Interesting. Why are you doing that?
-
Doing mesh probing to make sure first layer is accurate.
-
Doing just the print area to speed up the probing.
Thanks.
Do you have a problem with your bed warping/flexing/changing that requires re-creating the heightmap?
I've found that barring something unusual I can create the heightmap once and it works fine.

I am getting better results this way and it doesn't add much to the print starting time since it probes just the print area.
I added recently dual Z true leveling so maybe it's less needed now but doesn't hurt. BTW, it's not just the sagging X rods (2 x 8mm, not that stiff) may also contribute to leveling error. I think that's the weakest point in my HEVO printer, X movement is not that stiff The reset is very good.

Thanks for the info.
I had to look up what a HEVO printer was. I haven't seen a design that uses rods for X and Y like that.
Do they really sag enough to cause problems?

I can't tell for sure. They do hold but definitely not stiffed as say aluminum extrusion.
The rods based design came from Tech2C, the designer of the original Hypercube, which also tried a few different materials

My printer works well and I am happy with it but sometimes I toy with the idea of building a 'better' one and a stiffness is one of the key goals. Designed that I liked so far are the BLV mgn and the Voron Zero. Could also scrap money for a Tool Changer but this is cheating.

Have you checked out the E3D Motion System?
Looks the right printer for me. I don't need, nor want' the tool changing functionality. The design looks clean, motors and belts are within the frame as I like and I presume stiff and fast. Down side is that assembling it has less the 'home-brew' feel. I will add to my short list and look if the are available in my country. There are several resellers here , and I just looked at a few (Filastruder, Matter Hacker, Printed Solid) but failed to find it.

My finances took a big hit from the pandemic.
If things ever return to something approaching pre-pandemic conditions I plan to get one despite the price.

@zapta maybe the Jubilee printer is more up your alley.

Jubilee printer
Just took a look. Thanks. It looks as a decent design but aesthetically I prefer corexy with belts and x/y motor within the frame boundary. A less industrial look if you will.

I find it difficult to find reviews of the motion system or having it offered for sale in the US. Just the tool changer everywhere. I need only one fixed head. I have even trouble finding information and dimensions of the X/Y carriage that comes with the motion system to understand how to attach to it a direct extruder.
Anybody has good pointers with information and available in the US of the motion system alone?
