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

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?

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,

Machscreen Screen Designer / Beginner Help

« on: February 19, 2012, 03:42:52 PM »

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?
