Could describe your spindle setup (I.e. is it just a +/-10V control, or are there any on/direction relays involved?)?

Also, probably best if you can post the relevant C programs in this thread, so they're easier to reference.


But, it does sound like something in your C code needs a change.

I think your header is the problem, as the KMVAR is different.

In your old defines, KMVAR was simply defined as 1, whereas in Tom's example, KMVAR is defined as PC_COMM_CCS_S, which must also be defined elsewhere, otherwise the compiler should throw an error.

You need to either change the settings in the relevant settings file, or use a different settings file. If you open Tool Setup, then select the Tool/Setup Files tab, the Setup File selection is what controls the default units when KMCNC loads. You can either switch to a MM version of whatever setup ...

I think I've now got a grip on this. I don't really need the ability to switch easily between mm/inch, as I'm sure most people never switch between units during normal running of KMCNC, so I just need to redo my offset calculations to convert to mm if needed. However I've just discovered a flaw in h...

Found a couple more photos. This is the original electrical cabinet- electrics-as-delivered_9861320395_o_resize.jpg It originally used a Baldor Eurostep controller with Parker stepper drivers (all rack mounted), along with a custom control card for handling the tool turret. As part of my retrofit, I...

Now that I've just had a quick look at the relevant code, I've just realised it's my code that's doing the conversion for offsets. After reading the offsets via the KFlop, I'm running them through the ConvertToUser function before displaying them, which given they're always unitless, is not a good i...

My current issue is, although I've still got the Unitsmm variable and associated functions still in my program, I mostly ignored it while getting the barebones of probing to work. It's only now I've tried using KMCNC in mm, I've realised KMCNC always outputs inches to my program. It's not a major is...

Thanks for that. I've just had a quick skim of it and it certainly looks good.

This was the first machine I ever fitted a KFlop too, and although initially running it on Mach3 for the first couple years (my previous lathe ran Mach3 with a SmoothStepper), after yet another crash where Mach sent the unlocked and spinning tool turret into the still spinning spindle, I finally jum...
