Bonjour Deux Vis,
Thanks for your reply.
We are using the Techzone monotronics -with their firmware as well, which is supposedly the most up-to-date.
I just figured it out!! You have to have the reverse button in the "on" position and then you have to click on "Run extruder" - I thought reverse would just reverse on its own... silly me
I seem to be answering my questions these days! At least if someone else has the same problem they will find this message, I hope.
