Marlin UMO+ Dual Extruders

[neotko 1,417]

Hi,

I have modified the marlin configuration.h

 

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

and also

 

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

If your UMO+ is standard (no other changes than the dual head), there is a dual firmware distributed with Cura.

Alternatively you can generate a firmware https://bultimaker.bulles.eu/.

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?

[amedee 349]

Cura does not propose you, but the firmware is there, look in the Cura directory.

Other than that, the only changes are indeed the number of extruders and the temp sensor, so you should be could.

 

[neotko 1,417]

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?

[amedee 349]

No, you should have them in the menu...

Can you please try https://bultimaker.bulles.eu/ to see if you get the same problem?

 

[neotko 1,417]

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 ). Now I see Nozzle2 on the temperature adjustments. Thanks a lot Amedee!

 

[amedee 349]

You can change the LED power from the Control menu...

What is this timeout thing?

[neotko 1,417]

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

 

[amedee 349]

It is the default firmware, with a couple of additional tweaks, including LED brightness support

I'll add the timeout in the build parameters...

 

[neotko 1,417]

That's awesome! It's on

ultralcd.h

#define LCD_TIMEOUT_TO_STATUS 15000

 

Thanks a lot for your help, and speed-of-light-replys!

 

[amedee 349]

I have added the timeout feature in my builder.

It should work, but I have not tested it ;-)

 

[neotko 1,417]

Works perfectly! Thank you. Btw the extruder2 can't be controlled from the menus right? Just wondering. Thank you again

[amedee 349]

Right, only the 'main' extruder.

I had a quick look at the code and it is not something that can be added in 5 minutes due to the way extruders are handled...

Hey everyone,

I want to give my UMO+ an second extruder, need an special firmware to do this.
There is a very nice and handy site for this, https://bultimaker.bulles.eu/

When i try to build a firmware, i get a fault warning! 
Cannot create build directory" Is there something i can do? Thanks in advance.

Looks like that site is no longer properly configured. There is nothing you can do about that, short of notifying the site owner.

Cura comes with a precompiled dual extrusion firmware for the Ultimaker Original. Did you try if that works for you?

[Servpeet 0]

Thanks ahoeben, the original has an other motherboard. Wil not work i assume.

[ahoeben 1,965]

There's also a precompiled dual version for the UMO+ (sorry, I missed the +): MarlinUltimaker-UMOP-250000-dual.hex

[Servpeet 0]

Found it, Thanks!

 

https://github.com/Ultimaker/cura-binary-data/tree/master/cura/resources/firmware

 

But, i want to compile my own one with: 

 

Software homing top, filament detection , Fan%, quickstart fans and autodriven fans by second extruder.

 

But this download is an nice step in the wanted direction.

[ahoeben 1,965]

You did not have to go find them, they are included with Cura.

 

If you want to compile it yourself, your best start-off point is https://github.com/Ultimaker/Marlin/tree/Marlin_UM_Original_Plus
