i managed to get my cnc to work with qtdragon_hd all four axes and vfd spindle. i added num_aio = 13 and the lines in qtdragon_postgui.hal but this error comes out: qtdragon_postgui.hal: 28: Pin 'qtdragon.x_width' does not exist. i looked at the procedure for silverdragon maybe for qtdragon_hd it is different?
