I've been attempting to calibrate my Press for the past week. Soliprint crashes on startup when I've tried running it on an old Windows 7 PC, so I've been testing using RH. So I'm unable to run the SP Z-Offset calibration test. I've managed to set up all the configs in RP from this thread and others on the forum, but my print bed has a downward slope that is causing the extruder to have a few mm gap with the bed as it gets closer to front. The support structure fails to stick to the bed and it leads me to believe that the auto-leveling isn't really affecting the gcode. I've managed to print a few things when I move the object to the back of the bed where it is more level, but this isn't a fix.
Here's my start gcode for RP, per forum suggestions:
G28 ; home all axis
G1 Z-5.0 F5000 ; Move platform down 5mm
M565 Z-1
G29 ; Bed Check - Z-Offset
I also tried this start gcode:
G21; set mm units
G90; set abs. coords
G28 X0 Y0; home x and y
G29; probe bed
G92 E0; reset extrusion dist
Extrude temp is 250, bed temp is 90 (I've tried as high as 110 with no difference on adhesion). I'm using Aquanet hair spray on the bed and the ABS that came with the Press.
If I call M851, the returned Z-Offset is 4.10. Running G29 gets the following probe returns, but I don't get a Z-Offset value I can use:
00:28:38.040 : Bed x: 30.00 y: 170.00 z: 3.29

Appreciate any assistance! This has been driving me crazy.
