I've got a Sainsmart Genmitsu that I extended the Y rails on using Openbuilds parts. 1m C-beams and 8mm leadscrews to go with them, including...
I've got an upgraded Sainsmart 4030 which is now probably a 4080. I've got 1m long Y C-beams. The unmodified version of my machine uses 15120...
Well, I'm annoyed and grateful. Spurred on by your suggestion, I got a metric tape measure. Well, I found out that my working area is only about...
The bolt pattern for the gantry is off, and there isn't enough play in the holes to make anywhere near close enough of a change. I may eventually...
I'd be happy to, but I'd need to buy another scale/ruler, since the one I have only goes up to 450mm.
I've upgraded my Sainsmart 4030 to roughly a 4090 (400mm x by 900mm y working area). I'm trying to tram it. I've got a Dewalt 611 as the spindle...
Got the leadscrews calibrated in GRBL. 197 steps per mm gives it dead on accurate movement over 400mm. I'm having a tramming issue, but I'll...

[ATTACH] Getting ready to tram the spindle.
I may or may not post the videos I took, I'm not sure they really provide a benefit. Upshot: 1. The leadscrews are straight, no bends. Removed...
Got it. I suspect the bend I'm seeing is flexing from my screw-up, not an actual set in the screw bend, because I didn't notice it before...
[ATTACH] [ATTACH] [ATTACH] This is what I have currently. So I'll move the one on the end away from the stepper motor so I can slide out just...
Thank you! I think either the guide I was going from lead me astray, or I misunderstood what they were saying. I have thrust bearings and lock...
I went ahead and ordered another set of leadscrews and had them sent Fed-Ex. They arrived right away. I've got them installed now. I need to...
Oh joy, the leadscrews are in USPS limbo. Been "In Transit, Arriving Late" since the 22nd. Last time this happened to me, it took 6 weeks to...
Thinking a little more about the parts sizes, I'm using 12150 extrusion for my table. If I use the 1000mm C-beams for my Y-axis, I'm going to...
[ATTACH] Well, that is what I get for ordering parts in the middle of the night and not heading out to take actual measurements. And I did...
That was quick! About 30 hours from order to door, though to be fair, it was only about 50 miles. [ATTACH]
If they come back in stock soon enough, I'll go with the OB ones. Edit: Looking in the store, the ones linked to that were out of stock are the...
I've never actually replaced a leadscrew, so I'm going off the video guide posted above. If I only need 3, I'll be happy with that. If/when I...
