The autoleveller no work in my machine CNC 3040 USB

[ThulsaDoom]

Hi, this is my first post, I am Spanish, I apologize to my poor English.

I have a cnc milling machine 3040 USB.

The software autoleveller doesn't work fine in my machine, when start the test gives me a warning of "softlimit warning... continue?", if I skip that warning makes the test but does it in an irregular way.
When the test is finished and the button is pressed for the so that it starts to work, the z-axis is never 0, always with positive values.

If I use my gcode of work without autoleveller, the machine works perfectly

If you need videos or photos of the screen tell me and upload them.

Thanks

ThulsaDoom,
My first question would be, What controller are you using??? Mach3 or ?????
This can be helpful in trying to diagnose any problems.

Next, Did you "Home" the machine prior to running AutoLeveler????

Did you use the proper machine type in the drop down menu?????

I also assume your using the correct units of measurement??? mm

Hi, I'm sorry by the delay, I go to the answer the questions

My first question would be, What controller are you using??? Mach3 or ?????

I use Mach3, this is the interface

Next, Did you "Home" the machine prior to running AutoLeveler????

Ok, I put one an image of how I have configured the machine dimestions


There are two home in the software, the home of the machine (ref all home) and the home of the part.
Ref all home I placed it in the left front and the z axis in the bottom.

When I start the test I place the machine in the home of the piece

Did you use the proper machine type in the drop down menu?????

I don't know what menu you mean

This is my machine

I also assume your using the correct units of measurement??? mm

Yes. I use mm

If you want, I can make a video of the operation and upload the link

Looks like you should be doing things properly.
What I was refering to is the drop down menu as shown below:

Then we will have to take it one step at a time to try and figure out what is going wrong.

Hi, thanks foy your help

Okay, I'll show you step by step how I do it

Fris: I load my Gcode in the software Autoleveller.
Second: I select in the menu, mach3 and I leave the options by defect
Third: I save the result in the new file in my PC by clicling in the button "Create Levelled GCode"

An image of the software


I put one link with two files, a file is my test GCode origininal and second file is a GCode modifioqued by Autoleveller

ThulsaDoom,
Thanks for all the supporting information. I "think" if may have found the problem and is has to do with your limits setup in Mach3. (For the record, I don't use Mach3 so I may be way offbase)

If you look at line 21 in the AL_PCB_Priebas CNC3040.GBL.nc, you will see:

G31 Z-10 F100

This is exactly proper as normal homing of the Z axis of a mill is with the spindle (quill) at the extreme upper allowable movement in machine coordinates (G53), therefore ALL movements are in a negative direction from that point. When you do your offsets for your work piece (G54) you typically set the TOP of the work piece as Z0 and once again all movements for cutting of the piece are in the negative direction.

Therefore, I feel in your setup page of limits, your MAX Z would be "0" and the MIN Z would be "-50". I believe these settings are in Machine Coordinate values (G53) and Mach automatically runs programs in G54 offset values. So now you need to be sure you have a minimum of
20mm above the height of your stock or you will have to change "Safe Z Height" in AutoLeveler to an appropriate value.

Hope this helps.

Hi, I've tried what you tell me but it does not work, I upload a video like work the machin whit Gcode+autoleveller, and I upload you an image of how I configured the limits of the machine.

As you see in the video, the performance is not stable, it loses steps,

With gcode without autoleveller the machine working properly

ThulsaDoom,
OK, again, I am picking at straws, but I know of nothing in AutoLeveler that will by itself cause loss of steps.

The probing gcode file uses G0 to go between the various probing locations and I did notice in the video especially on the first pass across the board some irregularity in the motion. If it was my machine, first off, I would check to be sure all axis move freely and have no binding at any point. Secondly, I would check my setup particularly the acceleration factors for the steppers and then possibly the max velocity for each of them.
I found a similar problem on my own machine and had to back off somewhat for each of these factors or the machine would stall and loose steps.

That's the best I can do for you at this point, hopefully somebody else might jump in and give you some advice.

Hi, if I use only the gcode of my project the machine works perfectly, that's what confuses me.
In autoleveller software I can't set the speed, but the movement is not normal, can anyone help me?.

thanks for your help

ThulsaDoom
While doing some additional looking, I noticed your using Autoleveler V 0.7.7 and you are correct in that it will not allow you to set the probing speed.
However, the latest AE version (Member Download) does have that option.

Just some food for thought.
