Centroid Community CNC Support Forum

Just completed the mechanical conversion for a 1.8kW DMM + DYN4 drive for a spindle motor. Having the same Centroid error code 455 Spindle Axis (5) encoder quadrature error. Did this ever get resolved? If so, how?

Just remember that when you drop the resistor you need both the 24VDC and 5VDC sources off the Meanwell PS (depicted in the drawing ShawnM attached). I ended up pulling the circuit board entirely from the DMM cables -- would've been easier to just start with fresh DB25s. Further DMM offered to refun...

After making mistakes, I'm looking at switching from the stock BLDC motor that came on the PM-30MV over to an AC Servo motor. Purpose is to maintain about the same form factor and weight, but to gain an encoder and torque. I'm specifically looking at the A15 frame DHT 1.3kW NEMA 42 DMM servo with a ...

Need a little more information: specifically wiring diagram, DYN2 or DYN4, if latter, if you're using the DMM to Acorn cable (CA-CUACRN-M4-1). Could be a wiring issue, but you could be dabbling with the header vs DB25 port issues many have encountered on this forum with DYN4 (me included). If you're...

Following-up. Received the new Acorn board and it works perfectly. Note: Once you order a new Acorn and it's been shipped from Centroid, you can't do the swap-out program. A little bureaucratic, but won't be a problem for me considering the grand plan to eventually do a CNC lathe as well (if I can e...

Not a bad deal at all at $199. Shot a note to support to see if it's too late to do the swap out program since I already purchased a replacement. If not, I save $100. If it is, I'll probably do the swap out anyway to have a test board until it goes on a second machine at some point. Appreciate the t...

Yep -- nothing. I ordered a new Acorn board. Best case, I have an extra Acorn for a lathe conversion I'll do sometime down the road. Worst case, my next victim is in the queue. Assume I burned up something in the analog output circuit -- possibly by trying to direct connect the output to the PM-30MV...

Re-wired to try this -- didn't work. Still no voltage off of the H8 header when commanding the spindle manually or through g-code.

@suntravel: The Acorn Wizard wouldn't allow a combination of Fwd, Rev and VFDEnable. SpindleBrakeRelease functions for relay purposes and doesn't require additional keystrokes to make it work, so I don't see that as a problem. Still no output voltage for spindle analog output (spindle speed control).

SpindleEnableOut isn't available as an output on my version of CNC12. I tried SpindleBrakeRelease as a surrogate. It activates properly as a relay output, but no change in overall outcome. The spindle analog output is outputting 3mV consistently regardless of commanded speed.
