You can use this for the case you are working on if the customer is not of need of a controller to control the line speed or extruder speed.
If he needs a controller, he would need a USYS 20 instead of the WIREMASTER.
I did an offer for them USYS 20 –ODAC 64XY in March. (Q03-14-0561)
So you can use this one in case a controller is required.
