General Mach Discussion / Re: HELP! My Z axis is moving in chunk steps

« on: May 25, 2011, 02:16:37 PM »

Ok tried it with 20 lines and had to slow it way down, because 20 line is only about 1/16 of an inch.
With out it being slowed down it went real fast on fast movement
After slowing it down it readover half the line before it even moved at all.

So I then tried to make the movement a lot larger like .1 inch each and it still chunked the movements instead of a smooth fluid motion.

Is there a setting I am missing ?

BTW, it jogs very smooth and it you tell it in Gcode to move by it self up and down inches it is very smooth and continuous

Thank You

Yes the Z axis moves smooth if the line looks like this
N1000 Z 1.00;

Here are all my Motor settings
Z
Steps = 50911
IPM = 53.034
Accl = 2000

X
Steps = 1015.4
IPM = 49.99
Accl = 2000

A
Steps = 56.89
IPM = 6666  (is truely degrees of rotation)
Accl = 80000

Thank You

Yes the shaft that is between gearhead and ballscrew.
Or in other words the Z axis is moving 0.00292777388626453 in one move not slowly as the other 2 axis are

even if I run the G01 in front of each line that does not help
2 out of 3 axis seem to provide smooth linear interpolation.

To better understand I am machining the outside surface of a cone shaped fiberglass shell starting at the biggest diameter and working down to the smallest while the A axis is spinning. The real problem is it is leaving machining marks every time the Z axis lowers.

I have G64 in the start line

Majke one more mention, the DRO for Z axis shows slow continuous motion

General Mach Discussion / HELP! My Z axis is moving in chunk steps

« on: May 24, 2011, 10:41:08 AM »

Here is the problem.
I have a 4th axis machine where A is the chuck X moves the length of the object being machined and Z is the depth.
The A axis keeps a perfect continuous RPM and the X axis is moving constantly at say the rate of 128th of an inch per second and the servo motor for the X has a constant smooth rotation. However the Z axis servo is not moving except every few seconds and it then moves about 10deg instead of much smaller say 1/2 deg steps. Is there a setting I am missing or is my G-Code wrong?

A Few Facts
All 3 axis are Yaskawa Servos
Z axis is a ball screw driven by a 10:1 gearhead

Here are a few line of G-Code

Every once and a while I will get an error saying the smoothstepper has lost comunication with USB and you must unplug and replug in the board in and restart mach 3

I switched computers and it still does it ?
I have 2 boards and both are doing it ?

HELP!!

General Mach Discussion / Output control ? Parrallel or Grex or ?

« on: May 03, 2008, 04:40:21 PM »

Ok I have been using Mach 3 for a few years currently on 3 machines.
2 of the machines are running printer ports and the other a Grex

Is there a better solution as most new PC's do not come with printer ports and the Grex is loosing intrest with the developers.

My current Grex system need a very fast pulse rate and works great with the Grex
Except every once in a while it will start acting crazy like in the middle of running a file it will start jogging different directions and stop running the file.

Is there any new (relatively cheap<$500) solutions that do not use a printer port like the Grex?

Thanks
Curtis

Third party software and hardware support forums. / hubbard relay board troubles

« on: April 12, 2008, 04:30:33 PM »

I have several hubbard relay boards and I can not seem to get them working at all.
I set it up for pin 16 and pin 17 and then set up the outputs 1 and 2 for pin 16 and pin 17.
Set the spindle relay on for output 1 and the flood for on for output 2

I have tried all 3 boards so there seem to not be a board problem.


HELP?

Thanks in advanced
