The led of the switch is a big help.
Honestly I can't be happier that I made my gantry to square via Mach3. When I moved it by hand I was doubtful that is needed. But once it moved 100m then the Hiwin loosened a bit and I see the benefit of squaring with a push of a button.

Yes and if using slaved motors it's also having the piece of mind that things are correct and dropped or missed steps are not building up.
Like I said before even thou gantrys are built and look strong and they will drive just from one side when pushed etc you will always get some racking to some degree or another. When one motor stops while other keeps moving then the mechanical advantage of the ballscrew even with relatively small steppers attached will twist even very strong gantry's like Boyan's(Silyavski) if this happens you have no way to know unless referenced with marks or switches.!

Hey Eddy,

Been away from the forum for a while and just reread your build. Really good stuff!

Just got myself a small workshop together (mill - lathe on the way) and starting to learn the ropes and having a blast!

Thanks!

Jim

Still not got a dust shoe sorted due to not having found the ideal design, maybe this is it ?
I'm going to make it out of wood first to see how it performs, then use perspex.
I wanted it to be adjustable so the bottom of the skirt was flush with the bottom of the cutter, or thereabouts. It's not so handy that my spindle does not have a rounded body and has air exit holes at the bottom for the top mounted fan exhaust. Skirt held on with 3 pairs of magnets, allows easy access and different length skirts to be used, mini, knee length, evening gown.

Any thoughts ?

I've always prefered "Around ankles". .

Sorry can't help much here but mate of mine made something similiar but it didn't work so well if I remember but not sure why.? Will give him a ring ask and report back.

Eddy, if you make it spring/pneumatic loaded, the skirt can be arranged to be always in contact with the media top face. The main disadvantage with dust shoes etc is that you loose sight of the actual machining. G.

Thanks, that confirms my thinking.

You'd be hard pressed to beat Bessey clamps. I've got got some K Body clamps and there's nothing else even close in terms of quality but the price makes your eyes water (although I notice they are doing a sale at the moment). I hope you are going to post a wide selection of pictures of the finished clamping jig. I must admit it crossed my mind to make a similar addition.
