Thanks for the reply, As far as pricing is concerned, I don't want to put a number out there to have people become upset if it does not come in at that price. But less than what we are currently paying, otherwise why waste my time. What I can tell you is that currently it costs $10/lb for natural and $12/lb for colored plus shipping, customs, duty, etc. Right now it costs $50 plus $27 shippingby Sublime - Canada, Vancouver RepRap User Group

Since no one has responded does this mean people want to pay more for filament? If so instead of offering a cheaper alternative I could offer HIGHER prices. If you do want a CHEAPER supplier PLEASE speak up, I am not asking for money. I just want to know how many people are currently paying way to much to get their filament.

Ok I made a picture to explain the problem. DO NOT take this as me saying the hotend pictured has this problem. I just used the picture on the page you linked. Since you removed the part that is supposed to keep these two parts tightly together it could be causing the issue. My method of preventing this in my design is to drill it out after assembly but before putting the tip on. I then heby Sublime - Huxley
Acetone will only work for ABS. The only time I ever had jams was because the edge between the heater barrel and thermal barrier was not perfect.

I can't comment on Techzones products other than to say a large portion of the problems people post about on the RepRap forums involve their products. Mendel, electronics, etc. So either it is Techzone or the people who buy products from them expect to much.

The effect of increasing this is to cause the lines that create the infill to be further apart. So if your solid base infill is sparse decrease the value. If solid infill aby Sublime - Skeinforge
Right now your extruding to much material. If your layer height is .4mm and the width is set to 1.5 you should have an extrusion .4mm high by .6mm wide (.4 x 1.5 = .6mm) But it sounds/looks like the extrusion is more like .72mm wide so you either need to tell skeinforge that is what you are using by setting the width over height to 1.8 (.4 x 1.8 = .72mm) OR Fix the E steps per mm to match thby Sublime - Skeinforge

I believe you could change a number of different variables to get the same results. The key to learning what they all do is printing 10mm cubes and changing one setting at a time to see how it effects the build. I printed 50 10mm cubes to get usable parts with correct dimensions, then another 5lbs of stuff to get my machine calibrated to what I feel is near perfect. Most if not all of the stuff wby Sublime - Skeinforge
I wasn't going to say anything because Nophead gave the the answer early on. You need to reduce the flow rate or increase your width over height to compensate for the extra material coming out of the nozzle. It also may just be that your nozzles face it not parallel to the build surface which means that one edge of the very tip is dragging below the extrusion hole which causes a rough finish.by Sublime - Skeinforge

First off I think you mean derivative, a clone would be exactly the same as the original. The Ultimaker has 210 x210 x210 and the height should not be all that hard to change. It also has provisions for dual extruders on the driver board and it fast.by Sublime - General
Z won't be the same as the rest but now that its close you can use the control panel to jog it 10mm while measuring its movement then use this to calculate the correct value and then retest and do it again until its perfect.by Sublime - General

Not sure why E is not working, you could try sending the command from Repsnappers Gcode panel by typing in G1 E20 F600 just to see if it is a ReplicatorG issue or firmware issue. The Other problems you are having with the Z may be a Z_steps_per_mm issue in the firmware.by Sublime - General
Ramps 1.3 has 5 drivers two for extruders, have you tried connecting the extruder up to the other one? If you look in pins.h of sprinter it has a RAMPS section that has all the pin assignments if you just want to confirm which it uses for E. It also has a define for RAMPS 1.3 because the default is for 1.2 and that may need to be changed.by Sublime - General
RepRap changes at such a fast rate it would be a full time job to try and keep up with just one variation of machine. And the beautiful Prusa manual is made using sketchup to export the pictures of the model by a dedicated individual.by Sublime - General
The reason it moves in one direction only could be your soft limits which would allow you to move forward and back to the same spot but not back further. But more likely is you need to invert your endstops in the firmware. The extruder may be just that you need to enter a high value for the rpm then click forward. For the heater just type in a temperature and wait a few seconds to see if the grby Sublime - General
The reason you had a hard time with the pin numbers is because Teacup uses the port number of the atmega2560 not the arduino pin number. Sorry I should have said something first. You would need to look at the data sheet for the atmega2560 to find the port number or look at the file arduino_1280.h in the teacup folder it has all the pins listed.by Sublime - General
The truth is that most firmwares don't like having the job sent to them from ReplicatorG. You can use ReplicatorG to create the Gcode and then send it to the machine using Pronterface or a serial terminal which work every time. The thing you should know is that ReplicatorG is just an interface to skeinforge and you will have to learn skeinforge to use it. The default profiles are for Makerbots anby Sublime - General
RAMPS 1.3 has been out for less than a month. You can ask Johnny at Ultimachine to make a config for it the same way he did with sprinter. Otherwise it is up to you or one of the other people who just purchased a 1.3 to make and submit it to the Teacup team..

Teacup does not have a Config for RAMPS 1.3 so you will have to change the pinouts in the config or use sprinter which has a Config for RAMPS 1.3by Sublime - General
Sprinter currently has a minimum feedrate, meaning it accelerates from this speed and decelerates back to this speed. Not zero to max to zero to max to zero, but rather minimum to max to minimum to max ....... The minimum should then be set to the speed your machine can run at without acceleration and no issues. So then from the minimum is when we start implementing the acceleration, but a reasonby Sublime - General
I totally understand and hope I am not coming across gruff. The videos are on there own page at the top of my blog. It does not look like it stops entirely it because it accelerates at about 500mm/s^2 when running at 120mm/s print 200mm/s travel which gives it the appearance of constant movement. When I print at 50mm/s travel 85mm/s I accelerate at 1500mm/s^2 which is just enough to deal withby Sublime - General
