I didn't know you were an opensource arsonist. :)

working with eagle a couple years ago i was so shocked by the unprofessional use of 0.5 amp thermals in RAMPS 1.4 i felt compelled to document it:
https://reprap.org/wiki/RAMPS_1.4#WARNING_-_THERMAL-isolation-related_DESIGN...
there is not enough space and the 0.5 amp thermals are completely inadequate anyway, leading to in some cases only something like 2.5 A maximum safe current capacity when the total load can be as high as 6.0A. that can result in something like a 25 to 30C temperature rise above ambient for the rest of the PCB.
once one of the thermal tracks burns out you get runaway.
yes i met someone who had imported RAMPS 1.4 into Canada, and sold them. yes, one burned someone's apartment down. yes the FCC fined the company and prohibited them from selling electronics.
Do you have some KiCAD files of the incendiaries you used? :)
very funny :)
