Mach SDK plugin questions and answers. / Re: How to set Actual/Current Velocities from Plugin

« on: September 28, 2011, 03:57:19 PM »

Hi:

  Off the top of my head, I believe you set m_Engine->StatLast[axis] to an integer number of steps taken in the last 200ms..

Mach3 under Vista / Re: Win7 32 Bit W/PCI PP card

« on: September 07, 2011, 08:17:09 AM »

Beware the downside. ...

   While its nice the mesa does the timing in the 5i20 driver , it cannot do it to the reliability of the normal PP driver.
My original driver is the most stable thing in Windows timing.. the mesa breaks down over 35K and starts losing granularity.
  A new version that does it all needs to be able to buffer the data, it it loaded a few hundred ms worth of data on each interrupt ,
then it woudl work fine, but it must buffer. Only the original driver is stable enough to actually do a step on each interrupt.

  The backside is the mesa inetrrupts Windows to gets its attention, the PP driver interrupts the actual CPU to get ITS attention,
that small difference means the world in terms of wether a pci card needs to buffer or not..

  The current 5i20 driver will work fine, but only up to certain speeds, ( I wouldnt use more than 35K myself, maybe 45K.. ), so the
next card will pretty much have to be done as a buffering card by a plugin, with some simple driver used solely to transfer data
about.. Any new mesa would more resemble an SS than a PP type operation.

  Not neccesarily a killer point, but something for the next mesa developer to take note of. While Ive heard of the newer card,
I havent heard of anyone doing a plugin for it yet.

LazyTurn / Re: LazyTurn cuts where I don't want it to cut

Hi:

>>Lazyturn is no longer being developed...it is the way it is unless Art decides to modify or change it.

 , very true. I may add to it some day, but it was meant only to be a simple code generator done in a unique way. I have so many projects going on that
I may never revisit it, or I may decide to commercialise it someday so it can grow. But at the moment, even with its limitations, its a handy free utility, and its nice to see its
being used.
  I learn more about toolpathing and 3d every day, so perhaps someday it will all come together in a new project..

Might be the license file.. does it your name in it?  Illegal license files can randomly screw up pulsing that way..
 If its in your name thats probably not it though..

Dennis:

  Ill probably do one more final version when I can find the time. I need to fix one bug reported recently, and perhaps put
out the main profile as Gcode as Rich requested. ( Though Im unconvinced its really usefulll lol )

   The project was originally meant simply as a free utility for generating paths from a dxf.. Its pretty much there. It could go much further but I suspect Id have to dedicate a year or more and comercialise it to do so.. not something Im inclined to at the
moment.

Thx

Hi Dennis:

  Didnt see your question.. The last version made of LazyTurn is posted in the forum.. see previous post a few notes back on message number. But I believe its the same version as in Brians lazycam download..

GearoticMotion Preliminary testing / Re: Gearotica testing

Jeff:

  As yet, just the tutorial on outputs. Hard to say fromt he diagram exactly what you need, but the outputs page woudlnt be
used to match the gear really, just the design. Id design a gear with 42 teeth and play with the module or DP will you find one thats 1.7" in diameter.. thats probably the right gear .. but you can compare the teeth on the design page to try to match it to what you see.

   As to outputs, the depth per cut is 2.5d cuts, thats bascially the gearwidth on a normal gear. If its 4th axis the depth is the root depth, so you dont need to set anything..

Hi:

 ToGo mode is #333 , DRO display is a bit convoluted, 1018 appears to enter a mode that displays G92 work offset coordinates..

  Sorry, but tempest is simply a technology demo that isnt any longer worked on. IF you have questions I can probably answer them. Contact me at fenerty@artofcnc.ca

   Ahh, thats probably it.. maybe we always had 1 finish pass and its injecting after the first..

Ill try to get to it as soon as I can..
