No. It is almost impossible to do without disabling, aka using the spindle PWM circuit. The MX 4660 doesn't support two independent PWM circuits. The TTL+ line, however, can be easily managed using...

Hi John, Pretty much. I have been researching big time. Here is one site will question and answers are found Endurance lasers. We produce and sell powerful and efficient diode lasers (solid state)....
Thank you john-100. The laser is the Endurance.com 8w laser. The power supply is a 12DCV 6A I ordered from eBay. It showed up today, but unfortunately, it was a 19DCV 3.3A power supply. So it went...
John-100, this is very helpful. When asked about a "controller" earlier this was what I was talking about. The installation manual was rather lean in the details. Here is the link to how to control...
Maybe it's the definition of a controller. It has a 'controller'. If you feed it the 12vdc it will work. The laser comes on, the fans run, and the beam hits the wall. It also has a TTL input to...
The laser is an 8 W from endurancelasers.com. The power supply will be independent and operate at 12vdc 5A or so. The laser has a TTL on-off control. Making that work with the MX4660 is the problem....
Thanks, John-100. I have studied these pictures for hours. I have already set up my spindle with RPM control, all the limit switches, and the auto zero. I am at lost on how to control the laser light...
"The output + and- terminals are a simple ttl switch". I am trying to connect a laser engraver to an existing CNC machine. It takes external 12vdc 6A to drive the fans and power the laser. The laser...
Good catch Ger21. The motors move!! Need to tune them. They seem to stall. Now on to the spindle. The spindle is a PDS Colombo 220V 5HP air-cooled version. The VFD is a Delta VFD037B23A. Both are...
Thank sparkness & Ger,
The motors are not locking up when the G201s are powered. The issue is definitely somewhere in the C10->G201 connection. The jumpers are set correctly and I jumped the...
I recently acquired a used 5x10 aluminum cutting CNC. In the previous life, it used WINCNC as the controller. I scrapped that and installed an ESS -> C10 BOB driven by Mach3. It has G201 controllers....
Appreciate all the help I received about a year ago. Spindle has been up and running perfectly with the MX4660 along with close enough speed control. Today, it died mid-job with an E.CO.A error. Past...
Any thoughts by anyone?
I got the 4 Channel 5V Relay described in this post. Is there a 6 pin plug that will fit the GND, IN1-4, Vcc input pins? Or how did other people connect to this Relay? Thanks.
Al,
Adding the .01uf to both the X & Y switches seems to have solved the problem. Running for days now without fault. Thanks for your help.

The metal enclosure is earth grounded and everything else is connected to it. There is connectivity between all the components as measured by my fancy new digital volt/ohm meter. It reads 7-8 ohms....
No it's not shielded. The error message is "External EStop Requested". I thought adding the .01uf may have solved the problem but it didn't. Sometimes it runs for hours without problems and other...
Thanks Al,
No, I do not use the H58 magnets. Haven't seen the LED light up or observed an indication on Mach3. I put a .01uf as shown on the spec sheet. Have them on hand. If that doesn't work, I'll...
Hi Al,
Using Digi-Key #55110-3H-02-A-ND
Everything pretty much works except for a weird limit switch issue. I use hall effect switches. On the Y axis, the sensor is mounted so it moves over the magnets. One magnet is used for Y Home and...
Yes. Look at Figure 15. The MX4660 allows you to use a different pull-up voltage for the inputs if you like -- this can be handy if you want to run 24V powered IO, etc. If you are using just...
Maybe I wasn't clear in my question. "DC" ground as coming from MX4660 is not the same as "earth" ground coming from the AC side of things. With my spindle, I have to connect an alligator clip to the...
Quick question. On my ESS, MX4660, 2.2kw spindle setup, I have to use a separate clip-on wire ground connection to the spindle to zero the bit. This prevents, as far as I know, the auto-zero of bit...
A_Camera,
Thanks for the input. What you are calling a "brown" wire is actually the 14/3 copper ground that pwers the vfd. The green ground is the 16/3 leading to the spindle. The 14/3 white wire is...
Mac, Thanks for your help. I now have 16/3AWG from the VFD to the Spindle. It's flexible and runs in the chain. Tomorrow I will connect the pin 4 to the spindle, reset VFD to factory default and...
Ok Mac, I got a new digital meter and yes the Pins 1,2 & 3 show 1.4 ohms between them! My original meter would have measured it correctly too, IF I had simply zero the ohms reading 1st. Lesson...
Thank Mac,
I will buy a new meter tomorrow and retest. Thanks for all your help. Dave
Thanks Russ,
I mis-spoke. What I said about the Ohms was backwards.
Ok. I received another spindle from the manufacturer. It is sitting on the table. I checked the pins.
Pin 1 to Pin 2 : o.o...
When I get the replacement, this will be the first time I check/do. Thanks for your help. Dave
I am in touch with the vendor. I informed him of the same results. Hopefully, we can swap spindles. There was no connectivity between pin 4 and the spindle body. Why in the world woulda manufacturer...
