I have a CTC prusa i3 pro B, It has a GT2560 rev A board. I've downloaded the latest version of marlin (1.9) and done the necessary changes to enable the sensor.
Gcode to deploy and retract the pin works, as does the self test, however, when I attempt to home the Z axis, without fail every time, the nozzle crashes into the bed and the probe doesn't deploy at any point
When I send M119 when the pin is triggered, I'm intermittently getting open/triggered signals. I'll send the code 10 or so times and get open, then randomly get a triggered signal, even though it should be triggered all the time..
If anyone has any ideas as to what may be the problem id be really grateful for the help, i've been at this for 3 days and no results so far.
I'm a mechanical old guy that is trying to get a ctc i3 pro printer running and have a couple of issues that I can't solve.
I believe I have a Anet board with the following info. on the chip.
Issues are as follows:
1) I changed the original threaded screws to a 2 start, 2mm pitch, 4mm lead screw and can't figure out where I'm suppose to change the steps to mm this change requires.
2) I can't change the hot end nozzle temp. A change is Cura does not change the temp. on the display. I does heat up to 180 F but I cannot change it.
Any help would be really great
