    Help: UNKNOWN COMMAND G29 (and others) trying to use bltouch

    Hi,I've been using an Ender 3 for 1 year and I'm quite happy with it.Recently I replaced the stock mb with a SKR MINI E3 V1.2 and the printer became silent.Then I replaced the stock TFT with a Bigtreetech TFT35-E3 V3.0 touchscreen: very usefull.Then I installed a BLTOUCH clone but there's something not matching...When I power on, the bltouch lights up and the brobe goes up and down twice.When I go to levelling menu (touschscreen) and press autolevel I get UNKNOWN COMMAND G29.Other levelling functions give me other errors like UNKNOWN COMMAND M280 and so on.It seems many commands are not recognized.What's the problem here?

    These are the components:

    I'm not an expert, but to my understanding SKR MINI E3 V1.2 does not recognize a set of commands sent by TFT35.
    It's a firmware issue or what else?

    How can I get the whole thing working? Thanks in advance.Gico

    Found a firmware w/bltouch support for Ender 3.
    Set the offsets. Recompiled. Now it works!
