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…

As promised, we're working on the remaining printed parts. One of the most striking features of the design is definitely the handles…

I'm also getting pretty close to a working printer. It needs a toolhead and all of the electronics that I have already tested. At this point, I think I'll wait for my SLM parts to arrive…

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

Coming up with a nicely integrated, removable hinge design has proven to be one of the most challenging parts (at least for me) in this development phase…

In this episode, I made good progress on the XY gantry and the stepper mounts. The bed was also installed, but I don't like how tall these silicone spacers are. Although I've already put the gantry plates in place, but the screws weren't tightened because I wanted to see the alignment with the stepper shafts first…

Thanks to all of you, I acquired a thermal camera to aid with the toolhead development…

We've already discussed resolving the issues we have with the SLM MGN12H XY joints…

Aside from the alignment and the Z-endstop, the Z-motion is almost done at this point. Before installing the 5mm thick bed holder, I realized that it would be such a QoL improvement if I made enough clearance for the MGN7H carriages to get past the plate. So, I modified the plate using a file and updated the CAD accordingly…

Before I switched to the sheet metal gantry last year, I gave up on the purple accent color in my printers, because I was unhappy with the performance of the purple BrandName ABS blend, even in a passively heated chamber…
