[How to connect the heatsink fan for E3D v6 hotend on Original+?]

Ah, fantastic, I bought the 24v version but I assumed that was referring to the heater cartridge and picked up somewhere that the fan was 12v, I didn't even think to question it. I do indeed have a 24v fan.

Thank-you very much for the replies, 2 days of being concerned about how to do this and it was all because of a false assumption, hooking it up to the pins pointed out by ultiarjan had it working perfectly in seconds, I feel silly now

[How to connect the heatsink fan for E3D v6 hotend on Original+?]

Hey guys,

I recently bought an E3D v6 hotend(3mm bowden) to print higher temp plastics and everything has gone perfectly except for the last part where I need to hook up the small heat sink fan to the motherboard.

I haven't been able to find any instructions on how to do this as the fan is 12v and the supply is 19v(white motherboard, the UM2 version if I'm not mistaken). Is anyone able to provide me with an idiot-proof set of instructions to hook the fan up so I don't damage the fan or MoBo?

Thanks.

[Visible lines in first layer and bubble-like indentations?]

70C is quite high and higher then the glass transition temp of most PLA's

the default temp on UM2 is 60C and I also print at 50 all the time.

You can also get those bubble marks where it doesn't stick, you can see it peel up as it goes over those points when printing the first layer. maybe where you touched it or oil dripped on it. A good clean with Alcohol may help.

 

Thanks for the info, It's in the middle of a print at the moment but I lowered the temp down to 55 before it started to see how it went.

I'll give it a clean after the print finishes, thanks.

[Visible lines in first layer and bubble-like indentations?]

Hey guys,

I printed out a case for my phone to see how well the printer was handling large solid layers, I've tried searching for the problem myself for a little while but the answers I've found seem to be contradicting themselves.

I're read that the fix for the lines is getting the print head closer to the bed, but the answer for the bubbles is to raise it.

Here's a picture of the print in question:

The bottom left corner is super smooth line-wise but it does have a little bit of bubbling.

PLA at 50mm/s, 205C hotend, 70C bed. I've seen a couple of places say that 70C can be too high for PLA and yet a lot of people say 70 is recommended so I'd love some clarification on that.

Thanks.

[Solved Print bed lowers itself WAY too low at start of print]

 

Maybe you should reload it (UMO+, not UMO in Cura!).

 

Yep, if this is a "fresh assembled" printer - upload the correct firmware with Cura and don't forget a subsequent "Control" -> "Restore failsafe" and "Control" -> "Store memory" (on the UltiController).

This will set the correct values for steps/mm (amongst other things).

 

Seems like the Restore failsafe and store memory fixed it, now I just need to work out the new problem of why the extruder is grinding against the filament and not feeding through the bowden tube. Thank you very much guys!

[Solved Print bed lowers itself WAY too low at start of print]

Hey guys,

I'm having a problem with my first ever print where at the very beginning it auto homes perfectly fine then it will lower the bed significantly, raise it a little bit again and begin attempting to print in mid-air (I have the filament retracted WAY back to stop it going everywhere while testing).

I have the same result whether I print directly from Cura(v 15.04), or if I print from an SD card in my controller.

Here is a video of the problem: Dropbox

And here is the start of the G code.

Any help would be greatly appreciated, thanks.

[Print bed only goes down]

But if you home it from the controller it should go *up* to home, not down.  If it's moving the wrong direction then one of the motor's wire pairs could be backwards (check wiring versus the other steppers) or you have the wrong firmware or something like that.

 

That's what I  mean, through the Ulticontrollers auto-home it raises correctly, but through Cura it doesn't. I'll be home in 3 hours to do more testing with Pronterface, it seems like it's just an issue with Cura.

[Print bed only goes down]

Either it *always* goes down or the directions are backwards.  Hopefully the later.  Let's figure out which and then fix the problem.

To figure out which you need a way to move it both up and down and see if it's backwards or if it always goes down.  There may be a way to do this in cura or from the ulticontroller - not sure.  But if it were me I would try pronterface.  It's a free download here - you connect to the printer with a USB cable and move it small amounts - you don't want to break the glass.  1mm or 5mm is plenty:

Once you know which (always down versus backwards) I'll tell you what to do next.  Also please mention what country you are in within your profile settings as parts and other things depend on the country.

 

While using the bed levelling wizard in Cura, if I press either of the up or down buttons it always goes down and by an amount much larger than what I told it to, yet this morning when I was fiddling with the Ulticontroller for a few minutes before I left for work I discovered that its auto home option raises the bed just fine(actually a bit too high, need to lower my Z switch, whoops), which leads to the assumption that it's something wrong with my Cura install, not with the printer.

I'll give Pronterface a try when I get home tonight, cheers.

[Print bed only goes down]

Hey guys,

Last night I finished assembling my Original+ and plugged it in to start calibrating it, but when I fired up Cura and went to calibrate the Z axis sensor the bed just dropped several centimetres every time I pressed a move button, regardless of if it was an up or down button. I don't think the motor is struggling because when I pressed the up button while applying upwards pressure to the underside of the print bed with my other hand it forcibly pushed my hand downwards.

I'm at work at the moment so I can't provide a video or pictures but I thought I'd ask before I leave for the trip home in case anyone knows of this issue and/or how to fix it, if not I can start answering troubleshooting questions when I get home.

Edit: Thought I should add, I'm using Cura 15.04 as recommended for first time setting up the printer.
