Troubleshooting  - 
 
Hi everyone, I started to get a mintemp error on my E3D hotend so I replaced the thermistor with another 100K Semilec NTC thermistor.  Now I am getting a MAXTEMP with a reported temperature of 683 degrees Celsius as soon as I turn it on.  Anyone have any ideas what would cause it to report that high of a temp.

It was a short. Thanks for the help.

ok, I have a question before I go and put my printer in  a box.  I have been printing on the white ABS that came with the printer.  I ordered more when I ordered the printer but it has yet to arrive, but that is a different subject.

I purchased some ABS because I am about out of what came with the printer.  This new ABS keeps curling up at the edges and sometimes will even break loose.

I am using painters tape on the bed.  I replaced the tape to see if it made any difference and same thing.  I do not have this problem with what came with the printer.

I was reading online that some people have had luck with putting it in a box or putting cardboard or plastic around the printer so the print area stays warm.

Has anyone done that?  Does it help?  Any other ideas for the ABS to get it to stick?

The ABS is from Octave if that helps any.  I ordered 2 different brands, the other brand is much worse.  I do not think it is ABS as it says, smells like used motor oil when it prints, will not stick at all, is very gooey and is not stiff when it cools.

I would get a glass plate and use abs juice, this will solve almost all your curling issues.

I have a new e3d hotend on the way but I need a way to mount it so I downloaded a mount and was going to print it.  I had to take off the RB hotend and clear it out again.  When I did that I must have touched the thermisor because now I am getting the MINTEMP error again.

Does anyone know if the thermistor is an off the shelf product that I can get somewhere like mouser?

Or, will anyone here print a mount for me if I pay you for it?  I should have the new hotend in the next week or so and it comes with a thermistor.

I got it worked out. I ordered some new thermistors, fixed that and cleaned the original hot end again and it lasted long enough to print the mount. I almost have the hotend mounted. I have one screw I need to sink to get the motor to sit right and I will be done.

Software (Open Source)  - 
 
I have been playing with sketchup and I am not sure if it is the right software for what I am trying to do.  I am trying to make enclosures for PC Boards and want to prototype them before I send then to the enclosure manufacturer.  I know the exact x and y coordinates for the holes I need but I can not see an easy way in sketchup to say I need this piece I just drew to be centered at a specific x and y coordinate.

Am I missing something or is there better software for doing drawings that are more mechanical in nature than creative in nature?

Parametric modeling is what you need.  Haven't tried DesignSpark - will do that.  I use Geomagic Design which is now Cubify Design.  For the price, I highly recommend it.  Autodesk Inventor is far more expensive.

so I got the replacement thermistor and printed the first sample part last night.  I decided to go a little bigger today and print a raspberry pie case.  About an hour and a half in and it sounds like the extruder tip is hitting the honeycomb structure as it moves.  Is there an adjustment that needs to be made?

There is an alignment topic on the Wiki for the Z axis alignment to prevent binding.

I am not sure if this is the proper category for this question but it did not seem to fit anywhere else...

I have been using 123design from adobe to create 3d files.  Is there better software for designing in 3D that is commonly used?  I have seen people using Solidworks which I have not heard of until recently.  

I would appreciate opinions from those that have some more experience in designing in 3D.

+Faye Salwin That's interesting.  I just looked at a tutorial on OpenSCAD. Certainly a way to get very precise alignment of objects.  Typing in object parameters is a very abstract approach though.  Just like any language, though, if I don't use it often, there is a learning curve every time I have to pick it up again.

Hi again. I got the e3D hotend on the rigidbbot tonight. I noticed the temperature bounces around a bit. I had it set at 230 and it went from 223 to 238 back and forth constantly. Is that normal for that hotend?

One thing that I had hoped the new hotend would fix is the material feeding problems I am having. I thought the old hotend was clogging. Even with the e3d end I have problems. No tip, feed 100 mm of material and 100mm feeds. With the tip on and at temperature if I feed 1mm at a time it will feed a little bit but not 1mm. It is slipping and not grabbing hold of the material very well. If I put just a push the material just a little bit it feeds just fine as needed.

I noticed on my first test print with the new hotend that it was missing or had thin material. I then helped it out by pushing the material slightly and it started to print beautifully. Is this a common problem? If so, is there a common fix?

Motor turns, but does not move filament?  Is your hobbed pulley grinding into the filament (likely due to parts being mis-aligned)?  Is it even moving (maybe grub screw came loose)?

Ok, so I need some advice on a new hotend.  I am looking at the E3D V6 Hotend.  How do you mount that onto the rigidbot? Also there are options for the feed type that I do not understand, None, Direct Feed or Bowden Feed.

Can someone give me some learning :)

If you really worry, I believe you can send the files to someone and have them machine it out of aluminum... Tom's mount is probably the simplest to do in aluminum.

I am having a problem that I have seen mentioned on here before.  The material is not being fed in fast enough.  If I put some pressure and try to help it feed it does get better.

It seems that the material is being held tightly by the gear in the extruder.

I am thinking that maybe the extruder head is clogged?  I took the extruder apart to make sure the material was going through the gear properly and that all looks fine.

Any other thoughts or is the extruder tip just getting clogged, any advice on how to not get it clogged?

I finally got the thermistor replaced and printing my first item.  The Z axis screws apparently need some oil because they screech like fingernails on a chalkboard from time to time.  Is there any specific oil that is recommended?
