My OneFinity Elite is equipped with a spindle motor that is earth grounded. With my original Journeyman I could probe without the magnet because the spindle was grounded and the probing circuit was satisfied with the earth ground of the spindle.
Is it possible to do some magic and eliminate the magnet for probing on the Masso equipped Elite? BTW, I have tried probing without the magnet (by mistake ) and discovered it doesnât work!
I suspect thatâs a solution youâre considering though. You could also remove the magnet and wire that lead to the frame. Assuming weâre talking about the same spindle, and not a new one with ceramic bearings, that should work.
Thanks Adam, my spindle is a Mechatron and it doesnât have ceramic bearings. So, for example, the magnet attached to a frame bolt of the OneFinity works. That does help eliminate the risk of not attaching the magnet everytime. The better solution might be to cut the magnet off and put a more secure frame connection on that lead.
I am wondering about bonding the OF frame with a G3 ground. This was suggested on the Masso forum but there seems to be some concern about mixing the grounding/bonding between the spindle and the G3 controller.
I have not looked into the 3D probe too much. I have seen it and was reminded of a Heimer 3D-Taster.
[quote=âAiph5u, post:22, topic:12331â] Ground the machine in accordance with the regulations!
The machine in which the motor spindle is installed must be grounded separately for each moving machine component. Even if, for example, the moving axes of a milling machine are electrically conductively connected to each other via ball screws and linear bearings, this electrical connection is insufficient for the protective earth connection and must be supplemented by a separate earth connection for each axis in accordance with VDE regulations. A protective conductor test must be carried out individually before commissioning.
