Re: [MakerBot] 2x belt tension

[Joseph Chiu]

If it's like the Replicator or the R2, it would be done by adjusting the X stepper mounting.    While holding the stepper, loosen the 4 bolts holding the stepper and then retighten after adjusting the belt tension.

Other than the oval issue, the printer is working great.  I am loving how easy it is to unload the filament!

See if you have this problem with your X belt to X carriage connection.  Mine had almost 1mm of backlash.  placed a business card thick shim between flat side of belt and flimsy plastic "clamp".

Also turned into MB and they sent a new slide which I have yet to install.

Good one Jetguy!
The only good thing is that I never had to pay for the printer, but I have to deal with the issues.
It would have been a nightmare had I not built 2 printers on my own and did some homework on the forums after receiving the 2x.

[nickythegreek]

Would I need to remove the extruders for that?

[Spk64]

Nope.
With the power off. Just grab the belt and see if the x carriage will move back and forth without the belt moving. Mine had about 1mm of movement.

[nickythegreek]

Spk64,

Yep, I have way to much play there.  I am experiencing the same issue as you.

[Spk64]

Ok, Here is what I did to fix. Remove extruders and nozzle bar.
Place one shim business card thickness between flat side of belt and the plastic tab.
See attached.
