I had a similar problem with my 6040 router.The CNC Blog

Improvement with your mach3 settings. Not perfect but that may be the cutter i am using.

You are not helping yourself. why don't you copy and paste Doddy code and give some feedback as to what is happening and take it one step at a time. You have to establish if you are losing steps or have backlash etc.

How am i not helping myself. I ran his code but i still had issues so that.

Once i changed the acceleration the circle cut improved. it was set to 2000 but reducing it to 1500 improved the circle.

I'm going to run the cut again with the appropriate end mill.

Because you are not actually giving any good info ie. (it was set to 2000 but reducing it to 1500 improved the circle. ) does not mean anything with the parameters that go with it.

Also you said that you ran his code!! which code Doddy's is the only code I see in this thread and that has a square and circle.

If you want help you have be more specific with the questions as the crystal ball is broken.

im not sure what info i can give.

I'm pretty new to cnc and i posted on here for help not criticism.

i did say the acceleration was 2000 but now i set it to 1500 which has improved it. What i meant was i changed velocity.

I am sorry you feel like that but I suggest you re read this thread from the beginning and look back at your answers carefully and you will see that you have not given any clear reports back.

Did you run Doddy's code !! if so what is the result?

I ran his code but the bit just hovers above the stock so I'm not sure if it's my machine or if the gcode has been setup to zero from the bottom of the material. I'll try and get a short video showing this.

Sorry for the delay on this i ended up go away for a few days for work.

I changed my mach3 settings to the same as Kevs and it machined fine this time round.
