Great resource !!
So much common sense

Set up. Leveling and printing starts tomorrow.

Oh my !!!!
No setup problems, first print on the bed now, not sure why I need a butterfly , but I’ve got one coming . Sweet machine, ZERO issues , can’t wait for some good parts, inner fenders will be a start.

It's awesome when they print well out of the box. If only it were always that easy. :mrgreen:

You'll find you don't need rafts with prints like this.

Let's see the finished project when you have it. I imagine you're putting that butterfly on your Harley. :lmao:

Which vehicle are you making inner fenders for?

I’ve got a list of parts for the Wraith , but want them in PTEG, so I’m going to play and practice with PLA first. First issue was prints starting in corner not center, that was one click in CURA.

Cura has so many freaking options that it's dizzying at first.

 

[mikemcE]

What got me was I needed to “uncheck” the center box. The factory prints are perfect, I tried two other random files and they started in the corner until I changed it.
Good news the butterfly is smooth and crisp

Been playing for a week now. I’m starting to get all the settings correct now, PLA works well for me, but I need PETG. So test, test, test. Close, but not quite perfect, bit of stringing and a few blobs, but strong .

Do you have to coat the print bed with anything like hairspray to help the base material stay in place?

 

[mikemcE]

No not so far. I run it heated at 70 and PETG sticks just fine. Almost too good. I am getting some high spots that acetone isn’t cutting, need to go glass plate soon for PETG.
Printing PLA is a dream on this machine, right OOB

Those prints look really good.

I have been practicing printing with a large format extruder so that I can eventually print large parts like a custom flatbed.

In the video, you can see the printer laying down a single extrusion shell in a tall model vase. Finished model is 6 inches tall.

PETG from what Im learning more of ... needs to be printed slower, hotter and with the head a bit higher up from the bed. Also not cooled as much during the print. It doesnt need to be squished down like PLA and layers stick together better if they are still close to their print temps.

If youre still shedding stringies you could try slowing the head down or turning your fan down. Im at 75% right now but gonna try dropping to 50%, I get some layer splitting. Also restraction can help too with getting rid of the hairies/stringies.

The vase video is perfect .... you can see it laying down the strand and not squishing it. IT actually makes me want to print one tonight as a good test for what Ive been trying. "thumbsup"

Im printing on 3M blue tape and just use the glue sticks I get from the dollar store, 3 sticks for a buck. Last time I stocked up the lady laughed and said her office meetings usually required the same thing lol.

Glass Ive read a lot use good old fashion Aqua Net hair spray .... you know the Ozone depleting stuff :ror:

 

[mikemcE]

Yeah 245 at 50 seems much better, the fan is not shrouded, so mine is at 100. I’m getting better, but practice will make a difference

Those prints look great! The Monoprice printers are highly underrated.

PETG can be difficult to remove.

I hate printing with rafts, but sometimes it's necessary.

 

[mikemcE]

I too hate rafts, but with PETG the prints are much better, so it’s worth the extra time and materials. PLA doesn’t seem as finicky , no raft or brim needed.

It took a bit of practice to get it right. With PETT you want high layer heights so that the finished print is transparent. In the vase print, the layer height is the same as the diameter of the nozzle so there is not flattening of the layers.

I practiced doing prints of 3DBenchy until I got perfect prints then I moved on to the vase.

Good tip.

I would think no flattening means the resultant print won't be as strong though.

That is is true. With the layer having a round profile on top you get less contact between layers and less strength. I traded off strength for maximum clarity which is ok in a vase.

If I was wanting a stronger print I would use a lower layer height and more layers. But the plastic would have a cloudy look to it.

Another factor is the plastic being used, since PETT is "sticky" when hot, you have a higher layer height and still get bonding of the layers.

A nice thing about 3D printing is you never run of things to learn due to all of the different options that are available.
