Edges lifting – Cessna 152 Trainer  

Re: Edges lifting – Cessna 152 Trainer

You can try to squish the first layer a little better by adjusting the Z-offset with Live Adjust.

Or you could use a brim with 10 lines or so, in S3D its on the additions tab.

What material are you printing in?

Sorry, should have clarified. I am using the Prusa PLA (Silver) that shipped with the printer.

As soon as this print completes I will see if I can figure out how to adjust (increase) the brim size.

Thank you!!

10 lines should be more than enough if the brim is in direct contact with the part.

If that doesnt work try setting the nozzle height lower within the printer (Live Z adjust), not too much that it will drag itself across the part on the first layer.

What temperature are you using on the Bed?

Re: Edges lifting – Cessna 152 Trainer

What temperature are you using on the Bed?

The bed temperature is 56 degrees and the heating element is 230 degrees; both of these settings were pre-configured per the Simplify3d Factory files provided from 3D Lab Prints for best results.

The only difference is they indicated they use the Prusa i3 MK2 where I have the MK3 model. When I installed Simplify3d there wasn't an option for the MK3 model so I selected the MK2. Didn't think it would make much of a difference.

230 for the Hot-end is way too much for PLA....

And the bed could be a little higher....

Use 215 for the hot-end (first layer), then 210º for the rest of the layers, the bed you can use 60º.

Me personally, i use 210º for first layer and 205 for the rest with Prusa PLA.

It looks like this print is nearing completion. As soon as its done I will see if i can figure out how to adjust only the first layer, etc as you have mentioned. Hope you're ready for more questions! 😉

Re: Edges lifting – Cessna 152 Trainer

I think in Simplify3D in Under HELP/Configuration Assistant you could reload the new profiles and I think the Prusa then MK3 selections are now available. Doing this may erase or mess up any special profiles you may have already made.

Re: Edges lifting – Cessna 152 Trainer

Okay, I have adjusted the settings as I think you're suggesting. I have attached screenshots of the original settings and the changes I have made.
Do these appear to be correct?

Unfortunately that is not the case. There is an i3, but that doesn't specify the MK2 or MK3.

Re: Edges lifting – Cessna 152 Trainer

Hi Kerry, there have been suggested S3d profiles offered on the S3d section of this forum. you could try loading them when you have time...

in the mean time 230 is high for pla, so what is happenning is that the pla is shrinking more than normal, as it cools, resulting in the warp you are seeing.

typically, the longer the length of your print, on the bed, the higher the temperature of the bed to reduce warping, with a max for PLA of about 60degrees...

Joan,

Not sure what thread you're referencing above?

Okay, so I was able to adjust the HE for the first layer (215) and all other layers to 210.

Not sure why, but the heat bed never went above 56 even though I configured for 60.

Any ideas what I may have been doing incorrectly?

Oh, and I should note, this job thus far has not lifted on the ends.

Hi Kerry,

Those settings look good =)

Let us know how it goes.

Regarding the Bed temperature. You may need to adjust the PID of the heated bed if its not reaching the temperature it is set too. If you put 64-65C does it reach 60?

I have done it for the Hot-end, but not for the bed since mine cant reach the set temperatures fine and it stays there. I guess it should work just like normal and you can use the Gcode command M303...

I have no idea why they didnt include the PID auto-tune for the BED on the printer since you can do it for the Hot-End...

Can anyone confirm if the M303 command is working on the MK3?

I may have downloaded it from another source first.

Re: Edges lifting – Cessna 152 Trainer

Once the print starts, you can modify the bed temperature under the Tune menu.
