Hi, Inivator

On Settings page use, Auto Limit Over-Ride or Manual Limit Over-Ride (Reset Button) Jog off the limit.

Many are using Screen Hunter Free  http://www.wisdom-soft.com/sh/index.htm

General Mach Discussion / Re: homing my rotational axis

Hi, Scott

Would you post the code for your homing routine or an example of one liner axis with the "homing condition logic".

My Oxygen to Carbon Dioxide ratios get All out of whack with VB learning curve hear.

Mastered the others long-time-ago.

Thanks, Chip

Hi, TMSmith

Mach displays offsets properly on the "view screen" when loaded and with Regen Tool-path.

But it doesn't (dose not) display it properly on the "view screen" when Running the code (cycle start).

Your mill will cut the part correct, It's a Bug in the view screen code (offset issue).

Brian is re-writing the View Screen code, So at some point it should display it correct.

Hi, Shawn

This is probably the Max CL Mode diag. (Mill)

PIN ASSIGNMENTS FOR THE
MAXNC CL2 SOFTWARE

PRINTER PORT PIN ASSIGNMENT

1............... M3 OUTPUT (LOW=ON, PULSE FOR PWM)
2............... A AXIS (quadrature)
3............... A AXIS (quadrature)
4............... Y AXIS (quadrature)
5............... Y AXIS (quadrature)
6................X AXIS (quadrature)
7............... X AXIS (quadrature)
8............... Z AXIS (quadrature)
9............... Z AXIS (quadrature)
10.............. INPUT, MOVE ENABLE (LOW=NORMAL OPERATION, HIGH=STOP, SEE NOTE)
11.............. INACTIVE
12.............. INPUT, HOME SWITCH (NORMAL OPERATION LOW)
13.............. INPUT, G61 SWITCH SENSOR
14.............. M8 OUTPUT (LOW=ON)
15.............. NONE
16.............. OUTPUT, DISABLE POWER TO MOTORS (LOW=NORMAL, HIGH=DISABLE)
17.............. OUTPUT, RESET CONTROLLER (LOW=RESET, HIGH=NORMAL)
18.............. ALL SIGNALS GROUND
19 TO 25 ....... NONE


NOTE: MOVE ENABLE IS USED TO STOP THE COMPUTER STREAM OF CODES UNTIL THE SERVO
MOTORS CATCH UP. ON TIME-OUT IT WILL PRODUCE A SERVO ERROR.

Hi, Ryan

I've never had that happen, When updating Mach I just install it on top of the previous version most of the time.

Have you removed Mach with windows remove commands before installing new versions.

Thanks, Chip

General Mach Discussion / Re: synchronize flow rates and motor speed
« on: June 20, 2008, 08:56:30 PM »
Hi, George

From what I see in the link you posted, This pump is driven by a stepper motor.

A little rambling hear:

Setup Mach in CV mode and set a feed-rate that will allow the blended speed to be constant.

Set up your stepper pump control to turn on and off with M3, M5 (spindle ON, OFF), Or Coolant ON, OFF.

Stepper Pump Control, It appears that if the pump is driven at a constant speed it delivers a constant flow.

May need an ON OFF valve also depending on the viscosity of your fluid (cont with same ON OFF.

Use a 555 timer to set an Adjustable pulse rate to Calibrate your Stepper Pump Control, Pulses to "step input" (direction needs to be held to Hi or Low for proper pump direction). There are many ways to set pulse rate.

I think trying to integrate the pump as an Axis has allot of issues, The biggest being that all axises are Blended and fed to the printer port for execution.

Maybe using the Step/Dir Spindle feature could work, Haven't fooled with it hear much.

Hope this Helps, Chip

Hi, Cosha

I checked there web site, Not much info there, Sad to say.

It should be an enable pin or jumper in you paperwork.

Change the state Active Low

General Mach Discussion / Re: Z Axis Issue
« on: June 20, 2008, 02:58:13 PM »
Hi, Michael

Post your G-code file, If the second  cir. Z depth is correct, Is the Z depth in the first one correct in your G-code.

Double check your VCarve drawing depth settings, If it was a Mach/Z axis error the second one should have the same error.

Thanks, Chip

Hi, Shawn

Your last comment is probably correct, "MaxNC sell a program called Max III that looks identical to mach3. I am not sure if it is just re-branded or has a special version of Mach3 been build for them with drivers that support this configuration".

Hi, Ryan

Do you have a Mach3 Lic. also (500 line limit without), Your g-code looks fine hear.

Look under Help, About, In Mach to see if it Installed.
