IR sensor vs Smart Effector
I'm planning to try out the TMC StallGuard functionality for my big delta and bought a smart effector for the probe(do home and probe each print since they're long prints anyway) But I was curious if the IR sensor is worth really installing over the Smart Effector built in? I bought an IR sensor before I got the Smart Effector but planned to use it to upgrade another old printer instead so was kinda curious about how well they compare.
Found this which makes it seem like the effector is more accurate but thought I was reading through some documentation that made the IR seem like an upgrade.
The differential IR sensor works well on most opaque bed surfaces, but when it is used with a transparent bed surface such as glass or PEI then the trigger height may not be consistent over the bed. Also it is sensitive to varying effector tilt, which is a common problem on deltas, because it is offset from the nozzle. So the Smart Effector is a better solution.
I invented both, so I don't mind which you buy!
Good deal, I'll put the IR sensor on the Cartesian I'm upgrading then that has a solid bed, works out well.
