Actual Build area vs Simplify3d

[adamfilip]

Im having an issue with my build area being different then what i see in simplify3d
I have set the sizes in S3D to be the same as in marlin
but clearly something is wrong. not sure where to make the adjustment to get them sync'd

I am using Auto bed levelling and that does offset everything over, but i need too or the Z endstop will try to probe off the glass

thoughts?

Am having problem too with simplify3d. I can't seem to get it to extrude correctly for some sort of reason. Do you think you can share your simplify3d setting also I only have one extruder.

Have you taken into account the offset for your second extruder?

[adamfilip]

There is the probe offset. lets assume 10mm
the probing area is set to 240x240mm
the 2nd extruder offset lets say is 20mm

im not sure what i should be adjusting to take the probe and 2nd extruder into account to regain my print area back to 300x300mm (or atleast close to it)

At Y0 and X0 what is your extruder offsets.

Attached is a diagram of my current bed layout and offsets
Blue is Glass
Dark grey blocks are bed clips
Red box is Probe area
Green is the are I can manually move the Primary Hotend before it wont let me move it more in software

Some details

#define EXTRUDER_OFFSET_X {0.0, 19.86} // (in mm) for each extruder, offset of the hotend on the X axis
#define EXTRUDER_OFFSET_Y {0.0, 0.195}

Thats odd... Have you tried to extend your probe area closer to the edge of the bed to see if it makes a difference?

If you want to test where the center is a quick 5mmx5mmx5mm cube will tell you where you are at real quick and wont take more than a couple min to print. You can adjust upload and heat the bed back up faster than the bed can cool down completely and you can use the graphics on the bed heated to measure your centerpoint... I dunno just throwing ideas for things that you can modify and see real world result crazy fast.

forgot to mention that in Simplify3d my bed size is set to 280x280

I havent played with it more yet. but i can do a test to see where it thinks my center is
