### Re: Calculate steps

Finally found the time to investigate this. A big probem as I see it is that if you mill MDF without a dust collector the dust will settle on the makerslide and clogg up the delrin wheels and make the movment uneaven. I also found that there are some bungee in the belts that came with the shapeoko 1...

### Re: Calculate steps

I used to try with 20mm, but the same error then... You said something about backlash, this might be right, do you know what part that I need to fix to remove backlash?

### Re: Calculate steps

I just can't seem to get this to work... With the 54,6806... when it is suppose to move 10mm it moves 9,5, I then use the auto calibrating tool, ask it to move 10mm, and I punch in that it moved 9,5. I then try again, and it is still off... So I belive something I do or have is wrong... I counted, I...

### Re: Calculate steps

Then with shapeoko 1 with G540;

X and Y axis is 54,68066491688539
and Z axis (with m8 rod) is 1600

Just if anybody else need this information

Ill check the Z axis, it's probably right

Thank you

### Re: Calculate steps

Aah, no I did not. I checked the wiki and since I have a stock shapeoko 1 i made the stupid mistake to assume I had those pulleys... Then will; 10 * 200 * 1/18 * 1/2 = 55,555 be right? I am also getting wrong values at the Z axis, in the wiki it sais it supposed to be 320 steps/mm but with the 10mic...

### Re: Calculate steps

Hello, cvoinescu; In the shapeoko wiki it tells me that GRBL is 8 microsteps, and adds up to 40 steps/mm, and I Googled that G540 uses 10 microsteps so I changed the 8 to a 10 and calculated again and it gave me 50 steps/mm This value I punched into Mach3. I used the auto calibratin and that gave me...

### Calculate steps

Hello

I am using Gecko g540 with mach3 to run my shapeoko, but have not calbrated it yet. I understood that the G540 had 10 microsteps so when i enter 50 in the motor tuning and asks it to move 20mm it stops at about 16,xxx.. Is there something I am missing?

Take a pill box; if you have 4th axis you can make the external threads with just rotate the box and use a V-bit, but the lid would be another problem, but with the bit Woodworker linked to, I am guessing that would not be a problem with 3 axis, just clamp the lid down, and rotate downwards and cut ...

### Re: Steps per revolution Gecko G540

Is this in the Wiki?

If you have a 100% stock shapeoko machine with a stock G540 should mach3 be set to 2000 on X and Y? What have you guys set your M8 Z axis?
