Dial Indicator mount for Up 3d printer by Bigrinner Sep 20, 2012

Description

This is a simple mount to attach a dial gauge or dial indicator onto an UP! printer where the print head would normally attach. This simple thing is being posted as an idea for others to use on different machines. The UP! head only uses one screw so this is an easy swap out to verify platform level-ness and flatness too.

I am still a little new to this myself, but it seems that the raft helps level the Print surface as well. The raft layers will be squished on some places and have minor gaps in other places do to building on unlevel platforms. The bigger problem seems to be a warped platform. The warped platform cannot be adjusted to correct this. You have to replace a warped platform.

So it seems you only need to be level enough for your raft to be able to make the fine correction s

good idea for keeping quality of prints high.  i tried this and couldn't really get it as flat as i wanted.
i came pretty close to +/- .05" throughout my platform, which is more than i wanted considering a span of .010" is .25mm, which is about a whole layer.

I use the gyro on my iphone as a level. pretty accurate too.

Instructions

I am using a dial indicator from Harbor Freight (I'm amazed how much I use this thing). It simply friction fits into the rectangular slot. I tapped the round hole before attaching it to the UP!. I put the hole on both sides of the block incase I should accidently strip out one side. I had the rectangular hole go all the way thru incase the friction fit was too strong, I could push it out from the back side of the hole.

Update! For all my Up! friends (that's people on this site that use an Up!) Up! gave us a Christmas gift this past year. A new software release version 1.18. it has extra settings that imply correcting for the lack of flatness and levelness of the platform. See the new screen shot of the way the program learns this information (its a semi-manual operation).

Let me know of any successes out there.

This is a great idea! 
I have had my dial indicator sitting next to my machine, brainstorming a
bunch of crazy ideas to get it mounted.  Keeping
it simple is a much better idea, KISS principle :)
