ABS printing with “slurry”
Please look at:

I checked this easy, low cost method for adhesion to a glass printer bed, gluing parts together and filling cracks.

Very good!

ABS Warp Reduction by added Pull-Down Clamps
There are already dozens of advices how to reduce ABS warps, here my contribution with experimental data!
Please look at the pdf attachment
Best regards

Dear Sam
The warping problem is solved now with pull-down clamps, glued to the bed with ABS Juice.
Now I construct a perfect “wind shield cover” over the JGaurora 5, tested carefully with an artificial near-by smoke generator.
You will not never believe how cold air enters by tiny slits through the protective cover to the bed with ABS-samples!

Kind regards

How is the slurry with the black diamond bed? I am a bit wary of applying acetone to it.

Dear Richy
With painter tape attached to the black diamond bet, lubrificated with a "ABS Juice" thin layer I got always good results. 
Perfect connection of the printed ABS object, easy to remove with later heating up to 80 Deg

Aceton is agressive, you should it not apply on other professional bed supports!

Not perfectly solved is the ABS warp problem. The best is a auxiliary ring around the objects, for controlled skrinking, see my next report about  x-axis clamps for x-offset prevention

Thanks for sharing your experience @Peter3 - and welcome

X-axis rods tuning by clamps preventing x-offset with less friction

Dear members

I observed many times an x-offset, with well cleaned and lubricated x-axis rods!

Finally my wife and I have observed that the x-rods are not parallel.

With two clamps, manufactured by ABS 3D-printing, this problem is solved now by tuning the x-rods parallel within 0.01 mm.

Please look at the attached report and the gcode-file

Kind regards

And here the STL-file for the clamps

Hi @Peter3 , I've just updated the forum software - please try uploading the file again. Thanks.

Dear Sam

Thank you for adding the GCode for the production of the x-axis clamps to my post!

Attached is now the STL file .

The original Fusion 360 document can be downloaded with the link: https://a360.co/2x29YYP

And here my more accurate results about the compression of rods at the left side:

1. Pressing the rods on the left side needs forces of about 25-30 N!

2. Experiment with the upper original JGaurora spare part axial ball bearing, loaded by (original 25 N vertical force, due to non-parallel x-axis) shows a horizontal axial friction of about 1.5 N with a lot of NOISE.

3. Without (or minor) vertical radial forces the horizontal axial friction is below 0.25N

I think that the original JGaurora axial bearing works fine if not overloaded (with its tiny balls) by excessive radial forces!

If the x-rods are well parallel adjusted to 35 +/-0.05 mm the x-axis works fine, no excessive lubrication required.

Best experimental greetings
