MGN12 Carriage does not lay flat on Tap_Center

Open joseph-greiner opened this issue 2 years ago • 4 comments

I was looking at the CAD for the Tap an noticed interference between the MGN12 carriage and the tap_center component. I printed the STL in the repo, mounted the carriage with the belts installed and noticed that the parts mount at a slight angle to each other.

tap_center_released

The issue is that the chamfer for the bottom of the carriage on the tap_center part is too big and will not let the carriage lay flat, even with belts installed.

compare

By cutting out the large chamfer and adding a 0.4mm chamfer to the area the carriage now lays flat.

it appears that some MGN12's have a different chamfor spec than others, I will update the STL.

please look at the updated tap_center_r2 file and let me know if you see need for more than that, I like to keep some chamfer there if possible

I am printing it now, I will update when it is finished, but the support was not exported with the part STL.

Printed the r2 STL, the carriage sits flat now.

I think this can be closed now, thank you for your feedback.
