Quad Gantry Leveling values for a smaller size

[carmine shard]

Currently building a smaller version for the V2.4, how do I go about the QDL values? For example a 120mmx120mm bed, if I look at the numbers given for the 3 standard sizes:

`250
gantry_corners:
-60,-10
310, 320

points:
50,25
50,175
200,175
200,25`

`300
#gantry_corners:
-60,-10
360,370

points:
50,25
50,225
250,225
250,25`

If I continue the pattern, for 120 I get

`120
gantry_corners:
-60,-10
180,190

points:
50,25
50,-5
20,-5
20,25`

which obviously won't work as I would end up outside the print area. I guess my question goes more towards how exactly QDL works, would changing the values so that it measure something like:

`maybe 120
gantry_corners:
-60,-10
180,190

points:
20,20
20,100
100,100
100,20`

still work? I am not quite there yet to just send it and try, struggling with setting the configs up in general. But that thought just crossed my mind

What size voron are you using as your base? Like a 250 frame with a 120x120 build plate?

or you sized everything down?

[carmine shard]

I scaled down everything

[wicked quarry]

so like a V0 sized V2.4?

[carmine shard]

Based on the scaling of the other sizes, it seems to fit

yeah

Slightly wider, they are next to each otehr

I am getting closer to the point of just trying it out, just got some other issues with the homing right now. I looked for configs of other small custom builds and I couldn't find any (like 150mm bed size)

[wicked quarry]

Maybe go a little undersized and test it out....

What you trying to achieve? stiffer frame?

[carmine shard]

You mean with the build or QGL? Build wise I dislike my V0, only problems, small screws, not really Voron like. I expected a non compromise printer and got a lot of compromises. Also why not lol. QGL because if it's an option why not use it ^^

The electronics will fit inside, just have them dangerously outside for now as I can't print the mounts yet

[wicked quarry]

Manta8 with the CB1 onboard?

[carmine shard]

yeah but the V1.1, I bought the stuff back in april last year and just didn't find the time

[wicked quarry]

yeah... i just got my old ender S1 running klipper just to play with it and the QGL really spoiled me

[carmine shard]

When you have to start using paper to level the bed again 😂

[wicked quarry]

I mean... I only had it for two months until I ordered my 2.4 kit..... completely forgot the hassle

yeah.... and the only space I got for my S1 is under my 2.4.... got limited space on this work boat so it gets to sit 4 inches off the floor...

so.... sitting on the floor and adjusting the leveling screws is going to be a PITA..... be nice to be able to use the S1 for smaller prints while the 2.4 is chugging away on some larger projects.

sounds like someone needs a 120x120 V2.4, now there is an excuse to source the parts 😉

[gaunt wharf]

have you considered looking into the Micron? it's essentially a mini 2.4, they have a 120x120 build size option, at the very least it might be a good source of reference that could apply to your project? https://github.com/PrintersForAnts/Micron

[carmine shard]

They do have a config with commented gantry values, I'll check them out in a few hours just finishing up the probe

[carmine shard]

gantry_corners:

-60,-10
180,190

Probe points:

25, 0
25, 70
95, 70
95, 0

These values work
