General Mach Discussion / Re: How fast??

« on: September 09, 2006, 05:42:26 PM »

Hi, Swets

You need to set the acceleration down to a value much lower try 10  ( This is the start speed ).

The Velocity is the max speed, If the steppers slip at 1000 then set it down to 900.

You may need to set the Step, Dir Pulse's Up to 4 or 5 to start with (the range is 0 - 5 This is the time Mach pulse is on to give your driver

time to See the step or direction change.

What is the speed of the computer you are useing

Hope this Helps, Chip

Hi, guynamedbathgate

May be Config, General Logic,  bottom center, Auto Screen Enlarge, un check it, OK, then restart Mach.

Or is this a Windows screen problem,. Start, Control Panel, Display, Settings, screen resoluation, move bar, Apply, OK.

Second again ------------------so sad

Hope this Helps, Chip

Hi, clachan

Your missing a Enter after your M99 in your code or you can use a % after the last line.

F1000
g90
G00 x20 y20
g00 x0 y0
m98 p1234 l50
m30

o1234
g01 x20
y20
x-20
y-20
z-20
x20
y20
x-20
y-20
z20
x0
y0
z0
m99
%

It's been repeating for me now, It's easy to leave a Enter/Blank line Below your M99 out of your Gcode.

Hope this Helps, Chip

Hi, Chris

Glad you got it working.

Thank's Chip

General Mach Discussion / Re: how do i change cw/ccw from a motor in mach 3 ??

« on: September 08, 2006, 02:54:28 PM »

Hi, Swets

Turn the Power Off before changeing wires.

This is for Bipolar 4 Wire Steppers only, You need to change two wires that go to one coil in the stepper motor.

If your using Geco stepper drives, Thay have Phase A, B, C, D,  swap the Phase A and Phase B wires around on your Y axis, then uncheck the rev. in Home Limits.

If your using other Bipolar drive it should have A+,  A-,  B+, B-, Swap the A+ A- wires around then uncheck the rev. in Home Limits.

For 5, 6 ,8 Wire steppers Unipolar

Thay usually have terminal marking's 1, 2, 3, 4, or A, B, C, D,  mark the wires then remove them, reinstall them in rev. order 4,3,2,1 or

D,C.B,A this will change the direction, then uncheck the rev. in Home Limits.The DC power + or -. 5th wire to the stepper motor should

not be changed.

This will allow you to use your Default Settings in Mach.

Hope this Helps, Chip

Hi, Cory

What ver of Mach are you using, post your dxf file

What post processor are you using.

Hi, Brian

Enjoy your trip, I have looked at this some more, If I use the Keep Layer info. option as it is, it posts code OK except for needing to swap the

G41, G42, The other Load Options seem to have some problems with the G41,42, as you stated it needs a thorough look through.

Thank's, Chip

Hi, Chris

At this point you should swap the servo motors around or at least check the ohm's value between the + - motor leads with them disconnected from the control may be bad motor or brushes is it oily to.

The reason the drives are slow is the 1000 count encoder this gives you .00005 per Mach step.

If you use a 500 count encoder it will give you .0001 per Mach step and pickup allot of speed.

If your encoders are remotely mounted not mounted  on the motor, any backlash between them can cause problems.

You didn't state the values your using on the Y axis ?

Just some more input, Chip

Hi, Chris

Have you compaired the X Y torque with the servos off ?

Have you turned up the Gain and Dampening on the Y axis, till the force to move it is the same as the X.

Is there any slop if you hold the encoder and turn the servo back and forth.

Encoders work better if thay are on the motor direct, If your encoders are 1000 count encoders thats 4000 steps per turn, 5 turns per inch, it wouldn't take much slop  between encoder and motor to fault the drive.

In Config Motor Tuning what are the settings for both X Y,  Step's Per______Velocity______ Acceleration______ Stp., Dir. Pulse

Hope this Helps, Chip

Hi, wvancura

Dose your DXF have 5 layer's with the item's on each layer that you want, are you checking the Keep Layer info as is top check box in Load Options.

The Ignore layer info will just create an inside and outside layer.

Using Layer Control you can set the Cut Order and by clicking on item's you can change the cut order on each layer to some degree.

Press center mouse wheel for Pan moving mouse.

Shift and left mouse button for Zoom moving mouse.

Cntl and left mouse button for moving window around with mouse

You can only change or move leadins with a strait on view double click screen for default view.

Hope this not too much or to little.

Thank's Chip
