I take that back.  It did get up to 213C.  When do you check it and where exactly do you measure?

Hittinbottom:

It sounds like your head is still clogged. Try to heat up the straight pin until red hot and stick in hole while it is in load mode (saying to push on filament), keep pushing down but not up too much as it is hot and will make more of a mess in the tube above heat head. Another method is first unplug cube, disassemble fan and pulley, place a drop of sewing machine oil in tube, then heat up the pin again and slightly insert in tube, let it cool, then twist and pull plastic upward. It can can take many times to clear out! Good luck!

You are the man Dan!!! Got this thing working after only a couple hours of adjusting and cleaning out the head. I am using matterhacker black PLA and it seems to be very much compared to the cube filament. I would like to add a switch like yours but can you give a little more detail on how to do it?

Here is a picture of my setup. Thanks Dan!!!!

A really crap picture of how it's done. nothing special here, just a basic switch.  (Note I used a momentary push button on mine- it doesnt matter what you use as long as you remember to release the switch after the firmware has checked the cartridge.  With a momentary switch, the button is released when your hand is - therefore no forgetting - remove your hand and the switch is open, push it in and the switch is closed, completing the connection).

Hmmm.  way too cold.  170 is the quoted extrusion temp of most PLAs I have used.  Perhaps my current 100K epcos thermister is out, but If I try to extrude at 170 degrees with the new setup, the extruder skips steps and also slips on the filament, eventually the extruder becomes blocked.  If your extruder is hot enough AND the extuder is ROUGHLY aligned right (it doesnt need to be perfect), it should have no problem pushing through filament.  To measure, I just taped (using kapton) my thermocouple to the brass part of the hotendand ran it through a filament load process.  Mine got to roughly 210 degrees before it started pulling through filament. 

I wish I took some pictures of this before I tore apart the existing setup.  Sorry about that.  Regardless my factory setup worked fine with ANY **** filament I would use.  But the temp of mine measured 210 with PLA.  Knowing 3D printers and their components, I wouldnt be suprised if your printer runs cooler than mine.  If I take 3 thermisters and 3 heater cartridges - all of the same type, there is definitely considerable variation between them if used in the same setup.   These electronics are not accurate unless they have been calibrated.  Perhaps yours wasn't before it left the factory.

Saying all this, PLA melts and extrudes OK at 170 - just not as nearly as well as PLA at 210. In my experience.

I believe temperature settings are stored in the .cube file anyway.  Looking at some of the recent posts, it appears you may be able to compensate for your particular setup by increasing the temp in your sliced files.

I would like to add an additional switch to toggle back and forth between PLA and ABS chips along with the momentary switch. I already screwed up one chip trying to dissect it from the case, so I do not want to screw up any more chips (even though that one was a freebie anyway), any suggestions would be appreciated.

the chip should fall out of the filament spool case when the case is unclipped.  You should find clips all along the perimeter of the casing, just stick a screw driver in there.   I really hope you're not dissecting the chip itself.

Yes I meant the case, one time I had the crappy cube filament crack inside so I had to disassemble case. When I put all back including chip in place cube did not recognize chip, so I am concerned about paying $50 bucks for nothing.

Anyways, I would like to print some kind of box that will contain the swiches and chips that can be easily removed from the contacts. Here is a wiring diagram of what I was thinking? Is this possible and do I use DPDT or DPST switch? Thanks in advance.

It got up to 213C.  What type of text editor are you guys using to be able to open the .cube file?

The connectors will break off eventually anyway, so wiring something else is going to be necessary..DPDT or ST???  I have no idea.  Well beyond my level of understanding.  Do they not do the same thing?  I would think whatever you need may need 4 inputs though? Perhaps a 3 position switch returing to open circuit when released?

Sorry man.  I'm an electro hack.

That is even a better idea using a 3 position DPDT switch, that way I can eliminate the momentary switch... I will update when designed and printed! Thanks.

Im fairly new to the cube and 3d printing for that matter i tried using some bulk filament but i hear the click sound. I see people saying they adjust the pulley or the head but im not really sure how to go about either. If anyone could post pictures of where im supposed to adjust stuff it would be extremely helpful to me.

Remove plastic cover of the print head.  Then in the front you will see the 7mm bolt.  Loosen that bolt with the included wrench and adjust it while you are printing.  I don't have the machine front of me but i can send you some pics by mid week.  Maybe sombody else could upload an image for you.

Honestly that would be great. Thank you  :)
Edit: Now it has a small piece of filament stuck in it and i cant push it out.....great

Sweet thanks Vicm. That works like a charm. Well a charm with some force. Hopefully I can get the filament to feed through soon. After I figure out were the pulley is.
