Well a pendulum makes obvious sense. I got the back plate a little more square with the print bed with much better results!
Thanks a bunch,

Sounds like an issue I had when first starting...

Hello all,
I own a self built Prusa Mendel i3. Sadly, while my prints are coming out looking great, they are also coming out skewed at a slight angle of about 5 degrees off of perpendicular normal of the bed. This skew is consistent, causing cubes to come out as Rhombohedrons.
So here are a few reasons I think may be causing this:
1) The y-axis is slipping/crashing. (this does not appear

Update:
The vendor replaced the black casing part for my hot end. I'm up and printing again!

Hello All,
I had finally got my Prusa Mendel I3 running smoothly... wow what a labor of love (and six months). But last night, I noticed that the bass hot end was seated at an angle in the plastic casing. I unscrewed the hot end, but the casing is cracking when I try to screw the hot-end back in and the thread in the casing is permanently angled now. So now I am left with a few questions.

Hi All,
I have a Prusa Mendel i3. I have been having issue with larger items I'm trying to print coming loose mid print (at random times, see attached picture). I need some suggestions. I have a glass bed with kapton tape (completely smooth) covering it and am printing with ABS right now.
Thank You,
Christopher

Hello All,
I am still experiencing this issue. Any more input would be very much appreciated. With regards to the last post, I slowed down my max motor speed and I am now able to trigger the endstops with out slippage. This issue really seams to be centered around the fact that the printer loses track of where it really is and prints in random spots.
Best Regards,
Christopher

After further work on it I do notice that the Motors slip when they get to the Endstops, but are eventually able to trigger the endstop. Is this an issue?

Oh this is a Prusa Mendel i3 with Arduino 2560 Mega and Ramps 1.4.

Thanks for the reply.
I just tried a dry print to see if it was the printed filament knocking the extrude around. It seems to be doing this "drift" with anything being printed. I am trying my best to calibrate the thing right now to prevent any skipped steps.

Hi All,
I will start off this thread by saying that I have not finished my calibrations yet, but I don't know that the behavior I'm experiencing is a calibration issue. The issue is basically that the printer is not printing as if there is a Z axis, even though I can manually move the Z-axis through Pronterface/Repetier-Host. It looks like others have had this problem before, but my issue has

A final update:
The end stops where working. I found this out by sending the M116 command, but under manual control I had the firmware set up so that it didn't prevent me from moving "past" the end stops.
Thanks for all the help!

Thank you for the replies!
Currently I am with out my 3D printer, but I would like to work on simulate connecting the printer up to auto print (for example ). I need software that will automatically do what the Repetier-Host accomplishes manually. If this means writing the code then I am happy to get to work on it, but I require a test environment.
Here are my requirements for:

Hi All,
I wasn't sure where to post this question, so hopefully it's appropriate for the General Discussion. I am basically trying to set up a test environment where I can simulate sending a print job to a virtualized Arduino that is connected to a virtual 3D printer. The simulation of an Arduino looks straight forward (http://arduinosim.sourceforge.net/ looks like a solution), but get a virtu

Hi All,
I just wanted to give a quick update on this issue, sorry for the delay, but I was out of town. So on a hunch from what you said Bob, I switched the inner wires leading to the motors and they seem to work now. I'm not convinced to end stops are working, but I will let you know later tonight.
Best Regards

Hi Bob,
I have sent and email to the vendor to get more information about these motors. They were advertised as NEMA 17, but I won't know that for sure until I can find a spec sheet I guess.
This probably won't help much, but I have include a picture of the motor label side mounted on the x-axis. There is a quarter behind it for size reference.
Thank You

I have now also tested Jumping the three sets of pins on the Ramps board under the StepStick. This seems to have no effect except to cause less movement in the motors.

I have attached pictures to this post to help in answering my question. I have only attached the x-axis stepstick and end stop to simplify the task. This may not mesh well with the Firmware...
Some things that would help:
How do I look up the Vref on my motors so I know the correct voltage to set on the trimpots?
How do I identify for the Honeywell V15T16-cz300A06-K switch which connection i

Hello,
II am having issues with the motors and after diligently searching for an answer and giving many solutions a try, I have not been able to fixed the issue. I am using an Arduino Mega 2560 with a Ramps 1.4 board on top of it.
