Arduino DUE SAM3X8E Ramps1.6 spindle PWM output

[MrSpindle]

Hi everybody,
total newby here who wants to switch from grbl on an Arduino Mega with ramps 1.4 to Arduino Due grblHAL and ramps1.6.
I was able to compile the grblHAL in Arduino IDE with compatibility mode to work with UGS, that worked well- I can also switch on the spindle wit M3 Sxxx commands and switch it off with M5. But I cannot find the PWM signal, on the Arduino Due. Spindle Enable Pin is on Digital Pin 4 (works if I enter M3 S200 ). The Ramps is not powered up so the Due is only connected to USB.
Pin 11, 12 13 do not work
Any ideas, any help would be musch appreciated - thanks!

the Readme from grblHAL is referring to this build:

I can enter the speed but do not get any status on the speed- it is working with the old Mega 5x setup though

Ok I changed the switched the digital output pins for the spindle direction and pwm in the ramps_1.6_map.h and now the pwm output works on pin 5. UGS still does not show me an spindle speed.
ramps_1.6_map.h Lines 113 to 130

#ifndef MODBUS_ENABLE

// Define spindle enable and spindle direction output pins.
#define SPINDLE_ENABLE_PORT PIOC
#define SPINDLE_ENABLE_PIN 26 // Due Digital Pin 4

#endif

ok we solved the Z axis issue- there is a typo in ramps_1.6_map.h in line 58
#define Z_DIRECTION_BIT (1<<Z_STEP_PIN)
should be
#define Z_DIRECTION_BIT (1<<Z_DIRECTION_PIN)

sorry I don't know where to report, we are not so familiar with git here...

I have found it too, no need to report. There are copy/paste errors in other map files too.

[MrSpindle]

ok perfect, we are using the test branch right now. apparently the $G soft reset ist not working as well. I have to reset the Due to reset the grbl.
Using UGS with compatibility mode still.

[terjeio]

apparently the $G soft reset ist not working

$G is for outputting a parser state report, use <CTRL>+<X> or <CTRL>+<C> for soft reset.

[MrSpindle]

ok, I may have mixed stuff up..
I had to set $10=0 in order to zero all axis- I suspect that grbl was set to zero but UGS didn't show that.
Thanks again for your support and work on grbl!!!
