I picked up my TinyG this morning and got it set up with Chilipeppr with no trouble.
To test my machine I’m using a sharpie to plot some text. The problem is Chilipepr says it will be about 61.09mm wide but it plots it so it is about 241mm. About 4x scale.
I’m not sure if this is a Chilipeppr or TinyG problem. Perhaps its a setting in the TinyG I messed up.
Just for the record, I’ll document your find that $_tr was set for 2mm but in fact they were 8 mm lead screws.
So setting $_tr=8mm corrected the behavior.
