Hit Home All and got all three reporting triggered.
Still having issues though. Kinda stumped right now.

Everything seems fine until I slice, it seems. The object will be at Z0 until after it has been sliced, then a raft auto creates itself. Once the raft is done printing, the first layer drags like an uncalibrated printer.
EDIT: I should add that I updated RH before rewiring the Sanguino board. After trying to reinstall RH 0.95F, RH crashes religiously, so the modern 1.0.4 (?) is all I can get to open.
Is this immediately after Homing All? If so, the Z should read "Triggered" as well...

Couldn't see that from my smartphone but... Yep it should also read triggered.

After fiddling with Slic3r, I found that the raft was set to 1. Once Set to zero, my current print is running as usual.
The odd thing was that once the raft was set to 1, the base layer was higher than expected....almost like it skipped a layer.
This is something I will have to address in the future for more prominent designs, but "if it ain't broke"....

Thanks again for your time IronMan.

Will do tonight.

Try the M119 command...

Sorry I haven't gotten back on this thread...had some good friends in from out of town.
After reviewing some of the gcode I really cannot find any reason for this, and it is appearing on all prints.
My current theory is the Z endstop plug being flipped, but it wouldn't matter which wire goes to which pin, right? Since the pins just send on/off messages? Could be wrong on this though.

AZERATE,

How did you make out with this?

Re: Manual Control vs Axis Homing

Here's what my g-code header looks like:

G21 ; set units to millimeters
M107
M104 S198 ; set temperature
G21
G91
G28 ; home all axes'
G92 E0
M109 S198 ; wait for temperature to be reached
G90 ; use absolute coordinates
G92 E0
M82 ; use absolute distances for extrusion

I don't know why yours would have the platform move down 5mm with the G1 Z5 command; then it moves back to G1 Z.45, which is almost a half millimeter away from the platform...you could try editing those out before running the print, but I would hate to crash your nozzle for some reason!

Some others who are more expert please weigh in here!

Yeah. Z offest is at zero. Kinda stumped at the moment.

Re: Manual Control vs Axis Homing

I think the G92 E0 has something to do with setting the extruder to zero...

Have you check in slic3r under the Printer Settings tab? I think that is where the Z offset setting is.

One more question for the panel:
Ran a test print a few times and there is now a Z offset when beginning the print...was never there before.

G21; set mm units
G28 ;home all axis
M190 S97 ; set and wait for bed temp to be reached
M104 S245 ; set extruder temp and start heating
G90; set absolute coordinates
G1 Z5 F300 ;move platform down 5mm
G1 X10 Y10 F3000 ;move to front left corner
M109 S245; wait for extruder temp to be reached
G1 Z0.45 F200 ;move platform close to nozzle
G92 E0; reset extrusion distance
G90 ; use absolute coordinates
G92 E0
M82 ; use absolute distances for extrusion

This is the beginning gcode for the part. I am no genius with the coding, but is my theory correct that to G92 E0 command is the culprit? It is not found in my custom gcode, and it just began showing up.

After getting a totally awesome night of sleep on it, I checked the plugs again. X was in Y and Y in X.
So IronMan was correct.

Thanks for your help!
