You either have your e-steps calibration wrong or your z-steps.
What kind of lead screws do you have? The pitch is important to know.
Also the diameter of the extruder drive gear to estimate the right e-steps.
You can see calibration guides here
The other problem might be, binding on the smooth rods from very tight x-carrier belt.
Or your z-stepper current is too low and skips steps

I just got my new Prusa i3 to print except now this is my issue. It prints perfectly from the start, but then after about 30-40 layers the Z axis will rise, but not high enough and the hot end begins to dig into the piece, and then with each subsequent layer it just gets worse and worse. I've tried just leaving it to run like this for a while but it never fixes itself. It looks perfect up until t

I haven't tried it, but Andrew spent some time looking at the Greg's/Wade extruders:
What problems are you having with the MK8? I just got mine going and it seems to be great. In fact, I just ordered a second one to go dual Can't beat the value at under 30 bucks.
I am having an issue where the motor is not providing enough torque to push the filament through. So it basically pushe

I just got a Prusa i3 from Geeetech which came with a MK8 extruder which I have been having many problems with. I would like to get a "Greg's Wade Extruder", so I looked that up on Ebay but there are so many different ones and none of them seem to come with a hot end of any sort. I have absolutely no idea which hot end to get or what will fit so I need some help deciding on what I need to buy.

If you set the temperatures in the slicer it gets incorporated into the gcode file and will override your manual settings once the print starts. If you set the temperatures to zero in the slicer, your manual settings should work.
Ahh thank you, that fixes that problem. Now the extruder still can't get quite up to 230 but I'm going to get a better extruder to fix that.

Wow really? I did not know that at all, I got this printer planning to use primarily ABS, and that is all I have, would I need to get a new extruder then? And if I do how can I remove the 200 degree limit? Also what is PID tuning?

This is the printer I have:
I have everything assembled and moving but I can't print because of this.
So, first I preheat the extruder to 230, and the extruder only heats up to around 220 and stays there, but I start the print anyway. But when I do that the target temp of the extruder immediately gets set to 200. Both Pronterface, and the LCD panel on the printer are set to 230, and I can't fin

I have tried other baud rates, 250000 is correct for the Marlin firmware that I am using.

I am using Ubuntu 14.04.1 and I'm trying to get Pronterface to connect to the printer. The serial port that it defaults to is /dev/ttyACM0 I believe (could be slightly wrong, I do not have the printer with me right now to see. It is for a school project). I have my baudrate set to 250000 which is correct for Marlin which I have loaded onto the Arduino. I open Pronterface with sudo ./pronterface.
