mach3 mill

Thank you for your reply. I had another half hour this morning and made some dial measurements. The back lash in the new H screw is 0.08mm and in the Y screw 0.05mm.

In order to finish the miller off, I need a plate to mount the Z drive and this plate has a hole of 32 mm . So I thought I would use the Hole Wizard. Having set units to mm and entered the data for X and Y centres plus hole diamter, I did a test run.

No good, circle was far too big-- recheck data still too big. Change diamter data and re-run but the same size appears. The X and Y centres are spot on, the no mater what diameter I enter into the wizard (and save) the G code always describes the big circle. I realise that the wizards are not supported, so need to ask if there is a known problem? or is it me?. many thanks // Joe

Ohms law states that the current through a conductor between two points is directly proportional to the potential difference (PD) or voltage across the two points, and inversely proportional to the resistance between them .

Hi All, forget the last post re circle cutter, a PC restart and it now does what it says on the tin.
