I redone the backlash with the servos and no more problems with the circles. Thanks for the help.

I replaced the steppers with servos and it still stops during milling process at 12 o'clock, 3 o'clock, 6 o'clock and 9 o'clock. Plus the circles are still not round.

Why would it pause four times during bore or pocket? Plus the hopes are still not round.

What control mode do I use? It has position, velocity and torque.

Moving from stepper motors to servos. Just no clue what to do.

I am new to the servo game and I was wondering what I have to do to set up the drive for a Bridgeport. Tuning and parameters. Do's and Don'ts!

I have my servos and I want to set them up what do I have to do?

I want to check for backlash on my cnc converted bridgeport but I don't know how to go about it because I don't have linear scales. How can I check for backlash in my x and y axises?

I lowered the feedrate and I tried 300 down to 160 and that didn't fix my issue. It got a little better but not 100%. I did adjust the knee gib but haven't tried it. Plus I do have servos now and...

Thank you

Thank you. What about torque?

I want to upgrade to servos and I was wondering what is the lowest torque I should avoid. I have been looking and all seem low to me.

Or upgrading to a closed stepper would be just as good?

Mechanical
Backlash or binding, No
Overloading the motors, Not Sure

Electrical
Bad Signals/noise, No

Tool path/G Code
Feed rate
Too aggressive tool path

I am boring with an end mill using the quill as my z.

I have a Bridgeport J Head mill that I converted to a cnc. Installed ball screws on the x, y and z. I doubled checked my calibration on all axis and all is good.

I am using the Masso G3 Touch with...

Where can I find a good video or info for learning the laser engraving and cutting?

I have no Idea what I am doing.

I will check the drawing again and verify my zero's are in the right spot. Thank you mactec.

I am having a couple of workspace issues. The picture and a video can show you the problems I am having.

I want to turn my axis manually with my machine on and Mach 3 on and when I do I can't turn my axis manually. Any ideas on how I can do this? Does it matter if my stepper motors are 4 wire or 8 wire?...

I am using 2d cad. Have you used that one?

How can I resize my box? X Y and thickness?


Thank You Nathan

Thankyou awerby

I need some help with my tuning of stepper motors. I have the excel file I seen on here to do the calculations but not very clear on what I need to put into Mach 3.

Here is the link of what I...

Great!! Thank You!!

Does it matter if I stepper motor left or right side on x axis?

Thank You
