#Monolith Toolhead

We have shown a significant temperature drop in the melt zone with the sims. To counter this, I designed a 360 in the middle to achieve a more consistent viscosity across the cross section at the nozzle. Despite our current sub-optimal HF geometry, the print quality doesn’t seem to be affected noticeably compared to the SF design, which definitely has worse melting performance…

We'll make the bottom of the main body completely flat flush with the Beacon mounting surface. This will improve printability and lessen the potential warping.

It appears that with the relocated thermistor, we can reduce the Beacon Y-offset from 18mm to 15mm, which means that rear lead screw clearance is possible,...

Now that all of the M0 prototype content is out, and there still aren’t many interesting things I could share about the ongoing toolhead development, I thought I’d summarize what to expect in this next phase:…

Here’s what I’ve been working on for the non-kit extruder:…

I’ve never actually seen the full potential of my old milled heat block. Back then, we had a limitation with the filament grip. Fortunately, the first toolhead design provides a great platform for testing different hotend blocks and extruder internals…

As mentioned before, I’m going back to prioritizing the toolhead development over everything else, which entails making some improvements to the universal belt clamp design that many of us have already been using. A derivative of this will obviously go into the updated toolhead itself…

I took other thermal images to add to the collection! I added back the fiberglass silicone sleeve, and measured it with the same conditions as before (255 °C, max speed 9290)…

To compare with the previous thermal images, I captured another series of pictures of the heatblock, this time at both the minimum and maximum fan speeds achievable by my 9290. The images were again taken at ~255°C with the chamber at ambient temperature. The first set shows minimum speed, the second is at maximum speed…

I captured a series of thermal images of the heatblock to better visualize the temperature gradients…
