Cura profiles

[Martin Wynne]

.
As discussed on Zoom last night, I think perhaps a reduction from 190deg to 180deg would be better on John's Kingroon and maybe others. I had inched up from 180 to 190 in recent months without properly testing the results.

Here is the curaprofile for 180degC for timbering bricks in 4mm/ft scale (0.12mm layers).

please report results. thanks.

Cura profiles for 185degC and 190degC for timbering bricks in 4mm/ft scale (0.12mm layers).

all these profiles can be imported into Cura and chosen for use as required.

Hi Martin,
Do you have a similar start up script for your Elegoo Neptune 3 plus printer?
Is it basically the same, with only the name and then lines 11,12, 15 and 16 being more suited to that build plate size?
cheers
Phil,

Hi Phil,

yes, two. one for filing jigs, one for timbering bricks. most lines of the script need changing to increase the extrusion volume for the longer run. i'm intending to post them, and lots of other files, but i've reached my typing limit for today, it's just too painful. ask me on zoom, next ones 3pm and 8pm tomorrow.

p.s. i thought you said you had the Neptune 3 Pro not the Plus?

Hi Martin,
That's correct, I do have a Neptune 3 pro not a plus. if I am not mistaken my build area is 225 x 225 x 280 and yours is 320 x 320 x 400.
My question was talking about your Neptune 3 plus start up G code, not my pro. If I now understand you correctly the G code at start up would need more than the X and Y values changing, for the bigger bed plate, it would also need the E value calculation changing.
very happy to cover this off in a zoom.

I don't quite understand why the filing jigs or timber brick profiles, would have to be machine specific however. Are they not product profiles? or are you using a custom start G code for each type of product to do a specific measurement test?
don't bother typing a reply there questions for the zoom really.
cheers
Phil.

hi phil,

timbering bricks have the auto-level fade-out switched off so that the brick is constant thickness all over (but not necessarily flat). will be flat when fixed to a flat surface (baseboard).

rigid filing jigs have the fade-out at 5mm so that the top face is flat all over, for close clamping.

all the scripts have the power-loss recovery switched off, to prevent rapid wear of the microSD card. easily turned on if required by editing the script.

there is always more to everything than meets the eye, but typing it out takes ages -- and i doubt many folks will ever read it
