Comment on Modernizing an Ender 3

  CR touch and BL touch are the same. It’s just creality’s name for it.

  Inductive probes are probably the cheapest option. I paid around $5 for mine and it works great.

    They accomplish the same thing, but the probe itself is very different.

    Taken from a helpful reddit post: *The BLtouch is based on an hall-effect sensor, while the CRtouch has an optical switch. The BLtouch has a plastic and pointy pin, while the CR has a bulkier metal pin.

    The CRtouch is slightly more precise than the BLtouch with a lower deviation delta. They both are more sensitive than the minimum stepping distance of 0.025mm that is found most frequently.

    The BLtouch is at its fourth (3+1) iteration, while the CRtouch has been released relatively recently. There’s a lot of information on the BLtouch available on Antclab’s website, while there’s pretty much none for the CR.

    I would go for the BL for two reasons: the smaller footprint of the probe behaves better on textured surfaces, and beacuse hall-effect sensors aren’t subject to drifting when aging (unlike the optical switch in the CR, that technically “wears out” and starts introducing an offset to the measurements).*

      Thanks - I didn’t realize that crtouch is optical.

  Creality cloned the bl-touched and called it crtouch
