[Is this under extrusion??]

I would increase the bottom/ top to 0.8 (or more) and you could easily increase layer height up to .06 - 0.10

you don't mention your print speed ?

 

sorry the speed is usually between 40-60 mm/s, I've put at 40 mm/s for the next print

 

[Is this under extrusion??]

wow thanks for the responses. I have the original 0.4mm nozzle and I'm using the following settings:

Layer height 0.2, shell thickness 1.6, Bottom/ top 0.6, density 33%, Temp 210 (PLA), bed temp 55.

 

[Is this under extrusion??]

any idea whats causing this? The other extruder prints fine

 

[Extruder 2 Doesn't kick in]

Thanks but it's only supposed to be printing in a single colour not switching. How do i set these offsets?

 

[Extruder 2 Doesn't kick in]

Sorry. I'll try again, try https://www.dropbox.com/s/wp8j478yv5um9rz/FanMountMk3.gcode?dl=0'>https://www.dropbox.com/s/wp8j478yv5um9rz/FanMountMk3.gcode?dl=0 one. Also https://www.dropbox.com/s/wp8j478yv5um9rz/FanMountMk3.gcode?dl=0 is how the print came out. Pretty poor.

 

[Extruder 2 Doesn't kick in]

Sure. https://www.dropbox.com/s/dgjs3jiwwfnbkcw/G-Code.ini?dl=0 is the G Code. Thanks

 

[Extruder 2 Doesn't kick in]

Ultimaker? Any advice?

 

[Extruder 2 Doesn't kick in]

Hi. I've got my original with the dual extruders built both ends are heating well, but it's running horribly. During the first print I could only get the second extruder to work. i.e. I selected the first or the second extruder but only the sond extruded.

I've tried switching the cables, and updating the firmware but neither worked. Then I aligned the bed and removed some of the cable ties I've put underneath to sort the birds nest and the next print came out like https://www.dropbox.com/s/3nbrztu2zrkg4fk/IMAG0218.jpg?dl=0 (using both extruders).

The next print (using only the second extruder) started printing with extruder 2 then randomly switched to extruder 1, and is looking like https://www.dropbox.com/s/oga3eo3ml9alsyi/IMAG0219.jpg?dl=0 so far.

Is possible that the signals are jumping between the wires? Or it is an issue with Cura?

 

[No Extrusion at all]

Hi guys. Iam having a problem with my ultimaker original, no material is coming out of either of the extruders at all.

 

• Both the extruder wheels are turning and I have seen bite marks on the PLA.
  
• Both the extruders are getting up to temp
  
• The bed is level
  
• Both extruders are level
  

 

Does mean that something is assembled wrong in the hot ends? Do you have tips on what to look for?

Update: I did get a bit of plastic out of extruder one but that is all. It wasn't enough to print it and now there is none again

 

[Calibrate dual extruder with heated bed]

Solved it by printing a z axis adjuster on works ultimaker

 

[Calibrate dual extruder with heated bed]

Hi guys do you have any tips on calibrating the dual extruders to the heated bed? I assume you just do as the wiki says except you don't adjust the 4 corners you use the 3 adjusters?

It is being hampered by backlash in the z drive causing the bed to drop just beyond the limit switch. Anyone know how to remove the play in the Z axis?

 

[Extruder Issues??]

Hey Chris. I'm printing PLA at 210 with the bed at 70. The layer height was 0.2mm. Whats the automatic method of cleaning the nozzle?

I had a look at works' Ultimaker today and the extruder is a lot tighter than mine.

 

[Extruder Issues??]

I've got the machine running but when I do a print it puts the raft down and then nothing (it just goes through the motions without putting any material out - the extruder wheel is turning but the spool isn't moving). I already had to take the nozzle to work and clear it using a gas axe/ blow torch. Isn't there a direct support phone line at Ultimaker. The emails can take weeks to get back?

 

[Controlling without the Ulticontroller?]

Hey guys, just a quick one. Where is the options in Cura to preheat, and jog the table about without an Ulticontroller?

 

[Heated bed with no heat??]

Got it sorted, the earth wire was loose on the heater for the bed!

 

[Heated bed with no heat??]

Sounds like a bed issue indeed.

Does the bed actually get warm? Does the red LED on the electronics turns on when it wants to heatup?

Thanks, no the bed is at room temp, sure I can see a red LED behind the green ones.

I guess that means I need to check the wiring on the bed. Is there any known areas to check after assembly?

 

[Heated bed with no heat??]

Me again! I've built the printer and levelled the bed, but when I print something, nothing happens. Cura says its printing and that temp is 19, and the bed is 16 but then nothing happens and the temp doesn't change.

It worked ok before with the bed levelling and material loading. So I guess its a bed issue?

 

[Heated bed alignment]

Thanks, I held it the way you said. It worked a treat!

 

[Heated bed alignment]

Sorry, I don't get it. How can it move without rotating the lead screw. Do you rotate the screw so it travels from the botom to the top of the machine for each screw on the bearings?

 

[Heated bed alignment]

Hi there. How do you wind the bed up and down when you are aligning the 8 screws, you can't tuen the thread without damaging the motor.

The instructions say to move it all the way up and down, does it mean to compress the springs by hand?

Also where the bottom limit switch for the table????

Thanks if you can help

 

[Ultimaker Origional + and dual extruders]

Is this what's required? It seems to show
