mach3 turn simulation?

[tracebender]

Sorry if this has been covered before but I can't seem to find an answer. I've been using Mach3 Mill for a while on my X2 retrofit; even before I got the hardware running I could use the tool path window to write small Gcode programs and see how they would execute.

I'm starting to look at a lathe retrofit now and I'd like to begin getting familiar with the Mach3 turn before the actual hardware is ready. The problem is that I can't get any code with feed rates to run because they are tied to spindle speed. Is there a mode in Mach3 turn where you can simulate the spindle speed to check out the toolpath without actually having the spindle speed sensor input?

there are two types of feed mode in mach 3 one is feed per rev and one is independent to spindle speed. I have run a lathe under mach without a spindle sensor. Check the M-codes that are set.

Thanks for the response. It appears as though the default feed mode in Mach is feed rate per minute rather than per revolution; the code I had specified feed rates per rev (like G01 X-0.0625 F0.01) but did not set the appropriate mode with a G95.

Also, it appears that without a spindle tach you can set the spindle speed directly by inputting a value directly into the S DRO. The combination of these two things has allowed me to continue checking out the tool path of some code I'm working with.
