Hi all,
I've got the latest PRO 4896 all setup and running now, only thing is i've lost half a head of hair trying to make this thing accurate !
I don't know whether im asking to much from it or not but I am having a hell of time trying to true it up. Going from Inches to MM as well.
Methods I've tried are a dial indicator, attached to a solid section and using the mach3 Cal program. Got close to repeatable, but was still .3mm off at times. Which seems like a lot !
Next I lashed out and purchased a set of gauge blocks to get a better distance up to calibrate it to and a mitutoyo test indicator. Works alright, able to get it within 0.01 with this method. I was calibrating it to 90mm with a couple of blocks together.
The real issue im having is over the space of the entire machine the error of calibration gets multiplied, so calibrating it to 90mm as I have, if i have an error of 0.001mm, over 2420mm i've all of a sudden got an error of 2.420mm, which is about what im getting ! So confusing, I don't know what Im doing wrong...
I've tried cutting a 90x90mm square using a small 2mm deep profile cut on laminate MDF, funny enough I was getting 89.78mmx89.78mm, which tells me my bit may not be exactly 6mm (Is what I set tool compensation to ) as that is what the packet said it was ( Measured 5.88mm on the venier, but compensating for that in CAM would make the square even smaller !).
In summary, am I asking to much ? Is my method of calibration not correct ?? The error I am most worried about is the fact that a 0.001mm error down one end equals a 2.5mm error down the other.
Does imputing a strange value into mach3's steps per cause issues ? eg. 68.3432342134
Using a Huanyang 2.2kw spindle, Moore& Wright dial ind. , Mitutoyo test (dog leg) ind. , measuremax gauge blocks.
Any suggestions, I'm really struggling here !
