Re: Need a good table top scrolling CNC!

Re: Need a good table top scrolling CNC!
I really don't like how the ball screw is being retained on one side by just the flex coupler on the end of a stepper motor. It could be fully supported on the other end but it really should have a...

Re: Best CAM software
HSMexpress/HSMworks FTW. It's free, it's easy, It works with solidworks and it doesn't suck.
If your fabrication team knows a bit of solidworks then I'd have them do the CAM. If your CAD team knows...

I definitely agree with this, after looking at how few dual wheel shooters were competitive in 2012 and 254 in 2014 we thought hooded shooters were surely the way to go. Due to the low mass of the...

Re: Cheapish CNC machine
