Bit of an odd one I will admit.I and using Repetier Host as a controller for my Anet A8. Repetier seems to think that the max height (z axis) of the printer is approx 36.8. I found this out when i was printing my first tallish print and the z axis stopped going any higher half way through, but the print continued to try and print, but obviously was just spilling over that layer over and over again.Slightly weird point is that repetier will let me go higher than 36.8 in controls, and this is reflected on the screen of my printer, but the actual z axis will move no more when setting the axis above 36.8.I thought this might be a hardware issue, so brought the printer up to 36, turned the printer off and on, and then moved the z axis higher - this worked fine. I then homed the z anbd tried to bring to 37 and it again got stuck a 36 - for me this narrows that its an issue with repetier.I have done all the usual things of checking the max z height is set correctly, tried changing this just in case, tried deleting and re adding the printer - nothing seems to change this magical number of 36.8.Any help would be greatly appreciated :) I can share photos if it helps, and happy to answer any questions the best i can!
