Re: Filament Run-out Sensor Install Problem

Postby kencfii » Tue Aug 28, 2018 5:12 pm

Hello again,
So I did get my sensor working properly as I mentioned in previous posts.

I did print the new back cover and it does align better but does not seem to stick tio the case very well - not really enough contact between case and the new plastic design - so the sticky tape can hold firm - but it is still better.

Have to say that "johnsays" is correct - this does not really fix the problem. The filament still grinds and makes a horrible noise as the filament is feeding especially if the heads move across the entire build platform. There is just too much drag on the filament because the holes are not beveled (or whatever) it is just a sharp contact point. This printed prints so smooth and quiet and the sensor ruins all that and causes a lot of drag. I need the sensor because big prints need lots of filament but man this is not good...
Please tell us if it is possible to fix this.....

Such a quality printer then this comes along....

any help???

As I wrote before. This is how to fix it.

JohnSays wrote:I want to put paid to having to print a new filament cover. It doesn't fix the source of the problem. The source of the problem is simply that the holes that the filament enters are not chamfered. That's it. The edges are so sharp there that the filament hangs and scrapes. While printing a new cover aligns the filament better, it doesn't chamfer the holes. With chamfered holes you do not need a new filament cover.

Thanks John I saw that and hope to do what you say - in fact I just ordered that bit :-)

Just wanted to get Raise to be aware and see what they say - You seemed like a lone wolf here and I just agree so much wanted to get some more push behind a manufacturer fix...

Thanks and Print on!

Cool! I appreciate that. I don't understand the push to print a non-fix fix.

You know its a genuine Raise3D product when you have to disassemble, redesign, and fabricate your own parts in order to make it functional.

Then I have the genuine product! I also put in the work to adjust the whole thing. I didn't have a drill bit with the right size so I only used a slightly bigger one for the top part, I didn't have the nerve to drill the delicate part with that where the sensors are placed (I disassembled it first of course). I used a smaller bit to try to get as much room as possible. And I chamfered everything.

I also printed a new housing, I changed the Raise3D design a bit. The bottom parts are removed as I think this should go in the filament bay and not on the print head. The file is here: https://www.thingiverse.com/thing:3099649
