First good print!

Hello Everyone,

I got my robo 3d a few days ago and just started getting good prints from it... but only when using Cura not so much on Slic3r which i dont understand why...

The only issue i have at the moment is that it doesn't seam to fill in the gaps very well... I have attached a photo of a cookie cutter i printed and it has lots of gaps that have not been filled in... otherwise everything else is fine

my guess is that its something called the infill settings but i didn't want to mess around with it just yet, here is a photo of my print.

Super happy with my printer! value for money!!!

Cheers

Looks like you're having some under extrusion issues.

Can you measure your filament flow rate is accurate?

Heat up your nozzle and feed in filament. At the entry point to the cold end mark the filament. Then extrude 20mm or so. Mark the filament again and then pull it out. measure the distance between marks.

 

Also, what temperature did you print that at? If that's the blue PLA that came with the printer, it looks like it got printed at around 175-185 maybe? If so, try a higher printing temp. I found 195-205 works well for the blue they sent with the printer.

 

thanks so i worked it out.. it was just the infill was set to .25 and i wanted it at 1

So now I'm getting the prints i want... i have started to get some black goo leaking onto the prints and making them look burnt, not exactly sure where its coming from but looks like its where 2 red cables go into a cylinder / the square extruder head.

is this normal?

 

Nope not at all. Start a Tech Support Request

You'll need to remove your nozzle and see if it can be tightened or if there's a bigger issue like a cracked PTFE tube.

 

thanks, i will open a support case about it.... I wanted to change the head to an e3d but I want to wait and see how the printer runs for a few months before changing stuff....

so hopefully they can solve my problem.

thanks for the support, really great community here!!

 

So i got first contact from support and sent them some photos... my heated bed stopped working which was strange... it was also really hard to remove the connector and then finally when i got them appart i figured out why...

The connector had actually burnt on the inside and fused the plastic together.... so both connectors (controller board and bed sides) are now black and burnt on one of the pins... and not making contact.

I am waiting to see what support say, i am tempted to cut and use the molex connectors from an old PC power supply to fix it but am waiting to find out what they suggest i do before voiding my warranty....

 

well its been about a week now and i still have not heard anything from support... really disappointed with the reaction time on a printer which was about 1 week old when things started to fail...

 

cool, so I replaced the connector with the molex connectors from an old pc power supply all working great again... except the leaking head which i'm still waiting on a reply from support for...

so I got myself a XXL LCD from RepRap discount and printed a case for it which all turned out great.

the only other issue I have is the grinding noise the Z makes... its constantly squeaking and is really noisy on long prints..

 

Grease the threaded rods.

Mine was squeaking a deathly amount until I did that.

 

thanks, will grease them!

I have email them and its been a week since they contacted me...

 

Montravont, what did you grease them with? I was going to use a light oil, but wasn't sure if I needed to use something like white lithium grease?
