  thanks tweakie

  i have always want to make a pirates ship hmmm
  well back to work.
 I'm trying to understand, i guess it will be (offsets)   when i air cut my first circle i did not know where it was going to cut it out on the table.  
 the good part i have feed rate control.
 i really need to know  how to operate this machine safely
you have great day   
don't hurt yourself with your bug zapper

 well Dave it has been a good day
 i got my cnc to cut a circle little flat on the sides  i have a little play here and there i will tighten it up  hope fully that will make my circle a little more round   .
  need to get my  cnc where it can repeat
 i will start getting some pictures  together  you are going to have to help me post my pics i don't know how to on this site
 (my stuff  back yard cnc ) but i  have very much enjoyed this
i sure didn't know what i would have done without some of the guys in here helping me
 taig has a lathe chuck with a large spindle bore out now with a indexer  on it  that's the one i would like to make my 4 axis with  in truth my tail shaft on my taig lathe  it is so loose
  I'm very interested on how you got your lathe in tolerance

 got it guys at least some of it
  in the mach 3 addons in the tool  properties select surface speed  i was right clicking carbide  by doing so i  auto sets surface speed no matter how many IPM you put  in
 other part not fixed  how many ways is there to set feed rate
 motors are not running warm now   i did my fist cut  the circle  little flat on both sides   (my new  next problem)   
 i learned today
 motor profile  150 IPM
thank you rich and jerry 
i could  not of done it with out you guys

 hey rich Gerry
 Gerry this is what i have build your own cnc black toe 2ft x 8 ft x and y chain drive #25 chain 9 tooth sprocket's 1/4 pitch steppers set at 1/16 1.5 amp's 36 DCV  all the same on z axis except acme 10tpi with 5 starts
 i tuned motors i have normal toggle controls  speeds   any speed a person wanted my next posting i will say what i have motors set to  
  when running g code I'm very slow even when i use override the feed on mach3 s i not sure what to do now
i found how to set motor profile in the manual that i have read 20 times and over look 20 times (sorry rich)  i am a slow learner
I did set motor velocity and accell 
 installed Multie leads for pyrometer on all motor's as soon as i can get my feed rate to what i think would be normal operating speed i will know if i really have problem with motor getting too hot .
 i was worried motors being wired incorrectly i have check my wiring it is  Good i didn't want to burn a motor up
i have normal toggle speeds
 still to slow running g codes  
i will reread what you guys have suggested and the manual again
I'm not sure what i have over looked or done wrong?  on   if i need to fix this by tuning the motors again  or if it is me not setting the feed rate properly
 before when Y axis  motor getting warmer than the other motors i had to put my hand on motor to feel if it was turning
when running g codes the cnc is not running to the motor profile's
this is where i am reading in the manual 5.5.2 to 5.5.4
 thank you  
mikee

  thank you rich
  i have my motor drivers set to 1/16  at 36v  1.5 amps . 
   (velocity)  Setting
port pins. motor tuning.motor movement profile, velocity slider. is this where i would set the velocity 
 if possible   i am not  wanting to start guessing on setting's for the material  i m wanting to  cut  (exotic hard woods) and MDF .
  is there  a good starting point on settings for speed and feeds
 
i have a 2 1/4 hp porta cable  variable speed router 10.000 to 23.000 rpm  i have a 3/8 dia 2 flute router bit .
 
for my first  cnc cut i was thinking of 6 in circle cut at  0.0100 depth

in the tool properties # 5 calculate speeds  and feeds  when i right click on this it dosent seem to change anything. 
i can see  that i am jumping around guessing at this.     
i keep on thinking  surface speeds  for some reason . 
ok im going to change velocity  
if i am skipping steps  please get me going in the right direction  this is hard for me to understand i cannot tell you how many times i have read manual 
thank you 
mikee

y axis motor is alot warmer then z or x motors 
 homing and ran  first simple program or g codes  2 D 6in  circle air cut no tool  feeds and speeds  are way slow
 like gear oil in winter slow    had cnc turned on 1.5 hr   i cannot tell you exact temp at this time  motors seem to run ok         
 is it normal for one motor to run warmer than the other  is there normal opeating temp 
please advise
