Original A4988 drivers were overheating on small parallel operations.
So I made a bigger box, with same internal components, and 4 40mm fans directly on the drivers, one 60mm filtered fan for input and 2 60mm fans for extraction
After one hour of intensive 5mm parallels in the air, on every axis, temp was stable at 22°C, no lost steps
I feel invincible right now 😂😂😂
