I have been compiling a file at various scales. At 1:1250 it compiles but at 1:2500 it goes into a loop and doesn’t finish The only difference other than the scale is a change in font size, to try and remove the small fonts [Warning: text scaled down to fit the path in scrap stpaulsps6@stpauls.summerti me.agenallwedd] [1259] [1260] [1261] [1262] [1263] !

Then it starts repeating the lines again. It there another way to remove the XS and S fonts ? # Change text size and remove xs and s fonts code metapost fonts_setup(0.5,0.5,30,40,50) endcode John
