    I guess you are waiting for me to try it.

    In the meantime, did you try to run your spindle with the POT control?

    Dear friend, I tried all the attempts, but unfortunately can not get it off if a way is one which is through the file that you work through the program ArtCAM and put all the information on the speed work with me, but not as fast, which I developed sense healthier, which I can not change the speed also and I researched a lot on the internet and did not get an answer to this problem

    Thank you in advance for your help me

    Regards

    Sorry, I am having a difficult time understanding your problem description.
    I am unfamiliar with the program ArtCAM.

    Suggestion #1 – Disconnect your spindle driver from tinyG. Move the Spindle driver jumper pin to the position to select the on-board POT.
    Connect your Power supply to the spindle driver. Turn on the power supply, adjust the POT 0n-board the driver from low (CCW) to high(CW)setting. Does the spindle respond at all?

    If not, it is not a tinyG problem, not sure how we can help you.

    ArtCAM – I took a quick look at their web site.
    Interesting stuff.
    I assume it just generates a GCode file, which you then load into tinyG ?

    Alhadar: One thing I have experienced in experimenting with my Spindle (similar, not identical to yours) and controller is that occasionally the spindle does not start spinning when I ramp up the speed POT – its needs a spin from me to get going. Not sure why. The top of my spindle is a cooling fan, I assume yous is as well; spin that.
    Goes without saying: be careful, it could ramp to high speed quickly.

    Just received from vendor the PDF for this Amazon spindle:

    LD52GF-400W Engraving Milling 400W CNC Spindle Motor Kits PWM Speed Controller with Mount Bracket for Engraving Milling

    Motor works. Can’t get the PWM to work.

    Interesting, I have what looks to be the same Controller, purchased perhaps 6 months ago. At the time, the PWM input spec was 5V to 12V, I believe.

    When you say “motor works fine”, do you mean motor directly connected to DC source, or motor connected to controller, and speed of motor controlled by controller POT?
    Start first with Motor – Controller connection in POT mode, to ensure basic connections and controller functionality. Then move the jumper to external mode and connect tinyG PWM signal.

    Here is a summary of a PWM test I ran back in January, note that I buffered my 3.3V PWM logic up to 5V.

    You can run the PWM from the command line (CoolTerm, ChiliPepper), the Gantry does not need to be in motion.

    What are your PWM Parameters (enter $p1 from Command Line)?

    Thanks! I’ll work with the notes in your link today.

    Yes, my motor test was a direct connect to 48v. My PWM board does not have a variable speed control or a socket to plug into. Helpful to know if the board LED should light when only 48v is connected.

    Oops, I c now. The internal pot is soldered on board…

    Set all of the suggested PWM values, verified that fuse is good, rewired and verified cable from TinyG PWM pin and gnd to PWM. Repositioned PWM board jumper for internal control and rotated on-board POT up down and in between.
    No go. Never bright LED on PWM. TinyG LED indicator for PWM signal bright with M3 command. I think PWM is defunct. Is there not a PWM compatible with TinyG that does not require the voltage mod?

    Hmmm , on my controller, the red LED is on whenever the Input (48V in my case) is on.
    Sounds like controller, I agree.
