Yeah it's still alive. Now it's controlling better the temperature. I really don't get it. Now when i use 195 degrees, it stays in 197 still.

Hi, i'm planning to install some color LEDs, does anyone know the type of LEDs UM2+ extended uses? Watt? Volt? Thanks

Nice, can't wait to print all the parts to try. I'm still waiting for the second extruder kit. What materials can it use? 1.75mm or 2.85mm?

Test run success (mostly, it's not the best quality, but it's a start). It's way better 2.85mm haha, but 1.75mm is so cheap in comparison. Settings Tinkergnome Tinker V17.02.1 PLA makerparts 1.75mm Temperature: 200-210 (still tinkering) Flow: 100% Step/mm: 94.6

I will try those numbers, thanks. The heater is a 12v 40w. Anyway how can i make the pid auto to work? EDIT: still have the temperature issue, i use the 40W PID 6.5, 1.5, 60 as gr5 recommended. I put the temperature in 185 target so the real temperature is around 200-210 degrees Celsius. That way i can still print, but with 10 degrees of oscillation. Not ideal but it works. I will try this and see if it works (finger crossed) https://www.lulzbot.com/fine-tune-your-marlin-pid-settings EDIT2: Just tried the Pronterface without any success. I get "temperature too high" like in the firmware. What i don't understand is why the original firmware doesn't have the temperature problem.

Hey great response from everyone! I can see why everyone likes ultimaker (me included), it's because you got a huge community helping you with every problem you have. Tinkergnome firmware: still having the same temperature problem with the stable version and the new version. I will try again later with the PID. How do you set PIO 0 in the firmware? Do i have to send a gcode command from usb? Feeder step: I did a test with 100mm of material and calibrated the step/mm like the video. It' great that you can do it with tinkergnome firmaware from Move Material. Now i can use 100% flow and still getting better results. I have some gaps (underextruding) so i think i have to play a little more with the feeder steps calibrating more. It's a shame i dont have a stable temperature. That's the only thing i have trouble now.

New results, just tested the Tinker V17.02.1 PRERELEASE The results are the same, i set the temperature to 190 and i get a 210, when it lowers to below 200, i rises again to 210. Auto PID doesn't work. Printing has still the same issues. What i did: factory reset, bed leveling, change feeder step, change temp, change retraction, change flow.

Is there any tutorial or guide calibrating the steps? EDIT: Hi, i just tested the tinkergnome firmware (V16.08.2 stable version). Great firmware with a lot of settings, too shame i have this issues: I don't know why, the heater began to behave erratically: i set the temperature to 190° and it offsets to 220°. After that it began to descend to 208° and then it rises to 220°. I tried the auto PID in temperature control, it heats so fast that i get an error of temperature too high. I tried lowering the PID manually and i still have the same problem. I didn't have any temperature issue with UM2+extended original firmware. I lowered the steps of the feeder to 200 (from 369 something like that). I still have the same problem: every time the extruder passes above the layer, you get a small line, like a cut to the print. I set a factory reset, recalibrate the hot bed level again, and printed 3 times again. Lowering the flow to 60% get's a better result but i still have the same problem (the cut in the print). I don't know what else to tried. It's not like it's not printing, it's just that i tried all the possible solutions and still without an answer.

Thanks i will try today. Sorry to ask, what do you mean with a 100mm extrusion? Is the size of the 3d print or the lengh of filament used?

I'm kind of new on this, how do you calibrate steps for the feeder? I'm using the original firmware for UM2+ extended and there is no such thing in the settings. 100% flow you get a deformed print.

I will indeed wait his prototype. It seems the only working one. Thanks for the reply

Hi, i'm having troubles using a custom 1.75mm extruder. I bought a kit (see pics below) that has everything needed for 1.75mm. Even a 2mm bowden tube. Settings: i found out the best setting to print my filaments (makerparts 1.75mm) is this 46% Flow 200° temp 7.5mm retraction The results are this At first you get a clean first layer, but every time the extruder passes above the layer, you get a small line (see pic), after 3 or 4 layers of printing, the results are worse like the last image and you have to abort the process because the nozzle is "hitting" the 3d printing making a weird sound. I tried: lowering the temp or using more temp changing flow setting only get matter worse setting more than 8mm of retraction doesn't change anything. Less than 7mm you get the last image in the first layer The feeder that i am using is a Chinese one (it works, i don't think is the best). Anyone has the same problem?

So let me see if i understand correctly after reading the forums: 1) We still don't have a extruder kit that works right. Everything is still in "working progress" after two years of development (since the ultimaker dev team decided to abandon the UM2/+ and completely redesign the extruder for UM3, a lot of people abandoned the UM2+ dual extruder). 2) Active members like foehnsturm and ultiarjan are the only one with a prototype with dual head instead of dual hot-end. It works as far as i can tell from the demos, but it's still a prototype meaning, no final product, no date of arrival, or details for how to build the dual head yourself (which i think is gonna be complicated.) 3) There are a lot of issues with power consumption, hot end temperature, hot bed leveling and finally the firmware. It seems people use the tinkergnome custom firmware for dual extruding but the stable version is only for UM2. not for UM2+ extended dual. (see link). The latest firmware is a prerelease for testing purposes, the stable release of the custom firmware doesn't have the UM2+ extended dual. 4) All those dual extruders kit like ultimaker2x or E3D Chimera seems a little shady. I don't know if they work or not. Some people seems to make it work. So for the moment, as far as i can see, only UM3 has a great dual extruder, the rest of us with UM2+ have to deal with the fact that we may never upgrade to dual extruder.

Hi what do mean with not two fixed nozzles? What would yoy recommend? I'm planning to put the second extruder in my UM2+ extended with a kit. I don't want to buy it if it doesn't work correctly. Thanks.

After several days of trials and errors, i have a perfect print. I change to another brand of filament (3.0mm i measured​ it) and the result is astonishing. 100%flow, 200degrees, 0.4.. The problem that i have now is that sometimes the noozle gets clogged and you have to use the atomic method. I think is because the flow is too high right?

Hi, just got the Ultimaker 2+ extended and start tinkering around. I download this nozzle-mag and i tried to print the mount (see last picture from the author). I set it up to 0.08mm layer height and 35mm/s of speed as the author suggested. The result is this picture. I don't know where to begin to fix. I'm using 3.0mm PLA with 195°c/65°c and 67% flow rate. I got this setting from my PLA supplier. Using 0.4mm nozzle. Do i have to use a small nozzle? I have these nozzles: 0.25 0.8 0.4 0.6 Any help would be greatly appreciated.
