General Mach Discussion / Increase axis drive speed

« on: July 19, 2020, 09:27:35 AM »

Hi

I haven't posted on the forum for a while due to illness but I would like some help please.

I have added an intermediate pulley to my X axis and re-calibrated the drive so the distance moved is correct  but now the axis is moving too slowly and I can't speed it up as the drive settings are at their maximum so I am not sure how to speed up the axis further.

Any help much appreciated.

I think you're problem is better solved using a 3d cad program to construct the surface and then a CAM programme to generate the gcode

.

A easier way would be to use the calculator, get the points, put into 2d CAD and it have it drawn.
Even that  requires some level of experience.

CamBam can do it all and there is info in the manual on how it's done.

A number of ways, but, my thoughts are what is free and needs the least amount of know how to do.

No disrespect Rich but is it not better offer advice without out disrespecting someone else's, freely given advice?

Does not dish mean 3D?

Hi Michae

I think you're problem is better solved using a 3d cad program to construct the surface and then a CAM programme to generate the gcode.
In your 3d cad programme you will need to generate a parabola and then rotate it to form the surface (parabolic dish).
In order to generate the parabolic line you will need to look up the formula that describes it, y=x^2
You should be able to generate the points required using chosen values of y.

I hope this helps

As far as I know a dxf file is just a text file so open it in notepad and see if you can read it.

I hope this helps Brian

Can you import it into a CAD programme and trace around it?

Nice bit or restoration. R27 ??

Tweakie.

The R27 is very similar but this is a 1958 R26.

It should look like this when it is finished.

Excellent work my friend - are you going to be making some more for the other Welsh BMW riders ?

Tweakie.

Hi Tweakie

It was just a test really to see if my mill would cope fine work and to get the feel of using CamBam. This one is for the BMW R26 I am restoring. I have done another, slightly different one for a friend of mine.

I have got a number of designs I am hoping to make and sell.
