Ultimaker 2 - need to run the feeder motor to run in reverse

Recommended Posts

Hi all,

       Got a new feeder on my UM2  ( https://www.youmagine.com/designs/alternative-um2-feeder ) but i need the feeder motor to run in reverse, can i just use the UM2+ firmware instead ? or is the UM2+ firmware designed to use the UM2+ white feeder. Or is there another way, like reversing the wires on the board, so stepper motor runs in reverse ? Any help greatly appreciated..

Yes you have lots of choices.  

 

1) UM2+ firmware will work as that goes the other way.  You will have to adjust steps/mm most likely.

2) You can install tinker marlin - which I love - and which lets you toggle all feeder directions and adjust steps/mm in the menu.

3) You can swap the two wires in either (but not both) twisted pair.  You just use a pin and push down on the angled piece of metal that holds the pin in and slide the pin out, then rebend that tiny piece of metal so it will start working again, swap the 2 wires and re-insert.

 

You will probably need to change the steps/mm regardless.  I don't know if the um2+ firmware supports that or not although there is an gcode to set steps/mm.  Followed by M500 to save it so it still works after power cycle.

 

So it might be easiest to do #2 above.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
