Recap of your meeting with Port City Makerspace

[Fathom]

Meeting Purpose Review lab equipment status, plan projects, and manage budget. Key Takeaways - Laser Cutter: The autofocus probe remains disabled to prevent crashes. A long-focal-length lens is a potential solution, as it would position the nozzle further from the material, reducing the risk of collisions. - 3D Printers: A hardened nozzle and extruder gear will be installed on one printer to enable use of abrasive, carbon-reinforced filament. This will serve as a test before considering a full lab upgrade. - Budget & Projects: The lab has ~$390 to fund projects. The top priority is building a second workbench using existing materials, followed by cosmetic upgrades to the Shapeoko CNC table. - Community Engagement: The lab will connect with the robotics team to offer its surplus components, aiming to free up space and provide valuable resources. Topics Laser Cutter Maintenance & Autofocus - Problem: The autofocus probe is the primary cause of laser cutter crashes. - Solution: The probe is disabled in firmware and physically disconnected. This has improved stability, with no significant user complaints in ~2 months. - Future Options: - Long-Focal-Length Lens: This would position the nozzle further from the material, reducing crash risk. - Downside: Requires an external air assist compressor, as the built-in system would be ineffective at the increased distance. - External Autofocus Module: A separate, user-placed module, similar to the Shapeoko's. - Risk: Users might forget to place the module, causing crashes if the firmware is not disabled. - Maintenance: - A fan needs to be installed in the electronics compartment cover to prevent overheating. - Training on optics cleaning is needed, as the last volunteer (Rye) stopped engaging. 3D Printer Nozzle Wear & Upgrades - Problem: Abrasive filaments (e.g., carbon-reinforced) cause rapid wear on standard brass nozzles. - Immediate Action: Neil will purchase a hardened nozzle and extruder gear for a specific project. - Plan: Install the hardened parts on one printer as a test. - Rationale: A hardened setup is superior for all filaments and would reduce downtime from worn nozzles. - Cost: ~$50 for the full hardened setup. - Long-Term Solution: Upgrade to an H2C hotend. - Benefit: Wireless, induction-based heating eliminates fragile wires and connectors, making nozzle swaps simple and reliable. - Spare Parts: The lab has two spare extruders but lacks spare heat cartridges and thermistors, which are critical for repairs. Lab Projects & Budget - Budget: ~$390 available for projects. - Project 1: Second Workbench - Priority: High. - Materials: Use existing plywood, pegboard, and oak banding. - Countertop: Use plywood with oak banding instead of buying a new $129 countertop, to save funds and match existing aesthetics. - Project 2: Shapeoko CNC Table Upgrades - Priority: Medium. - Hardwood Banding: Add a decorative and protective hardwood band around the table's perimeter. - Protective Surface: Install a hardboard sheet under the CNC to create a durable, cleanable surface for spills. Reservation Clock & Soldering Station - Reservation Clock: - Status: Development is ongoing. - Technical Fix: Fixed a bug in an open-source HTTP library that prevented the clock from fetching Google authorization tokens. - Impact: The fix enables correct handling of "chunked transfers," which are used when the server doesn't know the full response size in advance. - Soldering Station: - Issue: The Hakko soldering iron's calibration is off, causing poor performance. - Cause: The confusing two-button UI makes accidental calibration changes easy. - Action: Recalibrate the iron using a thermistor. - Future Upgrade: Design and plasma-cut metal stands for the Pinecil soldering irons. - Feature: Stands can include a magnet to trigger a Hall Effect sensor in the iron, enabling automatic, instant standby mode when docked. Next Steps - Lincoln: - Arrange for fan installation in the laser cutter electronics cover. - Test the spare 0.4mm 3D printer nozzle. - Coordinate with Neil on installing the hardened nozzle/gear. - Build the second workbench using existing materials. - Design and plasma-cut Pinecil soldering iron stands. - Attend a robotics team meeting to offer lab components. - Roman: - Recalibrate the Hakko soldering iron. - Check the whiteboard for other project ideas.
