Rostock Mini G2 - Zeroing/leveling XYZ

[SteveShein]

I hope someone has a nice easy to follow method to zero and level off my XYZ. I am trying to follow this http://www.instructables.com/id/Using-R ... ng-G-code/ but if I send a GCODE command like "GO X0 Y50 Z2" the printer tries to punch the nozzle thru the bed. I can get it to stop in the center of the bed using Z10.

It also mentions this "If the 3 numbers differ too much, you can manually move down the print head until the nozzle just hit the print bed, and screw the endstop screw tightly, if the screw has no room to adjust, you need to change the following setting later, record it. E.g. Change 213.5 into 214 ". Can somebody please tell me where this "endstop" screw actually is?

Assuming that I can get it to use Z2, how are you supposed to measure the gap between the nozzle and the bed?

After that part I start to get a bit lost, and could sure use some kindly advice. There has to be an easier way. I'm on Day 3 of my build now.

Thanks!

hi,here is the latest upgraded firmware for rostock mini g2.it will help you zero/level xyz better.please reburn the firmware.
the endstop screw is shown in the picture.good luck.

Thank you very much, I will re-burn and let you know the results.

I continue to have difficulty. After burning the new firmware, I also did the recommended other firmware edits for this printer.

I now have a broken spider plate. What is there that should stop the machine from going to positions that are not valid and will break components?

It's hard to print parts when your printer is broken

if you could not print the broken on your own,maybe you need to buy a new one.if needed,please contact salesman.

I have the same problem. Following the instructions the only thing does is to make the extruder crash into the bed plate.

could you tell me what's your z axis height.in the firmware,it is set to 200.but you need to modified it according to your printer actual height.normally,the value should be more than 200.
#define MANUAL_X_HOME_POS 0
#define MANUAL_Y_HOME_POS 0
#define MANUAL_Z_HOME_POS 200// For delta: Distance between nozzle and print surface after homing.
