Help Needed with Mark two and its Firmware

[bob-hepple 59]

I Posted this under the Mark two but no One replied so I thought I would try outside of that TAG,,,

1st I cannot get the Firmware to do a Pid tune on either of the heaters when I set it going it has a target temp of 150 which it soon passes and then says temp to high ?? what is the procedure to do a pid tune??? with this Firmware??

 

Next is a bit more tricky I set the bed levelling up, I got the 2nd head docking and un docking I did the Z offsets for both nozzles but when  ran the calibration code the head ploughed into the plate ?? this nocked the steppers off and after that nothing worked the head broke the docking bracket, which ill re print But when I bring the head to the front (Move) menu,,  the X cross slide hits the parked head two... any Ideas where I went wrong  ect ???

PID, try this:

Bed leveling:

Try to do the regular single head leveling first, then switch to head 2 and do the z offset calibration only for that.

For the crashing into dock change the wipe position Y offset to about 45.

thanks for the reply I will try the y offset when I get the bracket re printed as this got destroyed in the collision.

 

as for the levelling I did as you suggested, but will try again 

 

I have Pm'd Tinker Gnome as the printer in single head mode retracts the filament half the Bowden tube length of filament at the end of the print....

 

Thanks
