Stabilizing X Axis on 0.4.7 and Earlier Designs I built my SmartRap using mostly a set of parts based on the 0.4.6 version. I may upgrade to newer parts over time. The main thing that bothered me was the amount of bending upward the X axis does during Z-homing, exacerbated by the fact that I'm using a servoless probe method. I figured out a quick 2-cent solution, literally, and figured I'd share. I haven't tested it much yet, but so far, I'm impressed with the improved rigidity. Hope this helps someone. :) [attachment 37492 2cent.jpg] https://reprap.org/forum/read.php?344,389057,389057#msg-389057 Fri, 10 Jul 2026 16:52:30 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?344,389057,389123#msg-389123 Re: Stabilizing X Axis on 0.4.7 and Earlier Designs https://reprap.org/forum/read.php?344,389057,389123#msg-389123

You can also put some paper, or soft plastic between the LM8UU and the top clamp.
the 0.47 has 3mm holes on the sides there so that you can clamp it down by screwing M3 's in.

LOL @ Reg, it's cheaper to drill a hole in a coin then actually go to the hardware store to buy a washer.

Not in my case. I have over 60,000 washers in stock already. The coins are not available here any more that will fit.
I biggest problem is to package the washers, nuts and bolts ha..ha..
I overcame the problem with the Z axis by designing a new one and turned the rods around 90 degrees.]]> regpye Smart_Rap Wed, 30 Jul 2014 05:18:04 -0400 https://reprap.org/forum/read.php?344,389057,389119#msg-389119 Re: Stabilizing X Axis on 0.4.7 and Earlier Designs https://reprap.org/forum/read.php?344,389057,389119#msg-389119 the 0.47 has 3mm holes on the sides there so that you can clamp it down by screwing M3 's in.

Can't use that idea in Australia any more. They took the 1 cent and 2 cents out of circulation and are now talking about removing 5 cents as well.
$1 dollar is double the size of our $2 (go figure)
I guess we would have to use a washer instead ha..ha..

Yes a good idea, I used a piece of scrap PLA to wedge in mine when I built the .46 model, it worked too.]]> regpye Smart_Rap Wed, 30 Jul 2014 00:39:27 -0400 https://reprap.org/forum/read.php?344,389057,389057#msg-389057 Stabilizing X Axis on 0.4.7 and Earlier Designs https://reprap.org/forum/read.php?344,389057,389057#msg-389057
