With the Z axis extended, the next axis I attempted is the Y axis – just from looking, the X axis is going to require a lot more work.
The Y axis extension definitely outgrows the original frame, and I took the time to get my hands on some STL files for Y extensions.
I found this page to be immensely helpful,
as I ended up mashing up the STLs from two of the participants, Jon Lawrence and kungfuroy together.
While I was looking at these designs, it seems like I should also replace the fishing line with a GT2 belt, as I have been experiencing some precision issues and since the rods were longer, I was going to have to buy new line anyway to accommodate the new rods.
With the addition of belt upgrade, I needed to print the following additional parts;
- rear_bracket.stl from http://www.thingiverse.com/thing:238932
- front_bracket.stl from http://www.thingiverse.com/thing:238932
- MotorPlateYGT2.STL from http://www.thingiverse.com/thing:194586
Luckily these all fit the bed of the Simple(thanks to the creators for creating their parts that can be printed from a Simple!).
Unfortunately, kungfuroy’s designs are for a bowden extruder set up, which is something I’m not prepared to do at the moment, so I ended up taking a model from Jon Lawrence’s design and modifying it so I can mount the extruder on;
ExtendYFront.STL from http://www.thingiverse.com/thing:242185
I used a Sketchup plugin to import the STL into Sketchup and I altered the design so I can mount that against the front_bracket piece with some zip ties.
With this, I’ve now gotten a ridiculous Y axis range, so long that in fact the machine tips over(maybe a bowden extruder upgrade is a good idea after all?)
Also, figure I should also print MotorMountXGT2.STL from http://www.thingiverse.com/thing:194686 for the X axis as well. For the next upgrade.
