Both Steve and Rob are on the right track in troubleshooting the error. We've received a fair number of machines that have had similar issues. The motors are independent and both go back to the MOT card of which we have repaired. Let us know if we

I generally do not design an array larger than 10" x 12". Other than just thermal mass, the one issue to watch with extra length is if the array is so large that it spans multiple heat zones at the same time. We have panels that are up to 48" l
