CS-Lab / csmio/a offset problems

« on: July 03, 2016, 12:12:26 AM »

Hi I am trying to tune a CSMIO/A to a analog servo motor and the offset value on the PID tune  is randomly  changing from .012 to around  +3v , i can see this on my CRO their is no axis command during this time .
Any ideas
Peter

CS-Lab / CSMIO -A following error

« on: May 18, 2015, 01:23:00 AM »

Hi
 I am retro fitting a Biesse Rover C9 router with the analogue version of CSMIO , I am very impressed with the functions of CSMIO and I am at the servo tuning stage
The servo amps have been tuned for Peak PID , however , the CSMIO following errors seem to be too large
What is a typical max Following error , the attached picture shows the following error and MAX Acceleration , the axis have a sharp response

General Mach Discussion / input pulse from laser to drive Mach3

« on: September 05, 2014, 12:21:44 AM »

Hi
I have a fiber laser and want to interface Mach3 to mark many small objects positioned on a large X/Y table , its not an X/Y plotter type but galvo based with a field frame size of 100 mm x 100mm so can only mark 1 object at a time.
I want to automate the process via MACH3  and load a table with objects and start the laser and sequentially mark and complete all  objects  in one pass.

The laser has an output pulse when the laser mark has finished and an input mark to start the laser .
what I would like to achieve is to have a macro that  starts the laser from an external pulse then when the laser has finished to move to the next G code , then when moved and stopped send a pulse to the input of MACH3 to start the laser and then repeat for the total objects on the table

has any one any ideas on how this can be done

please advise if further explanation is needed I can draw a timing diagram if needed

regards peter

General Mach Discussion / laser Text software

« on: October 13, 2013, 08:09:59 AM »

Hi I have built an 80 watt CO2 laser running off Mach3

I have a project to laser engrave 1000's of small name plates , the text data I have been given  is populated in an excel spread sheet.

Does any one know of a software that imports excel text to a raster based Gcode so I can run off Mach3, I could convert all to one raster  image but this would take hours to engrave .I noticed  Epilog software only converts the test to raster which reduces engraving time !

Any suggestions on what software is used with Mach 3 with a laser for small text only label engraving?
