Tested 3.3RC2 and the touch probe is still working

Just wanted to share my final version of my touch probe macro

; Touch probe.g

@peirof Have a look at the Rat Rig V-Core 3
Default: https://www.ratrig.com/3d-printing-cnc/3d-printer-kits/v-core3default.html
Configurable: https://www.ratrig.com/3d-printing-cnc/3d-printer-kits/v-core3configurable.html

@charles-fraser The power supply is 350W as stated in the name LRS-Wattage-Voltage. You can also calculate the wattage by multiplying the output voltage (24V) by the amperage (14.6A). It should be more than adequate to drive the Duet 3 MB6HC mainboard and a (number of) expansion board(s).

@dbruce-ae05
No need for splitting and recombining (Duet3 6HC firmware 3.2), just assign 2 motors to Y and check 2 endstops

@o_lampe I guess you've missed the but in my answer, a USB stick will be used.

@fcwilt
Thanks for pointing me in the right direction. Problem solved !!!
I do wonder how it ever could have worked before...

@sindarius Is it possible to have the probe status back please ?

@cthulhulabs Thanks, wouldn't have caught that !

@theKM Can't you just jog it close to home before starting a slowed down homing procedure ?

@o_lampe I guess you've missed the but in my answer, a USB stick will be used.

Thanks all,

@jay_s_uk The SD card was a Kingston 64GB, but will go with Raspberry Pi in SBC mode.
@o_lampe The eMMC looks interesting, but I will sacrifice a USB port of the Raspberry Pi.
@dc42 Going with the SBC mode will solve this one as well.

Should I wait for the official release of 3.4.2 or would RC3+ be reliable enough ?

Thanks again,
Yveske

After yet another corrupt memorycard, I was wondering if it would be possible to boot the Duet 3 6HC from the USB port.

@TheDragonLord Would it be an option to add a rail in front of the motors ?

@fcwilt A cheaper, mechanical way of doing things

@phaedrux I feel an opportunity coming up for watercooling modders and RGB enthousiasts

@sindarius Thanks a lot !!!
