I've Gone and Done Something Mental

[ajlelectronics]

Even the e steps for the extruder needs to be checked as this can also cause problems. You may need to change the z offset to print petg successfully

Which way?

 

[Pete.]

Which way?

Print a test part, measure it and adjust. I did a 20mm cube with a 12mm hole through it or something like that.

$213 each! There is an aftermarket one in america at $40 plus import costs and carriage, so this one looked interesting. Maybe I should try a PLA version initially. @MattF

If it’s a funnel for a job, have a go at printing in PLA, you’ve nothing to loose

Yer that is taking the proverbial. Probably about 21 Euro in Latvia with the BMW part number and logo melted off using a soldering iron. (Going by what I paid for the plastic trays and ducting for under my E61 )

I’m not at my pc now but think the nozzle needs to be a closer the bed for petg and bed temp needs to be higher

The iABS modulator is not something I am prepared to risk contaminating. They are hellishly expensive and even a rebuild service is expensive, where available. I would still need a funnel to refill it!

The funnel is required because the wheel control circuits have no real reservoir in the modulator. So the funnel gives a reserve of fluid during flushing.

Ok, that gives some more context, and here endeth my knowledge of mechanical things

 

[carbon]

For petg I have the nozzle 0.05mm closer the print bed

@ajlelectronics Wouldn't somewhere like Lakeland have a suitable kitchen funnel that would suffice, even as a 'one-off'?

An hour and a half later and no sign of deterioration. The dot4 is still crystal clear, no change in the plastic and it's still 4 thou.

TBH if this doesn't convince you that your fears are unfounded I don't know what will. Especially since the pic above seems to show that someone has used JBweld to make a dam for their make-shift funnel extension. Now THAT would definitely have me worried about liquid JB dripping into the hole while it cured.

It's not just a funnel John, it terminates in a screw thread that seals against the iABS modulator with an O ring. You can see in the photo that someone has "made" something, but we are talking about over a Grand's worth of kit here.

Interesting experiment, I am grateful for that. Being new to all this, I could only accept what was written in the item description.

Ah, gotcha. Could you buy a funnel and turn an 'end fitment' from delrin to be glued onto the end?

 

[Parm]

Well, I’ve had a new problem. Filament randomly snapped yesterday and ruined a print.

no issues, just get it fed in and start the print again,only I managed to get the filament tangled up on its self on the role. It’s nearing the end.

worked fine for a few hours then started to get tighter and tighter and ruined another print

All fixed now

Do you want me to attempt to print one in PLA? Christ, you're more indecisive than a woman at the moment.

Whomever said PLA was unsuitable may have been referring to long term exposure.

That would be very kind of you Matt, it may allow me to get one with the job! Let me know by PM what the cost inc carriage will be and I will Paypal it across.

Have you got a Friday afternoon printer by any chance?

Your well ahead of me in understanding all this sort of stuff, with me being a dumb ass with anything IT I’m getting on ok, I think

The only big issue I’ve had was entirely my doing by not securing the Z axis limit switch correctly

That is the way my luck is currently.

I'm not sure that I am any further ahead. I may have a larger waste bin, possibly! Currently trying to understand 3D CAD. Started with Fusion and that makes no sense whatever to me. Now playing with Design Spark and have managed to make a rounded edge rectangle with circles where I want holes to be. That is about the extent of a couple of hours work.

Once I start to get the hang of the printer the next mission is to start understanding 3d cad. No idea what I’ll be using but it needs to be simple

I had to use youtube tutorials to learn the basics of fusion. Thankfully for me I was nursing a sliced-up finger at the time so I couldn't get distracted by workshop duties or I might never have managed it.
