OK - I just ran out to the garage and put the Multi-Meter on the Driver Alarm Output terminals - they appear to be NO. Is it possible to use three different Acorn inputs to interface with three different driver alarm output signals? If so, that's a really easy way to fix this. Or, can I wire the thr...

I was literally just watching that video and was about to drop the link in this thread! Thank you for making it. I'm not sure if the drive alarm output is NC or NO. If they are NC, I guess I can wire them up in series and use one Acorn input, right? If, for some reason, they are NO I do have the pro...

Hi Guys - many of us have used these HBS860H Closed Loop Hybrid Stepper drives on our conversion projects. Does anybody know the correct way to connect the PEND or ALM driver outputs to the Acorn inputs? It looks like it's easy to connect a single drive to a single input but how do you connect multi...

Hi Guys - I'd like to bring up a point about Fusion360. First, it's awesome. Never before has such powerful CAD/CAM software been available at this price point and they continue to make it better every day. As far as CAM goes, the milling portion of Fusion360 is great - I use it extensively. Unfortu...

I just stopped by the Missouri Grizzly warehouse yesterday and they have been out of the G0678 Mill for a bit. They have 5 on back order already and say they have 13 on order, expected delivery about the 2nd week of December. So maybe I will go ahead and get one so I can start on this conversion. I...

Hi Guys - here are two videos that may be useful to some degree: https://youtu.be/bNBSLE0KbcU https://youtu.be/DRb0WAIequ0 Naturally, I'll be making CENTROID versions of the Fusion360 post processors as soon as I have time. One additional comment: Milling in Fusion360 is really good. Turning (IMO) s...

Here is the first video:

Seems to be working OK so far. We'll see how well it holds up.

In a perfect world, I'd like to be able to use the Acorn relays to turn the spindle off/on and control the direction. I would be extremely appreciative if you could make a video explaining what to buy and how to hook it up. That would be awesome!

A pulley and belt are a better choice. I wanted to start with the gear as that can be a simple bolt on to the machine that doesn't require any disassembly. I'll be testing it out this evening. I'll let you know how it goes.

The encoder gear and the bracket are 3D printed ABS of my own design. The gear may work but I'm concerned about the vibrations. I may be moving to a pulley configuration if I see a problem.
