What is the max temp setup for in your firmware? If its close to what your heating too it will trip it everytime. If you heating to 215c and the limit is 220c then you will fail everytime. I have my...

My max temp is: #define HEATER_0_MAXTEMP 275. So I don t think this is the problem. What is weird is that this problem occur only when I want to print from SD or I order(from LCD) to the printer to...

Are your Z axis rods M8 threaded rod or M8 4 start leadscrews ? M8 threaded rod at 1.25 pitch should be 2560 steps/mm at 1/16 microstepping. 4 start leadscrews would be 400 steps

For what it's worth: Or you could just calibrate the Z direction. [reprap.org] As far as I know on the RAMPS boards micro steps 1/32 or 1/16 depends on which stepper driver you are using. If using the...

Your new leadscrews are most likely M8 4 start leadscrews (same as mine) so your steps will be 1600/4 = 400

That's why you go thru the calibration process. The calculations that you are doing are just a starting point. There are several things that can make the calculated value be incorrect. One of them is...
