I snatched a beautiful HP-71B pocket computer equipped with ROMs version 1BBBB for a very reasonable price. The computer was missing two expansion port covers, but that was fine with me, as I planned to populate those ports anyways. Regardless, I decided to 3D print two replacement covers using a model developed by hpackma under the creative license. No problem, I have this down, and I swiftly loaded the model, duplicated it, and started the print of two bright yellow replacement covers. I was only one small half an hour away from feeling the good sensation of completing a calculator. I could already hear the satisfying click! Well, that was the plan.
That’s when I paid attention to the software, asking if I wanted to use the current setting versus the printer’s configuration. What the heck?! I double-checked the new spool’s package, and it struck me: although the new reel was yellow as the previous one, it was made of ABS (acrylonitrile butadiene styrene), not PLA (polylactic acid). A simple change in the profile and the extrusion temperature was boosted. After two hours of fiddling, I was yet again, just 30 minutes away from hearing the satisfying click! I think that I just re-re-re-learned an excellent lesson: RTFM!
