I've been having a fairly minor issue with keeping the bed level. The left front corner, X0 Y220, appears to be a fraction of a millimeter high or low depending on temperature. I suspect the issue is most likely the H-frame Y carriage assembly.

Have any of you updated to a better Y carriage?
 
I did, sorry, thought I had updated my build thread, but apparently I only added some links to what I used.

I used this plate (sorry, appear to be sold out, but may email and see if they will have more soon)...https://reprapchampion.com/collecti...rusa-i3-reprap-3d-printer?variant=14046987526

The above plate requires spacers to clear the motor and a new belt connector: http://www.thingiverse.com/thing:1698328 & http://www.thingiverse.com/thing:863408

Someone did post a carriage plate on thingiverse, may be able to use it to cut out on your cnc or at least mark all the drill points using a vbit on some aluminum plate, it has a cut-out for the motor, but wouldn't have to do that if you used the spacers above, you do lose about 12mm in height though... http://www.thingiverse.com/thing:2063292

BTW. it pretty well eliminated issues I was having with bed leveling. I still have a couple of high spots, but seems to go away if I change the glass, so it may not be perfectly flat.

Thanks for the links, Darren. I looked through your thread but must have jumped past that post - my brain is old and moldy! I checked all other sources of the same plate and the only one showing availability is in China, so I'll wait.

Cutting a plate on my CNC is an interesting option. I don't really like the design on Thingiverse. I could model one in VCarve based on the dimensions of the Reprap V2.
 
I really don't think you'd need to "cut" one on the cnc, maybe just mark the holes using a v-bit and finish it on your drill press. With that model on thingiverse, other than where the motor cut out is, it's pretty much just a square plate all other cut-outs are aestheti. You could cut out the motor using the band saw or jigsaw, or simply just leave it whole and do the riser blocks like I did, seems like that cut-out for the motor would be introducing a problem like you have now anyway.
 
All good points, Darren. The carriage doesn't have to be "pretty". After all, it's covered by the heat bed. I like the idea about using the CNC to mark the locations and finishing on the drill press.

Another thought was that if you're using auto-leveling, you probably can do away with the springs and use shorter spacers between the carriage and bed to gain some of the space back used up by the bearing spacers.

I did away with the springs when I added my glass holders on the corners of the bed. It was easier to level the bed manually with the springs out of the way. Now I have auto-leveling, so that takes care of most issues, with the exception of what seems to be happening with temperature changes.
