Hi, JB

I think, Most of these machines are 380 volt 3 phase, Did you get a transformer with it, 220/440 to 380 ?

You may be able to drive the spindle with a VFD 220 1 ph to 220 3 ph control.

As far as the steppers go, Ether make a interface board for the driver boards or use Gecko's or other's types out there.

Post some pictures of the stepper cont. boards, spindle control and basic layout.

I looked on cnc-zone didn't find much, http://www.cnczone.com/forums/showthread.php?t=14548&highlight=emco+120p .

Just a Start, Chip

Hi, Dave

What Version are you running, Look under Help/About Mach3 Cont....., There were some issues in ver. 3.00 smiler to what your describing.

Try turning down your feed-rate override on Program Run screen also.

Thanks, Chip

edit: Missed the part on "have hooked up steppers"

Hi, Ed

Did you use g00 moves or Shift + Arrow key to tune your Velocity & Acceleration settings ?

On the Program Run Screen what's your Feed-rate set to ?, Hit the TAB key, What's the Slow-Jog Rate set to ?

If thay aren't set to 100 then your tuming is probably off.

Use Home & Limit's to reverse any axis that run's the wrong way.

A little TLC should fix it.

Hope this Helps, Chip

Hi, RC

It appears to be a BUG, The A Soft Min will set the box for Z , But the rotational perspective is way off, Even with the same value set in Z soft min.

Ver. R3.033 hear

Thanks, Chip

Hi, Saumur

LazyCam works in Units, If your DXF is in MM, Then it's MM in LCam.

Thanks, Chip

Hi Carlon

As Hood sead, Sounds like your soft limits set wrong.

In the first pic, Toggle on/off soft Limit button, "Green border" is ON.

Pic 2 is Config, Home & Limits setup screen, This where you need to change settings, Defaults are 100.00 & -100.00.

Pic 3 is Config,  ToolPath Configuration screen, This where you turn on Machine Boundaries ( White dashed line box to show your Mach. Boundaries).

Got toi run------back in awhile.

Hope this Helps, Chip

General Mach Discussion / Re: Changing the Sensitivity of Limit Switches?

« on: February 07, 2008, 06:25:02 PM »

Hi, Thkoutsidthebox

The Debounce setting should help, It will delay Mach a little on responding to the switch closing.

Most use NC switch's in series, That way your system won't reset unless it confirms continuity of the switch's.

The non soldered raped connections need to be soldered, You no.

Hope this Helps, Chip

Hi, Thkoutsidthebox

"Limit switches less sensitive", Can you expand on this a little, Are thy tripping on there own ?

Thanks, Chip

Hi, Clint

In motor tuning set the Step&Dir Pulse's to 5, This will give your stepper control more time to see the Pulse's

Setting up Vel. & Accl. is a balancing Act !!, It's primarily used for Rapid Moves (G00) Your F?? set's your Cut Speed's and will override Vel./Accl.

Set the Vel. Up to a speed that it start's lousing steps then back it down by about 10%, Do the same process for the Accl.

Use a distance that will allow you to see the top Vel. and then return to a stopped condition, G00 moves.

I think your accl. may be set to low.

Have you run the Driver Test, It's located in C:\Mach3 Folder, Run it and see what it shows.

If you have large spikes in the graph you may need to clear up Windows.

Thanks, Chip

Hi, Clint

I think what maybe causing your problem is as follows,

Mach default's on start-up to F6 feed (Feedrate 6.00), If you use the Jog key's to setup Motor Tuning, Velocity & Acceleration, Thy will be way off.

On the Program Run Screen, Click on the Feed-rate DRO line, Type in 100 then "Enter", Feed-rate is now 100.00, Units/Min will show Your Velocity setting.

OK now check the % Jog setting, Press the TAB key for "Pop-out Jog Window", Set the Slow Jog Rate to 100 %.

Now set up your Velocity & Acceleration and then give your G-code a try.

Hope this Helps, Chip
