Gcode crazyness...

I am noting something very odd in repeater host. When I run my prints via PC my first layer comes out at the exact height I set my first layer to (in this case .2). However when I export my Gcode to and SD and try to run my prints via LCD controller my first layer starts out dragging the extruder on the bed, the controller says .2 but it is clearly not printing at that height.

 

keep your terminal open and watch the G29 response codes. See if they're different.

That is odd it seems the LCD sets the z-probe offset to 0.00 when I have it written in my g-code to set it at -.8 I don't know why it is doing that.

 

Are you using M565 or M92

 

custom g-code:

G28 ; home all axes
G1 Z5 F5000 ; lift nozzle
M109 S[temperature] ; set the temperature
M565 z-.8 ; set the probe offset
G29 n 3 ; probe bed

 

M92? do I just drop that in for z? M92 z-.8?

 

M565 defines the Z_probe offset, M92 doesn't that's why I asked.

Is this matter control?

 

No worries, I modded the "Z-offset" setting in repeteir host under extruder setting and got it working.
