You are correct. I set up the printer in 2019 and it was so reliable at hitting print then walking away that I never checked for an updated firmware! I'll go see the process of updating, I assume now it's a 3.xx that there is significant revisions. Given I am starting a fresh with the coding I'll just back up my current settings to refer to if things go wrong.

M557 P10 sounds an excellent idea, saves me doing the maths and will maximise the probing area.

So basically maximise the space the probe can reach, use Px and I should have the most accurate bed levelling possible?

Thanks again for the fast and helpful reply!

There are a few things that change when configuring v3 firmware compared to v2.

For example, in v2 the pin names for things are specific like estop1.

In v3 the hardware has generic pin names like io3.in.

You use the command M950 to specify what pin you want to use by it's generic name and what you want to use it for.

For example M950 H1 C"out1" Q100 T1 creates heater 1 (the H1 parameter) using pin out1 (the C parameter). The Q parameter specifies the PWM frequency and the T1 parameter specifies which temperature sensor to monitor.

A "how to" guide for configuring with v3

Aside from the actual changes you need to make to your configuration you need to upgrade to v3.3 (the most recent in two or three steps.

For example, I was starting from v2.05.1.

But for technical reasons you have to go from 2.05.1 to 3.0 and then from **3.**0 to 3.3

Thanks Frederick. I've just been reading those articles, prepping for the update whilst a print finished. I think what I might do is update the firmware then re-install the settings using the reprap configurator as it's easier for slightly clueless folk like me. From there I can jump into config.g and the others I've edited manually to adjust things as I have done for the current settings.
