Please help with configuring my Duet2 wifi for my upraded A8 (Metal frame, v6 hotend, BMG extruder). I have found learning and dealing with the documentation extraordinarily frustrating, as it seems to be designed to be surgically devoid of context, overly reliant on specific references where general ones would be far more helpful (and are often outdated or no longer valid) and near absence of helpful common examples. Nearly impossible to read. I have not had these problems with other 3d firmware. And I easily assembled my printer and figured out what I wanted/needed to change. I cannot decipher the interplay between z-stop and end stops in the documentation. I have the standard microswitches that the A8 came with. I had trouble getting the ABL working (3d Touch), despite wiring that I am confident I followed instructions.

I do not wish to sound ungrateful. The effort and expertise that went into designing this system is obvious. I only wish to suggest that documentation could be much more helpful to the user.

In the documentation and the firmware endstops are separate and distinct from probes!

The 3D touch seems to be a clone of the BLTouch (I've not used either...) so you are working on your z probe, not the Z endstop (which its common to not use unless you have a delta).

But try starting here if you haven't already

here is a good guide for the ender 3 which is close to the am8

@theruttmeister I did not know that it was common to not use endstops. I will give that some thought.

@Veti This seems promising, I will go through it. As it happens, I have an Ender 3 as well, which has been humming along perfectly.

I finally got around to setting up my dusty old Series 1 with a Duet and made the jump to using RRF3.x

All my previous work was with 2.x, this is also the first time I've actually had to dig into the wiki to figure out how to configure my Z probe.

You were really not exaggerating. The documentation is... not great.

You're too kind. It needs a pretty major rewrite with a separate page entry for each probe type I think.

For the BLTouch specifically the guide that veti linked has a step by step on getting it going in RRF2 and there is an upcoming guide for the mini5+ that address rrf3. Though the configurator should take care of the firmware commands to get it going.

Good documentation is the hardest thing to do...

The g-code page is remarkably good.

And the configurator is good so long as you are in the normal tracks, I was disappointed to discover that it doesn't cover SCARA machines.
