I have been trying to print with this printer and getting very strange results. I found that the left side slide seems to have only one "bearing" in it so the platform has a bit of a bend in it and the underside rail hits a small protrusion in the rail at times hitting hard enough to stop the printer or make the job fail in some way. Then tonight after working out I could work around this issue by placing the model in one corner about an hour into printing the slide bearing that carries the print head from left to right had both bearings on one side come out tilting the print head. I can't see how they are supposed to be kept in place either. It would also be no small task to send it to you guys as I am in Malaysia. Help please.
