Topic: i found out why the head was hitting, x cariage is cracked

So my hot end has been hitting the last layer and losing steps.  I had noticed a cracking sound which I thought was the filament coming through the bushing at the back.  It was a hard sound to locate.  It turns out it was the plastic around the linear bearings on the front rod of the x carriage. I came back to find a print going with the head just riding along the top of the print.  The linear bearings were on the complete  opposite ends of the rod.  I have only had the printer a couple of months.  Does anyone know if solidoodle will send me a replacement x carriage?

They seem to be pretty good at keeping their machines running.

I would think so, only costs them 30 cents in material and a buck for the postage.  May take a little bit though.  Can you acetone weld it back together?

I think the main issue, is that the rods on the X-Axis are glued into the Y Carriages, so you can't just replace the carriage itself.

Re: i found out why the head was hitting, x cariage is cracked

EFFalcon is right, the rods are glued into the Y Carriages.  I contacted Solidoodle about this a while back when I crashed my extruder into a part that was cooling by mistake.  They indicated a new assembly would need to be purchased.  It's $150 on their store if memory serves.  The price didn't bother me, but waiting to receive the part would have killed my productivity.

So I created a new X carriage that can be screwed together and posted it a while back: http://www.soliforum.com/topic/699/crashed-extruder/

It has a gap at the front, but it is remains solid.  I've been running it 24 hours a day for over 2 weeks now without issue.

I do think this is a pretty common issue, though.  On another one of my Solidoodles, I noticed that the X carriage had been cracked in the same spot at the factory.  They glued it together before shipping it out.  That said, the glued part has held together well.

Hey Kyle, have you done any updates to that design since you posted it.  Also any chance you could post stls?

I haven't worked on the design any since I posted it.  It's been working fine for me so I haven't bothered.  I just uploaded the STLs into that post.
