Hey Chris was hoping you could tell me how you went about wiring the mi8 interface board to the acorn. I’m looking at your board wiring and it appears you wired it different from the schematic from Renishaw. I see you have common jumped and running out towards the acorn. Is this for the probe detect ...

Lol thanks I’ll try that!

There’s a couple reasons I thought a large servo would be a good fit. 1. Servos have a very broad torque curve allowing you to run the spindle very low rpms with high torque. 2. The ability to orient the spindle for probes etc... 3. Holding torque at 0 rpm, Eliminating the need for mechanical ...

My mill(hurco hawk 5) is in dire need of a new spindle motor. I’ve seen some guys on YouTube building mills using larger (3.7kw and up) servos as motors for the spindles on their machines. Is this possible to do using my centroid acorn board? If so would the drive for the servo be used as the 4th ...

I finally got my db25 breakout board in the mail so I spent Sunday getting it wired up and tested. I now have my green and blue step and dir wires running to the db25 on the acorn. I could not get the motors to turn and after playing around with the settings in the wizard I changed my settings from ...

Marty I tried using the screw terminals along with connecting 5v DC to the power supply and it didn't fix the issue. Still missing steps. Hoping using the step and dir from the DB25 resolves the issue! Will I need to change anything in the wizard when using the db25 on the acorn? Also will all other ...

Finally got around to working on the machine again, it’s boating season😁

Got the control/computer mounted. Ended up picking up a swivel tv mount and modifying the mount and original computer stand.

Thank you so much! This is exactly what I needed!

I got my spindle brake wired up using an air solenoid valve and was hoping someone could advise me on how to set the time delay between when the vfc shuts the spindle off and when the break engages. I am using an acorn board running the latest version of cnc 12. I found parameter 990 and from what I ...

The cable has the braided shield and a drain wire. Bought it from automation direct. 4 conductor 14 gauge. I think the problem is the cable runs down the wire way next to the acorn drive. I pulled the vfd and I’m going to mount it either on the wal behind the machine or on the back side of the ...
