With the new thermistor installed and the nozzle at (pretty nearly) the right height, the final set of bar clamp mounts came out perfectly:
MPCNC – reprinted bar clamp mounts
They’re supporting the snippets produced by trimming the clamp extrusions to fit across the bench under the MPCNC; I figure they ought to come in handy for something.
Both extrusions carry a warning sticker giving the bar’s serial number:
Harbor Freight Bar Clamp Labels
Huh.
I could be persuaded the number applies to a given production batch, although I’d be unsurprised to learn it’s a batch of labels, not clamps.
They don’t look much different than the previous versions:
MPCNC – bar clamp mount
The main change was to raise the bars by another 2 mm to give one of the clamp shoes more clearance. As you might expect, the top and bottom halves of the clamp castings aren’t quite symmetric.
The plastic mounts come in mirror-image sets due to that off-center bolt hole.
Yes, the threaded casting is slightly angled from the screw clamping force.
All in all, the mounts look pretty good, in a bright-orange sort of way.
