I did go to store bought coupler because the rubber tube started slipping, what I bought.

I have just changed the stepper motor drive ( X an Y ) from direct drive to gearing, it now has the stepper turning 1 time to the screw turning 4 times. I now have a IPM of 250 when it start lossing steps. ( I figure the stepper motor is doing about 812 RPM). Used a 16 tooth 32 Pitch Shaft Mount Pinion Gear and 64 tooth 32 Pitch Shaft Mount gear

Got them from Servocity

I doubt I will be able to run faster then 100 IPM as the machine is starting to jump around as it start and stops. I guess that what happen when the machine get rigid. I am not sure I can make it any more rigid using wood.

Machine accuracy? It mite be .015 now, it is getting harder to improve, each mod has improved it but I now know more, how to look at accuracy. I think this is all the accuracy I need for what I do.

Ok Parts.
Still using the same steppers, drivers, power supply and Mach3. ( I am thinking of a new power supply that will run at 48V as the drives that I have will handle it.) I would run the Z off the old power supply and X and Y off the new supply.
I am now using Fusion 360 for CAD and CAM and NC Corrector v4.0 to view G-code, ( I know fusion will do this )
I have not had a need for Inkscape but I could see a need later for it.
