Looks good! I am planning on upgrading my mini v1.02 to the V2 and am thinking I will do this and probably the X axis as well when you finish that!

Thank you for your interest in the project! The x ends are done, I haven't built the x carriage for it yet though. It's a little ways out yet.

Having accomplished this, have you considered doubling the build area from stock by running two build plates next to one another, for a y-axis of about 12"? Obviously it would take some hardware replacements but the frame itself doesn't seem like it would limit the possibility. The self-homing of four corners of a square concerns me more not knowing how the machine uses that data.

I have indeed! The stock power supply should drive a doubled bed, and there are other slightly higher wattage power supplies if I find it is insufficient. The mini Rambo board itself will drive it just fine though. I figure I can use a pair of cantilevered offset extensions to extend the frame mounts for longer rails. Potentially with some stabilizing legs if needed. The software and the washer positions will be the easy part. For the bed plate ill have to get some of them custom cut. Ill use an aluminum plate for the base with 2 heaters adhered below. Its in the works up next after the dual belt 9mm taz y axis im currently finishing. Also the last of the mini 2 openbuilds x bits.

I would be interested in that project.

Its still in the works, getting a longer bed baseplate cut or making it myself is the current holdup. I did test two beds in series and they were able to hold at 110c for 15 minutes or so before I shut it down without blowing any fuses or noticibly heating the power supply so it should be viable. The rail part is going to be the easy part.
