General Mach Discussion / problems with machining holes and Z axis
« on: October 08, 2017, 03:20:39 PM »
Hello all.
i'm trying to make a few bits for my motorbike and am experiencing some problems.
When the Z axis is set to zero/home and then i start the gcode, it's not calibrating prooperly, yet when i do the auoto caliberation it is perfect.
i have the units set to 400 per, yet it only moves decimals of a millimeter, if i set it to 800 it moves 2mm (which is correct as i'm trying to move it 1mm at a time), i then change it to 405 and its moving 0.9mm....if i switch the computer off and return to it it starts all over again despite keeping the 405 setting.
Also, my holes i'm trying to machine out of the centre are offset, even though they are drawn central.....they're South West by approximately 3mm.
Any help greatly appreciated.
Thank you
