Marlin UMO+ Dual Extruders

Recommended Posts


I have modified the marlin configuration.h


// This defines the number of extruders
#define EXTRUDERS 2 <-- was on 1, so I changed it to 2...

and also


#define TEMP_SENSOR_0 20
#ifndef TEMP_SENSOR_1
#define TEMP_SENSOR_1 20 <- was on 0 but I have a pt100)
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 20

But after uploading it I can't seem to be able to tune or check the temperature or move the second extruder. Where else I must edit to activate it?

(I have a 280W power supply connected to my UMO+ since the first day so I'll have enough power to use the dual extruder and bed).

The line that confuses me it's that 'ifndef tem_sensor 1'. If I remove the ifndef it fails to compile so that isn't the issue or is it?

Any kind soul can point me on the right direction? The info I find on google it's mostly from 2013 and the marlin it's different.

I have do that modifications. And Cura don't let me choose 2 extruders while adding a new machine but for umo not plus it gives the option. So I'm compiling and uploading the marlin with the changes above (using lastest firmware for umo+) but It don't works. What I'm I missing?

That's the think. I have compiled the umo+ firmwareon arduino (not my first time since I added led power control). But after doingthe changes I list nothing changes on the tune menu and I can't see or change the second extruder temps. It's that normal? Maybe dual only worka by gcodes?

That works, now I need to find the way to include the ledpower modifications on that and change the timeout so it's more than 15000 millisecs (too small for my :D). Now I see Nozzle2 on the temperature adjustments. Thanks a lot Amedee!

Weird, a month ago the default firmware didn't had the led control, superb.

The timeout, it's the delay it takes for the screen control to go back, I like to have more time while touching stuff so I don't have to go all the way into the click click. Anyway, it works so I'm very happy :D

    • "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.
