Mach SDK plugin questions and answers. / Re: Dual Boot XP & win7 32bit can't install plugins on win7 d drive access denied

« on: July 27, 2013, 10:53:15 PM »

If it's not a security permission issue, copy the Mach3 folder to the C drive, and install the plugins. Then copy the .dll files from the C:\Mach3\plugins folder to the one on your D drive, then delete the Mach3 folder from the C drive. The .dll files are the plugins.

I would suspect that it might be a security setting issue, though.

Make sure your pulley speeds are set to 0 min and 22,000 max.

I think I got a little confused myself?

Are you sure the parallel cable is straight through?

Sounds like you have the G540 wired to the VFD incorrectly.

You mentioned three pins from the G540 to the VFD. Those three are for controlling the RPM. Pin 17 is NOT one of those three pins. It should be used in addition to those three, connected to control start and stop on the VFD.
Sounds like you have pin 17 wired to where pin 14 should be??

Disable Spindle Relays does just what it says. It disables the spindle when it's checked. Leave it unchecked.

Pin 17 should be set to Output 1. This turns the spindle on and off. Make sure Output 1 is assigned to Clockwise (M3).
Under Motor Control, check Use Spinle Motor Output and PWM Control.

Pin 14 controls the rpm, via PWM, and should be assigned to the Spindle Step Pin.

Male sure in Config > Spindle Pulleys, that you have Min Speed set to 0, and Max Speed set to 24,000. This allows Mach3 to send the correct voltage for a given RPM.

(There are three VFD pins on the g540 - high, common, and signal.)

The manual says Ground, Output, and +10V.

Make sure your getting +10V from the VFD.

The set the spindle speed to 24,000 and make sure your getting 10V on the output. (Pin 8?)
Then set the speed to 12,000 and see if you get 5V on the output.

I don't have a G540 and VFD, so can't help you with wiring or VFD Settings. Having all the correct VFD Settings is also very important.

You might want to post your .xml here so someone can take a look and see if anything obvious is set wrong.

What are the actual machine coordinates when you see the error?

General Mach Discussion / Re: Auto Tool Zero / Touch Plate issues

« on: July 24, 2013, 04:49:20 PM »

Also, I hard-coded the plate thickness, since GetUserDRO(1151) also always returned "0" (I entered the thickness in both of the "Gage (sic) Block Height" DROs in the Offsets tab -- why are there two anyway?)

Does your screenset have a DRO #1151? If not, you'll need to add one for that call to work.
The two gauge block DRO's each have a button next to them, that have different functions. The buttons read the data from the adjacent DRO's. One button is for setting the Z zero position, the other is for setting a tool length offset.

The main issue is that GetVar(2002) always returns "0" regardless of where the probe touched.

The probe is actually working, but it's not setting the DRO?
How are you checking the value of GetVar(2002)?

Try adding

msgbox ZProbePos

after

 ZProbePos = GetVar(2002)

and see what you get.

Again, post the link to the Ebay router.
Without knowing what it is, nobody can tell you if it's any good or not.

Some people say that with a little work, some of the Chinese machines on Ebay are very solid. But they often need the electronics updated, and a thorough inspection and sometimes minor repair or updating. But they can be had for a good price, and make for a solid base. But don't expect a great running machine out of the box.

There really aren't any heavy duty routers that are smaller than 24x36. And at that size, the price will be above your budget. Something like this.

Also, you can specify the feedrate of your probing moves. Have you tried increasing the feedrate?
Unless your machine is literally not moving while the script is doing calculations, the feedrate could be the issue?

I think ive got one pinned down. Its a cnc router 4 axis for 2drive screws on y axis w gecko,380 motors and buy mach 3 software. its on ebay by cnc conversionkits .

post a link. I looked for this when you posted it, but couldn't find it.

what is the best i can get for mostly metal work ,3axis for aprox. $5000+/-.

Whenever someone asks a question like this, a router would not usually be the correct answer.
And a lot of the routers I've seen on Ebay are less than desirable.
