I'm building a rockstock mini pro.

I’m building a rockstock mini pro. hardware was easy as pie but Ive never bothered with auto leveling on my printers. Can someone point me to a tutorial. I would go with proximity sensor but local suppliers are on back order, will upgrade to it later anyway but for now something with a micro switch will do.

When it comes to auto leveling on Delta’s there are many solutions but allot of it comes down to two major parts. Firmware and Print Surface. What firmware are u planning on using, Marlin, Smoothieware? Also are you printing on Glass, PEI or a metal surface. I for one when it comes to Delta’s prefer to use FSR sensors for Auto Leveling as they give some of the most accurate reads and you can use any print surface you want. Check out Ultibots.com for their FSR kit and they also ship worldwide.

Thanks. Will be using marlin on ramps. Glass bed.

If you are/were intending to use inductive proximity sensors, my experience with them is that they are ok for use a Z axis bed height sensors if you calibrate the Z height and only use the sensor in the same spot each time under the same bed heating conditions. If you intend to use inductive sensor with heated bed, say glass on thin 1/8" aluminum plate with say heated mat under the plate, you may find like I did that the bed heating element affects the inductive sensor readings making it practically useless for doing auto bed levelling across the bed. The inductive sensors are intended to work best when measuring off thick iron/steel pieces rather than thin aluminum with heated mats. FSR with smoothie for example works so much better. Another option is to use normal limit switch trigger on the hot end effector with an extendable touch off rod setup. A further option is to use IR distance modules… Look up on Google David Crocker IR module. Have not tried IR on delta yet, but works great on Cartesian driven by smoothie with glass bed and black painted aluminum plate and heated mat. Have fun.
