General Mach Discussion / Re: LOST on setting up a servo motor in Mach 3

Hi, Archerks

This may be an issue with your BOB, I've always run my Gecko's direct to the P-Port, The Gecko's are internally OPTO Isolated so a BOB just adds double OPTO Isolation and complications to the setup in My opinion.

Are you running +5 volt's to the common terminal on your Gecko's as outlined in the Gecko Manual. ?

Theirs a note somewhere on the Common pin 13 and it saying +5 volt, The drives having "Common" are bi-direction OPTO's, With these you can Gnd or use +5 volt's the common pin 13 on the others you can't.

I think that's where the BOB issue Start's getting strange, Some BOB don't allow holding/floating, Hi or Low option.

Try wiring it Direct

Hi, Archerks

Change the Step & Dir. Low-Actives to Opposite State in Ports & Pins, Motor Outputs, The Steps Per should be 2000 X Turns per inch on your Ball Screw.

Start at a vel of 20 or so and Accel. of 5 and work your way up from there,

Make sure you have the Gecko's on a Good Heat Sink's / Fan cooled, You Should be able to turn the Limit up all the way up as your servo's are rated at 8.8 Amp's Cont.

Gain & Dampening can be tricky, Adjust the gain up till the motor start's to vibrate then adjust the Dampening up till it stops, Repeat this and run the servo's some, The Gain set's the Power/Torque  of the servo.

It's All a Balancing Act, Take it Slow. If you feel the geckos or motor's are getting to Hot, Turn the Gain down some.

Hope this Helps, Chip

Hi, Sh.y

Are you seeing a Pulse Frequency & Time in Int. values on the Diagnostic Screen. ?

Have you tried setting the LowActives "Step & Dir." States to "Checked" also. ?

On some control's you may need to select the Sherline 1/2  Pulse Mode, then Apply and Restart Mach3.

Hi, Sh.y

Post your Mach3Mill.xml file, It's should be located in C:\Mach3 folder, Make a copy of it and rename to ShyMach3Mill.xml.

Give us a little more info on your setup, Re-check your Ports & pin settings, Motor Outputs.

Hi, Sh.y

Your saying that if you click on Reset it still flashes Red, What version are you using.

E-Stop will all-ways be Green (Checked) in Ports & Pins, With 0 in pin # you should be able to Reset, Try checking the Emulated box and Port # to 0 also.

Hi, Sh.y

Set the Pin # to "0" should fix it, Don't forget the "Apply".
