Cycle Start not beginning program


Good Evening!

I'm having an issue where my programs will not begin when I select cycle start at the beginning of a cut or when a tool change is called. It's been doing this since day one that I got my machine working so on software version 3.42 and 3.43. I'm using the MASSO post processor for Aspire (inches). I'm sure I'm doing something stupid... any help[ will be great.

Full Description: Cycle start does not begin the program. I have to hit single block then cycle start until my spindle turns on. Then I turn single block off and back on. It then moves to the beginning of the program. I select single block and again, cycle through the first few lines, turn single block off, then when I hit Cycle Start the machine runs smoothly.

I have been making separate files for each tool needed because when it calls for the tool change, I will change the tool and hit cycle start or CTRL+S and nothing will happen. If I press single block, it moves to the beginning of the program, which does me no good lol.

Below is some of the code for a program requiring a tool change. First tool runs fine with me completing what iI stated above.

Okay, it started the program after hitting rewind lol. After doing a tool change im still having issues getting it to start up. spindle starts up, goes to x and y... then stops

again, probably me being stupid.

Below is that portion of the G Code.

Hi g0browns

I'm not sure what the issue is at this time and i don't know if you have the auto tool zero set up but could I get you to watch this video and see if it helps. It is well worth setting up the Auto tool zero and it will allow you too change tools very easily.

There are no known issues with the post processor that would cause this issue that I am aware of.

Could you let us know your Masso serial number and software version

could you also post the full Gcode file for me to have a look at.
