Mendelmax Upgrades

Before Ive even finished my Mendelmax I am upgrading parts of it!

The main reason for this is that I have recently ordered a set of Precision Linear Shafting for MendelMax. These come with 10mm Z shafts, vs the 8mm I was expecting. So a few parts need upgrading.





New 10mm Z ends http://www.thingiverse.com/thing:16298

New lower 10mm Z ends http://www.thingiverse.com/thing:17267 


New 10mm end stop holders, these didn't exists, so I made my own.

3 things, silica gel,mendelmax and sprinter

I use Silica Gel in my large container where I store my PLA, to absorb any moisture, the issue with this is it is use once. The stuff I have starts off yellow and turn dark blue when used. I decided in a stroke of 'madness' that I would try and remove the water from the used silica gel, by putting them in the microwave, to my surprise after two bursts of 1min on high, the Silica Gel is yellow again! I dripped a drop of water onto one of the crystals and it tuned blue again, so it still works.  The Crystals are not as nice and round as they started out, most have deteriorated and cracked, but should extend the life 2-3 times.  I have no way to determine how effective the recycled stuff is in comparison to the original.

Anyone thinking about making a Mendelmax, they have now opened up a online shop http://store.mendelmax.com/ This makes getting the t-slot so much easyer for us New Zealanders. Still not particularly cheap with shipping... But better than anything local thus far.



I recently wanted to re-tune/verify my reprap e-steps. In sprinter is a very nice command M92 this enables you to override the value store in firmware for how many steps per mm for any axis including E. This enables you to set a new value and test without having to re-flash your firmware every time.  This is very very useful!.  This is only designed to find your perfect steps per mm value, you should still flash this value after you have worked it out. The M92 command is forgotten after a reset.

Lots of reprap plastics

I've been somewhat over whelmed with orders for parts... This has been keeping me quite busy
 


4 Sets of Prusa Iteration V2. The blacks not quite done, but one of the other sets is leaving and I wanted this picture.
