General Mach Discussion / Re: Homing Problem - Slave Axis

« on: January 31, 2009, 01:31:55 PM »

Hi, Joepardy

I used X, C axises to save the A for rotary use later if needed, Yes if you have one axis reversed you'll need to change the wiring.

Stepper 4 wire type, Swap the A, A- wires around on the motor, On stepper 5 wire type, Reverse the 4 wires on motors 1, 2, 3, 4, to 4, 3, 2, 1.

Servo's, Swap the motor + - wires around and swap the A & B encoders outputs.

Hi, Joepardy

Are you using the "Reversed" settings on you X or A axis.

Looked back at the xml used on the gantry water-jet cutter, We used X and C axises with no "Reversed" on ether axis in Homes & Limits and DoButton( 22 ).

Hi, Joepardy

Try this in your "Ref All Home" Button's, I had similar Issues with a X, A, dual Axis system awhile back.

DoButton( 24 ) 'Z Home Axis
RefCombination( 9 ) 'X + A Home
DoButton( 23 ) 'Y Home Axis

Hear's some info to review from some Post's.

Art also wrote this... and I found the complete "Refcombination" listing here....

"Art wrote....   The home switches, (which may be set to the same input as the limit
switches), are used only for homing. The axis will move to the switch, then
slowly move off.

   The program by default does one at a time, because thats the most usual
combination. YOu CAN move any combination at once by editing the RefAll
buttons script. There is a command called RefCombination( n ) which will ref
any combination of the axi s. N is calcuated by adding the following
numbers..

X - 1
Y - 2
Z - 4
A - 8
B - 16
C - 32

Ref X and Y together would be RefCombination( 3 )

Hope this Helps, Chip

Hi, Odinson

Sounds like your Ports & Pins settings are set incorrect, In Motor Outputs re-check your Pin setting's.

1. Direction & Step "Low-Active's", Should be ALL be the Same, Ether All ("Check" or All "X") ed. (Only exception is if your using different type's of driver board's).

If any Axis Run's Backwards, Use, Configure, Home & Limit's, "Reversed", ("Check" or "X") ed., To resolve this.

Just a start, Chip

Hi, Wayne

Your gantry is twisting. It can be allot of issues, Steps Per settings different on one side, Homing issues, Home  SW's settings issues, Lost step's on one side, ...........

Hi, Art, Willem

That fixed it up, All tool's seem to load now, Her's 3 dxf's all the same except for left side shape termination, one good two are bad.

I see you cant rotate the cutter insert's now, In time will get it back when you get the final pass worked out, I'm guessing.

Willem, With the large Units your using, There's allot of calculations going on with small cuts per pass values are used, When proofing the profile try using a larger per pass value, It speeds it up allot.

Thanks, Chip
