General Mach Discussion / Re: Delay between lines of code

« on: October 11, 2013, 10:18:09 AM »

I tried moving the feed rate to a different line ahead of the code, and I increased the acceleration as high as I could get it before the steppers would skip steps.  This reduced the hesitation, but not completely.  To me, if the motion is to be linear, it shouldn't matter if there are a number of lines code to get from point A to point B, with look ahead, the motion should be absolutely smooth.  I can't figure out why there are these little hesitations.

Rotational soft limits is the only one that is checked.

I have it set as 360 degrees per rotation.

I've varied the acceleration to the maximum I can get, on down.  I can't have jerks in the table that the a-axis is controlling at all, let alone between lines of code.

I am not trying to activate spindle at all, in fact it isn't even active.  Btw, I am using a Geck0 g540.  To activate the laser I wrote a macro, but I am trying to get smooth rotational movement before I worry about turning the laser on and off at given points.

I have searched and tried everything I can to fix this problem, but I can't find a solution.  Here is my program.  Yes, I can write this all as one movement without a problem, but I will be inserting macros to turn on and off a laser, so I want to test movement first.  I am running in metric, I have all CV controls turned off, I have tried turning on one at a time and changing values without any luck.  I continually get a slight delay between each line of code which causes major problems with our laser application.  Any help is appreciated.

General Mach Discussion / Mach3 G540 analog output

« on: March 07, 2013, 10:44:58 AM »

I am a real newbie.  I have a 4-axis kit from CNC router parts.  I am really only using two axis' right now.  X and A (for my application).  I have these running great.  My problem, is that I need a 4 volt analog output.  I thought I would be able to do this with the VFD output, but I have had zero luck so far.  I need to trigger the 4 volts on and off just like motor switching on and off in the g code.  Any suggestions on what to try?

TIA.
