Thanks for the tip, I will try to adjust my z-speed. I don't see where I can adjust that though, can you point me in the right direction? I'm running Cura 14.01 on my MacBook. Thanks! Yes, I updated the firmware. At least I thought I did. Can a check the firmware version on the Ulticontroller? Where can I get the latest firmware download? Thanks again!

Hello all, got a couple issues I'm trying to get solved now. 1. Trying to clean this print up. Im getting these bumps on the outside wall where the printer starts/stops and moves to the next layer. I'm printing on an Ultimaker Original with a .65mm nozzle. I'm printing with ColorFabb PLA and I'm printing Hot 235-245 and at 75mm/s, .8 shell thickness, .5 Layer height. Retraction is stock setting at : Speed = 40, Distance 4.5. Do I need to tweak the Retraction settings since I'm using the bigger nozzle? Any tips would be appreciated! 2. I keep getting a "Heating Failed" error. Only happens when the Head is hot and I try to print back to back fast. Turning the Ultimaker Off then On solves the problem. I read on here that it's caused by the temperature not climbing over 20 degrees within 40 seconds? Any idea why this is happening? Having a fun time printing and getting to know this new machine! Hopefully I'll learn a lot a be able to give back to this community soon.

Thanks for your responses guys !Got it working, though I'm not sure how..... which bugs me. I took printhead apart and put it back together to check all everything and also so I know how to do it, Still got the error. Switched to the secondary temp sensor, still got the error. Unscrewed the wires and put them back in, still got the error. Finally I took all the loom off the the wires that run to the print head along the bowden tube and rewrapped them, didn't get the error anymore. I'm sure theres a messed up wire somewhere. I need to take apart the wire loom and better inspect everything. I'll find and fix the problem. In the meantime, I need this machine to make money for me so I'll just keep running it unless the problem resurfaces and forces me to fix it. I wish I would have bought the kit and put it together myself, that way I know how everything was put together. I may be in the market for another printer and if so, I'll probably buy the kit. Is there a place in the US where I can easily buy replacement parts for my Ultimaker?

Hello all, Just got my ultimaker last week and its been going strong since then. I ordered the fully assembled model from MakerShed. This morning I got a max temp error and I keep getting it. Checked the wires on the top of the print head and they looked like they were touching so I moved them apart....Still getting the code. The temperature reading on the ulticontroller is bouncing all over the place. http://www.youtube.com/watch?v=A1Y3m9Q0jh8 Eventually it jumps over the limit and throws the code during prints. Whats weird is if its not printing and I just control the temp, it heats up fine and stays within a few degrees of set temp. Do I just have a bad Thermocoupler sensor? Any info, advice or steps i can take to narrow this problem down would be greatly appreciated !
