Circles offset on X axis

[Pete Laubenstein]

Circle Problem.jpg

Hello all,

I have had an issue, recently, with printing circles. I hope you can see in the image above. If you cannot enlarge the image, please help me figure out how to attach a larger file.

The issue involves the X axis. When the extruder is running -x and then switches to +x, it seems as if there is some lag. It makes the circles look a little like they are flat on the sides.

I had the same issue with my Y axis months ago, but I re-tensioned my belt and the circles were nearly perfect.

Being new to printing, I will try to share as much technical information that I can:

• Printer =

HICTOP Prusa I3 3D Desktop Printer[SOLD ONLY BY HIC Technology] http://www.amazon.com/HICTOP-Technology-Accuracy-Self-assembly-Tridimensional/dp/B00N7I1ZVU/ref=sr_1_9?ie=UTF8&qid=1433187463&sr=8-9&keywords=3d+printer

• MB = MKS Base V1.2
• Software = Repetier
• Runs with Arduino

I have not had any issues with the motor steps before, as I alluded to above. I did try tensioning the x belt, which was indeed lose, but there were no positive effects. I am wondering how I should go about solving this issue. I have read other posts about calibrating the xstep, but I am not quite sure how to do that. I also am not sure if the motor just needs to be replaced.

Other useful info:

- Recently, my x endstop has stopped working and a small handful of times, the motor will continue to move in the -x direction while trying to home. Could this have damaged the motor?
-I checked the x motor and found that the drive's screws were sufficiently tight, so I do not think it is slipping on the motors end of things.

I would appreciate any feedback you all may have, and thank you!

Pete
