Z Bot!

thingiverse

Thank you for your interest in the rework of the original D-Bot, The Z-Bot. The Z-Bot is basically an upgraded version of the D-Bot. I replaced all the axes with a 3-Wheel system and added a second rail for bed support. Approximately two weeks before uploading this design, I started working on a 3 wheel carriage for my D-Bot printer. After having to recreate numerous parts in CAD to facilitate this new design, I decided to remake all parts from the original D-Bot along with several different parts that I use on my printer. In the Zip file you will find three folders. One has all of the original .stl files that the parts in the 4 wheel folder were made from. The 4 wheel folder contains all of the parts for the original D-Bot in .stl, .step, and .sldprt formats. In the 3 Wheel folder are all of the parts needed to make it. Most of them are similar but some of them are significantly different. Pay close attention to the leading numbers as this is how many are required to produce the Z-Bot. All build instructions are the same as the D-Bot, except for the build bed. I dislike the idea of a cantilevered bed and had several problems with the far edge wobbling on me so I added guides to that side as well. You will need another piece of V-Slot rail at 448mm. Install it just like the opposing side. Once installed on the frame, make sure it slides all the way without any resistance. If there is any resistance, loosen the bolts for the motor mounts or idlers on both sides and continue. Once you have free range of motion with the build bed, the bolts can be retightened. This is the best way I've found to ensure that your frame is square to the bed. The two files in the main folder are included in the Zip file. These parts were the inspiration for this design, so I figured I might as well add them.
