 OK the start code or first line of code in the file reads as follows G00 G49 G40.1 G17 G80 G50 G90 G21 don't see a G61 and yes they are all short moves

I am a running a program right now and this is what has led me to the fact that the machine is running so dam slow it's taking forever to cut the file is there a way to increase the speed right now or stop the machine and make a setting change or something.

So if i understand correctly if i increase the velocity this will move the axis faster in the code it has both G00 and G01 i am using a cam package to generate the code file.

OK i see now so if the G-code calls it out at say feed rate of 80mm then no matter what i do in the FRO the machine well only move at the feed rate set in the g-code is this correct, if this is so then if i change the feed rate in the g-code to say i don't know 300 and then i find this to fast how can i slow it down do i  have to stop the machine and edit the g-code to a lower speed i thought that's what the FRO was for ?

The machine is at 790 steps per unit and what i mean is on the mach screen there is a setting to increase the feed rate i have it at 300 right now.

I had to change the kernel speed back to a lower speed of 3500 because of what i said above it would fault out the drives at the higher 4500 kernel speed so i set it to the lower 35 and no problem the machine runs fine just slow i have mach over driven to 300 % it's still moving slowly i timed it the machine travel is about 85 MM in 20 seconds i don't know but it seams slow to me.

It's very steady around 3500.

Hi Hood
Thanks for the quick reply, the machine operates very well and no problem with the processing of G-code but i want the machine to go faster if i increase the kernel speed in Mach the machine moves faster but then when it calls for a rapid move the machine studder's and the drives fault out.

Hi Guy's
 Trying to get some more speed in the X&Y travel  I am using servo motor's and gecko drives i have tried upping the kernel speed to 4500 but when the machine dose a rapid it faults out the drives is the speed and the computer CPU speed connected do need a faster computer to get more speed out of the machine or is there something else i am over looking.
Thanks
Dennis
