Alright – its a long time since the last Stablebot update! Since I’ll be presenting on the stablebot, at VERRF, I want to do a writeup on what it is and what it’s not! Without further ado - What is the Stablebot Core? The Stablebot Core intends to be a scalable motion platform that utilizes E3D’s toolchanging specifications to use tools. Primary uses are :3D Printing with Light milling (in the form of ASMBL), Coloring, Pick and place, and pretty much anything else that only has light side loading on the toolhead! Key Features: E3D and Jubilee TC head compatible...

Alright - I admit that I haven’t been good at all with the promises I’ve made about blogging during stablebot creation. It’s been about 2 months since my last update, and I’m sorry that I haven’t spoken enough. Things are progressing quite well in the lab. I’ve made some changes+upgrades that I didn’t expect to make, and partially due to coronavirus shipping issues, I’ve decided to swap to e3d’s toolchanger vs using the Jubilee cable driven one. I’m kinda a sucker for metal, so having the e3d-perfect machining is always a boon. Here’s a list of all the progress from...

Alright! I’ve updated these parts of my design theory: Z-Axis Switched around to a Maxwell-style mount – 10mm ball on the bed, couplers on the Rail Pieces For now, no Steel Spring Sheet. The plan is to mount the PEI directly to the bed for now, removes just one little bit of complexity. X-Axis Steel Core was a bad idea. Switching back to regular Fiberglass-reinforced GT2 belts. Frame Z+Y axis was Counterbored for 80-20 anchors. L brackets are not stiff enough for a large machine. I will be making custom corner gussets out of additional 2040 pcs that will go...

Alright, time for another update!   I’ve been able to spend a few hours modeling, and have figured out most of the items for my first stablebot build. Initial printable range is going to be a whopping 622x622x900mm! (~2’x2’ftx3’) This is including volume lost for extra-large hotends like a supervolcano, so real printable height for “standard” hotends will be closer to 1m. The model is fully parametric, so once its ready for release I’ll be able to export BOM’s for many different sizes for customizing sizes based on needs.   Few more design choices I’ve worked through: 1)      Z Axis...

I’m starting a journey to design a e3d toolchanger-compatible 3d printer made with profiled rail and 2020.  I’m going to call it the Stablebot. In short, my goals for this printer are:   1)      Accessible a.       Uses 2020 for the frame and minimal machined parts                                i.      Will be optional printed parts                                ii.      All other Metal parts will be common parts available b.       Build your own! c.       Scalable! 2)      Reliable a.       Rigid frame for rock-solid printing b.       Mechanical mesh leveling c.       Known Components                              i.      E3D V6 All-Metal Hotends                              ii.      Duet Mainboard                              iii.      CoreXY Mechanics d.       Stable Bed Platform...
