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.

Did you zero your Z on the top of the part? You can see in his code:
G0 X0.0 Y0.0
G0 Z1.0
G1 F300.0 Z-0.4
G1 F800.0 X40.0
G1 Y40.0
G1 X0.0

That the Z will move to 1mm above the part and then sets the feed rate to 300mm/min and drops the Z to -0.4mm below the top of the part.

What do you mean by (just hovers) ie does it stay still or does it follow the intended path?

Yes I zeroed the top.

The z seems to move up the further it gets into the job.

This is on some scrap pcb board. https://uploads.tapatalk-cdn.com/201...a6d16139bb.jpg

Or the bed is going down. Have you levelled the bed and skimmed the top off?

Hi, if you go to my blog it gives all the mach3 settings. It sounds like some of the settings are ok and some aren’t, so just spend a bit of time going through them. If you’re still unsure pm me and I’ll go through them with you

Yes. My controller is very basic and doesn't have spindle mach3 spindle control
