Thread: Y axis problem

Hi there, I have a problem with the Y axis on my 6040 machine, i'm machining a square as a test and each time the gantry moves to the Y it's out of position be 0.3302mm and this accumulates each time.
Can anyone shed some light on what the problem could be ?

Are you using mach3? If yes you, can calibrate your axis thru mach3 program.

Yes i am using mach3 and have calibrated the axis over 300mm of travel, it repeats pretty much bang on

I am one of those people that does not believe in using Mach3 calibration - if you can't calculate the settings and get it right, then you might be covering up a more serious problem. But I'm probably in a minority here...
Back to the original problem - can you describe a bit more exactly what you are doing? Given that you are quoting dimensions to .0001mm, I'm guessing that you are taking these figures from the Mach3 DRO?

No, it's the conversion from an imperial dti that's all

How many steps does that distance work out as?

To be perfectly honest I have no idea, is there a way to work that out

What's your step/unit setting?
And are you using metric or imperial?Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

I'm using metric and the step per rev is set to 320 the same as the X axis

I should just add the velocity is set to 1500 and the acceleration 400
Both step Pulse and step direct are set to 5
