General Mach Discussion / Switching to a water cooled spindle like to use relay for turning pump on.

« on: November 21, 2020, 06:36:11 PM »

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.

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.

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.

General Mach Discussion / How to reset Mach3 to the original complete default

« on: August 08, 2020, 06:36:18 PM »

I purchased a new mach 3 and after tuning motors and edge stops  I can get nothing to work and everything is getting worst. I like to know if there is a way to reset the entire software to factory default and restart all the calibration again.
I will really be appreciative about any solution.
