@Phaedrux Yes i realized what i had done late as i posted it and removed the H2 on the G1 move you will have to bear with me this is my first attempt @ setting up a 3D printer.

@jay_s_uk
Yes everything is in the correct order triple checked this including M671 and probe points.

@fcwilt you are correct the lead screw points are outside the bed area however the probe points are the position where the bed mount attaches to the bed unless you know of a way to put an offset in for the actual positions ?

@gloomyandy your description fits my bed setup.

@CaLviNx just reading through your config should the M671 command come after M584 not before ?

Thanks that is what i needed to sort that issue, I upgraded to try and resolve the original issue about the heater recommended by @T3P3Tony ,

I will redo config.g now and see what happens with the heaters.. thanks for your support.

@droftarts Well after some head scratching and working through my wiring you were dead right i had a short between the two ground plane's on a custom pcb which i was using as breakout board, the issue was when i was metering the hotend i removed the screws to get to the back of the PCB when i done this there is no short, but because i inadvertently connected the two ground planes to via's where the screws went threw the PCB and those screw's went into to a metal plate it caused a short.

Picked up a tool board from ooznest to replace my PCB.

Thanks For you support on this.
