General Mach Discussion / 4 axis problem?
« on: May 10, 2020, 04:34:35 PM »
My 4 axis is not running smooth anymore?
 see movie: https://www.youtube.com/watch?v=L74mRiVAt54

first I jog the axis...   and later I give a A360-A0-A360

it is not the toolpad... If I give in mdi a A360 - A0  it is turn in steps?

What is wrong?

General Mach Discussion / Mach3 and 4 axis...
« on: May 25, 2017, 11:56:52 AM »
First, I'm not that good in English, but I try to explain my problem...

I'm "playing" with my 4 axis.... but ik have so problems, and I don't understand why I goes wrong...

normally if my tool is broke.... I push feed hold.... jog Up....   change the tool.... jog to a position to zero my z-axis, en press cycle start.... Mach3 shows a pop-up... I push oke... the z-as goes to safe z... x,y goes to the place I was wen I push Feed hold... I press Cycle start again... and I go on with the job.....  (maybe is this procedure wrong? but It works always alright..)

now with the 4 axis.... push feed hold.... change tool...zero my z-axis.... press cycle start ...pop up .... push oke....    and the A-axis start to turn?!?   why?....    I didn't turn in with jogging? 

also normally if the tool is broken... I push feed hold, and then reverse run, so the machine is back by the place where the tool was broken.... and then I'm change it, and start again with the procedure I explain in the top of this topic....
but now by the 4 axis....  press feed hold... press  reverse run....  and here also the a-axis start to turn?... the tool goes straight through my already machined workpiece ????

what do I wrong?  is it something in the configuration?   please help!!

General Mach Discussion / 4 axis problems
« on: September 12, 2012, 04:48:11 PM »
I've recently a 4th axis on my machine... but It don't works alright .....
I make toolpad with visualmill 6.0... 

first a mill then top, then rotate 90 degrees, mill the left side, rotate 90 degrees again ....etc... etc..... so i mill the 4 sides.... and this works alright....

but then I want to finish, to let the A axis to rotate, and mill the outside...   but that did not go oke...  the A axis keep turning, and the Z-axis don't move alright....
it seemed like the A-axis goes  via wrong side to the next point .....?

somebody tell me , to turn on the "Shortest Rot"
but I can't found that?

It must be in the menu : "Config>State"

but I don;t have State by Config ???

so , is there somebody that Knows what can be the problem? and where i can found "Shortest Rot."?

sorry for the bad english!

General Mach Discussion / home and limitswitch problem...
« on: May 09, 2012, 05:12:43 PM »
I don't know it anymore....

on every axis i have 2 limit swiths on 1 input....

and in mach3 I have home, ++ and -- on the same input.... so I use 1 limitswitch also for homing....
and this always works alright!!!

but now I change something on my machine, en I connected a longer kabel on the stepper for the z-axis.... (thats al i did...)

but now homing don't work not anymore?  if I home my machine, first start the z-axis, goes up, and if the limitswitch goes on, then I get a stop on the limitswitch... ...

before the z axis go down a bit, so the limitswitch was free, and the the y-axis start homing....

what is wrong now? Why go de z-as not a little down anymore?

(and if I shut off home by the z-axis, the y-axis and x-axis don't also not working anymore, and also keep staying in the limit switch. And I not change anything on the x and y axis???)

please help... what is wrong!

VB and the development of wizards / is this possible with mach 3?
« on: December 07, 2008, 06:18:18 PM »
I'm a lot on a Dutch CNC forum, en someone make this:

but the guy is anti Mach3 , it looks like a pinball machine...  ;D

is there someone who can write a wizard or something to do this with MACH 3?

i know he do it with a bol/sphere frees  and a for next loop... everytime the tool goes deeper in the material... the circle it makes grows bigger....

(sorry for the bad English)
