PoKeys / Re: Pokeys I2C Fuctionality

« on: April 14, 2013, 07:52:16 PM »

Thanks, I took a look at the specification document. I understand the structure of the data, but I don't understand how to interface to PoKeys from Mach3 using VB.

If it is possible, can you please provide some sample code.

Thanks,

PoKeys / Pokeys I2C Fuctionality

« on: April 13, 2013, 06:56:56 PM »

Hi,

I have been successful using the PoKeys utility to interrogate a TMP75 sensor using the 56U. The next step would be to try and write some code in Mach3 to see if I can communicate over I2C.

My problem is that the documentation is a not very specific on the command structure. I am using Version 17/1/2013 manual. Page 62 lists the commands, but no additional data. Other commands do have some additional information (SetPinData as an example on page 104).

Is there more information available that I am missing? If not, has someone successfully used the commands and can help me with some code snippets?

Regards,

Geo

I tried the G04P0 command, and it works - Mach waits until the command is executed in the window before it switches over to the next fixture.

Thanks for the tip. I prefer your method since creating M codes is not very clean.

No, I have not. I am hesitant to switch to another version since this one is stable for me, except for the reported glitch. My current work around is to define an M code M59110, with Code "G59P110". Mach3 seems to wait to implement the G59 switch with the M call, so that works. I suspect Mach is not actually screwing anything up when it switches over with look ahead. I will give it a shot with fixtures that are an inch different in height. Should be obvious if it plunges or retracts in the middle of a cut.

General Mach Discussion / Work Offset - Strange Behavior

« on: December 12, 2012, 10:50:22 AM »

Hi,

I have a fixture where I use a probe to set G59P110 and G59P111 prior to machining.  The parts have a Z-offset that changes by a mil or so so due to fixturing variation.

I program the G-Code to machine the first part using the P110, then switch to P111 and machine the second part. The problem is that Mach3 switches over to P111 before it has finished the first part. I think it might be due to look ahead. I verified that the offset actually changes by looking at the work offset screen, and could see the z value change when the P110 changes to P111.

There are many ways to work around this, but I was wondering if this is a known problem, and if there is a fix available?

Regards,

Geo

OK, I think I have some working form of it. I have been around Mach3 about 24 hours, so I am sure there are issues in the code, but the basic idea is there.

This is only for the DROs. Maybe someone has advice on how to send text to the MDI?

Yes, MachScreen.

Machscreen Screen Designer / Touch Screen Functionality

« on: February 19, 2012, 04:30:18 PM »

Hi,

I would like to set up Mach with a number pad on the screen so I can enter data into MDI and DRO without a physical keyboard. I have seen some examples where a keyboard pops up, but I would prefer to have a static keypad displayed on the screen.

I suspect I will need VB code to accomplish this task, but was hoping for an example that I can reference.

Any help will be greatly appreciated.

Regards,

Geo

Thanks Gerry, that worked.

Just for completeness:

For Reset Button, I used function "Std Reset", Standard Code 21. Also used LED function "Reset LED", OEM-Code 800.

For Jog Button, I used function "OEM Jog Mode Toggle, Standard Code 103. LED function "Jogging Enabled LED", OEM-Code 83.

Hi,

I started playing with MachScreen, and can get the DRO, reset etc to show up. When I load in the screen in Mach, and I do reset, I can enter X1.0 and see the DRO respond. I cannot, however, get the arrow keys or number keypad to make the DRO move.

I assume I am doing something simple wrong here?
