Extruder Offsets

Where is this set? Firmware or Simplify?

I have used both. But prefer to keep my users out of the firmware.


Thanks

What firmware are you using? Some firmwares allow you to update these offsets with a simple G of M-code. But most of the time, these options are configured by the manufacturers with the default values hard-coded into the firmware. That way us users don't need to mess with it at all :D

I am using MARLIN. I was the one that had the following added to MARLIN about a year ago now.

// Offset of the extruders (uncomment if using more than one and relying on firmware to position when changing).
// The offset has to be X=0, Y=0 for the extruder 0 hotend (default extruder).
// For the other hotends it is their distance from the extruder 0 hotend.
// #define EXTRUDER_OFFSET_X {0.0, 20.00} // (in mm) for each extruder, offset of the hotend on the X axis
// #define EXTRUDER_OFFSET_Y {0.0, 31.28} // (in mm) for each extruder, offset of the hotend on the Y axis


This is when I used Replicator G and Skeinforge back in the day.. When I moved to Slic3r and Repetier, Slic3r had the offsets built in.

I will go back to using this if Simplify3D does not support it in their software.

Thanks

I ended up fixing the issue by not using the firmware. For some reason the commands were being ignored.

So what I have done is the following

I added this to my gcode.start file.

M218 T1 X0.0 Y31.28

and added this to the (tools) (firmware) ( General) (Tool Change) T$ F5000

This seems to work just fine.

Hello from Italy,
I just finished building my new printer, but I had the bright idea to put two extruders. I use, Marlin and latest version of S3D but I can not get an offsetting the extruder, I have tried both in Firmaware and S3D. But no I can not change the value of T1 than T0, I have a value of 60 mm on the Y axis Advice? I use S3D with iMac.
I tried as it says Jeff but nothing .... :?:
help, I am on the high seas
