This is incorrectly formatted. See M666. Format is M666 Xnnn Ynnn Znnn Annn Bnnn

That's strange. It has been that way since I made this file using the configuration tool 2 years ago.
But I will change it after reading.but the config-override.g has it correct:)

All working now. Camera axis tracks the effector's Z.
I have to re-print my camera carriage as the camera is too close to the effector when I run G32.Thanks for all your help.

I should be back home on Sunday and I will put together a short video show it in action.

Looking forward to seeing it!

@Quadcells I'd be interested to know what camera you are using.

I use WYZE, I have one on each of my printers. I also use them all over my house looking outside. Inexpensive and work great. Maybe a little big but for the price it's great.

Sorry it took so long to get you this video of the camera tracking the hotend:

@Quadcells that is absolutely amazing! Exactly what I was after. Could you put up you final config changes that made it work?
I've got a lot more work on my printer before I get to this mod and not a lot of free time but this has to happen!
Thanks

@veryevil Surething. I meant to post it but didn't get to it. I see if I can post the config.g tonight when I get back home.

Here are part of my config.g that relate to the 4th axis:

Config-override.g lines of code related to the 4th axis:

G91 ; relative positioning

;*** Slow homing has been configured. Change F180 to F1800 below when your configuration is working
G1 S1 X450 Y450 Z450 U450 F1400 ; move all towers to the high end stopping at the endstops (first pass)
G1 X-5 Y-5 Z-5 U-5 F1800 S2 ; go down a few mm

G1 S1 X10 Y10 Z10 U10 F360 ; move all towers up once more (second pass)
G1 Z-5 F6000 ; move down a few mm so that the nozzle can be centred
G90 ; absolute positioning
G1 X0 Y0 F6000 ; move X+Y to the centre
M584 P3 ; hide U4I believe that's it.
4th axis rod length is 20 times that of XYZ. I haven't tried changing it.
