ability systems' software

[indianvirus]

hey guys hi again...

i have bought ability systems' software for controlling my router but its too slow. it gives rapid upto 1.3 meters/min. only. it took me a while in getting friendly with it too. is this good enough should i try more or chuck the whole thing????

i have heard Mach3 CNC gives abt same speed... is that true?

Sorry I don't know anything about Ability Systems' software.

With Mach3 it depends on your steps per unit and the pulse rate that your computer can put out (maybe other factors as well).

Steps per unit is easy enough: it's easier to move the machine quickly if the steps per unit is low.

Pulse rate is related to steps per unit. First some easy math: 60 inches per minute is 1 inch per second (I'll use this measurement since it's easy for me. 1 inch per second is equivalent to 0.0254 meters per second or 1.524 meters per minute.)
If you want to move the machine at 1 inch per second and it needs 40,000 steps per inch that means your computer will need to send out 40,000 pulses per second. If all three axes are moving at 1 inch per second the computer will have to send out 120,000 (120k) pulses per second. BUT, if your machine only needs 4,000 steps per inch (10x less) then the computer will only have to output 12k pulses per second (also 10x less).

As far as I know the fastest you can set Mach3 is 100k (for a single parallel port). At 40,000 steps per inch that 100k limit translates to roughly 50 inches per minute (~1.3 meters per minute) max for all 3 axes. BUT if your machine requires less steps per unit, say 2,000, that would translate to much faster possible speed, 1000 inches per minute in this case.

Mach3 has a pulse rate setting in its options, the default value is 25k if I remember right. Perhaps the Ability Systems software has a similar setting somewhere in its options?

thanx hirudin

thanx alot my friend...
its easier to understand now.
