Which modeling program do you use for this? That Tyson model looks great!

Check out post #20 of this thread for a pic of the correct gap.

C'mon now. It has already been stated several times that if you need these parts down the line, and you haven't already received them, you'll get them. I bought my first Ultimaker way way back when they were still sitting in someone's kitchen putting kits together. Since then a lot changed on the printer, a new hotend was made, a new feeder was made, steppers got mounted differently and more quietly, the bowden got a better mount and so on. I didn't get any of those benefits as an old customer. Yes, I know there's a difference here in that we're talking about spare parts, what I'm getting at is that things inevitably changes. If you buy a new TV today and it goes on sale the next week, you can't go to the store and demand your money back either.
They're doing all they reasonably can to make people happy here. If we are disappointed that dual extrusion didn't work out, imagine how they feel, the people who would make a shit ton of money on it. They've put hundreds upon hundreds of hours into research. That's a ton of money they're never getting back (well, ok, they've learned stuff, but you get my point).
I will work with Sander on this. This has nothing to do with demanding money back and I think you're way more emotionally invested in Ultimaker than I am. Which is cool as Ultimaker is a great company.

For any Canadians, Voxel Factory now carries it and that's where I got mine. I will have some comparison pics up in the next couple of days. From the videos I've seen for XTC on youtube, this looks like a great product.
-
Id love to see some pics of this on some highly detailed models. Im attempting one now, but my extruder is grinding the hell out of my filament and have none spare.
Link the model and depending on how long it takes I could give it a try as well. I'm currently printing the body of the Oblivion Defender Drone to have a side by side comparison.

I just got some XTC-3D in the mail yesterday and will hopefully test it this weekend if I get time. I'll post some pics for sure.
-
No, they sent it to me free of charge. I would start a support ticket right away.

While I understand your reasoning for not wanting to compensate existing customers with the spare parts right away, there is no reason you couldn't compensate those customers in the coming months. It seems like a kind of slap in the face when you offer to essentially give 110 Euros worth of parts (plus shipping if someone like me purchased them from the store) to your new customers and make a vague statement that existing customers will be able to work with the support team to get those parts if they break down. Why should people like myself have to experience definite downtime when someone who buys a UM2 will essentially have two backups that will keep their machine likely running for the entire first year? I have already had to buy a replacement PTFE coupler which cost a lot of money to have shipped to Canada.
What it comes down to is that Ultimaker is favouring future customers over people who have already supported the company by buying their product. I've already had to deal with the fact that there will be no duel extrusion which did factor into why I bought the machine, and now I also won't be getting 110 Euros worth of spare parts because I bought my machine at the start of October. In my opinion, that's just downright ridiculous.
Don't get me wrong, I love the UM2 and am still considering buying a second one, but I find the way UM has handled this situation just insults their existing customer base. I was a purchaser for 10 years, there is no reason you can't adjust your supply lines in the coming months and compensate the rest of us over a 6 month period.

Holy rambling response sword! ;-)

If heating and cooling it doesn't allow you to remove it, it might be stuck. If there is any of the metal portion protruding, you may be able to pull it out with pliers, but if it's just the wires then I wouldn't advise doing that as they're very delicate.
I had the same issue as you and the support team had to send me a new sensor and block as they said that sometimes they just won't come out without breaking it.
-
I believe there are some people here that have 2000 hours on their UM2. Personally I have 700 in the 4 months I've had mine, and only had to replace the PTFE Coupler at around the 500 hour mark. That will vary depending on what type of material you're printing regularly.
-
Did you take out the set screw? That's what holds both the heater and sensor in the block.
-
Yeah, a lower temperature would be my first change. And lowering the speed to maybe 40 if it's a small part. (Not sure from pic)
-
Their shipping is pretty expensive so I ordered three. Want me to send you one instead? I can put it in the mail tomorrow.
Really appreciate the offer dude, but let me see if I can find another supplier now that I know the specs since with my luck I'll break it and need another anyway. :wink:
Btw, 5% off Voxel until Sunday. Discount Code: NewVoxelFactory
-
Where did you purchase the new rear fan from PM? Mine is pretty loud when the printer is idling and I think I'll replace it as well.
-
I think it would be fine if you went with a larger diameter. Maybe 3/4s of an inch instead. Just guessing though as I have no idea how strong they would actually be.
I guess it depends on what you're going to be putting on that shelf.

Put your printer onto 3DHubs, get a 5% discount instantly, print a Marvin and get a 10% discount on Colorfabb...
That's great to know as I just started getting a 3dhubs page together last night.
-
Jesus, you really need to be wearing safety equipment dude.
-
Since you're in the US I would go through Dynamism instead.
-
I bought mine from Dynamism, who used Fedex to ship my UM2. The shipping cost was about $180 if I recall and the VAT around $380. You can calculate it here.

What are you using for your top/bottom thickness?

There is nothing wrong with Chinese 3D printers if you go with well known brands.
We used to use two UM2's but lately we needed to get another 3D printer but this time with two extruders.
We ended up with Flashforge Creator Pro.
Believe me or not but print quality and speed which we can achieve with as you called "cheap Chinese crap" are far better than anything from UM2 !
This printer is just amazing.
Yes, it has smaller build plate but its big enough for our needs.
Right out of the box its missing only two things, glass plate and cooling fan. We've solved these issues already no problem.
Spare parts are very, very cheap and are available just about everywhere. For example pack of 10 nozzles cost about €13-€15 shipped.
UM2 is fast only on the paper, you gonna have to print at 30-50mm/s anyway.
Don't think if its made in Europe and its expensive so its must be great which is simple not true.
Most annoying is its underextrusion issue which is not solved for a very long time.
Interesting, I'd never heard of this printer. From their website it says, "Warp-resistant 6.3mm aluminum build platform remains perfectly level under the stress of high heat." Does that mean a heated build plate?
-
Much more likely - I've seen this happen due to the filament getting tangled or even as you get near the end of a spool due to the tight radius of curvature causing problems in both the bowden tube and the white teflon isolator part just above the nozzle. Putting the filament on the floor sometimes helps this. I recommend for this printer only you print 30% slower and 10 or 20C hotter if you don't want to spend many hours diagnosing.
That would be my guess as well.

Can you make the pic viewable, it says I don't have permission to open it?

Class action suits are sometimes the only way to get a company to change their practices. The bottom line is what matters, especially to large companies like Stratasys that have shareholders and a board of directors. I highly doubt they weren't aware of the large number of problems they would see with their smart extruder right from the get go, and yet they still chose to release it.
While I have no idea if this lawsuit actually has any merit, what other recourse did their consumers have?
