General Mach Discussion / Re: Spindle Delay?

I just set the spin up delay to 10 seconds (I'm still so new to machining that extra time isn't a huge concern to me) and now everything working great!

Ah, thanks Hood.  Yes, I'm using a VFD.

Okay well I'll bump that spindle delay up and check that checkbox!

General Mach Discussion / Spindle Delay?
« on: May 28, 2013, 02:25:32 PM »
Hello all, I just got my registered version of Mach3 and I finally cut something on my CNC which was a big moment and a huge relief :)  I have a question related to my spindle though (1.5kW Air-Cooled Chinese) and the time it takes to spin up.  I think this problem is pretty obvious and I think I see where it needs to be adjusted but I was hoping to get some quick confirmation and maybe a little bit more verbosity on the options (or, of course, if I'm in the wrong area altogether!).

I am using the PMDX-107 to control the spindle, it works great and takes commands from the MDI interface.  The problem is that when I load a program and start it, the program begins cutting before the spindle is fully up to speed.  Right now I am manually setting the spindle and turning it on via the MDI panel (using s20000 & M3 for example) and then cycle starting the program.  This works but is a pain in the butt (and sort of defeats the purpose of the 107 since I have to mess with stuff instead of it all being run from the gcode)

I noticed that in Ports & Pins, the Spindle tab, there is a section for "general parameters" which lists "CW Delay Spin UP" which defaults to "1 second".  Is this where I would put in something like "10" seconds to make the CNC wait for 10 seconds after the s20000 and M3 commands are issued at the top of the gcode file before it starts moving into the piece?

If so that's great and I'll change it to an appropriate number higher than "1".  2 follow ups would be: 1). why would you need a longer spin DOWN delay? and 2). What does the "Immediate Relay off before delay" checkbox do?

Thanks in advance!
