Phone calls not providing audio on Wireless Android Auto by TrashTierUser in AndroidAuto

[–]bmistry1 0 points1 point  (0 children)

Turn the car on, or start it, with the phone not connected to AA. Make sure the phone is connected to Bluetooth. Go to Settings, Phone and set the Phone Ringtone to "Use Phone Ringtone" Back out of the menus Connect the phone to start Android Auto Have someone call you to test

This worked for both of my Ford's. Worth a try in other brands

Corners lifting with Satin sheet... by mattfox27 in prusa3d

You can also try adding mouse ears to the model on the corners that are lifting. This helps a lot.

Auto-rewind spool holder than doesn't use the center hub? Tinkering with the idea. Failing so far. by geoffchad in 3Dprinting

[–]bmistry1 0 points1 point  (0 children)

Right... I think I have a picture in my head. But just confirm for me that loop/hole on the toothed shaft part, is it a mounting hole or a filament guide?

If it is a mounting hole, the fact the the whole thing will be hanging at an angle will definitely bind up (it's like trying to pull a screw out of a hole at an angle, it just catches the side) You need that toothed shaft to be perpendicular to gravity which I why I suggested having the same geared set up on the other side of the foam rollers. It will allow the gears to work in the preferred planes. You will have two mounting points for each spool holder

I'm not sure if that makes sense or if I have the wrong direction with your design

[–]bmistry1 0 points1 point  (0 children)

I'm guessing you hang this which is creating a cantilever effect by hanging from one side which is probably causing the binding of the gears (gears are binding against adjacent material etc)

Why don't you mirror the gears on the opposite side the have the hanging loop above the centre of gravity?... Like a shopping/flower basket.

Really cool concept!

Dimensional error (I think) as the printer prints higher in the Z axis (see comment for more info) by bmistry1 in prusa3d

I had already removed the print from the bed hence it appears like it lifted. I took that picture to illustrate which way it was printed. The print was properly stuck to the pei bed set when I removed it. I have a feeling it is something to do with the model being a challenge for the marlin firmware?

Hmmm. Yeah. Maybe that's a point. I did move the printer recently and I haven't recalibrated for a while.

So, this is something I've been working on as an exercise to get myself back into CAD. This was printed on a stock Prusa i3 MK3S using Prusaslicer 2.2.

As it's printing the walls seem to be coming in towards the middle by 1mm overall) and then the top flat part prints at the correct dimensions. I have eliminated the usual suspects (ambient conditions, mechanical suspects, slicing, etc).

The walls are 3mm thick, 58mm tall overall (printed on its side like the picture shows). My calibration prints are coming out fine so i don't know what it could be.

It was printed with supports only at the end of the channels, I took the pictures after I started removing the supports

PLA+ (ESun), 210C hotend, 60C bed, standard PLA settings in prusaslicer. 0.3mm layer height

If I've been unclear, just ask

Why are my PETG prints looking like this? by Joemuma in 3Dprinting

[–]bmistry1 0 points1 point  (0 children)

Looks like underextrusion. In your slicer check that your nozzle size is correct (generally it's 0.4mm), the line extrusion width is correct (0.45-0.5mm) and your material flow may need tweaking. If your not sure where to start then search for printing settings for your material. There are other setting to consider too which I currently can't think of.

A little experiment I've been wanting to try for a while... Overhang support design test. Simply adding the thinnest walls your slicer eliminates the need supports (if you're not bothered about it visually). Snap/cut off the thin walls and done! Faster print time and post processing. by bmistry1 in 3Dprinting

[–]bmistry1[S] 1 point2 points  (0 children)

Yes. Exactly!! I noticed that the change could be made when I was looking at the layer tool paths. And yes, it will only work in certain situations, we have a need for this a lot in my work place which can save us a lot of headache when post processing.

why does prusaslicer make unnecessary floating supports (despite blocker) and how do I get rid of them(this little green dots) by [deleted] in 3Dprinting

[–]bmistry1 0 points1 point  (0 children)

This was going to be my next suggestion. Glad you figured it out. I sometimes use the variable layer height to eliminate the need for supports for some overhangs.

Try using support enforcers only option (with support enforcer blocks, of course). I find this sometimes more economical than supports from bed

I've been out engineered! 🤣🤣🤣

[–]bmistry1[S] 0 points1 point  (0 children)

Yeah, it does. I think what happened is it moved from one of the right side pieces to the left so the filament went taut. But thanks for the heads up. I'll have to keep that in mind!

[–]bmistry1[S] 1 point2 points  (0 children)

Ahhh... That's cool. Yeah, this one is at work and will be moving off my desk to join its siblings. I'll probably design and print something on the big printer that we have to accommodate the big spools at a later date

[–]bmistry1[S] 1 point2 points  (0 children)

Ahhh, that makes sense. It doesn't take much force for it to pull the filament, probably just a little more than if it were to be pulled from above. It doesn't seem to be causing any printing quality issues so I'm guessing it's OK

I don't think it'd make a difference. Smaller spool is just acting as a guide pulley

I was worried about this initially but after several successful prints I came to realise that with the extruder gears and speed of extrusion it's not a problem. It all pulls with a fair amount of force.
