Cross Brace Up-Grade...

A good video on levelling the X axis (Gantry) on a dual Z axis machine by adjusting the steppers if they are out of step....

I have been doing a lot of printing of late, and noticed that the flutter and vibration coming from the whole printer frame is very noticeable especially when doing the taller prints.

I decided to use a temporary bar attached to one side of the upright and over to the back wall behind the printer, and it seems to have made a huge difference.

I’ve got some Aluminium Linear Rails on order to do a better job visually, and plan on fitting it when it arrives, I might fit one to the other side too, and I reckon this type of fitting is less intrusive than the front fitting type..

This type of fitting wasn’t great..

You remind me of a guy I met today at a garage sale. He was looking for tools, primarily for woodworking, especial old tools and machines. So far he's bought a couple items but has not made any finished product yet. Instead, he's been refurbishing the old equipment and making it more functional. One day he'll make some, by golly!

Anyways, great guy. Probably your cousin.

They broke the mould when they make me…so he must be from another batch..

You could always build one of these - completely rigid frame and very accurate

OK, but how will that stop the printer from vibrating due to very small head movement..
I'm all ears...

Should not be anywhere near the same vibration from a machine that does not run on wheels and has a rigid frame. An example of a CoreXy machine (belts and no wheels)

I would have thought that most of the vibration is a result of large movements and fast acceleration/jerk. Its the changes in direction I think that sets up most of the movement in the frame, but I'm no expert

I reckon your right about the change of direction, but I’ve set mine to print slowly, but that still doesn’t stop it vibration when filling in, maybe I should set it print solid..
The temporary fix works Feckin great..

Some infill patterns make more vibration than others, for instance the new Gyroid infill in Cura will shake the hell out of the printer. Linear fill is probably the least vibration but I have not compared them all. Slowing the infill down also helps but then the time to print increases dramatically.

Now my only problem installing the new part is… The Feckin dog hates power drills..
