3DTouch / BLTouch

Post by Adriano » Fri Oct 04, 2019 5:47 am

I see there's always a chaos because almost all peoples think that the 3DTouch and the BLTouch V3 are the same .

This is ABSOLUTELY wrong. They are NOT the same . They need a different distance value (Marlin) between the probe and the nozzle's pin : it's -37 for the 3DTouch and -40 for the BLTouch V3 .

They both need to be at the right height (templates are on Thingiverse) , please avoid the silly method wich tell you to pur a 1.5 or 2mm Allen key ..use the template from Thingiverse....there's a reaso for and it's well explained on the BLTouch instructions .

The BLTouch V3 need bit of work on Marlin ( adding some stuff ) and you only can do this on Marlin 1.9.1 bugfix or Marlin 2.
Here's what to do : https://github.com/InsanityAutomation/M ... fa77682715

Please note that these mods wont' work for the 3DTouch . They are to "force" the BLTouch V3 to work as intended, forcing some status, adding some features etc.

Again : the 3DTouch and the BLTouch V3 looks the same sensor but they are NOT : this is the first thing to understand.
