OK you have to remember here in the US we are in a combo mode meaning metric and standard, i pump up the velocity to 3000 and then tried a rapid move through the jog control but the drives faulted out so i moved it down to 2000 seams to be OK with this amount i am cutting air right now with a file i have been working on and it seams happy also have Mach set in CV mode looks a lot better anything else you could recommend thanks again.

is that M for million or ? yes it is a large mill with some big power i don't need it to go at light speed i just need it to cut at a reasonable speed.
Thanks again for your help and response to my question's.

OK with that said then my thinking is now that i am way down on velocity @ 950 i should be able to increase it up to lets say 4K what do you think to high or should i go a little at a time and see what the machine will take what should i expect ?

Will this effect the actual movement in terms of part dimension's so hopefully i can explain what i mean using the midi line i do a move to check that the machine moves the correct amount say 25 MM and it dose will changing the velocity change this as i understand it that's in the unit's per correct me if i am wrong.

I have a Lagunmatic the servo motor are 500 in oz torque, 2500 rpm, V/K =40 V@120 DC i have them running on @ 50 Volts DC they have the normal pulley belt drive i had all the ratio's figured out but can't find it at the moment.
On the update version's i found that the graphics were bad and the arc's went wonky the present version i am using work's this is the reason i am afraid to change it.

One more thing i would like to say is i am running an earlier version of Mach i am afraid of updating it to the latest version as when i have done this in the past it screws up and i have a hell of a time go back to a version that worked so should i wait until Brian has the version 4 done ?

I got the machine through at least the test file so i could see what the code is doing and now i want to get a part actually cut in metal i was using a rigid foam for a test.
So first question how high can i go with the velocity setting i have Mach set at 3500 kernel speed i upped the velocity to 950 because i was not sure of how high to take it the other thing i need is to find a realistic speed and feed chart all your help is greatly appreciated oh and the machine works great it's the speed of maching a part that's the issue.

OK i will do just that also i just found something i stop the file and then clicked on the feed rate line typed in 600 it took it and now the machine is moving like i thought it should all along funny how you find thing's like that huh i got it going now thanks for all your help you and others are what makes this a great site.

So i am not sure what i need to do should i increase the velocity and the acceleration both and change a mach setting or ?
