Servo Driver compatible with RAMPS (STEP/DIR) Hi all, I want to drive a servo with encoder and gear (still looking up the specs) using my Ultimaker Ramps board. Therefore I am looking into a servo driver that accepts the STEP/DIR signals as input so I can keep simple drop in replacement with my electronics and firmware. I was looking at both the Geckodrive 320x or the UHU Servo drive: [www.geckodrive.com] This one seems ready out of the box (if my servo is compatible) and the price is decent. [www.uhu-servo.de] DIY approach, source chip, board, parts etc. Maybe in the end as expensive as the Geckodrive? Has anyone any recent experience with using a servo in such a way that it is as much 'drop in' as possible using one of these drivers or similar? ps. Please no 'Why not use stepper instead of servo", I know all the differences etc. I REALLY need to drive THIS servo :) https://reprap.org/forum/read.php?160,215539,215539#msg-215539 Wed, 07 Oct 2026 02:25:56 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?160,215539,450393#msg-450393 Re: Servo Driver compatible with RAMPS (STEP/DIR) https://reprap.org/forum/read.php?160,215539,450393#msg-450393

Excellent, thanks for pointing out. Looks very useful!]]> unfold Stepper Motors, Servo Motors, DC Motors Sat, 03 Jan 2015 09:59:57 -0500 https://reprap.org/forum/read.php?160,215539,449666#msg-449666 Re: Servo Driver compatible with RAMPS (STEP/DIR) https://reprap.org/forum/read.php?160,215539,449666#msg-449666 www.youmagine.com]]]> misan Stepper Motors, Servo Motors, DC Motors Thu, 01 Jan 2015 07:17:50 -0500 https://reprap.org/forum/read.php?160,215539,217047#msg-217047 Re: Servo Driver compatible with RAMPS (STEP/DIR) https://reprap.org/forum/read.php?160,215539,217047#msg-217047
Thanks for the response, exactly what I needed. I also feared that sourcing all the UHU gear with all the shipping would end being similar cost wise (but much more time wise).]]> unfold Stepper Motors, Servo Motors, DC Motors Mon, 10 Jun 2013 07:37:59 -0400 https://reprap.org/forum/read.php?160,215539,216149#msg-216149 Re: Servo Driver compatible with RAMPS (STEP/DIR) https://reprap.org/forum/read.php?160,215539,216149#msg-216149 Jim Fong Stepper Motors, Servo Motors, DC Motors Fri, 07 Jun 2013 02:41:32 -0400 https://reprap.org/forum/read.php?160,215539,215539#msg-215539 Servo Driver compatible with RAMPS (STEP/DIR) https://reprap.org/forum/read.php?160,215539,215539#msg-215539
