So I was doing a test on the onefinity to cut a 0.5" aluminium block out 6061-T6. I got it cut out and the block measures 0.5110" on one side and .5110" on the other side. I have a 123 block that I measured to check the caliper (mitutoyo) accuracy and it measured 1.0005. Any suggestions on why th…

Did you mean to write the accuracy as to within .01" ?

Yes I did. Thanks I corrected with a edit.

could it be the diameter of the end mill off by a frog hair?

What were you feeds & speeds and bit size? If you push the bit to hard I find a bit of deflection happens which could account for your increased even sizing. Bit is turning clockwise so the extra would always be on the outside of the piece. & DOC as well -Alex

Is this an unusual result for your set up? I have a different controller, and needed to use the axis calibration feature to dial in the accuracy during my testing of the 1F. I do not have a precision scale, but using various measuring devices found it was off about 1mm over 800mm initially. After th…

Is it standard practice to calibrate steps per mm for cnc machines?

I am new to CNC work, but when setting up my 1F using my Masso G3 controller i was happy to have great repeatability of motion and position. It made me wonder however if when I tell it to move 750mm along the x axis, for example, it was actually moving that distance. That is when I calibrated it ha…

@buggman Thanks for the response. I was out of town for the weekend. I did mesure the bit and it was a bit under. I put brand new bit in that was 0.25" and ran two test cuts and they both came out exactly 0.50" Thanks for the tip. I usually only do wood and this aluminium thing is new to me so…

@MikeH , @cyberreefguru . Thanks for the link post and the procedure for the calibaration. Seems like it was bit diameter was a bit under due to wear. But I will be doing the cybereefguru calibaration.
