Hi Larry,

Nice to hear from you again.

There are disadvantages with that particular board...
1) It needs 12-24 volts in order for the EStop (or any other inputs) to work.
2) The EStop switch needs to have 'normally open' contacts (most are 'normally closed' contact).

Perhaps a different breakout board would be the best option ??

Hi Jodi,

You can check that you have the steps per unit set correctly for each axis by using the Axis Calibration feature on the Settings (Alt-6) screen.

Velocity and Acceleration are pretty much a trial and error thing - increasing Velocity in steps until the axis movement is unreliable then reducing the setting by 30% then setting the Acceleration figure to 10% of the Velocity figure. From that point fine tuning to obtain optimum performance.

Hi Craig,

To my knowledge no list of the Mach3 pound variables was ever released.

One switch could be used sequentially but not for both Homing and limit at the same time, it would be a pointless.

Hi Jodi,

In Config. / General Config. I recommend that you change your Look Ahead to 200. In addition you may need to experiment (to get the optimum performance) of your CV Control settings - This document will give you more details on this http://www.machsupport.com/forum/index.php?action=dlattach;topic=7923.0;attach=6168

Hope this helps.

Hi Jodi,

Bottom right of your main Mach3 screen is the Profile: that you are using.

Look for that name.xml in your Mach3 folder.

Hi Jodi,

Your Gcode runs just fine here so it could be that your Mach3 settings are causing an issue.

Could you post your .xml file - the one from your Mach3 folder named <your profile>.xml then your settings can be checked. Copy and rename the file Jodi1.xml before posting.

General Mach Discussion / Re: Need help with ports and pins

« on: March 24, 2017, 03:08:36 AM »

The Port 1 Pins Current State Led's don't always work as expected so they should be ignored.

If Output#3 LED flashes then that is OK.
When you measure the output voltage on Pin 17 the voltmeter should be connected between Pin 17 and Pin 25 (or any pin between 18 and 25).
Check that you have not allocated Pin 17 to any other functions within the Mach3 set-up.
Check that Signal GND (LPT Pins 18 to 25) is connected to GND on your breakout board.

You cannot duplicate pin number functions without causing a conflict. If you are using Port1 Pin2 as your Spindle Step pin then you cannot also use Port1 Pin2 for Output#1.

You have probably seen this already but by far the simplest solution to using PWM laser power control is described here :  http://www.cooperman.talktalk.net/files/27_files/Page1020.htm
