what is the min/max pulse width for the under voltage event to register ? i would like to test that .
.i think the default homing sequence should be better .
even my 6 years old 8bit board checks if the endstop is pressed before homing , and if it is , it tries to move the motor in the other direction to see if the endstop state changes . if not then something is wrong , and you hae an error.
You can do anything you like in the homing files. We'll look at making the homing files generated by configtool do as you suggest.
thanks for clarifying . so with those changes , from the software side of view 1 and 1.01 are the same .
Yes. There is an additional difference between 0.6 and 1.0, which is that the thermistor reference resistors are connected to VREFMON instead of VREF. RepRapFirmware detects the board version and handles that difference.
The motor being outside the enclosure is true for a convection oven (or other very hot air) fan. However, the back of an oven is still pretty hot. I would expect the windings and bearings on such fans might still be capable of fairly elevated temperatures. I used to wind coils out of HAPTZ wire (see, for example, https://wire-cable-tubing.wireandcable.com/viewitems/magnet-wire/heavy-armored-polythermaleze-round-magnet-wire ) which is good to 200C operation. A fan wound with that and with dry bearings might be available, and capable of running at 150C. Finding one is the trick, of course.
