As such I arrived at my first design iteration: I started off by importing dimensionally accurate models of both the Ender 3 v2 print head assembly/x-carriage and the BL-Touch:īy doing so, I would be able to project the precise positions of mounting holes onto the sketches for component of my attachment, rather than measuring by hand with some amount of inaccuracies.Īnother requirement I came to realise was that it would be useful would be the ability to remove the plotter attachment when it is not in use. I’ve been getting more and more familiar with Fusion 360 since buying the printer, so was confident to get straight to prototyping a design. Not good!įrom here, the only logical solution was to design my own, which accommodated for my specific requirements. Due to the way it mounted it now meant that the hot-end carriage could no longer hit the x-axis limit switch. I printed it and mounted it to the printer… job done… right? Unfortunately not. It supported mounting of the BL-Touch probe without needing to remove the hotend assembly. Ender 3 v2 Pen Plotter addon ), however most of these either required you to fully remove the hotend assembly or did not accomodate mounting a BL-Touch levelling probe.įortunately I managed to find this model which both accommodated both of my requirements. Surely someone had done this before! I managed to find a handful of models (e.g. So as with most projects I undertake, rather than re-designing from scratch, I opted to start searching for existing projects. However, in almost every case these are cost prohibitive for hobby embroidery projects and also happen to incur a long turn around time from order to delivery. Unsurprisingly, there are services available which can do this, albeit using machine washable dye rather than heat reactive dye in most cases. In my case, I was tasked with automating the process of drawing an embroidery pattern onto fabric using a heat/friction erasable pen for my partner, Kate. It turns out having a CoreXY 3D printer allows you to do more than just 3D printing if you’re willing to get creative. It was a logical purchase, to compliment my home automation hobby, allowing me to design and print custom enclosures for miscellaneous ESPHome and Zigbee nodes. Here I’m installing the pen gripper which is simply attached to the servo motor through the servo horn.Last year I purchased myself an Ender 3 V2 3D Printer. There few final touches that needs to be done in order to complete this pen plotter. For powering we need 12v power supply with a minimum current rate of 2 amps. We have three micro limit switches for homing the machine and a small servo motor for the gripper mechanism. So, we are using an Arduino UNO board in combination with a CNC Shield and three A4988 stepper drivers.

You can get the components needed for this project from the links below: All of the bolts for assembling this machine are actually M3 with various lengths except for few M5 bolts needed for GT2 pulleys.
I started by securing the base plate and the bracket for the linear rail together with the help of some M3 bolts.
