Oh and what you are seeing with the + number when my spindle is up it's the WCS distance not the machine distance. Once the tool is zeroed in the WCS at the top of the material and I move the spindle up the number goes to a positive value because the work piece coordinate zero is now set to the top of the material. If I hit ALT D the DRO would display the machine coordinates and you would see a negative value on the DRO. Play around with ALT D and you will understand what I'm talking about. I know it's a lot in the beginning, but it gets easier with time.

Dan,

Appreciate the help. I am doing a show with my laser stuff today. Will have some time to work on this this afternoon or tomorrow. I did get a fixed touch off coming from Amazon so will get the going this week I hope. Be nice to do somethings with this machine over the holiday weekend.

Phil,

Can you give us an update on how this is working now?

E.g. are you using F4/Auto on the Part Setup screen; or are you using an M6 macro with a built-in probing operation; or are you using both, as needed?

After you do the probing operation (whether F4/Auto or part of a macro):
What does the Z position on the DRO read (when showing local WCS coordinates) when the tool tip is at/near the surface of the plate?
What does the Z position on the DRO read (in local WCS coordinates) when the tool tip is at/near the workpiece or spoilboard surface?
What does the Z position on the DRO read (in local WCS coordinates) when the Z axis is back up at home (Tool Check)?

If you are using a macro, and it is not the same as what you posted last Thursday, please post a fresh Report.

At a show today selling my laser engraved products.

Will update this afternoon when I get back to the shop.

Thank you

Hey guys,

So I fired up the machine when I dropped off my stuff from the show. The first thing I did was rename the M6 macro to take it out of the loop.

I verified I the the tool offset was 0 for tool 1.

I went in and used f4 to set my z height with the probe setting on the material and then added the thickness of it to the Dimension box snd made that tool 1.

When I ran the program it worked perfect with no errors but was .530 above the part surface. I then went into the PARMS and made line 71 0 again.

I did the auto touch off again with F4 and the probe on top of the material and ran the program. It worked perfect!!! I was just milling air and had to run but will make a few things tomorrow afternoon after I get done flying.

Now that I'm having some success I will run with that for a few days and then tackle the Macros and auto touch off after my fixed touch off gets here.

Thanks to everyone for the help. I'm not super smart but I am teachable.....

Marty, that last video you posted from CNC keith was very helpful. I had been looking for something like that. It summed up what I was trying to do.

Glad you made more progress.
Try and use the Wizard unless you are suggested to do otherwise.

Making more progress.

Am able to run a program and do some cutting.

Working on feeds and speeds. I have the VFD controlled by acorn at this point. I did the voltage test and it is working fine. 24k is 10 v and 12k is 5volts.

When I run a program that calls for 16k rpm the VFD goes up to 400hz which I assume is 24k rpm and the bit is cutting at too high an rpm and we get burnt wood.

The g code in the editor is calling for S16000.

I have the remote control p001 set on 1 for remote control and p002 set on 1 for remote freq control and the jumper enabled.

This a Hyuang VFD

Still not quite there but it’s much closer.

How do you know how fast the spindle is turning? Do you have a digital optical tachometer?

You need a way to measure the actual spindle RPM.
I have one and they work pretty well.
That way when you call a given RPM you can check the spindle.

Do not rely on the RPM in the Display on CNC12. Without an encoder, all it shows you is the RPM you commanded. For example, if you call M3 S5000
The display will merely show you 5000rpm. If you call M3 S 12000, the display will just show the 12000rpm value. With no feedback (spindle encoder) it has no way to know how fast your spindle is turning.

My initial gut is you don't have the VFD configured or wired to accept the analog spindle output from Acorn correctly....

Thanks,

No way to verify rpm. Only going off the 400hz the VFD is indicating and the behavior of the router bit in the wood.

Posted the question on CNc zone where they have a good Hyuang VFD thread going. I think I may need to set P070-p072 as if I was using a pot.

Should know soon I hope. Will have to order a tach.

I posted the parameter settings of the HY VFD. Used several and they work. (The GENUINE Huan Yang VFDs, NOT the knock off copies)

Order the tach.
