[Printing big thing problem]

Try 1.2mm layers or more heat or print slower

 

[Stepper Drivers + Potentiometers]

I've put mine in back to front too. It only killed the driver. The new pololu drivers will come with a heat sink.

[Strange effects on falt surface]

More fill would help. But definitely you thin top/bottom is the problem. Your fan running at full will help.

Mine doesn't fill enough on the top layer till 0.6mm when I use 10% fill.

 

[Stepper Drivers + Potentiometers]

Polulu drivers work. Drop in replacement as far as I know. I've replaced a few of mine.

 

[Slicing of multiple objects in Cura?]

Click on File then Preferences and then set dimensions for the Printer Head size. Sorry I don't know the defaults.

This is the pen someone else was using

[PCB Modification Question]

I thinks it's more feasible to make a pen plotter for your UM and get a suitable pen for the job. Check out Thingiverse, It's been done like that before.

 

[Printing with LayBrick]

Good one Simon, Thanks for the writeup.

 

[Aluminium heated bed questions]

Thanks George, I'll keep looking.

 

[Extruder motor stop/clicking noise]

Hi

If it turns initially then possibly the Pololu driver is over heating

Have a look at it and see if the heat sink has come off or the fan underneath is not spinning.

After that look up in the wiki how to adjust the trimpot on the Pololu driver

 

[Aluminium heated bed questions]

I couldn't find MIC6 aluminum in Australia.

Anyone know where/how to get it or similar from here?

 

[RepRap Alu-Heatbed MK3]

I think it would be good providing it is flat enough. I have glass over a MK2 heater at the moment but find the edges are a bit cool so aluminium would spread the heat better I think.

 

[E3D All Metal Hotend for Ultimaker]

What's your retraction speed Nick. I recently noticed mine wasn't always pushing back as much as it retracted. The motor would squeal and it must have been missing steps at that point. So I backed the setting back from 45 to 30.

 

[New Cura NOT giving 100% fill density.]

Look at the picture in this post (the 5 cubes) carefully (zoom way the hell in) and read all the text associated with the pictures:

http://umforum.ultimaker.com/index.php?/topic/1872-some-calibration-photographs/?p=14396

Then read 2 posts below that with the diagram explaining the issue of infill not touching edge.

 

Thanks George, I was hoping you would chime in.

 

[New Cura NOT giving 100% fill density.]

an issue with the fill not touching the outer wall

 

I expert Settings you will find Infill Overlap (%) for this. Though you may have loose short belts or another problem which is causing the infill not to touch the walls.

There are many posts and pictures in this forum regarding this issue.

 

[Default microstepping settings and direct extruder]

My guess is x and y are 1/16 and z is 1/8.

 

Correct

I'm fairly sure the extruder is 1/16

 

[Help with my print. Need advice how to fix. new user]

You may have the jumper set for z to 16 steps instead of 8. That would cause half height but still extruding full amount

Hi Gman

From the looks of this print and the pic of your previous settings maybe your fan if off.

I suggest you reset your profile to default in Cura and then change your filament setting back to 1.71mm if that's what it measures to.

You could then also turn off the raft and try another print.

 

[Hello from Ukraine! Just share some experience.]

Yep it sounds like a sound from the belt. One of the Y belts in particular. You'll notice it always makes the sound at a certain point when moving in the Y direction. Can you take a video of each of the 6 pulleys involved?

 

[Help with my print. Need advice how to fix. new user]

Hi Gman

What's your printer?

 

[Post your latest print!]

Here is a print I did recently for a friend of mine, http://artbyglee.blogspot.com/ This was printed on my ultimaker at 60 microns. I posted a smaller test version of this a while back, this finished version was printed using cura 13.06

 

 

 

 

 

 

Looks as good as prints get. Well done.

 

[Hello from Ukraine! Just share some experience.]

I have some strange noise when printing, it is like tik-tick, tik-tick. Very strange cause cant understand from where it come.

 

I think it is related to the belts/pulleys.

Possibly a pulley is not properly in line with the belt so the side of the belt rides up on the flange and then falls down again. Maybe look for this or do a search on the forums for 'Strange noise' or 'strange sound'

 

[Prevent 'ringing' (wobbly surface after sharp corners)]

Great work Peanudt

Thanks for your efforts. I'll give that lowering acceleration a go. I've been printing at 60mm/s so it may make a greater difference at these speeds.

 

[Question re: heated bed build PSUs]

It may be a bit slow at heating at 130W and a bit too much current at 523W. So a variable PS 12-24V at 350+ Watts would be best I think and adjust the voltage to set the wattage at around 300W DC is probably better at such high currents.

 

[Question re: heated bed build PSUs]

You should decide which HBP to buy and find out what power it consumes at what voltage.

Then buy a PSU that supplies that voltage and a wattage greater than that required.

The wires from the PSU to the HBP need to be thick and flexible.

Before you turn it on get an electrician or similar to check it over.
