New member. Looking to eventually acquire a lathe and/or milling machine, when I accumulate the budget, that is.

Welcome to the forum Thomas,

What sort of projects do you have in mind?

Hi Neil,

My current projects are: a reflow soldering oven; a CNC router controller; and a SCARA based pick and place robot for electronic components.

If I had metalwork tools I would use them to make more tools!

This is the start of my 3D printed SCARA. For a sense of scale the dark bit is a NEMA17 stepper motor.

Looks interesting Tom, what printer are you using?

We have a 3D printer topic (we aren't as old fashioned as you might thinkl!)

Hi Neil,

I will be using my anet a8, it's a prusa i3 clone with an aluminium backed heated bed and z leadscrews.

In my SCARA each arm is over 200mm long so, to get better positional resolution I decided to use an 18:1 worm drive to reduce the whole step angular resolution to 0.1?. Obviously I have no idea whether the design will actually work, nor whether backlash will overwhelm the designed angular resolution. But, I wanted to check if anyone thought that the speed of the arm would be sufficient even with the 18x reduction.

I've no experience of implementing SCARA, but Joseph Noci is building a morgan style 3D printer and documenting it in another thread here which may have some issues in common?
