Newbie question - how easy/hard should it be to turn the 8mm Acme screw? I couldn't find anything in the discussion or on YouTube that covered...
Barry - where do you get the flat cable & what's the vendor name & part number? Four of my steppers are fixed so I can use stiffer cable on them....
I had a very pleasant surprise today. I decided to cut off the unused portion of a C-beam actuator. When I went to tap the holes I decided to...
I hadn't heard of a forming tap before. Sounds like the pros like them in aluminum. There were several mentions that hand threading using a...
I just did 8 more M5 holes in a piece of V-slot using the drill then tap method. I screwed up the first two holes! Guess I got lazy over the...
Amen to the combo drill/tap in long holes. Just too many problems.
RATSS!!!! - the M5 drill/tap reamed out several of the holes enough that an M5 bolt just slides in & out. I can drill & tap them to M6x1.0. The...
Justin - thanks for the feedback. I'll use my over sized (18 awg) wires on the Nema23 steppers and the E3D heater and then probably get 20 awg...

The wiring comment brought up an item I've been wondering about. I was REALLY surprised when I saw the wire sizes on the stepper motors and on...
Rick - I bought the motors 6 weeks ago when I thought I'd be doing the big fixed bed 1.5M x 1M x 1M. I knew this was bigger than most of the CNC...
On the moving bed design, if I rotate the Z actuators by 90 degrees I'll end up with an x/y movement of about 16" x 16". That's plenty for me....
I have no way to calculate/simulate how the system will perform so I'm hoping for feedback from people with experience. If I wanted a 12" Z...
Bob K published a new build: This is my journey from a dream machine to a practical (for me) machine. This is a Cartesian style frame that can...
Yes, a 3 mil spacer makes it much better. A 4 mil spacer is definitely too much. thanks Bob
This is my first build so I expect that, once again, I've selected the wrong parts or are assembling them wrong. Your help would be much...
Maybe it's too late at night ... and I'm surprised to not see any mention of this ... What are the (top level) steps to switch between milling...
