Mach4 General Discussion / Re: How to execute MDI?

Thank you for all the information!
It was absolutely user error. Flipping to the MDI tab and using Cycle Start was my issue.

@joeaverage what a deep dive, awesome!

I am half way through a program and trying to move the head. Cycle Start will restart the program. Is MDI only aloud while not running a program?

Mach4 General Discussion / How to execute MDI?

Recently I made the move from Mach3 to Mach4 with a hardware upgrade. Since the upgrade, I have been unable to use the MDI commands. I see the window. I cant type in the window, but enter and ctrl+enter won't move the machine. Am I missing something?

I am out of the woods, thank you. This is the most accurately I have ever calibrated a machine. Super stoked!

@Cbyrdtopper, thank you for the response. Using a ruler I was able to see that the mill is off by 1/16" over 20". I think where I may have been going wrong is that I am not preloading the screw in the right direction before taking my calibration measurement. Today I will try to move the screw 0.05 (in the measurement direction) to zero then measure my 1" with the micrometer. Maybe moving back and forth between 0 and 1" was adding backlash to my calibration. Additionally I will look into taking the backlash out using the screw adjustments.

Mach4 General Discussion / Calibration Issue
« on: July 14, 2021, 08:18:51 PM »
Hello,
I am finishing my my migration from Mach3 to Mach4. I just got done with calibrating my axis (without backlash) and noticed an issue. My calibration was done over 1". The mill is moving more accurately than I was hoping. The issue is when I move less than 1" there is a progressive error (not moving far enough). Once the machine gets to 1" it is perfect. I am unsure if the error continues on the other side of 1" but if it does, I would imagine the machine will be moving too far.

Anyone else run into this?

My conversion is complete! @Bill_O, thanks a million for the parts selection and the support. It looks like working in Mach4 is a big step forward. Now it is time for calibration.

Mach4 General Discussion / Re: PMDX --> VDF Grounding

Everything is working! There was an issue in my Mach / ESS config but I got it sorted (set the motor pwm and hope it maps). The ESS outputs 5v max but the VFD expects 10v. In the VFD I set the max voltage to 5v and now my spindle is working! My controller card conversion is complete! Now it is time to calibrate the machine...

@Steve,
Thanks for the information. I moved the ACM from 5v+ to the PCgnd. Still no movement. I have things set up (to the best of my knowledge) so that the ESS is producing a PWM signal to Port1 Pin16 on the PMDX-126. When I turn on the Would that produce an analog signal from the PMDX or is it not designed to be used that way? Do you know the proper ESS and corresponding Mach4 settings for a PWM spindle?

@Steve, Thank you for your response. I don't think I mentioned that I am using a PMDX-126. The relays are being used to change the spindle direction. I am open to picking up a 107, but I wanted to see if I could run my spindle from the ESS and 126. If I can get a variable voltage signal (via pwm or otherwise) from the 126 to my VFD I will be good to go. Maybe I am getting mixed up in the motor type selection and pin mapping.
