Most UM2s have a dedicated fan port, highlighted in green on this picture. The very earliest ones don't have one. I've indicated the pins used for the rear fan in blue.
Yes I had accidentally placed the orange blue wire fan into 8/16 connector. I now fixed it and changed it to where it should be (In the green box indicated in the picture attached.
But according to the Ultimaker 2+ instructions video, the yellow green wires for the rear fan are supposed to go 'FAN PWM' (Light blue box in my picture) and that's where they are placed even in an another UM2+ I own. Thus that where I hae them right now unlike the pins marked in blue box in your picture.
Now when I changed the port and turned on the printer, the buildplate rises and hits the extruder so I manually shut the printer down.
I also upgraded the firmware to 2.3.
I would do a factory reset but am not able to get past the calibration point due to the build-plate bumping into the extruder in the first step.
Thanks for your input. You were correct to point out that I placed the connector in the wrong slot. What should I do now?

A bit of a longshot, but did you accidentally connect the fan wire to the microstepping header on the board instead of the white connector?

Since I just did the up gradation, am stuck on the calibration process. The printer wont let me move ahead to raise and lower the build platform. But, I checked the Z Limit Switch. Its is functioning properly.
Checked all wires. They see intact.
Thanks

Hi,
I upgraded Ultimaker 2 to Ultimakr 2+ with their extrusion upgrade kit. Watched the video of instructions and did it exactly as per the instructions (Have done a similar thing to an other UM2 printer and was installed successfully).
Please watch the attached link for the video
After up-gradation kit was installed the firmware was upgraded to version 2.3. Started the calibration process after turning on the printer. After the calibration step is about to complete. The build platform moves not all the way down (Shown in video) and gives an
ERROR - STOPPED
Z Switch Broken
Thought it was an firmware issue. So changed the firmware from Cura 2.3 to 15.04.6. But the problem still exists.
Checked the Ultimaker website for troubleshoot 'ER05' and according to it I checked the main board and all connectors to ensure all connections were not loose.
Please help me recognize what went wrong during installation.
Best,
Small

Hello Neotko,
Please see attached image. Its the polou info for the company that makes steps motors locally: BH42 SH 47-1704 AF . The only major difference I see if I am not wrong is that the one Ultimaker 2 uses SY42STH38-1684A has Drive Set - Voltage 24 VAC Constant Current: 1.68 A Half Step and the one available to me Drive Set - Voltage 24 VAC Constant Current: 1.7 A Full Step. Does that make a difference?
Thanks for all your help.

I found a local supplier with the following specifications:
NEMA 17 stepper motor with a 1.8º step angle; Holding torque 0.44 Nm/4.4 Kg-cm. Current 1.7 A
Does anyone know if it should work?
Thanks!
-
Yes I checked, its the stepper motor. I peeled off the sticker from the motor, here are the numbers I foind on the sticker:
SY42STH38-1684A
060038101
The dimension on the Y axis is motor are: 39 X 40 mm.
Thanks!

Hi,
My Ultimaker 2's stepper motor (Y Axis) doesn't work anymore and I urgently need to install a new one. Ordering one form ultimaker will take a long time. Anyone aware of the configuration of the kind of stepper motor they use in Ultimaker 2. Is it NEMA 16 0.9 or 1.8?
Thanks in advance.

Hello all,
Thank you all so much for the support. The Y motor was the problem. I dissembled it from the unit. Upon inspection, the turns were a bit rigid. Opened the motor, then took the rotor out. I manually turned it a couple of times till it was smooth. Put it back and now its working fine.
Really appreciate all your help! 8)

We tried to narrow down the problem to X and Y axis. For that we made the printer run X axis and Y axis in 2 separate prints. Here are the results.
Y Axis Print:
X Axis Print:
Seems like some problem with the Y axis (Motor). Any suggestions?

I think the left to right limit switch is ok, but I wonder if the front to back microswitch is defective it may be worth checking that the cable to it has not been pinched behind one of the steppers, or maybe you could test the switch's function with a multi meter
Thanks for getting back. I will try opening the micro switch as you mentioned and check it with a multi-meter.

Have you tried re-installing firmware and doing a factory reset of the machine? It almost sounds like it's trying to rotate the steppers too fast. It made this noise before you lowered current as well, right?
And if you move the head around by hand with power off, does it feel smooth? Does it require excessive force to move?
Thank you for getting back. We did update the firmware when the machine started to act out. But did not factory reset. But am going to try and do both again.
Yes, it still made the noise when we lowered the current.
The print head moves smoothly with the power off. Will do the necessary like you asked and post soon. Thanks again.

Thanks for responding @IRobertI. sorry about the video. Posting better video's below.
I did check all the pulley's. Yes, that included those on the motor shaft as well. I tightened all of them. They seem to work fine.
The belt aren't skipping teeth. Checked on that. Nothing is scraping against the walls of the machine. Oiled all the rods. The noise seems to be coming from the print head.
When I try to home the print head, this it what it does:
Then its reads X or Y limit switch broken on the screen.
I checked to see if the X limit switch was working: Its works fine. As shown in the video below:
I checked to see if the Y limit switch was working: Its works fine. As shown in the video below:
Here is an overview of the machine as it is right now. I have focused on all the parts. I can't seem to figure out what might be broken.
Thanks!

If the problem is a micro switch it looks like the one at the back (x axis) where you can see two screws back left, you should be able to hear it working or not by moving the head to the home position.
Thanks for your response. I checked the limit switch in the back on the X axis. Seems to work fine. I hear a click. Checked the Y axis limit switch as well. It works fine too.

Hello,
I have looked and looked to see if anyone else encountered the problem I am facing with my UM2. Unfortunately I havent seen any posts that match my problem so please help me get this printer running.
Here is a video to illustrate the issue.
We checked the X limit switch, the Y limit switch manually. They work perfectly fine. Printer head when manually moved works fine without excess friction. The pulleys are tight (Compared them to my other UM2). We updated the firmware when we first encountered the problem . The current firmware updated is 15.04.2
According to 3dverkstan guide on troubleshooting, we lowered the X & Y 1300mA to 1150mA and then to 1100mA The problem still persists.
Kindly send in your input on how do I fix the problem.
-
Yes, checked the pulleys. They seem tight. Compared them to the other UM2 I have. Seem to be the same on how tight they are.Have you checked to make sure the pulleys are tight?

Checked the cables, none are touching the gears.

Can you move the head around by hand?
You can unclip the head assembly from the black guides that are connected to the belts.
One removed you can individually check to see which one might be stuck.
Yes the head is easily movable. When tried to move it to home base. Its easily moves back from any position.
-
Check the end switches
Check that the two middle shafts (the ones that cross the head) ain't touching the sides or the front of the um2 structure.
By end switches - Do you mean the limit switches? If yes, I checked them. They seem to work fine. The two middle shafts also do not touch structure of the UM2.

Hi,
My Ultimaker 2 has been printing fine for a couple of months. Today the print head started making a really loud noise and was stuck on the 5-6 layer while it was printing an object on X and Y Axis. I shut the printer and retried the print. It did the same thing again.
I updated the firmware of the machine immediately and retried to print. Also the Cura is up to date. Same problem persists.
We tightened the pulley, greased the rods. But it was no help
Please see the attached video to understand better.
Any help would be nice.
Thanks!

I received my second Ultimaker 2 today. I was inspecting if anything was broken in transit and that's when I noticed a crack running from top to bottom of the black body of the printer head. Please see pictures attached below.
Is this supposed to be there or did it come broken?
i checked my old Ultimaker 2 and noticed it has the crack as well. But the crack formation seems different than the new one. I believe it could have cracked from the use.
Should by new Ultimaker 2 have it as well or is it broken?
Thanks for help

I tried the atomic method. During the cold pull, I noticed that there is a small blob right below the triangle at the end.
Please see pictures attached. I do not recall seeing such in the past.
Could that be due to the deformed coupler?
@gr5, I have been experiencing this issue even in a fresh filament reel. I haven't removed the coupler to see if its deformed yet. But I felt there was definitely friction while moving the filament up-down in the coupler.

I have been printing an order on my UM2 for the past few weeks. (Purchased in January 2015)
I started printing it with PLA (ColorFabb) at 210 C; Layer Height 0.2 mm; Speed 60 mm/sec.
The more I printed the same file, I started experiencing issues of feeder skipping and under extrusion especially while printing the brim.
Thus, I raised the temperature to 220 C, then to 225 C and now 240 C. If I lower the temperature any less than 240 C, the extruder starts under-extruding and the feeder starts skipping a lot. Now the problem occurs while printing the brim as well as the actual object. (Layer Height 0.2 MM; Speed 60 mm/sec)
Using 14.12 Cura Firmware since newer versions created issues while printing.
My print quality has greatly deteriorated. Some layers are missing.
Can anyone explain how to fix this issue?

Upgraded UM2 to UM2+; Error in Z switch after upgradation
in UltiMaker 3D printers

So here is what solved the issue. We changed the firmware to UM 2. Then tested the machine. It worked fine. So then we changed the firmware to UM2+.
The problem is resolved. Thanks to all who have answered.
