Never mind, i figured it out. The reprap firmware configuration assistant was using M208 to set the minimum z height to 1mm. I changed it to 0mm and now when i run the calibration I'm getting 0.1mm as expected.
To be honest, the configuration assistant was more trouble than help. I'd almost recommend not suggesting it in your documentation.
Thanks @dc42 that got me further. Now I'm running into a problem where the G92 command at the end of the homing of the z axis isn't setting the z position properly.
If I execute the following gcode commands in the console this is what I get:
G92 Z0.1
M114
X:20.000 Y:20.000 Z:1.000 E0:0.0 E1:0.0 E2:0.0 E3:0.0 E4:0.0 E5:0.0 E6:0.0 E7:0.0 E8:0.0 Count 2000 2000 400 Machine 20.000 20.000 1.000
Because it thinks it's at 1mm after the homing the first layer is printed incorrectly. What do I have to do to correct the homing?
Here's my home z file:
G91 ; relative positioning
G1 Z10 F200 S2 ; raise head 10mm to ensure it's above switch trigger height
G90 ; back to absolute
G1 X20 Y20 S2 F2000 ; put the the head where you want it to be when you home z
G91 ; back to relative move
G1 Z-200 S1 F100 ; move z down until the switch triggers
G90 ; back to absolute mode
G92 Z0.1 ; tell the firmware that we are at z=0.1mm, the width of the paper used for homing (measured with calipers)
Can anybody give some advice on how to get somewhere with the levelling assistant that pops up whenever I go to print a file? I'm using a DuetWifi with the latest firmware and web software, controlled from my laptop. My printer's a DIY i3 clone cartesian. I don't have an automatic bed probe.
When I run the z home an assistant pops up and I can control the Z axis with the buttons and lower the head until it's gapped properly with a sheet of paper. I can even run the mesh compensation probe and probe for multiple points.
when I queue up a print the bed levelling assistant pops up but the controls don't work, I can't move the printer head. The head is raised very high off the bed while it's doing this so I can't gap it with a piece of paper.
My bed is square with a manual m3 screw at each corner.
I looked over the documentation and saw that bed.g has to have S4 at the end for 4 screws. I also have an M671 at the end of config.g listing the locations of each of the 4 levelling screws with a P0.5 at the end for 0.5 pitch for m3 screws.
I've attached the config files which should be pertinent.

I am wiring up an atx power supply to a duetwifi. When the ps has its von shorted it's outputting 12v perfectly but the 5v is outputting 5.2v. I'd like to let the duet control the von of the power supply but I feel the 5.2v output is unsafe. It's a name brand, 700w thermal take psu so I'm surprised it's not regulating the 5v properly. Could it be because the 5v sense wire from the PSU isn't connected to anything?
