Thank you for previous questions I had and the help everyone give me.
Today, my question is:
I purchased a water cooled spindle with a VFD controller and all this is controlled with a dongle purged on a USB slot.
I am not using the relay to turn the router on and off with M3 and M5 any more.
My question is can I use the same relay I used for the router to turn the water pump on and off? Change the command to that output?   
My VFD is the Huanyang. Perhaps there is a way to connect the VFD directly to a relay to control the water pump. 
Also, I like to turn on a valve to turn high pressure air to blow the chips when using the CNC to cut aluminum
Thank you for any help on these questions. Like always I do really appreciate any help.
Mario.

G-Code, CAD, and CAM discussions / Re: mach 3 tool offset issue
« on: October 24, 2020, 02:10:16 AM »
I have a problem with tool offsets.  I been cutting parts and adding the tool radius in the code that is way to much work. I know there is an automatic tool offset. I, for example, made an endmill tool #1 diameter of .250 and store as a permanent tool. On the code I add a line T1 however, the tool follows the center line of the code path? what gives?

General Mach Discussion / I can't reset machine coordinates
« on: August 25, 2020, 12:53:48 AM »
I send the machine home and, after it gets there, I can zero the dros with no problem. When I press and activate the "Machine Coordinates"  button the dros are set to the the middle of the table. I try to zero with the buttons, nothing happens. Try by pressing the home button, nothing happens.
Yes I have home switches and everything else works.  Without homing the machine coordinates I can not activate the soft stops, already entered the values and activated the Y and X not the Z.
Well as a new user I need a bit of help. Thank you.

My name Mario,
Retired mechanical ing. Work with Caterpillar products all my working life.
I am a hobby woodworker now and I built most of the  machines, including a 19 inch band saw, in my 2 car garage shop.
My newly built CNC machine 2x4f  is working ok but there are some questions that I have about Mach3 some times.     Well thank you very much for helping me and all us the newbies.

I think I did not explain myself properly.
When I home the machine, it will travel to the top right corner  anything from there down and left are all positive numbers.
fNow, if I go to config> stops/soft spots and check reverse direction box I can reverse and come to the left bottom corner,however, at that time any time I move the gantry  in any direction will change the numbers to an increasing negative.
I spend all day trying myself to and every time I try another change is not good.
If I move the X gantry to the right yea.. when moving left works but is on the wrong side. The Y is the one that the only way to change is to moved to the top of the table.

Please help    perhaps I can post some photos if is not explained right

General Mach Discussion / my cnc on mach3 homes to the positive
« on: August 18, 2020, 05:17:59 PM »
My cnc homes to the right, looking from the from of the table. To the positive.  I need to start on the left corner were it will be home 0 and from there I could move anywhere on the table and always have positive numbers. I reverse the motor wires, reverse the motors on pins  Wherever I make home on the 0.0 is on the left.
Is there a way to change the true homing on the left? Make that be the true 0.0 and everywhere you go on the table will always have Positive numbers.
I am talking about the short X axis across the front of the table.

I will check the option of reduced current on stand by. Right now what I did was to install  bigger motors than needed ar a reduced current; they are working just fine but I am afraid and I turn off the power supply to the drivers in standby.

Thank you all for everything, and being willing to share with us ,"newbies", your knowledge and experiences.

Sorry; however, I forgot a detail that may be significant.
Before, when I was running the demo version for about 3 years I never had the motors locked up, with current flowing, after the program stop or before start..... is there some difference in this regard on the register version and the demo one?
