A note to the followers of this thread, the OX plates have been revised to version 8.1 to resolve tightness of the Z plates on the X axis.
This issue was noted a few weeks ago in the OX thread. The problem is due to tolerances in the extrusion that have changed with the latest...
Yesterday I was doing a bit of testing regarding threaded holes for 5mm screws in Delrin (aka POM, acetal) and found that a 3/16" drill bit...
If the pre-made units are too big, make your own. It is really not that difficult. Ref:...
As the same machine can be built in either a 2x4 configuration or a 4x2 configuration merely by adjusting the length of the rails, it become...
I have a feeling she prefers Trish (rather than al). ;)
Considering a year ago most sizes of V-slot (as well as many other parts) would be out of stock for 2-3 months at a time and now lack of...
I can't help with the first part of your question but you can get more readable dimensions and a model from the Sketchup file posted here. Note...
@Dekes1, can you give us an approximate shipping date? (So others who purchased around the same time can take a closer look) Also, have they been...
You are confusing several concepts here. Your machine will have 3 axis, 4 motors, and 2.5D motion. The stated number of axis a board can...
That is already the subject of another thread. Let's please try and keep this one focused on the original subject.
The 20T pulley requires a 1.5mm.
What you are referring to in regards to breaking up large works into sections is called toolpath tiling. A brief discussion on the subject is...
@SatMike, where are you finding these prices? I can't seem to find anything close to that.
What you are considering has begun to stray too far from the above example. A 300x400 table is far too big to be stable on such a narrow based...
@sfbayman, based on measurements you should be able to fit up to 12.2 mm diameter down through the slot which would be pretty tight but doable....
Sorry, I was measuring the side plates. The X-axis carriage plates are even worse at 78.87 mm. These should be no less than 79.7 mm. The wheel...
The Rev. 80 file shows the vertical hole spacing at 99.3615 mm which is too tight. It should be 99.7 mm at an absolute minimum to work with the...
If you are looking at built-up sections to increase the gantry stiffness, consider aluminum tubing. As all the material is concentrated at the...
