Unresolved Bad Printer.

ignore my posts. I am looking at the cork thinking the heater is the same size.

 

I definitely have a leaky extruder.

I can't get that dam wrench on the nut even when its heated and all gooey. I am going to have to pull the fan to get on it and I have to watch that the heat dose not get to high as the rubber boot is off and the thermal sensor is of the heat block.

 

Check out how I cleaned my hexagon after a leak. You might also want to read my whole printer thread. Welcome to the learning curve.

When did you receive your printer and from what supplier?

You should clean off the filament and tighten down the nozzle.

 

Direct from robo 3d. That is where I am having trouble, is tightening down the nozzle.

 

How long have you had it exactly?

You need to remove the black silicone boot to expose the nozzle. Clean off all the leaked out filament using a bristle brush or similar.

On the heat break there's a 4.5mm slot and in your tool kit there should be a 4.5mm wrench.

Heat up the hot end to around 280C if it will let you, otherwise 240C will work fine. Then using a 7mm or adjustable wrench grip the flats of the nozzle and tighten it down. Ensuring the nozzle is not seated against the heater block.

2 days, 3 hours.

 

Thanks. I'll have a word with them about this. Lemme know if you're able to get it tightened down

 

That's an interesting looking fan shroud/holder btw. Anymore pictures?

 

Just the stock fan holder for the R1.

 

Yeah they like to change things without telling anyone.

I got it all clean up, tightened down the the heater block, and printed a few test prints. Everything looks good now, except the rubber boot which has seen better days. I need to do a larger print to make sure. The Z axis rods are vibrating against the Shroud now and I am wondering if I might have loosen something? I only worked in the print head area, and did not touch the Z rods. Anyone have any ideas on how to tighten them down or eliminate this rattling?

Thanks,

 

Mine did the same thing. I used paper wrapped around them jammed into the openings at the top of the rods. No more chatter.

 

Uh Not entirely sure what could have caused that. Got a picture/Video?

 

Heres mine. Its not a lot of paper but just enough to stop the noise.

 

My first robo had no bushings for the z rods... I returned that one and got another that had been either reconditioned or uphraded in house. It had bushings in the housing, but they fit for crap. Loose enough that i used a stick of filament jammed up in there to quell the movement. Good and bad... It did nothing for my x/y ghosting. Mist be in the bearings.

Yea, while typing you posted pics. Youre "missing" the bushings mine has... Simple printed junk, but its better than that.

 

If that's what he means, here's a part you can print to go up there:

Should stabalize it nicely

 

Sweet there really isn't much paper there are the bushing super thin?

 

Mine are... Same housing as yours... Just has some uber low res printed bushes in there.
