Unanswered I think I am losing steps on Z axis.

I love mattercontrol and my Robo3. It has been 1 year of non stop printing. Recently I have been having issues with the prints. It seem the problem is in Z axis. Print starts good and somewhere after 20 min into the print I start to lose steps. Basically the print comes out shorter in size and clearly missing some parts of the print. I have cleaned and lubricated the shafts, changed the print speeds, changed .stl file, and still got the same problem, did a full un-install software and re-install and the problem persisted. As a last resort I decided to change the software to CURA... and the problem went away... I prefer mattercontrol ability to preheat the machine.... Is there a way to do this in CURA? What could be wrong with mattercontrol? Is this a common issue?

 

Update on the issue. Currently I am having the same trouble with CURA. I think the problem may be hardware related.

Yes it does it both on Cura and Matter Control. Actually now it starting to make a clunky sound coming from the stepper motor.

When you refer to the stepper driver are you talking about the motor or something else?

 

Ok I was not able to communicate with the Arduino Mega 2560this to see the current settings. So opted to upload a new firmware to the arduino with these values {80,80,2560,723.38} for DEFAULT_AXIS_STEPS_PER_UNIT I ran a print and I am still having issues.

 

Yes they have the aluminum couplers.

So you think it has to do with the ARDUINO + RAMPS SHEILD 1.4 FULL ELECTRONICS CONTROL BOARD?

 

Ok I am guessing that they can be replaced. Where could I get such a replacement?

 

Cool thanks a lot I have some homework to do! I will let you know what happens!

 

I think this is the same problem I am having the same issue but I also get it in cura
