OK...I am new here......and usually work with Big Machines......but my question is related to the Hobby Machine I am playing with.....( TownLabs TL518)

I have a great CAD program for doing complex Surfaces....( Rhino )
I have a great CAM system for doing toolpath generation...( Madcam plugin for RHINO)
Simulation in MADCAM tells me I have a 50 min cycle time for Z level roughing.....( GREAT!)

Code output from Post processor is ok ( lots of X movements {with no other AXIS changes} written as a bunch of small steps....uuugh)

ACTUAL RUN TIME ( even using G00 command lines)........over 8 hrs.......

BOTTOM LINE.....THE THING IS JUST BARELY MOVING!!!!

What is creating this problem???

My Guess.....

the small steps do not allow the ACCEL/DECEL curve of the drives to be over written in the smoothing algorithm....hence even though my feedrate is set to 2000mm/min, actual traverse is more like 100mm/min...

How do I overcome this??

Play with motor tuning?

Any help appreciated!

Tweakie.....

It is all the time.....also, the delay from when you stop pushing the button to when the axis actually STOPS moving is like a second or more......seems very wierd.

I bought a used machine ( Townlabs TL518) using Mach3.....running under a build of R1.  Brought it home, loaded R3 but now it doesnt operate.

Issues....

I tested my LPT port, but it finishes ( i think) and the screen disappears, saying Mach1 test complete....so did I pass???
Jogging the machine......all axis are very jerky......

Ok....where do I start now to rectify this glitch?

Motherboard of the PC is an Asus P4B.....LPT is running ECP....

thanks in Advance......
