It sounds like you need to adjust your z end stop switch so that your nozzle homes to the right height above the platform (about .1mm or so)
-
Set the Target temp to 200 and watch the current temperature rise, if it gets to 210 turn your machine off and check.
If the current temp doesn't move but you can feel the heater block warming up then turn your machine off and check.
When it gets to 200 set the motor speed to 500 and click on forward, the extruder motor should turn.

Hi Sam
Which firmware are you using, which version of RepG and which software to slice your GCode?
Did the smoke come out of the nozzle or above that.
Can you drive the extruder from the RepG control panel?
-
im also interested.
edit: damn it just read it, looks like the orders been sent ages ago.
want more people interested? try emailing around the australian hackerspaces list. im pretty sure there would be a few from hackerspace-adelaide that would also be interested
We never sent the order once it went out of stock.

got a stl file for thingiverse > generated code (skeinforge 35, pla-ultimaker-failsafe) for some reason i cannot use Skeinforge 40 as the extruder motor wont start up.
And voila, i have a box inside print (which is has much smooter surface than the print i'd like to have)
Is there a way to reset machine or does it have some files written in system preferences which i can delete?
Not sure as I don't use skeinforge.
I think you should go down the path of getting Cura.
Better easier slicing.
Easier, better setting up of firmware.
It will probably fix your problems and also make for better printing besides.
Let us know how you go.

That's wierd alright. What was your process from having the stl file to printing?
-
Yep, that's right.

Latest Marlin I think. Uploaded through your builder. Software endstops enabled and Endstops only for homing. How does this affect it?
It means you can move trough the endstop with G1 commands. If you don't have "Endstops only for homing" enabled, then you cannot move beyond the endstop. This is the default in the Cura firmware, to protect your machine.
This means that with the default Cura firmware, you cannot adjust the Z in the start code if your bed is too low, only when it is too high.
I see, so unless your height is adjusted too close via the stops or you have the corner cut off you can't do it.
In my case I have the corner of the platform cut off and my setting is G92 Z-0.48
I adjust this up or down by +/-0.04 or +/-0.08 to give a tighter or looser start
Even without a cut off corner you could probably adjust your initial homing to about -0.2 with the screw or whatever and do it through GCode from there.
I'm a definite fan of this method, I don't need to adjust it often anyway. I have an optical endstop for Z too now so maybe that is giving a more consistent homing as well.

The Z0.0 referrers to the "G92 X0 Y0 Z0 E0"
It changes the actual "zero point" compared to the end stop, right now it says "0" is exactly the endstop. With Z1.0 you say that the endstop is 1.0mm above the bed. However, I'm not sure if that will work correctly...
It works great. I've been only adjusting my bed height there for a while now. I don't use a screw adjustment anymore. It's easier and more accurate/consistent. Plus you get to see the actual variations in height that happen.
But do you use a firmware that always stops on endstops or only when homing?

There's not a G92 code followed by a Z0 is there?

Sounds like a good idea Joergen

You may need this http://www.thingiverse.com/thing:11864. Though before that, try cutting off about 15mm off the end of the Bowden tube, making sure there is no plastic in the top of the peek piece and follow instructions as per other posts or Wiki to get the Bowden tube back in place with no gap between it and where it sits inside the peek.

Hi William
Just push it in all the way and pull back.
The small round piece should come back a bit with it.
Don't push the small round piece back down, that will release it again.

Hi
Not good to run two 120W 19V power supplies in parallel
Not sure about your Thermistor situation
-
I agree with I Robert I. Also, are you using Marlin for firmware? It has very good temperature regulation.

Here is the result of my weekend:

I had to print it immediately after I found it on thingiverse, I'm a huge fan of this model!
Awesome print. Well done.

Hi
Can you extrude from control panel in RapG?
For Netfabb GCode you need to put an M92 E14 command in the header. Did you know about this.
-
Hi
This is usually caused by belt tension, or lack of. Check all 6 belts and tighten where necessary.

That's great almi
good luck

What's the green knob on the top for Daid?
Looks like a manual crank for the Z axis. That used to be a common trick with the old repraps (before the switch to two Z axis steppers) When the outline of the part is being printed you manually crank on the z if it's not adhering properly. At least that's what I've seen some of the guys at the hackerspace doing

Thanks armstrom

Nice print
I go for 8 sides point upwards for horizontal holes.
These have a 22.5 degree overhang at the worst spot and are closer to a circle.
Bowden tube pushing itself out

Try to clamp something around the Bowden Tube above the wood block and then hold this clamped item down with cable ties while the Bowden tube is pushed into it's place.
Good luck.
