Viewed the "Grizz" photo album today. Atomarc is amazing, such skill. I wish I had some of those skills.

Aerospace quality workmanship.

Look at the KB-SI-5 which I believe is an isolator that attaches on top of a KB DC motor controller

I have this; Franco on the Centroid forum has a PM25

The guide (Page2, number 2) says that NC probes require a "Probe detect" input.

Have you wired a Probe Detection circuit?
Like the "Poor Man's" switch on page 7?

I believe you got it working by adding the 24v jumper shown in the print, between H9 and H1 (or H4)...

There are some recommendations to connect DC voltage wire shields to DC COMMON

But most recommendations are to use EARTH.

Most likely any interference is introduced by AC fields, and even a DC...

Shields should go to EARTH, not any DB25 GND pins.

There should be one earth ground point, so route the shields to that point.

Disregard, I found one locally for $1200

Located in Miami, would prefer something in South Florida.

On 24v these motor were bad in Mach3, it wasn't until I update to 48v that the motor operated as expected. If they miss steps when you slow the accel, then that is a problem. Is there any binding the...

To me lost steps, mean you are try to drive too fast (for the voltage) and the motor is stalling rather then move. I would switch to a 48v power supply for the motors for sure...

I like the Pokey...

I removed all these electronics and went with a Pokeys57cnc controller on my HY6040.

If you need spare boards, please let me know.

I was able to determine "Motor Tuning" settings by trial and...

No

From my notes
If wrong rotation direction then mirror them so abcd becomes dcba

By the way, what amp circuit will you be plugging this 2.2k spindle into? At 110v, it can draw close to 20 amps, so a 15 amp circuit will be too small...

Vso to vi, and then gnd to dcm or acm

You should be able to measure 0 to 10 volts between VSO and GND, depending on what speed you are asking the offline controller to set

If the optional POT...

Basics;

Does a 10k pot between VR, VI, and ACM control the spindle speed?

Does a switch wired between FOR and DCM, start the spindle?

PD001 and PD002, need to be set to "1" external...

When it is too good to be true, then ...

Reviews look good, pictures are not all the same machine.

New Home for Super-PID

Shawn

Can you post your motor tuning numbers? and the part number of the upgraded steppers?

Thanks

Hey Shawn, good to hear from you.

My rebuild is currently stalled. I have a few projects which got ahead of the rebuild.

There is a lot of extra reinforcement added to my machine already...

page 25

check voltage at "POT" or "Pin 8 VFD Output", does it increase? Does the voltage drop back to a 5000 rpm setting ??

Found a 48 VDC power supply which fits inside the column of the HY-6040.
Part number EYE-400W-48V-8

WOW, these stepper motors love the increased voltage.
These 57BYGH276-3004A steppers are...

Hey Shawn can you share the part number of this power supply.

Thanks

Benchtop metal cutting mill, like a Taig mill 105lbs for CNC version.

Look here; https://www.cnczone.com/forums/benchtop-machines/

Cnc3018 does not appear to be for aluminum.

Sell what you have and upgrade to a heavy machine, my advice.

Driver is not normally repairable, but I would at least open and inspect the circuit board carefully for "Open, broken" circuit components.

The DQ542MA are available on ebay

Swap inoperative Y driver with the X axis driver and verify that power is correct at the Y driver.
Either defective power or the driver.

Still proceeding with my HY-6040 rebuild. Motor tuning the Pokeys57cnc to the M542T drivers. It is coming together, will post pictures soon.
