Hello Marry, if you pop up the debugging console in the controller app (use ctrl+c on Windows), you'll probably see a message coming from the machine saying something like "this line is not on the page, skipping it" when you do your square drawing. (Another quick way to do a square is to select a rectangular area using 'select area' and then click 'outline area'. I use that to test how big a drawing will be on the page.)

What this problem usually means is that your machine has not been sized correctly, or there is a mix-up between the size the machine thinks it is, and the size specified in the controller app.

If you press "download machine spec" then you will find out what size the machine thinks it is - it will be loaded into the controller app.

Are you happy with how to set the home position, and things like that?

The reason that 'move to point' works, and 'move direct' doesn't work, it because move to point is dumb - it just blindly does what it is told, even if that would result in moving the pen off the surface, or defying gravity somehow.

'Move direct' actually tries to figure out where on the surface the pen is, and where it is going to go, and it'll just ignore you if you try to do something impossible. One common issue is that it needs both ends of the line to be on the surface - so if the machine has been given a weird (impossible) home point, then it can never get started, because the starting point of the first line will always be somewhere off the surface.

Good luck!
