    I've purchased a couple of kits from them. One of the kits is still in the box while the other is on my just-finished CNC Router.

    The CNC Router setup has what seems to be a dead-on-arrival power supply. Of the 3 power supplies that shipped, 2 work while the third makes a clicking sound.

    I've sent them an e-mail and await their response.

    Hi there, we check our sales history, we check you only bought 1 set of 3-axis Nema 34 stepper motor 1232 oz.in on Ocb 7th, 2014 on Ebay. We did not find that you buy couple of kits from our company. So please make a confirmation for it at your side.

    And it has been a year already since you receive it. We didnt know what happen in these past 1 year after you receive this parcel. I also replied to you in email, you can have a check.

    Regards

    Mary

    Hi Mary,
    I know this post has been a long time. I just want to ask you : changzhou-longs-motor is the same as changzhou-wantai-motor ? The product is almost the same, like a twin product.

    Why don't you put the wiring in here ? Thanks.

    Yes, I am using Longs motor with LinuxCNC. I like their DM542A stepper driver and use 25x microstepping with no problems. I am using a Mesa 7i76e ethernet board so don't use their breakout board but I have tested it and confirmed it works with LinuxCNC.

    Hi Rod,
    How difficult to wire linux cnc? How expensive ? Are they more powerful than mach3 or uccnc ?

    I think there is a reason why Tormach and CandCNC have migrated to LinuxCNC. Its better, its open source and its free!

    The wiring is probably no different. As you can have a lot more inputs with some hardware, you can wire in seperate limit switches and a home switch on each axis so there might be more wiring to do but you will have a better machine for it.. For a simple lathe or mill, there is a config program that should do 90% or more for you. I've edited the config files by hand for my plasma build.

    I have those same motors I just purchased from longs for two of my mills and I just heard back from longs after inquiring about the motor mounting and they responded that these motors are not designed to be used with ballscrews due to the high accuracy of ballscrews the steppers will not perform well. Have you actually ran these on your mill cutting anything yet?

    I'm only using their stepper drivers to drive my plasma cutter which is a low torque situation. I don't expect that their motors would be any better or worse than those I purchased from steppers on line. I do have a friend with a Seig SX3 CNC mill and a home made CNC lathe who uses the same drivers and he has no accuracy issues.

    I just bought this kit off of amazon, with no wiring diagram. I can figure out the wiring but can any one tell me which dip switch needs to be pushed, and the wiring diagram just in case. thank you
