General Mach Discussion / Re: A million dollars to the person that can help me.

Hi, Barry

May have a bad xml file.

Look in C:\Mach3\xmlbackups folder, It has backup xml's, Sort it by Date, Make a copy of the one that is just before the date you started having trouble.

Past it in C:\Mach3\ folder, Then re name it th Mach3Test.xml and load it, Give it a try.

With the boards your using there are a lot of special settings, It's probably the encoder interface board's settings your missing.

Thanks, Chip

Hi, Barry

Give us a list of the boards/cards your using.

Thanks, Chip

General Mach Discussion / Re: Rapid movement problem

« on: February 25, 2008, 03:08:18 AM »

Hi, Chris64

Had to go to the Airport (oil leak airplane,Work), Thanks RC, Your on the Money !!.

On the Program Run page set the feed-rate to 250.00 (This puts feed-rate well above what your Max Vel will be).

Hit the TAB key for pop-out jog window, Set the Slow Jog Rate to 100 %, Jog Mode to Cont.

Now your set to use the axis arrow key's or mouse axis dir. buttons to set vel & accl. settings, (Setting up vel/accl is a balancing act).

Set your accl to 15 and vel. to 45 for a start (Vel is typically 3 times higher than accl (more or less)).

Increase the accl up till your servo trips then back it off 10 % or so, Then set the vel up till it trips, Back it off 10% or so or till you think it's fast enough (Speed's can get scary).

If you haven't setup/calibrated your Step's Per to inch or mm, You need to do that first.

Getting Late, Then after you get the max'es set, Your slower G01 with F speeds should be fine.

Hope this Helps, Chip

Hi, Chris64

This is a problem that is common, Mach default feed-rate is set to 6, The short of it is use MDI moves G00 X20 or so if you have the room.

Then adjust your Vel & Acceleration using G00 moves or hold down Shift key and arrow key's.

This should get you started in proper tuning.

Back in A-While, Chip

Hi, Barry

You never!! responded to the help "start" hear, Starting a new Post isn't going to fix it !!

Sounds like you've lost the 5 volts to your encoders, If you haven't changed any thing, That's the first place to look.

Disconnect the pos. leads to your servo motors.

On your Gecko's, Check from Gnd to Encoder + terminal for 5 volt's, If you don't have power to the encoder's it's not going to work.

If the encoder's have power, Check the A & B encoder terminals on the Gecko's,  Gnd to A & Gnd to B for 5 volt's then 0 volt's by turning the servo shaft

slowly, If thy are both good, Swap the A, B, encoder wires around, Reconnect the pos. lead to the servo motor and re-set it, Should lock-up and hold

position. Turn the power off when connecting or disconnecting wire's.

Thanks, Chip

Hi, Steve

Yes the DRO aren't moving, When it's acting up it just doesn't load the A axis ABS moves, INC moves are fine, MDI line is sometines intermitent also.

One other thing I've noted is if you make a TAB/MPG move or MDI line move the Screen doesn't update completely, A click on the screen or additional jog move and you can see it.

Just a Bug in there Somewhere, I'd say.

Thanks, Chip

Hi, Jon

Should work fine, Printer Port/Mach3 is looking for the 0 or 5 volt's,  Over 5 volt's can damage the p/port.

« on: February 23, 2008, 08:13:38 AM »

Hi, Brian & Steve

Mach isn't reading A axis moves in g-code and MDI line from time to
time, Inc moves seem fine, ABS moves are not.

It's doing it on another computer hear also, Pic's below.

G90 (INC First)
G00 x0
g01 z -.25 f100
g91 ;inc move set
G01 x2.5 A720 f100
g90 ;abs move re-set
g00 z0
g01 z -.25 f100
G01 x5 A1440 f100
g90 ;abs move re-set
g00 z0
g00 x0
M30
%

G90 ;abs move set (INC Last)
G00 x0
g01 z -.25 f100
G01 x2.5 A1440 f100
g00 z0
g01 z -.25 f100
g91 ;inc move set
G01 x2.5 A720 f100
g90 ;abs move re-set
g00 z0
g00 x0
M30

Hi, Barry

Sounds like you've lost the 5 volts to your encoders, If you haven't changed any thing, That's the first place to look.

Disconnect the pos. leads to ro your servos or uncouple them from driving your axises.

Some servo controls will runaway without the A/B encoder feedback.

Its smiler to having the polarity backwards on a servomotor in relationship to the encoder feedback, The more the motor/encoder turns the more the feedback/error it gets and the faster the motor turns, But in this case the encoder count limit will usually trip the servo control.

Hope this Helps, Chip

G-Code, CAD, and CAM discussions / Re: M99, M98 problems...

« on: February 21, 2008, 10:30:11 PM »

Hi, Chris

The M98 & M99 work together M98 (Subfile 1.tap) L10 ,(Calls (Subfile 1.tap), The M99 returns it to M98 till the L10 repeats 10 times then M30 end's it and return to top of the code


G28.1 Z0 Y0 X0
M98 (Subfile 1.tap) L10 (Calls (Subfile.tap) 10 times
M30

The following is in a .tap file called Subfile 1.tap located in c:\mach3\Subroutines\ and is repeated 10 times

G0 G49 G40 G17 G50 G90
G82 X0 Y0 Z-.01 P0 R-.001 F150
X1.53 Y3.1 Z-.42
M99 (Without the M99 the file wouldn't repeat and Just end.)

Hope this Helps, Chip
