Solved Z axis Short when using Simplify3d

So i have been using simplify 3d ever since i purchased this printer. I began having issues with z axis being short shortly after buying it in matter control and simplify3d. So i updated the firmware in matter control to V3, now matter control prints perfectly. But simplify3d still prints short and not smooth either. Does anyone have any clue as to how i should go about fixing this issue?

Below are a couple pics of 20mm cubes The one on the right was done in Simplify3d and is a bit short and and the other on the left was done in matter control. and is the correct height and has a smoother surface.

 

It could be because mattercontrol is storing the Z steps per mm in the EEProm so when you switch software it doesn't transfer.

Have you flashed your firmware?

It might also be the threaded rods are getting stiction and need lubrication. Or the stepper driver is over heating and needs sufficient cooling.

 

I did oil the threaded rods up with white lithium grease. I also flashed the firmware using the Arduino software using the steps described in the website firmware page. In matter control it says "Up to date" at the bottom when i connect to the printer and gives me the option to revert. As for the stepper drive i am not sure if it is overheating or not, but if it is, is there a reason why it would only have a problem when using simplify3d and not matter control? Im not realy sure what EEProm is so not sure how to go about that one.

 

I don't know why one slicer would change things that much, meaning it's probably mechanical or firmware.

Make sure the fan on the bottom of the printer is getting sufficient cooling just to be sure.

If that doesn't work contact simplify3d. They support their product well.

 

Ok well thats stuff seems to match, im talking to a guy from Simplify3d right now ill see what he is thinking as well

 

So just an update. Turns out that the z driver was overheating more with simplify 3d than with the stock software? not sure why but either way after 8 or 9 more test cubes it completely fried (with a working fan). Anyways replaced the driver and did all the stuff with the z screws using the 3mm bearings and coupler adjustments using the lock tight (removable). And its printing fantastically. Only thing I am trying to figure out now is adding another fan maybe larger to help with cooling the z stepper area as the stock fan is not directly over the z stepper diver. As of right now i have it overhanging a table with a big fan plugged into the wall under it.

Thanks for all your help guys

 

All the steppers currently have heat sinks, trying to wire another fan and mount it onto a block i made in the bottom of the robo now. =)

 

OHHH!!! you meant the motors, no those do not have heat sinks. i didnt even think the motors could be the issue! ill try that as well, cant hurt hah,

Thanks!

 

Did you try printing lifter feet to improve the airflow to the Ramps cooling fan?

 

Yup i sure did, that was one of the first things i tried to help with cooling after i realized it was still getting too hot in the z area
