Slow PC:
Time in Int - 3.3 jumps to 8 occasionally
Pulse Frequency 1400-1600

Fast PC:
Time in Int - 7.5 jumps to 14 occassionally
Pulse Frequency 12700-14000

Since this morning the rig run by the slow laptop isn't actually moving at all, when I touch the bed of the test rig I can feel the stepper motor jolting away, but the bed of the rig itself isn't actually moving.

Yes, even if I turn the velocity up to silly amounts on the slow laptop but it still runs the steppers motors at about 5% of the speed of the fast laptop.

The code is identical, at the moment I am just testing a few mm in each axis. The first code is

'x-4 y6

then I use

'x4 y-6
x-4 y6

for the rest of the day.

All drives & motors are identical


Morning, here are the XML files

On another note, this guy seems to be describing the same problem as me http://www.cnczone.com/forums/mach-lathe/140829-cnc.html

Here is a video of our test equipment (just for fun, no useful information here) https://www.youtube.com/watch?v=q1GqtryA96s&feature=youtube

General Mach Discussion / Mach3 stepper motors running at super slow speed
« on: February 05, 2015, 10:16:46 AM »
I have two JIGs which I run with two similar spec laptops. One laptop is slightly faster than the other, however whichever JIG the slightly slower laptop runs is incredibly slow, even when velocity and acceleration are turned up to stupid amounts. All the settings are the same on both laptops, does anyone have any idea why this is happening?

Laptops have around 1gb of RAM, dual 2GHz processors, and fresh wipe and install of XP

General Mach Discussion / Getting Mach3 to start/stop on system clock
« on: November 26, 2014, 02:53:41 AM »
I have a series of mechanical tests that need to be run inside a test chamber after every cycle. I would like to do this automatically but I will like it to start/stop based on the computer clock rather than a delay set by G-code, is this possible?

Many thanks

I cleaned out the CPU fan and it works fine, thanks for your help. I should have thought about the hardware in the first place

General Mach Discussion / Computer running Mach3 turns itself off
« on: August 29, 2014, 03:46:17 AM »
I am running a simple Mach3 program on a capable PC, but after 1 or 2 hours into the program the computer turns itself off. Its not a power issue or a power settings issue, and it shuts down at different points of the program every time. The program is a 10000 cycles of back and forth between the same sets of co-ordinates. Can anyone help me?

Thank you for your help that worked.

Using my current stepper motors I have calculated it will take me 80 years to complete my test schedule! can anyone recommend some fast stepper motors? ideally with integrated lead screw? if I run my current motors any faster they loose steps. I don't need a great deal of torque, the test rig simply moves a 10kg steel bed around.

I am using these http://www.acpd.co.uk/cgi-bin/site-editor.pl/8/-ecommerce?action=item;item=7230R011;eid=P422748

General Mach Discussion / Simple subroutine 'too many nests'
« on: August 05, 2014, 07:55:23 AM »
I have a really simple X Y set-up, but when I try and run a simple subroutine 1000 cycles or more it tries to create the tool path and an error message comes up telling me there are 'too many nests'.

Is there another way to run this simple program on repeat? or to get around this error message? I need to be able to leave it on for 500,000 cycles or inifinity

I used the automatic steps set-up.

When I use a high speed/vel I am loosing steps. Is there any way round it or is my hardware mechanically limited? I have no information on the maximum speed of the motor
