That moment in your build

LowRider CNC Your Builds

Anyone else ever find themselves in the middle of a LR4 build, or any other significant project, and then realize…

“Oh. THAT is why the materials list and instructions were like that.”

For me, I sadly just came to the realization, that yes… there was a reason one side of the gantry had a single set of bearings, and the calculator didn’t double the length of Y rail you needed.

Turns out Ryan designed the LR4 with a single Y rail to avoid binding, and I just tried to magic one in on full autopilot.

Oh shoot. Luckily that is a simple fix.

Hahaha, yes. Of all the things that could have gone wrong, a pretty harmless mistake.

The only serious downside of cutting a second Y axis rail, is the temptation to build a second LR4.

What is this downside you speak of?

Congrats on getting your build assembled and running! Seriously sturdy framing you have there.

If it makes you/someone feel better, while assembling my LR3, auto pilot (not being present) resulted in me cutting a perfectly measured EMT section for the gantry that wasn’t needed (i.e. cut 3 instead of 2 :man_facepalming:). That mistake, and many others, is still sitting around somewhere… Reminding me to read and think more.
