After your detailed explanation, they all make sense.

Thank you so much

From the attached image, there are a few columns which are not explained properly:

Reversed: this means that the axis travel is reversed? But why I want to have this axis reversed? In the tutorial (home limits & offsets) he only has the X axis reversed.

Soft Max & Soft Min: I understand the soft max is the max travel of the axis but why the soft min is 0?

Home Off. Is this Home Off or Home Offset? If it is Home Off, why I want to have it Off?

Home Neg: What is the meaning of this? How the Home position can be negative?

At the bottom left of this window there is “G28 home location coordinates” What is the meaning / purpose of this?

 

Thank you
Nicolas

Ahhh, you got to load the roadrunner to get the display going, now it works fine, thanks a lot

Looking at the other post you suggested, that is another issue I have which I could not figure out; how to zoom.

My laptop does not have a mouse wheel; can I zoom without a mouse wheel?

Where is the VB file to add the code DoOemButton(160)?

Thank you
Nicolas

You probably understood but above I said atalling, meant stalling but just got in after a long drive (for me, I hate driving) so thats my excuse

Hood

No problem Hood, I understood stalling anyway. I don't hate driving but prefer to play with my CNC instead LOL

I watched the video “Home Limits & Offsets.swf” and at the top right in the Program Run window screen (Tool:0    Table Display) I could see the outline of the table and the co ordinates moving when he was jogging the motors.

I have set the soft limits in my machine but I can’t see the table outline on that window.

Do you know what I’m doing wrong?

That is the motor atalling, you need to reduce the velocity a bit and see if that helps. Maybe the accell needs dropped a bit as well but try with the Velocity first.
Hood

I will give it a try, thank you

I’m only working with 2 driver boards right now so today I switched the boards to have the Y & X axis running for adjustments.

I have the steps set at 2000, and the kernel speed at 25000Hz.

The X axis (with an approx. travel of 22”) is running real nice at 80”velocity and 9” acceleration

However after a lot of tries I got the Y axis (with an approx. 34” travel) half working at 85” velocity and 6” acceleration. When I press the keyboard arrow keys the axis moves nicely for about 4” to 6” and then the motor whines and I lift my finger from the keyboard because I don’t want to force the motor. Now if I press the same arrow button again it reverses direction and again goes about 4” to 6” and I stop it again for the same reason.

This does not happen at the same spot because by playing around I have been able to move the gantry from one end to the other although is steps of 4” to 6” at a time.

The Y axis does not bind anywhere because I used my screwdriver as a motor and she runs nice and smooth from one end to the other.

What it means when the motor whines? Not enough torque? Too much torque? Any ideas?

Nicolas,
Not that i know of. The code is basicaly the same as the NIST - RS274NGC. Try an internat search.
RICH

I thought you were offline for the weekend RICH and so I asked HOOD in the general mach3 section. He told me the file name is mack3millgcode.htm, 22 pages and I printed, nice weekend reading LOL

Thank you for trying to help

Oh meant to say you will find it in the Mach3 folder, double clicking should automatically open it in a browser. It is called Mach3MillGcode.htm
Hood

Excellent Hood, you made my day.

I looked in the mach3 folder but was looking for gcode something file. Now I got it and it is only 22 pages, nice weekend reading

In comparison to mach3mill.pdf and mach3install.pdf (157 / 106 pages each) which I printed before, this one is a piece of cake

Thanks so much
Nicolas
