MGN12H rails small tweaks to perfect…

Ok, the rails are on and working a treat, kind of…

The right angled fittings I purchased to secure the 20×20 extrusion to the 40×40 have some little tabs on them, I can’t find any readily available way of securely making this connection with off the shelf parts so i’ll have to grind down one side’s tabs…

The slight amount of pressure this tab is putting on the extruision is enough to twist it and stop the MGN rails from running smoothly!

View from below…if I add a little drop down to the right hand carriage, it’ll be easy to re-use the existing limit switch by mounting it on the side of the 2020

Close ups of the existing limit switch and the protrusions on the right angled mounting block.

Overall, minor things , but shows you should plan things a little in advance and test fit stuff before ‘going for it’

Fortunately this is nothing a quick angle grind and carriage print can’t fix….which means re-assembling the original printer to print a new bit, D’oh!
