I guess I learn something new every day. The motors I got from Ahren last June had 2 piece connectors on a short (12" ish) pigtail. I hadn't heard about the resistor at the motor being a problem,...

My motors have 2 part DB9 connectors with the resistor inside. Yours should be the same if I'm not mistaken. No need to cut anything.

Yeah, they were a little heavy. I cut off a 3' end to use for the short ribs and a 2' strip off the remaining 9' length for the long ribs. Pushing those pieces through the table saw was much easier...

Finally got around to picking up some 5' x 12' sheets of 3/4" MDF (they were out of 5' x 10'). Cut all of the internal and external strips for the torsion box and dry fit the internal framework. I...

I agree with Sean. Sure ballscrews are good, but that's not what I'm using. I said in my second post that I have my R&P parts. That part isn't up for discussion. I'm looking for help building the...

Not sure I follow. Are you suggesting I make the gantry support beam out of laminations of wood all going in the same direction as opposed to building it like a long, thin box?

This picture is a better shot of what I was planning for the gantry sides, although the gantry was just slapped together at this stage.

Notice how the sides have been thickened above the top...

Thanks for the feedback. Yeah, that's the part that I'm struggling with. The way the pinion has to line up with the rack means I have a particular thickness I can use to join the upper and lower...

I've already received a fairly complete package of parts from Ahren, including 5 extended carriages, 3 standard carriages, 3 NEMA 23 rack and pinion drives, a G540, parts for my Z-axis, etc, etc.

After a long time lurking, I've (like many others) finally taken the plunge and acquired most of the parts for my first router build. My plan is to be able to cut full sheets of MDF with a little...
