Lagunmatic 3516-SX Retrofit

No real obstacle other than waiting for a few parts to arrive! I don't anticipate any huge issues getting to that point

my spindle drive had an orient input and orient complete output on it, which was nice. not sure if yours does. If it does, it should be fairly simple. I'm not sure if our machines are identical, your pinout might be a bit different. But as long as you get your inputs and outputs right, you are probably better off just using my config files, unless you want to learn the hard way.

I had to replace the original spindle drive, so I lost the Orient signals and others. I'm sure this can be overcome but not certain how yet.

I plan on redoing the config files and copying over what makes sense. Having your files to look at has helped IMMENSELY! But I want to learn as much as I can to ensure I can customize/expand the machine in the future.

did you see any feedback from the spindle motor to the drive? I haven't really looked, but there should be a sensor or something of the sort on the spindle. I'm fairly certain there is not an encoder though. You can make a very simple encoder with a home made tone ring and some cheap emitter/collector pass through sensors... i did it on my old mill so i could do rigid tapping. Worked really well and it was cheap... probably 20 bucks in parts.

Yeah I do have some options here. My spindle motor has encoder feedback and I have an encoder feedback card for the Teco A510 spindle drive. There is also a 2000ppr encoder connected to the spindle cartridge (the spindle motor is connected to the cartridge at a 4:5 ratio).

I think my best option is to run the motor encoder to the spindle drive and close that loop in the drive, running in V/F+PG mode. Then run the cartridge encoder to the 7i77 and use it for rigid tapping, maybe RPM display in LinuxCNC, etc.

This method wouldn't require me to run any extra wiring between the two control cabinets, so that's a plus.

Finished up the CAD design of the new pc panel. I 3D printed brackets for the DB15, DB25, and DB37 breakout boards as well as a piece to hold the computer components.

Just waiting for the wire raceway to show up, should have everything wired and installed by Friday.
