Topic: workbench nozzle removal

i just have my solidoodle workbench printer 2 days ago, i know i may do something foolish that make the filament clog into my 2nd extruder, and its so stubborn and don't want to flow out of the nozzle.

i tried put a needle, it take out some but not all.
i tried heat the extruder to the max and then extrude through repieter host, still no result.
i watched lots of youtubes on how to unplug the noozle, i think none of them have the same structure build as the solidoodle workbench,

so is there any video, pictures tutorials on how to unplug solidoodle workbench nozzle and clean them ???
sorry for newbie question... smile

Re: workbench nozzle removal

To my knowledge, you are the first to clog a Workbench. Solidoodle has made many design changes to the new one printers, so it would really help us help you if you can post a few detailed photos of the extruders.
If the Workbench has a PEEK hotend (I think it does), then unscrew the nozzle and let it soak in acetone if it is an ABS clog. For PLA, you will have to hit it with a torch and run a wire through. Sounds like ABS, so focus on the first.

Just keep calm. We have all had to learn this technology, and the forum is filled the people willing to help...we just need more info to help smile

Re: workbench nozzle removal

Clogged my workbench two days ago...   maybe my simple method can help you also.
Heat the extruder up to your normal printing range and use the long end of a 2mm allen wrench to push the material through.  Make sure you hold the bottom of the extruder carriage firmly and push down the filament release.

It depends where you've cut the lead! If it's really close to the bulb of the thermistor, then you might need to get a new one. But if it's some distance from the end, you may be able to just solder it back together.

If you can upload a photo of the broken lead, then we might be able to give more specific advice.

Don't panic, the thermistors are not expensive and are easily available. And from what I hear you have two extruders so won't even be out of action entirely! smile

Re: workbench nozzle removal

Does anyone have a source for a thermistor equivalent to the solidoodle ones? This would be ideal (no firmware change).

If you buy a slightly different type, the resistance:temperature curve can be a bit different, so you'll need to make a very small firmware change so the printer uses the right table. This then involves learning to configure and flash the firmware. While it's a good thing to be able to do, there are some confusing steps, so if we can avoid it it might save you a few headaches!

Re: workbench nozzle removal

yes it could save me lots of headache if someone could help me with the kind of thermistor used on solidoodle workbench.

i got this from the solidoodle website, but what is that means:

The Workbench models use the same Solidoodle motherboard as previous models with the addition of a daughterboard on top to accommodate the extra extruder motor, heater, and thermistor.

from another page:
http://support.solidoodle.com/hc/en-us/ … Solidoodle

Thermistor

80K Ω -90K Ω

EXT TEMP (opposite end of thermistor)

80K Ω -90K Ω

Hot End Heating Element

5.4Ω - 8.1Ω

EXT HEAT (opposite end of heating element)

5.4Ω - 8.1Ω

Print bed connector labeled (BED HEAT)SD2

2.3Ω -3.3Ω

Print bed connector labeled (BED HEAT) SD3 & SD4

1.5Ω -1.9Ω

Re: workbench nozzle removal

I have quite a few thermistors (used from stock SD2 and new from a RUMBA).
If you or anyone else can confirm these would work well for you, I would be happy to send you replacement(s).

I can't say for certain if they did, but if you got a spare sd2 thermistor from AZERATE I know how to make it work in the firmware. I sincerely doubt they changed the thermistor, however.

Re: workbench nozzle removal

also i found this comment on solidoodle 3

We knw that it need to be resistant to hight temperature so the head of the thermistor must be in glass, have a good accurency, have 100Kohm resistant ...

Re: workbench nozzle removal

Here's my thinking, I've done a bit of sleuthing for you.
Please anyone correct me if they feel they have a more tenable solution for navi.

* I've downloaded the solidoodle workbench firmware, and it uses R-T curve 1 (for EPCOS 100k NTC thermistors with a 4.7k pullup) for both extruders. So whatever you get should match this, regardless of what solidoodle actually used, right?
* You can type "EPCOS 100k NTC thermistor" into google, and get many possible links to buy a suitable thermistor, i.e. https://www.google.com/search?q=epcos+1 … thermistor.

I think as a replacement you could buy any of the following:
http://www.mouser.com/ProductDetail/EPC … xCWg%3D%3D
http://www.reprapdiscount.com/electroni … istor.html
http://www.digikey.com/product-search/e … vendor=495
http://www.ebay.com/itm/251585475244/

This is the standard thermistor type for reprap printers, so there's plenty of them out there marketed as "reprap thermistor" - most should be pretty acceptable. This should be good enough to get you going again, I hope it's of help.

Re: workbench nozzle removal

I managed to buy e3d v6 hot ends with boden add ons, so i think they come with thermistors, i also bought extra thermistors in case something wrong happened

thx for all your support

Re: workbench nozzle removal

Haha super! Enjoy those E3D's, will be a bit of fun installing and getting them going, but if you search a bit on the web (and the E3D website) you'll find plenty of detailed instructions on how it's done.

Make sure you update the firmware to use thermistor table 5 and set the maximum hot end temp to at least 300C for both extruders. Enjoy!
