Front Idler height

[harry-boe]

Pleas reduce the height of the front idler by 0.2mm

Frame extrusion do not longer align when used with a Z front rail for the Try-Zero mod.
It might as well improve the threads on the m3x25 mounting screw.

Interesting - mine have clearance, but if the rails are slightly longer, I can see what you mean.

There's a comingled issue here, which is that the Y drives get in the way of the motion of the Z parts with Tri-Zero too.

A few soln's I can see to help with both:
(1) Ditch the second front idler part. It will be single-supported, but so what? The overhang is the minimum possible and we know this works just fine in other places. That will free up the maximum of extra space. <-- I'd strongly recommend testing this with a 20mm screw and some washers to give the end clearance.
(2) Counterbore the lower front idler part, to enable use of a 20mm screw, without the drama of washers. You'd have another unique part, but so what? It's tiny. And the shaft is double-supported, so nobody can complain about a within-reason single-supported shaft :-)
(3) Slightly shorten the lower printed idler part. But this wouldn't do anything to address some of the lost Z, hence why I'd want to try 1 and 2 first.

Thoughts? I'd suggest a bit of X-acto-ing or sanding as a quick workaround, or just shrinking the lower part in the slicer by the amount needed.

I changed the design an lowered them by 0.2 mm
with the new printed parts i get on side dead on the other still 0.1 mm off
