You have a feed of 100 in your example yet you say your motors tuning is 80, am I reading this right?

The F100 sets the feedrate to 100% of the maximum which is 80 inches per minute. Speed of G01 at F100 = speed of G0.

Well no expert on code but F100 to me means go at 100IPM or in my case 100mm/min. As your motors are tuned at 80 they will only go at 80 but I am just wondering if that could cause a prob.
Will test out tomorrow in anycase.

A feed rate of F100 is 100inches /minute or 100mm/minute, if it worked as you say you could never work out thread pitches for tapping or any other type of pitch controlled work.

I've always had the F command implemented as a percentage of the maximum speed (guess that's what happens when you roll your own), and hadn't noticed the difference between 80 and 100 yet (I've had mach3 running for... oh... 3 days now). So actual velocity eh...so that's how the real world does it. OK.  :D

Just had a quick look at your xml. You sure you have your motor tuning correct  1875IPM for X and Y and 4687 for Z seems a little on the fast side ;)

No problem, was just thinking it must be a high speed machine ;)
 I notice you dont have limits set up. If your Home switches can be activated at either end of the travel you can use them as limits as well. When doing a homing move Mach will use them as Home switches, all other times it will see them as limits.
Dont see anything else wrong so far, well your use of Z home as pin 10, usually pin 10 is for the E-Stop button but that will depend on your breakout board and also how you choose to set things up so not really a concern.
 You might want to mess a bit with the velocity and acceleration as my mill has  accel of 40 so yours is half that and maybe that is where you are seeing the pauses from.

Part of your problem may be that you are at 800 steps per inch... this is very low and can make the system seem odd...

Other then that all is good and I see a very small pause but nothing that is very long at all.. You were saying 1/3 of  a sec. I am seeing about 1/10...
