Extruder Jam and stuck fillament Pro2

[walleywalker]

Use fan mods.

I am, I have all three of my fan ducts modded with larger openings for cooling.

RAISE3D I have the same exactly issue and is so really annoying. Please let us know if you are working to solve this issue due to apparently is a design problem. I would be able to buy another "feeding system" but you need completely make sure that it would solve the problem. Really the machine is not to bad just need to improve. I bought it for business purposes but I'm kind of disappointed. So please confirm if you would will to solve this problem or not.

Thanks...

Would you like to share us some pictures of the print result with Raise3D Premium PLA? We'd like to help based on the pictures.

Hi VIcky I just want to share that the problem was fixed however I'm not pretty sure what was the solution, so I list the different activities I did:

-Upgrade the 2Pro machine
-Change the left hot assembly by a new one.
-Use the extrusion width on .4mm instead .5mm
-Use the fan mod moving the frontal fan as the community recomend

The final test I did on the left extruder was print a conductive pla piece that I never could since I have the machine. It did it well and now I can print normal PLA and PETG.

Please continue performing your analysis to find the root cause of the problem and please share if the problem was something related with hardware or software and what the Raise community can do to fix it.

Thanks and Regards.

Thanks for your update. I thought the issue might be related to hotend. We do have many some jam cases on Pro2 solved by replacing new hotend.
If any Pro2 owner has extrusion issue and would like share us some pictures of the result with the default PLA spools attached with the printer with the original hotend from the very beginning of use for diagnose, please feel free to contact us at http://help.raise3d.com.

Is this offer exclusive to jams on with Raise3D PLA only?

It's not. But if your jam is due to hardware, you must have at least under-extrusion or jam result with our filament as well. Which we are more familiar with what result our filament can reach to help diagnose the issue.

I have a similar nozzle jam on the raise 3d pro 2..

[X12]

My Pro2 Plus: Yep, same story. Went to print PLA on left extruder and it is clogged. Disassembly of hotend required again.

[Naser404]

I too am having jams on my pro 2 and with two machines and not just one. As i mentioned many many times on this forum before this is a common issue and an indication of a flaw in the Pro-2 and Raise need to man up and admit it and also fix the issue.

And this will not be fixed with a software update.

[ocelot27]

The only solution is ditching the Raise hot ends altogether or getting the liquid cooling set up. Very sad Raise won't address this - the marketing on the website says the hot end can print materials up to 300°C - wouldn't go past 240 on a cool day with the printer open!

Class action anyone?

I too am having jamming issues. Printer worked fine for about 6 weeks then jammed using PETG CF. I changed the nozzle to 0.6 and was able to complete the job. However, both 0.4 and 0.6 nozzles stop extruding after 20-30 minutes of printing. I can clear by reloading but most prints fail after a short time.

Do you only have issue with this material or also with other materials?

[ocelot27]

Try the blower mod - works like it was meant to - even with tiny heat sinks and a servo in the way.

My replacement extruder has arrived, could someone guide me to the instructions of disassembling the extruder head completely and putting it back together.

I have posted a pic of my nozzle jam above. So I need to remove almost everything and then get put it back

[Vicky@Raise3D]

I found some steps how to take the extruder off. Please see whether it can help you put the new extruder back on or not.

I am having this issue and after 3 weeks with tech support I still can't use this printer. I was told to take it all apart in which does nothing as I cant access the section that's clogged. I was told by tech support to heat the cleaning rode till its red to try and melt the filament. That just does not work on my end. Also i seem to be doing more damage to the surrounding areas. I am new to using these since I started a new job. I have always sourced out 3D printing out. To all the veterans here is this a common issue? I'm shocked that after 3 weeks tech support really has no idea how to help me. They just keep reseeding the same options to try that don't work. It's cool technology but this is a major design flaw if this process is typical.

[ocelot27]

Yes it's a common issue unless you address the inadequate cooling of the heat sinks. Just do a search for "jam" and you'll see. What filament are you printing? It's more of an issue with long PLA prints - you could switch to PETG or ABS and probably get by.

[Kenos]

Raise3D sent me a few new extruders and I've replaced them but after a print or two I have the same problem. Ive not replaced the extruder 3 times, hot end twice, changed filament brands 3 times, leveled the bed, adjusted the nozzle height and I now again have the same issue. I think that we could have bought 10 of these machines in just lost hours with tech support and fixing it over and over. Are there technicians we can pay to fix this thing? These machines are meant to make my job easier but it's been nothing but a nightmare for me. I really don't feel like replacing this extruder again to just have this problem in a few days.

[Vicky@Raise3D]

The issue might be caused by improper extrusion tension. Has brought it up to our tech team. They will follow up your ticket very soon.

[Stretch]

just came back to see if Raise3d has done good by the customer and updated the extrusion assembly to fix this problem that EVERYONE has... my V2 PRO is sitting in the corner collecting dust because I just refuse to spend the hours to unclog it again. It really is a defect.. Raise3D needs to fix this and make good but it looks like they are just avoiding till probably V3 comes out. Sad.. I've moved on but I really loved the printer when it worked. Although the extruder assembly with the V2 is the worst, absolute worst on the market right now the software is still one of the best. Anyways. Hope they do fix this, ill check back in 6 months again hoping for a miracle.

[zamble]

PLA absorbs water and jams. I moved from a dry climate in New Mexico to Florida and had all sorts of problems till I put the filament in a modified food dehydrator. This has made all the difference in the world!

HIGHLY recommended.
