  Not sure what the problem is. Configuration looks ok if you connected thermistor to T0 and extruder heater to D10.

  
  

  Extruder motor will only turn if extruder is hot or if you had send M302 S1 to allow cold extrusion.

  
  

  What I don't see is FEATURE_FAN_CONTROL so I assume you have no filament cooling fan. Otherwise D9 would be used by that by default overwriting a heater that wants to use that output.

  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 mystery for the hotend heater issue. I will take a look on my wiring again.

  
  

  I was able to print again, but I have a problem on the first layer print. 

  Initially, the print started on 0.3 mm for the first layer of print.

  I did not see anything printed. the extruder head just go round and around.

  Then I changed the first print layer to 0.5 mm, and it started printing.

  However, I notice it lack of adhesion between layer on the x-axis of the brim.

  The brim crumble out like a layer of spaghetti put together.

  The part that I print has an issue on the surface, it has rough finishing.

  
  

  My hypothesis at the moment is the bed is not level.

  Do you think it is reasonable assumption?

  
  

  Funny you pointed out that FEATURE_FAN_CONTROL is not available on the code that posted above. I have cooling fan, and I noticed it did not turn on, even the display shows the fan is on.

  
  

  Do I make a mistake in wiring?

  or should I post the FEATURE_FAN_CONTROL line on my firmware?

  
  

  Thank you for the guidance.

  What display shows fan is on? On host or printer LCD? If it is printer lcd you have compiled it and D9 is the output normally. Host will not know if you have a fan and only looks if you have send the command, so that does not count.

  
  

  If extruder is too close to bed it will not extruder only try. If distance is too high it will not stick (also if bed condition is wrong it will not stick as well). At the beginning of skirt it will also not stick as it takes a bit of extrusion to get it going good.

  
  

  If parts stick and others don't it normally the bed that has different distances so rotation is bed. Hard to say remotely what problems match your case.

  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. 

  The fan is now working, as I wire it to extruder 0 port, recall the hotend does not heat up initially when it connected to extruder 0 port, but work when I connect to extruder 1 port.

  
  

  I was able to print a thin part, after I level the the printer bed. However, as I try to print a thicker part, i.e.: 10 mm part, it started okay, but as it goes to 2 to 3 mm higher, the printing result start to shift. 

  I tried to print at slower speed, through slowing down speed in slicing configuration. I use Repetier host and Cura Slicer. I reduce the speed to half and increase the infill configuration, but I still receive the same misalignment/ shifted layer as a result. 

  
  

  Now I suspect that either the extruder motor speed, either is too fast and/ or the z-axis movement is slower than the x-y movement. 

  
  

  Is there anyway that I can control the printing speed for z and. or extruder from the firmware?

  
  

  Thank you, and sorry for all these long winded questions.

  First you could set ALWAYS_CHECK_ENDSTOPS 0 which disables endstop testing. If endstops trigger from crosstalk to motors/heaters your print shifts away from endstop over height. That is a well known issue many have. If that is the case try twisting your endstop and motor cables (should be anyway) to reduce crosstalk.

  
  

  Other reasons might be jerk too high or acceleration too high. In these cases shifts are more random.

  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 the latest version, I think 1.6. I believe there is something in arduino compiler that did not translate correctly when it uploaded to the machine.
  2. I added more stabilizer on the base of the printing base, I.e. put some shim on the bottom of the table.
  3. I reduce the printing speed to 75% manually. This help with the quality of the printing.
  4. I made adjustment to the steps per mm for all the motor, based on some suggestion from YouTube channel. Very simple process, but it takes time to do so.
  
  If I would like to reduce the speed and acceleration of the motors in the firmware, which line of code should I adjust?
  
  Once again, I am grateful for the help.

  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.
• Repetier

  October 2016

  The only drawback is that without ALWAYS_CHECK_ENDSTOPS  you will not detect if you lost steps so head goes outside print area. But since that causes exactly this to happen I see no disadvantage. We test area in addition anyway (al least in dev).

  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 between layer.
  I believe this is still a crosstalk problem, is it true?
  
  Btw I try to understand the crosstalk.
  How do you fix it?
  Do I need to bundle a motor cable with the end stopper cable, I.e.: y motor with y end stop, etc.?
  I read from some other group, it mentioned about wrapping the cable with aluminium foil.
  Does it make any sense wrapping the cable with aluminium foil?
  
  Thank you.

  The default laser driver only supports laser on and off. Here you control the eíntensity with

  you can set the intensity in a range 0-255 with a custom extension to the driver. See driver.h

  and comments on how to extend the functions non invasive with our event system.

  
  

  If you have a laser - powder system you will like your E override. If moves contain a

  increasing extruder position it will laser that move. With this trick you can

  use existing fdm slicers to laser the output. Laser width is extrusion width.

  
  

  Other tools may use M3 and M5 to enable/disable laser. Here G1/G2/G3 moves have laser enabled

  and G0 moves have it disables.

  Crosstalk is caused by electromagnetic field from motor/heater cables. Simple solution is to twist these cables so fields change direction and effects even out. Foil around motor/heater cables shields better for the field.
• vsusanto

  October 2016

  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.
• Repetier

  Do you cool your stepper drivers? If the get too hot motors do strange things as well.
• vsusanto

  October 2016

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

  October 2016

  It depends on current set on drivers. If you go near limit a extra cooler is helpfull with decent currecnt passive cooling also works. Just test temperature of heat sinks.
• vsusanto

  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 top of it.

  
  

  Since to mention about the current set on drivers, I could not get the good reading on these driver. I meant the voltage reading on the these drivers does not match with the instruction that I found online.

  I used DRV8825, and what I can tell I am running about 2x voltage than my calculated voltage value. If I reduce it to 1.5x, the motor would not move. I purchase 2 sets of these drivers, and there are no difference in voltage reading.

  
  

  Did I do something wrong here? 

  
  

  Thank you for your help.

  I can't advice on hardware - not my field. But as it works first 5 minutes it might really be a temperature issue. So add a fan pointing on drivers - that cools much more then passive, so the state from first 5 minutes should hold the whole print.
• vsusanto

  October 2016

  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 rounds (I have built a square print object as a test). The shifts are not on the following layer, but on the x-axis.

  I will try to install a fan pointing on the top of these drivers.

  Also, I am going to try to increase the step size on the z-drivers to 1/16, as I think it does not need 1/32 stepper and I can lower the z-axis step per mm on the firmware.

  
  

  I understand that you mentioned about you can't give an advice on the hardware, but have you ever come across the problem with the board that cause the layer to shift?

  Is it possible that the current regulator on the board not functioning correctly?

  
  

  Thank you for your help.

  Only board I know that have/had problems was rumba board, where Y step line crossed other line on board too close, so it sometimes got a wrong step from interference. 

  
  

  Current on board is ok I think or you would get firmware crashes, connection problems ...

  Most professional printers cool the drivers for a good reason I guess.
• vsusanto

  October 2016

  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 z ports are sitting side by side.
  I am curious, How do other users getting over the problem on rumba?
  I thought about connecting the z axis motor in series to a stepper drive, but I against it due to potential overheating on the driver.
  I will e interesting to learn about the solution.
  Thank you.
• Repetier

  On rumba you simply connect y motor to E1 socket. You could use Y socket as E1 instead. For extruder the lost step is real issue.
• vsusanto

  December 2016

  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 the process of replacing the leadscrew. I have experienced lost e-step in certain print height.

  
  

  Thank you for your help and support.
