tried the search function and it keeps telling me something about a security error? Anyways the gear box for my lead screw is a little difficult to engage into reverse. Forward seems fine. As soon as it hits the detent it engages . Going from nuetral to reverse or forward to reverse I have to "jam" it to the left a little past the detent to get it to engage. If anyone has insight into this it would be greatly appreciated. No QCGB on this machine either
