Coordinates offsets
I've been working around this, but I must be misunderstanding something basic about the environment. My printer homes off the bed to the left, so I have the X-axis and Y-axis printer setting home values set to -45 and -7 respectively in the printer EEPROM (and then these values are imported into repetier home/server). These values make 0,0 the lower left of the physical bed. However, when I printed objects via repetier server, they would always be offset considerably from the center of the bed, despite appearing centered during previews. I solved this by use of:
G92 X28 Y4
before a print while in home position. This pretty much centers the actual physical print on the bed. However, when viewing the print progress in repetier home (connected to repetier server) the 3D image is typically shown offset hanging off of the bed partially or completely.
What am I missing here? Thanks!

The moves for pick up of the hotends are made by the slicer software.
For me the the +- z Move of the z-offset on Tool Change is missing.
Another question: are there different moves on G90 and G92?
Here the tested g-code
g90
g28
g1 z0.2
g1 x10 y10
t0
g4 s3
g1 x250 f1000
g1 x180 y10.1
t1
g4 s2
g1 x180 y200 f2000
g1 x180 y100
t0
g4 s1
g1 x50 y100 f1000
g1 x80 y100
The x moves are with T0 (Ext1) and the y moves with T1 (Ext2).
it is the switch you tested. And what is the result?
The first x moves are on level z0.2, the y moves are also on level2,
after the toolchange the printbed goes to z10, the next x move g1 x50 y100 starts with Z10 and ends at Z0.2 and the last move is on level z0.2. (The LCD shows after all x=80.00, y=100.00, z=10.00 but the Hotend is in real on Z0.2!) The correct Z Level with offset must be z10.2 and not z10.00!
No I am not using the dev version.
thx
