Yes it is a bit hit and miss isn't it. I've noticed that on several of the Beaver documents |

Although when I set the machine to cut a thread 'in the air' it appeared to be cutting correctly, now I've been brave enough to cut metal (and actually mount a threading tip, and measure it's offsets, it is obvious that all is NOT well. It looks to me as though the spindle rotation is not synchronised to the Z travel. Presumably the controller should wait for a reference point in the rotation before firing off the Z movement whereas the two look to be asynchronous to me. I'd not be a bit surprised to eventually find that this is tied to the M19 spindle orientation problem that I'm having. Diagnostically it might just be a blessing in disguise, but then it might just be a pain in the neck :lol: This is supposed to be an M12 x 1.75 mm pitch thread ! |

Is it supposed to be a LH thread? |
