Try using R3.043.000

some pictures and the dxf file of your problem would help.

My idea is you can not change the step rate with g-code.

1.  If the error is a constant amount no matter what distance you have moved, you have backlash or a loose component.

2.  If the error changes as the distance moved changes you have step count error, the amount is proportional to the distance moved.

Backlash or a loose component is a constant error (within reason) it jerks one way and stops then the axis moves, reverse the direction and the component moves the other way then stops and the machine continues on its way.

If your error is constant then you have the first problem.

Look for loose blocks, belts, screws, anchor plates etc.

If you cut a slot that is 5" long is the error half as much?

If YES its a steps per issue

If NO then its backlash/loose component

Hi,

post your code as I am not sure what your problem is.

General Mach Discussion / Re: help with tool length offsets

« on: March 26, 2009, 02:24:19 PM »

When setting up your machine there are 2 common ways to do this.

Tool 1 is your datum tool.

Your datum tool (Tool 1) is used to touch on the Z datum face of the part, the machine is zeroed at this position and all other tools are then touched on the same point and the difference in length is then entered into the offset for that tool.

The problem with this method is that if you change tool 1 for a different tool 1 then all offsets need to be reset to the new tool.

Or

A probe or setting tool.

You use a probe (Tool 0) to touch on the Z datum face, zero out the Z axis at this point then touch each tool on the face and set every tools offset with the difference in length from the probe.

The advantage of this method is that all tools have a offset to a standard tool/probe.  If the probe is placed into a setting holder and a height gauge placed on the top and zeroed out the next tool can be put in the setter and the height recorded for that tool, this is then the offset for the machine for that tool.  This offset will not change unless the tool is moved in the holder or needs to be replaced.

OK,

turn the watchdog off in config and change the limit switch debounce to a much bigger number e.g. 2000

Try this and let us know how you get on.

Are you getting an error message ?

If it is a watchdog error then in general config you can turn the watchdog off.

Great news on the offset shift, that is going to make setting up much easier.
