Just to update with more info I thought of, the voltage measurements taken on the G540 were with the wires disconnected from the MC60 controller.

The MC60 controller does indeed have 11.9 Volts coming out of it (at the potentiometer connections) as it should, which according to Mariss and Peter, should be fine to use with the G540.

Of course, I was getting ready to pull the benchtest G540 apart, and decided to test the pins on that but that reads basically the same way with no change whether the spindle is on or off, so I don't have a clue.

What pins and voltages should I be checking and looking for?

Thanks,
Dave

Ok, tried the S3000 and nothing either so I decided to try a bit of troubleshooting some more here. I have a feeling my G540 may have some issues after checking the VFD outputs but I'll see what you all think.

When the spindle was off, the pins checked as:

7+8 =35 mV
8+9 =38 mV
7+9 =0 mV

Spindle on at 3000 RPM:

NO Change at all. 

So I think I'll switch out the G540 with the one that I bench tested (that worked) and see what the result is from that.

I hate troubleshooting.....   

Thanks again-
Dave

Absolutely Jeff,

What I'm not seeing is any movement at all on the Machine PC. On my bench test, I have 3000 typed into the "speed" DRO in Mach 3 so when I hit the "spindle" button, it's starts up and increases until it hits the 3000 RPM as shown in the Speed DRO. I can increase it or decrease it with the Speed overide arrows perfectly.

When I connect this the same exact way on my main machine PC, I get no movement at all. Now keep in mind as I mentioned in my first post, the benchtest G540 is working perfectly, the Taig Lathe G540 which connected to my main machine PC is the one that shows no movement.

Thanks,
Dave

Interesting, that's a start, but just as a note, it did work with that setting on the bench so I'd be curious to know what/why that is.

I certainly do appreciate your time and will have a look when I get into the shop tomorrow-

I have not as of yet as that was part of my original question. I have no idea what half the settings mean. I've looked at the manual but not much help to me. I didn't want to go randomly switching things around as not to screw something up on my main machine PC. I thought maybe there would be an obvious setting to change but I can't see it.

Thanks,
Dave

Hi Tweakie, thanks for the info, but no scope here.
As for the spindle, when benchtesting it, I turned the spindle on (Mach screen Spindle Button) and it worked perfectly, once I inserted a speed into the Speed DRO

So the screenshots of Mach look correct to everyone?

Thanks guys-
Dave

Hi Jeff,

No sir, no SS, just the typical Parallel port-

Thanks,

Hi all,

Ok, I have my little Taig CNC Lathe torn apart, and I'm ready to fire up my MC60 treadmill controller with the Gecko G540. Now Peter Homann already helped me with the wiring (thank you Peter!) but I need to know exactly what changes to make for setting up Mach.

Just a bit of background info for you. I've already tried settings from a user on the "Zone" that worked when I benchtested this setup (although I don't think the speed is correct), HOWEVER, that was with a completely different G540 and treadmill controller, although they're the same exact units as what I have installed on my Lathe. It works perfectly on my benchtest setup, but for some reason, it's not working on my actual Lathe setup. Basically as you can see by the diagram below, the vfd connection from the G540 acts like the potentiometer. Peter gave me a great idea to install the switch to be able to manually control the speed, as a nice alternative.

Keep in mind, the PC is fine as this is what I use to run my Taig Mill and my Taig Lathe, every day, with no issues.

I'm thinking I should ask you guys before I go screwing something up as I've tried to understand what each setting means but I'm at a loss as to what is actually controlloing what. I'm actually wondering if the G540 VFD control may not be working on my Lathe controller but unfortunately I'm not that bright to know for sure,    I may just take the G540 from the bench test and try that one to completely rule that out, but then everything would have to be completely ripped apart for that.

Here's a diagram of what I have at this point for wiring (it's a bitmap so it will take a bit to download):



Now while I'm sure changes would need to be made to get my motor running at the correct speed, here are the screen shots that I followed:











Thanks as always,
Dave

Hi Phil,

I don't use that program either but a few things to also check:

-Make sure you're exporting 1:1 scale
-Make sure you have the drawing at 0,0 origin

I tried using Solidworks for drawing turn work but never got the dxf just right, so my cylindrical piece ended up looking like an oval piece because I didn't have the origin at 0,0.

Hope that helps-
Dave
