I'm new to the forum but have searched and found no similar topics
I run a YooCNC 3040 engraver with a registered copy of Mach 3 Version R3.043.066. The controller has the "NT65-3X" control board and a "PW3024" power supply/spindle control board.
It's been running good for a year to cut ABS and etch PCBs. But I have always had to control the spindle manually. I really want to have GCode spindle control.
I use a simple DC engraver motor (no VHD?). My settings are as follows:
Output Signals Engine Configuration... Ports & Pins
Motor Outputs
Spindle
Enabled - Checked
Step Pin # - ? Does this need to be set? To what?
Dir Pin # - ? Does this need to be set? To what?
Step Port # - ? Does this need to be set? To what?
Step Port # - ? Does this need to be set? To what?
Output Signals
Output #1
Enabled- checked
Port #- 1
Pin Number - 1
Active Low - not checked
Spindle Setup
Relay Control
Disable Spindle Relays - not checked
Motor Control
Use Spindle Motor Output - Checked
PWM Control - Checked
Step/Dir Motor - not checked
PWM Base Freq - 5 (default)
Minimum PWM - 10%
This YooCNC control box has a switch on the back for "H" (hand RPM control via pot of front) or "M" (machine control via M3/M5). I never could figure out spindle control so I always run it in "H". Now I want to get the "M" mode working.
Questions:
Do the Output Signals Engine Configuration... Ports & Pins>Motor Outputs>Spindle fields need to be filled in if I want to use PWM Spindle Control? Para 5.3.6.3 says this is checked automatically depending on whether the Output Signals Engine Configuration... Ports & Pins>Spindle Setup>Motor Control Use Spindle Motor Output is checked. This is checked even if I want to use PWM Control. What would I use to fill in the Step and Dir Pin and Port fields
Since I want to run the Spindle via GCode, shouldn't the Output Signals Engine Configuration... Ports & Pins>Spindle Setup>Relay Control> Disable Spindle Relays box not be checked? Am I right here?
As I'm trying to get this figured out, do I need to input M3 and an "S" speed code every time i want to try it? Could i just use Spindle Toggle on the Diagnostics screen to make a quick check?
I appreciate any comments and suggestions.

Hello,
I have exactly the same problem, but unfortunately nobody has answered until now.
Could somebody help us?
Thanks and greetings from Finland,

Tom,
I still haven't worked out how to get spindle speed control of this YOOCNC controller with Mach3.
I resorted to adding a Solid State Relay (SSR) inline between the power supply and spindle jack. I control it with one of the un-used Output pins on a header below the Parallel port jack. Let me know if you want more details about how I connected it.

Hi All,
Just joined the Mach 3 Support Group.
I am having the same issue. Anyone solve this? I am in communication with the vendor as well to see if they have a solution (if there is one).
Good News: Received my 3040 CNC with 800W VFD Motor few days ago. I Got X,Y,Z communication with Mach 3 to work.
Bad New: Mach 3 software is not able to turn on/off the spindle or control it. Or even give me a read out on the RPM.
So far I can only control it manually from the inverter. The inverter gives me a Frequency Digital Display (Hz readout though that I can convert to RPM)
Thank you,
Robert
