Dial Indicator Mount for Solidoodle 2 by ianjohnson Aug 7, 2012

Description

A mount for holding a dial indicator on to the front of the Solidoodle's extruder. It fits tightly over some of the bolts on the extruder and uses magnets to hold it in place.

i made this not sure if it will fit all dial indicators, but worth a try
This fits an SD3 if you push the lower 2 magnets flush with the _front_ of the print, and the upper two flush with the back. The new extruder has the lower screws facing foward so you need a little more clearance. A little cyanoacrylate (super glue) holds the magnets in just fine.

As for the dial indicator, mine came with a flange mount, and a flush plastic back you can replace the metal flange back with (just remove the 4 screws and swap the back). There also seemed to be a USB port on mine. Anybody work out if it can be automated remotely? It would be interesting to move the bed and measure it in real time to plot the bed flatness and level as you move the adjustment screws.
To zimmer: the lug back probably unscrews, mine did. (Mine's a Grizzly analog dial caliper, also from Harbor Freight but bought years ago for my table saw).  It'll leave the innards exposed but I bet we could print a flat round back to protect them.  Make it a little thick and inset a magnet into it as well (make sure polarities are lined up the way you want for the mag on the back and the one on Dialmount2! ;)

Instructions

You will need 1/4"x1/4" rare earth magnets like these - http://www.amazon.com/gp/product/B000SQK2JK/ref=oh_details_o02_s00_i01

The indicator mount is made to fit a 3/8" shaft like this one- http://www.amazon.com/gp/product/B006YD7G36/ref=oh_details_o02_s00_i00

It shouldn't be hard to alter the hole to fit whatever indicator you might want to use.

Print the mount and push the magnets into the holes on the face of it as far as possible. Glue the tab of the indicator holder on to the face of the mount between two of the magnets.

Set the dial indicator in the mount and slide it onto the bolts of the extruder and push it as flush to the acrylic as possible.

I got a dial indicator from harbor freight today. The shaft size seems right, but there is a big mounting flange on the back that is in the way.

The indicater is a good price, I think I'll redesign the dialmount part to allow for this guage.

If you look at the pictures on amazon, you'll see the two different styles.. the harbor freight one looks like the one with that big thing in the back.

I suppose I could cut it off too.

I noticed that Solidoodles shipping now have the bolts that hold the extruder on the carriage turned around so the ends stick out the front. The mount will probably still work if you leave the magnets off the bottom 2 holes, but the fit might not be so snug.
Thanks for uploading this, Ian. Will most certainly be one of my first prints.
