G-Code, CAD, and CAM discussions / Re: Mach3 G-CODE Size/Scale problem

« on: May 02, 2007, 05:07:33 PM »

Useless is not in the Mach vocab, I bet you learned to drive in 20 minutes too, 

Steps per is what you need to set.

Open the motor tuning page and click X axis

In the steps per you should have 4000 set if your xylotex driver card is set to full step.

If its set to half step then the steps per should be 8000

If its set to quarter step then steps per should be 16000

Set velocity to around 60 and Acceleration to 1 you must then click 'save axis settings' then try the axis.

If it moves set Y and Z the same.

Check the amount the axis is moving against what you have asked it to move.

If all is well then you can play around with the velocity and acceleration to get the optimum from your drives.

General Mach Discussion / Re: "SmartPath" or Waterjet Speed ramping based on geometry question??

There is no set function for doing this, but it can be done with the accel/decel, by setting this to ramp up and down at a slow rate it is possible.

General Mach Discussion / Re: Macro Pump

« on: May 02, 2007, 12:11:56 PM »

The macro pump is a list of VB commands stored in a file called MacroPump.m1s in the current profile.

Any valid VB script can be used.  The macropump runs about 40 times a second continually.  it must be enable in general config first and mach re-run to start the process.

What are you tring to do?. it may have been done already.

There is some info here :- http://www.artsoftcontrols.com/MachCustomizeWiki/index.php?search=macropump&go=Go

The code should do the same job as your code, the idea was that if the same problem was found then the machine is at fault not the code, if the new code worked ok then it is a lcam fault.

To convert a negative number to positive in VB use ABS(n)

e.g. A=Abs(-123.456)

A=123.456

you can also do this

CODE "G92 Y" & ABS(GetDRO(84)) ' read machine Y dro

General Mach Discussion / Re: Backlash compensation causes non constant feed

« on: April 28, 2007, 01:44:46 AM »

Going by your plot,

it looks to me that you have too much compensation set, if you are getting a straight line at the quadrant points the axis compensation is moving the table not taking up the backlash, reduce the amount of compensation and try again.
