First post here, I hope I don't mess up :-)

I began using emc2 for my little PCB milling about a month ago. It's 
great! It works very well, and best of all I can use networking of linux 
to get files, as opposed to floppy and DOS with turbocnc.

I have a little question though. When comes time to drill my PCB, the 
CAM programs tries to use many drill size and so I must change tools. 
For this, I must manually change the drill. I tried to put a M0 
immediately after the M06 command to give me time to change the drill. 
The problem I have is I just can't get the program to continue after the 
M0. The "Run" button on the Tkecm interface start back from the 
beginning, "Resume" seems to work only with "Pause". In the manual, it 
is said that one must use the "Cycle Start Button" to continue after a 
M0 or M1 command. Where is this button?. If I take a look at the 
"demo_mazak" project, there is mention of this, but I just can't find 
where is the linked pin to the HAL interface. They create a signal, then 
link this signal to a hardware pin, but not to a "software" pin.

Am I missing something?

Ah, and while I'm here. Is there any way to slow the backlash 
compensation? I have little backlash in my mechanical device and when 
changing direction, the axis "bang" at what seems maximum speed to 
compensate for backlash. I'd prefer a smoother action. Is it possible?


Thanks
