Yes David. Home all and bed problems have been solved. Thank you very much. But the engines connected to e1 and e2 drivers do not work. I checked the engines and the cables but there were no problems. Is there something wrong with the config file?

My best guess is that the E steps per mm @ 92.6462 are for 16x micro stepping but you've set the micro stepping to 256X. If that's the case, divide the steps per mm by 16 and multiply by 256 which will give you 1482.3392.
Edit. Or use 16x micro stepping for the extruders.
-
Check for error messages on the GCode Console page of DWC. To operate the extruder motors, two conditions must be satisfied:
1. You must have selected a tool (T command) that uses that extruder motor;
2 Either the nozzle for that tool is hot, or you have enabled cold extrusion using M302.

Hello. I choose the microstep 16 and I use 16x200=3600 formula and thread diameter is 11 mm. 11x3,14159=34,55749. I multiply this result by 3600 and write the result (110,534)to config file but although the flament needs to be 5 mm, it is 5.5mm.
-
Which thread diameter is 11mm, and where did you write 110534 to config.g? If you mean extruder steps/mm then that is much too high for an extruder. Typical values are 100 for ungeared extruders and 420 for 3:1 geared extruders, using x16 microstepping and 1.8deg motors.

Yes but he's using 256x times micro stepping. He had it set to around 92 but he'd set the micro stepping (to 256x) prior to setting the steps per mm. That's what I pointed out earlier and I guess that's what he was responding to.
Edit. It kind of leapt out at me when I saw steps per mm for X and Y at 2560, Z at 3200 but E at 92(ish).
2nd Edit. Don't understand the comment "I choose the microstep 16" when the M350 in config.g is set to 256.

extruder thread diameter is 11mm and it is running stepper motor directly. There is no gear box in between and I found the "set steps per mm" value using the formula below and wrote it in the config file. How did you calculate the value you wrote? Also my driver type is bowden. Can you briefly write me the logic of calculation?
e_steps_per_mm = (motor_steps_per_rev * driver_microstep) * (hob_effective_diameter * pi)
(200 * 16)=3200
3200* (11 * 3.14159) = 110.584 -
Those steps per mm are OK as a starting point for 16X micro stepping. My point is that in your config.g file you have M350 X256 Y256 Z256 E256:256 I0 which sets the micro stepping to 256X - not 16X. Then after that you have M92 X2560 Y2560 Z3200 E92.6462:92.6462 to set the step[s per mm at whatever value mcro stepping you used in the M350 command (in this case 256).
In your formula above, the "driver_microstep" value is 256 (because that is what you have set it to in M350) and not 16.
You either need to set micro-stepping to 16X then set the steps per mm, or set the steps per mm for 16X then change the micro stepping after and allow the firmware to do the calculation, or leave it as it is and set the micro-stepping first to 256X but then you must calculate the steps per mm using 256X.
It's explained in the wiki here https://duet3d.com/wiki/G-code#M350:_Set_microstepping_mode
-
e_steps_per_mm = (motor_steps_per_rev * driver_microstep) * (hob_effective_diameter * pi)
It should be:
e_steps_per_mm = (motor_steps_per_rev * driver_microstep) / (hob_effective_diameter * pi)
That gives 200 * 16 / (11 * pi) = 92.6 steps/mm at x16 microstepping.

I got perfect results by using 110.584 on smooth surfaces. But i will try your values too. By the way step engines overheat although max current is 2 ampers and although i run them 1,5 ampers. What causes this overheat. The brand of the Engines are moons.

[22:33, 15.1.2018] Yasin Kizilay: Hello there. In the RepRapFirmware Configuration Tool, in the Microstepping Values section, which step I choose in the Values section, the Steps per mm value always remains at 420, the old machine has the marlin software. I was writing the result into the related section according to the formula I gave above, I choose 16x on microstepping values section and engine angle is 1.8 degrees and the engine is directly connected without a gearbox. The extruder gear is mk8 and the diameter is 11 mm. Which values do I need to enter on the RepRapFirmware Configuration Tool page. Please help me. I am about to go mad.
-
I'm sorry, I don't understand the problem. I typed 100 into the extruder steps/mm box that originally said 420; then when I generate the files, I get E100 in the M92 command, which is correct.
