Bridgeport Torq-Cut TC4G Retrofit

I will when I get back around the machine and power it back up. That will be later tonight or tomorrow, it is time for dinner with my son.

Current config attached.

The orient looks decent in the video. Did you get it resolved?

Currently I am orienting the spindle and once it is in position (within 0.5°) the orientation command is released. I would rather get the spindle to stay on, but the oscillation may cause issues.

Although the current way works well and is always within ~0.2° which is way lower than the play in the umbrella holders. Once the tool change cylinder is engaged the spindle is clamp anyway so everything always lines up.

I can orient in both high and low gear also, so no need to always change gears when orienting the spindle which is nice.

Down the road I will mess with orientation more. Hate for the project to be on hold over this as I tend to become fixated on things like this and will not progress further until resolved.

Quick though about your orient issue. Any chance you have slop or tension issues in the belt for the encoder?

Build up in the pulley teeth?

Bent encoder shaft?

Noose on the encoder cable?

Just got my spindle back from rebuild and was cleaning up the area and noticed how bad some of these items were. Kind of an odd setup for an encoder to run off a belt. I looked into switching to a magnetic ring encoder but was already over my budget on the rebuild.

Sorry about the late reply. Progress on the mill has came to a halt while I await my replacement thrust bearings. To answer your questions:

* Belt tension is good
* Pulley teeth have been cleaned and new belts installed
* Encoder shaft is true
* Encoder cable is good
* Tried secondary encoder as well with same results

Belts on spindle encoders is pretty common and have worked well for years on many different OEM machines.

Glad you got the rebuilt spindle back. I am still debating removing my transmission, just not sure yet.

I will update later this month as when the bearings arrive. Again sorry for the late reply and lack of updates.
