Didn't even know there was a forum for Cube3 modders :)
I posted the picture of the E3D hotend on Facebook hoping to produce some attention for the Cube3 printer. The proprietary nature of the device casts it in a bad light and I felt like offering a full conversion to an open source machine would make it at least a little more popular. Can't really beat what you get for ~$100 these days.
I'll be releasing the E3D hotend files, along with numerous other files, very soon. The last work I have to do (other than a bit more testing) is relating to endstop placement. I have the concepts worked out, just need to turn them into reality now :)
I can't wait to see this in action!! It would be really cool to be able to use off the shelf parts to extend the life of this printer. I actually get really good prints with it now and I worry what I will do when it dies lol. Parts are going to be scarce for it soon I'd imagine.

now just look at what you've done. Going to make me convert mine! This look fabulous. Cant wait to see what the final results bring. What type of tweaking would need to be done to the computer part if any?
Technically it can be used with the default but you'd need to setup a proper resistor to provide the computer the feedback it's looking for. I'm going to be using a RAMPS board with itQuote:

Initial goal was to keep the electronics, but finally I gave up on this idea as the board of the Cube 3 is plain stupid. So, for now the goal is to make it work with 32bit MKS SBASE 1.3 (running Smoothieware) plus MKS TFT24. Apparently TFT 24 has exactly the same screen that Cube 3 has, which makes things much easier. It must have the heated bed too. The parts are already ordered and I'm hoping to have them by the end of the next week.
Here are my designs:

Some initial prints and assembly:

Playing around with MKS SBASE board placement :) That is probably the best way to place it, but will require grinding off some parts of the metal frame.

Currently I'm fighting my OCD regarding the placement of the optical endstops :D Probably placing them on double-sided scotch tape is not a great idea :D Comments and suggestions are welcome!
Ditch the optical endstops and use TCM2130 instead. Sensorless endstops via stepper motor feedback
Interesting idea! But the board already has DRV8825 drivers installed, in this case I'll have to use the external drivers. My concern is already limited space plus this approach may not be very good for the belt teeth health. That's the way Cube 3 original board was dealing with the endstops, but it was not doing it very well, the sound of skipping belt teeth drove me crazy :DQuote:
