  1. Easy to Implement!

    Posted by Unknown on 9th Jan 2017

    This kit worked great out of the box - just had to print cradles for the sensors. Highly recommended.

  2. Easy Setup

    Posted by Steve on 25th Nov 2016

    Looked around a bit for the individual parts. Found the whole set here, and didn't look back. My printer has never had such a nice calibrated bed!

    Works perfectly. No more manual leveling. This kit is worth every penny.

  5. Really good kit works great

    Posted by Simon (Demon3d - KIngswood 3dhubs) on 29th Aug 2015

    I installed this on my Kossel Mini with 200mm aluminium heated bed. I used these mounts for it which seem to work well. http://www.thingiverse.com/thing:696613 and used the Master branch of Rich Cattells Marlin https://github.com/RichCattell/Marlin/tree/master . First time auto calibration worked perfectly. Autolevelling works also.

  6. crocky FSR Kit Review

    Very nicely presented kit with all the parts needed to get up and running really quickly. Well done!!!

  7. Excellent kit - Link for 1515 bed mounts

    Posted by Ike on 27th Jul 2015

    This kit is fantastic. Had all of the parts I needed ready to plug and play. What more could you want? I definitely recommend using the cork spacers/insulators that are provided. They are a greater buffer between the FSRs and a heated bed. The slim stickers I initially used still heated up and messed with the FSR readings.

    If you need a bed mount for the FSRs that work with 1515 extrusion and handle the added bed height with the cork insulators I create a model that can be found here: http://www.thingiverse.com/thing:944706

  8. Great kit for Delta Printers

    Posted by Darren Pruitt on 15th Jun 2015

    All the components in one kit. Easy to setup this way and don't have to worry about having to make connectors.

  10. Nice bundle!

    Posted by Arthur on 20th Apr 2015

    I was involved in the long online thread where JohnSL first announced his FSR endstop controller board, and actually pushed the drive to get his code running on the Adafruit Trinket because his boards were not in production yet. After having sourced the Trinket, FSRs, and wiring myself the first time, I gladly grabbed JohnSL's finished board and the awesome kit that Ultibots put together. I am not disappointed! When I ran this setup through three Z-height probes on my new printer build, all three results were identical out to four decimal places! Can't get much better than that.....
