Need replacement X axis stepper motor for Atomstack X40 Max

I am looking for a replacement X axis stepper motor for a Atomstack X40 Max laser. I contacted Atomstack customer service and asked if they sell replacement parts. The answer I received was ; “Go back to the authorized seller where you purchased it for assistance.” I bought the unit from a private party knowing there was a problem. I determined that all it needed was a stepper motor. There is a model # on the motor ( C54-0156-0AA1) more numbers (42DND005B-27D22) ( KH 2023 08 07 )
I am sure these numbers are specfic to the motor. Any advice would appreciated.

None of those numbers bring up the right motor type.

Measure across the face, that will get you the NEMA size, likely a Nema17 or Nema24. then count the pins on the connector, that will give you the wiring design.

Or you can use Google to help. I found this in about a minute using “stepper motor for K40 laser”:

I checked my X40 stepper against a data sheet i have and the stepper is a Nema 17 with a six pin connector. It should be 42.3 mm wide. It wont let me upload a PDF here but if you send me your email address i can send it to you.

Here’s the pdf file. just change the extension back to pdf

It will if you add .TXT to the end of the filename. If you email it to me, nobody else can review it.

I finally was able to get back to doing the repair on my Atomstack laser. Atomstack sent me a model # of a stepper that they recommended. I installed the motor but cannot control the Y axis. I connected the Roto attachment to the Y acis circuit and it functions normally. So with that being said, I believe the new replacement stepper could be faulty. I also connected the X axis lead to the Y axis motor and still no X axis control. Could it be possible that the new motor is either faulty or is the incorrect motor?

Another option is that the connector is wired differently.

Does this mean the motor did not move at all?
