Mach4 General Discussion / Re: Add a laser to my CNC

« on: January 31, 2016, 05:30:18 AM »

I am following your progress and will be most interested to learn how you get on with changing the S#### (and thus the PWM) to switch your laser beam on / off.  In Mach3 the command is certainly far too slow but it is many times faster in Mach4 and it may work well.

Just from an initial look at your .xml may I suggest the following…

Config. / Ports & Pins / Motor Outputs  -  change Step Pin # for A Axis from 5 to 8.
Config. / Motor Tuning  -  reduce Velocity for both X and Y axes from 400 to 300 & save each change.
Config. / General Config  -  Uncheck Use Watchdogs,  Increase LookAhead to 200.

Please see if that makes any difference.

Hi Lawrence,

If you post your .xml file (the one located in the Mach3 folder named <your profile>.xml [typically Mach3Mill.xml]) copy and rename it to lawrence.xml then use the 'reply' tab and Additional Options to post it. Then we can check you Mach3 settings and hopefully see if there are any problems with your set-up.

SmoothStepper USB / Re: Availability

Still available and still excellent support (Mach3 and Mach4 compatable).

My advice would be to order direct from Warp9 http://www.warp9td.com/

General Mach Discussion / Re: Help Needed with MY 3040 cnc machine -Z axis Problems.

« on: January 28, 2016, 05:15:39 AM »

Hi Bob,

In a word 'no'

Slow jog is by default set at 80% (I think - long while since I made a fresh install) increasing it to 100% will give maximum speed. The 'shift' key overrides the slow jog setting making it 100%.

In Motor Tuning, the Velocity of each axis should, ideally, be set 30% lower than the speed at which the motors nearly but just don't quite stall. Similar with Acceleration.

Within your Gcode the G0 / G00 moves are rapids and the axis will travel at the Velocity set in Motor Tuning - the G01 / G02 / G03 moves are at the Velocity determined by the Feed-rate which has been set (within the Gcode program) by the F#### command.

The Mach3 manual explains all this much better than I can. http://www.machsupport.com/help-learning/product-manuals/

I am pleased you have found the problem.

You are not the first and you will not be the last to discover that a loose coupling is the root cause of many problems 

You cannot get rapids faster than the set velocity, however, try holding down the shift key when jogging if this increases speed then the Tab key will bring up the pendant display where there is a Slow Jog Rate % which you can set.
