dah79,
I have a Pokeys 56U, which is listed as a 57U when you upgrade the firmware. The latest plugin for MACH4 is 7.29.0.2914. The plugin in getting better but still has numerous issues. If all you have are dedicated switches and an MPG you will be able to get this to work. I have several segments works for example a matrix keyboard, I can get keys on the keyboard to perform functions like Feedhold and that works perfect. I can also get the LCD display to update if I write to the global registers under the Pokey plugin. I have been able to output to LEDs which are in a matrix configuration from Mach4, which works fine as well. The challenge is if you are using Matrix keyboard you can't access these and assign these inside the pokeys plugin, but if you use dedicated input pins or output pins that stuff seems to work. One issue is enabling and disabling the MPG, that is not available by default in the plugin, they do have something called a deadman switch option which is for the MPGs that have a button you hold in while using the MPG. My MPG does not have that style switch so getting it to work correctly has been a challenge. I have hard coded that switch in the plugin saying always ON, and been able to jog a given axis with the MPG. You have to use code inside of MACH4 in the PLC script and Signal Scripts and Screen Load scripts to get this stuff to work. Unfortunately, there is no detailed step by step instructions available or video where someone setup a pokeys pendant. I am trying to get this done, since moving over to MACH4 from MACH3 will not happen if I can't get the pendant stuff to work. I opened tickets with Polabs of many issues they responded and said they would investigate and then never responded again. The learning curve in MACH4 is pretty steep, there are a hand full of experts that have their machines working and they have been coding LUA to make things work. DazTheGas has posted many videos and honestly you will learn a great deal about how MACH4 works by watching his videos. He does not have a Pokeys device as I asked him questions since he is an amazing resource who has shared far more about MACH4 and how to do things than the writers. The manuals for MACH4 are very thin, nothing in comparison to MACH3 which have very detailed manuals. rumor has it that Newfangled solutions was having them written professionally but MACH4 has been out more than a year now and nothing. As I get the basics figured out I will post some instructions.
