One person reported that a computer simulation indicated that Z belt stretch was a possible problem as the center of mass of the XY gantry was constantly changing.

compare that to beds that are only suspended at one side like in the ultimaker, which can cause wobble. i think this is more of a theoretical problem than a practical one.

I'm not a fan of cantilever bed designs but they are not an inherent feature of Ultimaker XY kinematics.

I've seen cantilever bed designs on CoreXY printers and I would not be surprised if there are other kinematics where folks have tried cantilever beds.

But that still leaves the question what is the upside to a voron design?

its a iterative design for printing high temperature filaments well.

@Veti Yes I would go for the Voron also but it isn't ready to print. I will look at your link, thank you.

I personally would not use a voron design.

The additional issues associated with moving the XY gantry on the Z axis would be my concern.

One person reported that a computer simulation indicated that Z belt stretch was a possible problem as the center of mass of the XY gantry was constantly changing.

I see no upside to the design and a possible downside.

CoreXY designs are currently quite popular but there are also Ultimaker designs and MarkForged designs to consider.

Just my two cents.

Thank you for your contribution. Actually the Voron is out because it isn't assembled. I will consider other option.

I'll build you a voron for $10k

The smaller Tractus printers may fit your budget and size requirements, https://tractus3d.com/.

That doesn't really tell us why the XY gantry should be moved as opposed to the bed.

@fcwilt

because its lighter than the bed?

Thank you, I will have a look at it.

I have no idea. Steppers are not exactly lightweight devices.

And it's not like the bed needs to move up/down quickly in the way the XY axes need to move so does the weight even matter?

While there is some wiring to the bed it is less than the wiring to the XY gantry.

It's just a gut feeling but moving the bed seems the better approach.

I will be launching 2 printer series "soon" that will be enclosable as well as using Duet3D hardware (with the option of either RRF or klipper).
You can see the first unit of my slinger series I shipped to an early beta customer in action at 7k Acceleration here. That's a 400x400 bed moving that fast! Results - The top print was from that video!

The keys to my printer design are as follows:

Any hotend/extruder combo - it adds some bulk, but the gantry plates are sturdy aluminum and have a variety of holes for mounting whichever hotend you'd like. The unit shipped was a e3d Volcano, but on my personal unit I run a slice magnum with an orbiter extruder. I have a Lily pellet extruder on-order and will also be making adapters.
Scalable volume - Both printer series are any-sizable, they rely on common joints that just have scaled extrusion/linear rail.
High temp capable - The slinger specifically was designed for bolt-on panels that will enclose the volume quickly and cheaply without complex machining. Bed is capable of 140C, after that alternative options will be needed for magnets on the removable sheets
Nothing is proprietary about it - this will be released open-source just like my Stablebot Core design currently is. Run any slicer, firmware, filament you want.

The other printer is my stablebot Core, with the repo here: https://github.com/lukeslaboratory/Stablebot-Core
I have the parts on-hand for a single-extruder build which I will be using a slice magnum, but the same principles apply. This machine currently runs a D3 6HC with A 3HC extender, but with a single-extruder option, could run on a D3 Mini 5+ with stepper expansions.

Great work, your table moves a lot !

I need a ready to print printer, not a kit, for my company.

@bricoletout I will happily ship a completed Core or Slinger in whatever configuration you'd like for a fair price. I've sent you a DM, otherwise my email is Luke@Lukeslab.online

That picture does not exactly fill me with a feeling of confidence.

@fcwilt Yeah - wiring is my biggest struggle, its why the toolchanger will be another couple months as i figure out how to keep them all arranged.

I wasn't talking about the printer at all - rather the very happy bearded dude crouching inside the printer - an odd place to find a very happy bearded dude don't you think?

What if the customer doesn't want to purchase a printer complete with a very happy bearded dude?

@fcwilt and barefoot at that!

The hobbit pictured is very happy to live inside the printer where he was made!

The XY (for the gantry itself) should be solved with Seperate-but-connected cable chains along the X and Y axis, but every solution I've tried with a "supported loop" similar to the E3d/Jubilee cable chain has been as kudgy as shown, particularily for the 1meter+ cables I currently use. for anything over 500+mm in a single direction, I'll probably have to make it so that only CAN devices can be used to reduce wire mass and complexity, so i can still use a zip tie or ruler. I have the 1LC's ready on Hemeras, and am excited to give them a shot as time allows

@Luke-sLaboratory

To be honest I never looked at the printer - I was taken aback by the very happy bearded dude - who, as mentioned, is barefoot.

Perhaps you would engender greater confidence in your company with a more "serious" presentation.

I will now look at the printer.
