Hi Roxy,
I am slightly confused, I firstly set my probe on the Z min pin which worked or appeared to but when I tried to home Z the machine went through the homing routine but when the home position was reached i.e. X0.00 Y0.00 Z0.00 the Z axis raised to approx 10mm above the bed. So I refitted the Z micro switch to Z min pin and connected the probe to Z max pin resulting in perfect homing though when bed levelling was run the probe never reached the trigger point before the zero micro switch activated so as I said I am confused so I again removed the micro switch and reverted to probe on Z min pin and sure the levelling routine works fine and so does the homing routine but I cannot get the nozel to stay at Z 0.00 as soon as Z 0.00 is reached Z raises to +6.8 mm from the bed. I have tried to find setting in configuration.h file to adjust it but what ever I have tried I don't seem to be able to find the answer, can you please help or is this normal. Having G28 set Z0.00 then raising to +6.8 mm, when printing starts does the printer drop to the first layer height 0.2 mm.
I might say this is my third and latest home built i3 printer, I am trying to go one step further with auto levelling and colour mixing which seems a large leap forward but it keeps me busy and learning in my retirement.
