Hi, everyone

I have code generated by the circular pocket wizard.  The code is to dray a spiral (attached below).  I am faced with two problem;  1st
I need the router to go from outside to inside - the code generated by the wizard is in to out.  Can you help me configure the wizard or help modify the code so that the distance between the spirals is maintained ..
2nd
I need to modify the code so that the inner most spiral does one more turn without affecting the other spirals (I need to fill the center with the fluid I am dispensing)

Thank you in advance for your help.  The code is below (I use a valve to dispense fluid rather than a router - the A0 is for the valve that dispenses the liquid - opens-closes:

%
(Pocket Size = +13.0 - GIVES 13 IN DIAM CIRCLE)
( % Step Over = 30)
(Ramp Dis = + 0.5, Feedrate = +500)
(Tool Diam = +4.0)
(sTEP DEPTH = ?)

(GIVES EXCELLENT RESULT AT 8 - 10 PSI)

I tried it, it does.  Thank you so much for taking the time.

Thank you so much, Hood.  This is a great help!

I just generated the G-code; I am trying to understand all the params, reverse the direction (it now goes from in to out).  I trully appreciate it.  If you know where I can get a legend for the params and/or some documentation, it would be great.

THank you!

Hi, thank you for your replay. 

I am afraid I am not familiar with "the circle pocket wizard".  I am totally new to this.  Will you please guide me as to how to do this and what to use ...

Thank you.

Gentlemen, thank you for taking the time to address my question.

What I am using is a CNC router (from K2CNC) which I am using to dispense glue on a board in a spiral manner.

I was able to correct the problem.  It turned out that the speed was very hign and the acceleration low (set to 45 ...) When I increased it to 80, 90 and then 100, it worked.

Now, I have another problem, the G code I am using was written by this guy I no longer have the contact info for.  I believe it was written using Master Cam (code listed below).  The code was generated using a tool-size of 1.5 (with the assumption that the successive spirals - of dispensed glue - have a bleed of 1.5 inches, so that the successive spirals do not touch each other).  The problem, however, is the "bleed" varies depending on the flow-rate, the height from which the glue is dropped, the viscosity, etc. 

In short, what I need is code that I can run with different tool size (gap between successive spirals).  How do I modify the G code and have versions for tool-sizes of .75, 1.0, 1.125, 1.25 and 1.5?  I do not have the software to generate G code, what can I do?

I much appreciate your help. G-code is below:

Hi, I am a new bee.  If I posted this post in the wrong place, please let me know and direct me ...

I was attempting to draw a spiral using the MACH3 software (latest version) and two G201 stepper motor driver  with G901 multipliers.

When the cnc draws the spiral, at low speed, I get even spirals.  When the speed (velocity/acceleration) changes, the spiral becomes flat-edged at the X and Y axis because it all of a sudden jurks the arm ... When I repeat the same run again, it repeates the same pattern exactly - with the error (so, I am thinking it is not missing a step.  Is that assumption correct?)

Pleas ehelp.

Dan
