Mach4 General Discussion / Re: Is somebody here who has expiriance with a mach4 handwheel

Hi Bear
I use a Vista CNC - iMach PS1A-S Pendant which works wonderfully with Mach 4. I have nothing to do with the company except as a happy customer.

Hello Guys
Could we have an addition to the Jogging Panel to include MGP jogging with an axis selector, jogging mode and a step size.
Thanks

Thanks Steve, I'll have to put some thought into this.

Mach4 General Discussion / Setting Spindle Speed Range

« on: May 23, 2016, 03:42:34 AM »

Hi Guys
Could someone please let me know what is the method for setting the Spindle Speed Range - I can see it on the diagnostics page but is there a method for normal use on the run page. I have a Charter Oak clone RF45 with a six speed gearbox and will need to change ranges after some tool changes. Is there an "M" code or something?
Thanks
Steve

Mach4 General Discussion / Spindle Feedback Ratio

« on: May 20, 2016, 03:04:37 AM »

Hello Guys

I have Mach4 - latest version - going through an Ethernet Smooth Stepper with their latest plug in, driving my spindle through a PWM signal.
The motor behaves wonderfully and seems to be very accurate to the commanded speed.
I have an index input signal from a slotted optical switch which I also believe works well.

My trouble is wildly varying spindle speed read out on my screen. When I look at the machine diagnostics page I see the Spindle Feedback Ratio changing constantly - it is set to 1 in the config settings and I just want it to stay at 1.
Is there any way it can be locked at 1?

Thanks
Steve

Hi Mate
Unless I misunderstand what you want to do - I think all you need to do is set a tool length offset before each job. Set the tool height to the current job requirements and Mach does the rest. - Look up "setting tool length offsets" or "setting z offsets" something like that.

In my part of Australia it's been between 35c and 40c (95f to 105f) for a while now and no rain for over a month. Still I would perfer to be here then where you guys are.

General Mach Discussion / Re: Rotary axis position issue

Hi WHT
I have the servo and a harmonic drive - it looks about the same as yours, mine is 100 to 1 and about 5 1/4 inches in outside diameter. Its a Harmonic Drive Technologies HDC 2M 100 2A. I was planning to mimic my lathe spindle with a D1 4 chuck mount so I could use the same chucks as well as the collets that go in it (5C).  I have been thinking about how to get it all together for a few months now. You have given me some inspiration with yours.

Is your belt drive 1 to 1 or something else - I was planning on 1 to 1 with my servo's encoder having 10,000 positions I didn't think I would need more resolution and at 3000 rpm at the servo I could still get 30 rpm at the chuck which should be heaps.

Please tell me more about your brake - like what cylinder did you use - a commercial one? and where you got it. Does it automatically apply when the spindle has stopped?

The CAD drawings would be good to look at - if you wanted to post them here - others might get some use from them as well.

I take it from your web site your a Kiwi - Bad luck about the Cricket - bloody South Africans smacked us too in Oz.
