Thank you Repetier.

Repetier,Since the last discussion, I decided to change the board back to Melzi at the moment. I still have the RAMPS board for a future upgrade. In regard to lost e step, I noticed that one of my leadscrew is bowing or no longer straight. I am in t…

That's it. I looked at rumba board, and my board has similar layout, where the other z axis stepper board is on the other way of the board.my printer is using 2 z motors. It has to cross y axis port. Originally, the printer is using Melzi, where the…

Repetier,I convinced now that the problem is in current that regulated to these drivers. I have some A4988 drivers lying around with heat sink installed on the top of the chip. I installed it on the x-axis, and I saw the print shifted after every 2 …

Repetier, I noticed that the first 5-minute of printing is fine, no shifting. As the printing time progress, I start noticing more layer printing shift. I have five drivers on all the board, and all of them have a passive heat sink mounted on the to…

I put a heat sinks on the top of the chip. Should I put a cooling fan too?

Repetier, I am running out of idea. I have tied all the end stopand motor cables, shieled it with aluminum foil and cover it with electrical tape. The problem is still persist. Is there anything that I can do at this point? Thank you.

here is the configuration.h #ifndef CONFIGURATION_H#define CONFIGURATION_H /**************** READ FIRST ************************ This configuration file was created with the configuration tool. For that reason, it does not contain the same inf…

Repetier, I thought I fix the issue, but it still persist. Now it is in printing small object. I noticed that the movement snag in some occasion while printing. Is this mean the machine jerking? Afterward, I noticed the printing start to shift bet…

I disable ALWAYS_CHECK_ENDSTOPS and it seems the printing is better now.Is there any problem in the future, when this function disable?Thank you for the guidance.

Departure, thank you for the walk through for all the issues. At this point all of the issues have been resolved. Here are the steps that I did to resolve the problem: 1. For the shifted layer, I was able to fix it by updating the arduino program to…

Repetier,After several hours trial and error, I figure out the problem with the cooling fan. The Feature_Fan_control is on the firmware, already.I notice, 2-in-1 Sainsmart board has the pin arrangement slightly different than typical ramps board. Th…

Repetier,sorry for delay response. Since then, I have fixed the extruder motor issues. I made adjustment on the stepper drive by replacing the jumper pin. I also made couple adjustment to Z-drive movement on the firmware. I still trying to solve the…
