That is definitely an area of the product that could use improvement. When we first introduced the UTM PCB with Genesis v1.4, we did look at using other connectors, including ones that screwed together. At the time though we didn’t find anything we liked that also fit the tight space requirements - specifically the area between the UTM bosses that the three M5 screws mount to. While we could have changed the entire form factor of the UTM, that was a tradeoff we made to keep UTM/tool compatibility with prior versions.
Fast forward several years and product versions and I’d say that the whole UTM and Tool form factor is due for a breaking change that improves all of the key areas that matter: mounting/dismounting reliability, tool verification/power/comms, ease and robustness of mechanical assembly, supporting a variety of custom tool use cases while not making tradeoffs with out of the box functionality. You can expect this to come in Genesis v2.0, along with other major overhauls of FarmBot’s electrical architecture! And we’ll also make sure to offer upgrade paths from v1.x to v2.0.
