Hi Adam,

Do you have to have Absolute or Incremental selected for IJ mode in General Config. to get rid of the crop circles ??

There is a lot of 'trial and error' required to get each axis Velocity and Acceleration to their optimum values.

This is what I would do...

Just one axis at a time - increase Vecocity until the axis stalls on fast jog (shift + arrow key) reduce velocity by 30% and save changes. Do a similar thing with Acceleration.

Hi Frank,

Towards the beginning of your Gcode there should be an F*********x command (eg. F600) change this (and any other repeats of the F*********x command) to a higher value and save the changes. Check that you specify a high enough feed-rate in the CAD/CAM software that you use to create the Gcode.

If your spindle only has an 1/8" chuck then, unfortunately, you are limited to the available cutters that you can use. Also your spindle motor may not have sufficient horsepower to drive a larger diameter cutter.

Check out ebay for "V groove cutter" there should be lots to choose from, including different angles (not 1/8" shaft though).

I don't think you will be wasting your time posting anywhere on this forum.

Hi Adam,

Sorry, my fault, I did not explain it very well.

If your CAD/CAM software is always going to create arcs using Absolute IJ Mode then mod. the post processor you are using to create the Gcode to include G90.1 at the start of the code (if it uses Incremental then G91.1 at the start of the code). This will save you having to make future changes to the IJ mode manually.

Hi Adam,

Ahh. looks like the dreaded crop circles.

Config. / General Config. change the IJ Mode (located centre of screen) then regen. toolpath.

Perhaps mod you post processor to include the correct G90.1 / G91.1 (at the start of the Gcode) to avoid this in the future.
