Extrusion never begins (ormerod 2)

Hi,

I'm new to the 3D printing world and I have just assembled an Ormerod 2. I have run all checks (proximity sensor, nozzle heats up, fans work OK, xyz movement, temperature reports OK, bed heats up, all motors work fine) but the problem is this:

When I try to print snowman for example, the printer does its calibration on the 4 corners where the white papers are and then moves to a position that looks like (0,0,0). But it never begins to print!

- When I do this via the web interface I always get the JSON error at this point
- When I do this via the USB interface software I get an error about an external tool not defined. But if I send "T0" before printing, when printing begins it disables T0 and I get the same.

I am using the latest firmware, currently 1.09, but have also tried 1.09dc42 with the same results. Windows 7 64-bit system.

Any suggestions would really help at this point.

Thanks

Try posting this on the Ormerod forum.

OK thank you

*Update: the problem was that I updated the uController firmware without updating my SD card :-)
