So maybe the Bambu turnkey approach is the way to go. Certainly the Klipper software model (also not compatible with Octopi) had a lot of people excited because it's so much faster.

Oh. BTW. I mentioned this Forum to Katie and she took a look and liked what she saw but also figured open to Canadians only. Yet it seems we have more than those on this forum?

The very name of our forum would suggest that we are mostly Canadian and that was our founding target. But we have certainly grown to include many others from all around the world. There is no requirement to be Canadian.

I sincerely believe she would be welcome here. We embrace a wide range of skill sets - from newbies to wise old pros. She would fit right in from that perspective.

Our membership has very loppsided male representation. Some think it is self imposed. Who am I to say no. But I don't believe for one minute that it's deliberately exclusionary. It's just an outcome not a deliberate goal. In fact, I'd say there isn't even one member on here who wouldn't welcome her with open arms.

Despite being an engineer, my own wish list is a bit less technical.

Affordable
Reasonably fast
Idiot proof
Network based
Easy to use
3D CAD compatible
Quiet
Idiot Proof
Fast learning curve
Won't be orphaned for 10 years
Doesn't require the latest PC
Easy to repair
Idiot Proof
Low operating cost
Readily available consumables
Wide consumable mat'l range
Wide operating temp range
Did I say idiot proof yet?
