Whatcha Printing?

[Hammer Down]

Pat is very sadly no longer with us. Taco was what he named that truck after doing that to it. You can check out some of his run vids with it here.

Did he pass away, or just quit visiting the forum? I was thinking about him not too long ago..

Nobody has found out for sure as far as I know. But he was battling throat cancer I think it was, and he wouldn't have abandoned us if he had won that fight.

Any idea why I'm getting this buildup in the print on these fine corners? Wings of an airplane toy.

Is that where it is starting each layer? I am guessing it is, and if so, it is likely due to retraction and/or your coast settings not being high enough. As it lifts in Z for the next layer, it could be still extruding filament. My son is on the 0C right now for school, so in a little bit I will go look at my settings. Let me see your settings in the meantime. Screenshot every page of settings if possible.

Also, show me a screenshot of the toolpaths. Zoom into those problem areas.

I thought it might be over extrusion. The z seam should be on random.

Oh, I was actually seeing something else. The pic is too blurry to see anything very well.

This is where the wings start to come out. Should be an easy overhang as it's not an extreme angle. Maybe the cooling is too low and then petg is staying too soft?

Have you calibrated your extruder?

 

[RetroThutmose]

Have you calibrated your extruder?

I have not. Was just watching some content on how to calibrate by measuring the filament on a 50mm extrusion command

Do that and set your extrusion multiplier. It is best to do that in the firmware if you can figure that out, that way in your slicer your multiplier will stay set to "1", with the occasional adjustment for different filaments.

Also, calibrate your hotend and bed temps by way of PID tuning.

For the hotend...

1. Access the Touch Screen: Navigate to the printer's touch screen interface.
2. Find the Setting: Go to Settings > Advanced Settings > Nozzle PID detection.
3. Start Calibration: Click the "Start" button to begin the automatic PID detection process.

For the bed...

I had noticed some crappy looking edges on an attempted print, so I decided to go through and adjust tension on all the belts on the A1, then run a calibration. It seemed to solve what I was noticing. I was having bed adhesion issues with the overture easy PA/nylon. Nothing would stick on an absolutely clean plate. As I was watching it to see why it was having problemos I kept hearing crackling as the filament was being extruded. WTF, I keep all this chit is a sealed bag with desiccant pouches. I put the roll in a dehydrator overnight and will try sometime today.
I am trying to print some door hinges for the Kei Truck.

Designed & printed some hangers for my planes, mainly to free up shelf space!

Just a "claw" that pops over the top wing joiner, 2mm pushrod wire bent into a D-ring

This one slips over the pegs for the rubber bands and also does the job of holding the wing on.

Both hang the plane over its center of gravity so they sit level.

And, final results with the landing gear covers:

Not exactly historically accurate, more like the covers some carrier planes had, but the fit is so satisfying.

I just printed this snake skeleton for my daughter. It's got a lot of clean up to do. Is an exacto the best way to go about that or is there something else that would work better?

I use flush cut pliers more than anything.

That would work. It's these little pieces I'm working on that made me wonder if there's a better way.

 

[WickedFog]

Yeah, cleaning off the outer edges on the bottom is always a pain. When I design stuff, I always model in at least a .6mm chamfer there. It helps prevent that.

That's a great idea.

The pliers and a torch worked like a charm. Much faster.

FYI fellow print nerds!! Hobby Lobby now sells filament! For me, it's the only brick & mortar location to purchase filament within a 2-hour radius. Microcenter is the other.

It's cheap too! $12.99 for plain color PLA and $18.99-19.99 for the specialty colors. They have a really cool looking marble PLA but I only have one nozzle at this time and I'm not trying to clog it up until the replacements come in.

I sampled the plain black PLA and the black/pink silk PLA. They both printed perfectly well.

Sample of the black/pink:

Dialing my machine in to print one of those M-jet boats. Looking good. Set my z offset with a feeler gauge, OMG it's way more accurate and easy. I was way off using the paper method.

That looks good dude.

I only ever use the paper to get me close. Then I have a test print that prints single lines in squares working from the outside in, every 25mm or so. I fire that up and level the bed on the fly. Best way to dial it in.

Watch that feeler gage doesn't damage your tip. Some of the tips are pretty fragile, right on the tip.
