General Mach Discussion / slave axis and home switches

« on: January 25, 2019, 01:20:26 PM »

Hi Again
with some guidance from a very helpful guy on here i managed to configure my home switches that was until i allowed the y axis which is controlled by 2 stepper motors one controlled by a slave axis "A" to travel in a negative direction to the switches . Mmmm  don't think  so 
 The slave axis has a mind of its own at this stage . I guess im trying to figure out here how to get the slave axis "A" to run in sync with "Y" to the home position.
Iv'e checked the motor tuning and all is well, i didn't really expect any different as the machine runs a dream when running code .
Any help may just give me a good nights sleep

Hi
sorry i have lead you down the wrong path here .
I am fitting home switches one on each axis and  highlighted as such in mach 3 ports and pins . i have noticed that the function for "auto set of the ports and pins " is not there very strange this may have made things a bit easier .
After allot of homework i wired each switch to the individual pins and all 3 earth wired to the earth point on the board as i am lead to believe that a parallel circuit is for limit switches ,maybe this is right ?.
I have not yet set up soft limits until i home the machine to the switches .
Im sure im doing something completely dumb here but time will tell , so frustrating 
thank you for your input

Hi TPS thank you for your response
.. i have wired 3 limit switches as NC . taken cables to board and wired as follows all earths to earth point on board , x axis to pin 10, y axis to pin 13 and z axis to pin 15 . In mach 3 i have assigned each axis to port 1, pins respectively.
 settings are saved and when a switch is manually pressed the yellow light indicates that mach 3 recognises the settings .
However if i jog an axis to a switch it is not activated. I assumed i made some headway since my previous post but seem to have hit a wall again .
kind regards Jon

Hi i guess im pretty much in the dark here ?. Thats correct i have seen active high/active low but for the life of me i cant find any other information or appear to get the answer to my question hopefully someone might point me in the correct direction soon ?

Hi
 just setting up home switches on the cnc.
A couple of shady areas i need to cover before final connection .
i have x y z switches installed working N/C "normally closed " and have identified pin 10  X ---pin 13  Y ---- and pin 15  Z, and earth point on the breakout board.

 My question is i can highlight these pins and number them on the inputs in Mach 3 but am unsure if there is a setting for N/C or N/O i assume if its a signal to the board it isnt relevant maybe you could clarify this for me
Thanks in advance
Jon

Thank you both i have used RS before they are a great company to deal with , and thank you for the heads up on cable choice very helpful

Hello i need to find   a reliable source for limit switches in the UK to install on one of my cnc routers . what cable should be used  im led to believe this may be an important factor
regards Jon

Hi Craig the machine was built for me in poland , a very reliable machine i might add but without switches fitted . I have progressed from simply jogging to my xy and z and zeroing out and need to set a jig to cut multiple blanks , as you can imagine this is near on impossible without an accurate home position to reference from to the same point each time . I understand the importance of these switches however my knowledge of fitting them isnt quite as good as my hands on experience in the building trade . I assume its straight forward and maybe i need to contact the supplier with regards to pins to connect to ? i dont honestly have a clue

so i assume without home switches Mach 3 will be unable to store G55 through G58 fixtures to call upon when setting up different  jigs  in different areas on the table
TPS ill give the idea a go
BR549 this would be like manually choosing an xyz reference point for a 1 off job and zero out am i wrong  ? but if i carry out a job to a  jig   i cant recall the initial settings for that jig
Its a steep learning curve and the hill is getting steeper
