    We don't setup touchscreens in marlin. This is because they communicate over a serial connection. You know, like USB. We adjust the device to what the controller is doing. That is match the baud rate. And most tfts do not like 250000 and you need to set the mainboard to 115200 and then the tft set to that and enjoy the magic. They get 5v pwr, gnd, then get latched to rx and tx pins but not from the usb controller. And so these are more akin to setting up a usb device. The settings for the screens in marlin are for things that occupy the exp1 and 2 sockets. You know the ribbons of old. You can not connect rx to rx and tx to tx. these are recieve and transmit pins and need to cross each other. the mainboards recieve should be wired to the screens transmit. And vice versa. And a lot of these boards are limited in how many serial devices they will support at one time. THis is my problem with the MMU. It too connects to a serial connection and so I can not run the mmu with the touchscreen. And you will find poor or no actual functionality of your touchscreen when you are connected to usb because that serial connection gets prioritized. However, there are mainboards with better support for more serial devices. These include but are not limited to the SKR PRO, The BTT002, or the 11 axis GTR 1.0. Those are just the supporting options from one manufacturer.

    So just in case that's slipped by you: AAAAARRRRGGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHH !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    That's better ;-)

    I ran through the repetier config process, connect the board, load the repetier.ino file and - obviously - get an error.

    Apparently ide doesn't think that something in the sd card setup is right.
    I can't see anything wrong, and - obviously - it won't tell me exactly what it thinks is wrong, so it won't compile or upload the bloody firmware.
    sheesh.
    At that point I swore copiously and gave up for the night.

    I'm currently contemplating just giving up entirely and putting the thing back together with the original board and screen.
    I have now modified the z-axis endstop so that it's a simple bolt screwing through a nylon locking nut, which was the only physical issue I had with the machine.
    Once you screwed the bed nuts down so that the springs are really tight - it was almost impossible to adjust the end stop bolt as it used three nuts that you couldn't really get at.

    Now it's just a simple hexhead bolt that goes up and down without any hassle and won't move by itself.

    I have noticed with arduino ide if I open arduino by double clicking on the file it is like certain libraries or things do not get loaded with it and it wont compile. However, if i load arduino ide by itself and then load the file within that I always find the joy. But on this side of 2.0 I use atom and dont use arduino anymore. Have you thought about trying to setup Marlin 2.0.5.3 ?

    well this is shelved for the moment - as it's 'spot' is now occupied by the sapphire pro.

    Until I fix a new shelf up for the ctc, it can sit ontop of the shelves and observe the working printers and learn :-)

    Given the board I bought is 32 bit - I'll probably try smoothieware first. Just soo much easier to both setup and update.
