Mach4 General Discussion / Re: Mach 4 DRO Reading Incorrectly

« on: May 02, 2022, 12:33:21 PM »

I am in incremental Jog mode.  I have experimented with the jog rate% to no avail.  I also contacted mach support and received a message basically stating "you cant just set the motor to move 1 unit and expect it to move 1 unit.  That's not how its supposed to work."  They also suggested "looking into tuning your motors" This is neither an answer, or even a relevant response, to my inquiry.  Even if the motors were grossly out of tune (which they are not) I don't understand how that is relevant to Mach4 not moving 1 unit, which I have defined via the steps per unit calibration, on the DRO once commanded to do so.  Instead it shows a movement of 50 units...

Mach4 General Discussion / Mach 4 DRO Reading Incorrectly

« on: May 01, 2022, 12:43:12 AM »

Hello, I am running Windows 10 Pro 64, Hicon Ethercat Motion Controller board with 750watt servos on a refurbished old Bridgeport Series 1 CNC.  The kind with the fixed ram.  I have setup Mach 4 to communicate with the servo drives which are Leadshines, which it does well.  I have set all my units to inches and calibrated the 1 unit movement to equal exactly 1" of measured movement using a dial indicator.  However, for whatever reason, the DRO in Mach 4 shows approx 50 inches of movement for every actual inch of physical movement.  When jogging, I set the movement to 1.000 jog increment and hit Y+, the Y axis moves in the correct direction exactly 1", and the DRO shows that it has moved approx 50".  Also, I am in G20 mode which can be seen at the bottom of the screen.  Any help here would be much appreciated.
