First test of this custom build for a client. Still have some wiring cleanup to do and a minimum of 100 hours of reliability testing. Really happy with how this one came out. 3DXTECH Carbon fiber PETG used for all printed parts, this filament is awesome! All CNC machined in house, 350 x 350 x 270z. No Chinese junk used, NSK, Hiwin, Misumi, Vexta motors, BBMAN pulleys, and Gates belts. Shielded cables for motors and critical sensor wiring. I think the client will be very happy.
Thats a beast.
Well done !
Wow ,can you share a pic of the finished benchy shown in 1st pic, wanna see the print quality
The task of taking into account shielded wiring goes to show the quality in this build. Awesome build.
That thing is amazing! It’s gotta be heavy as all hell though. Lol. How much is this guy paying you for it? It’s gotta be a couple grand, right?
That is a massive bed. How much does the entire machine weigh?
@Kevin_Danger_Powers as someone building a printer, this mustve cost more than just a couple grand. You’ve got linear guides for the X and Y axis, bondtech extruder, LCD touchscreen, and custom machined parts. I’d say a couple thousand for the materials plus another couple thousand for design and testing.
Put this in a environment controlled cabinet with wheels, a dehumidifier cabinet lower and you have a rig anyone would be envious of. Outstanding Build!! Do you have any videos out there?
@Buhda_Pete_Punk Been working on that. I’m planning on doing a few videos of some previous builds plus some 3d printer related tech/ how to’s from my own perspective as a machine builder. I’m going to have to completely redo my office and I have a custom work bench being built right now that will work as a video presentation platform.
@Adam_Steinmark SolidWorks estimated around 65lbs with defined material properties for all the parts in the assembly. I can say with confidence that is a very close estimate having to move the printer around a few times during the build process. I went a little overkill on the structure because I plan to use this platform as a universal small desktop machine platform for mills and pcb mills in future builds.
The client already had the bulk of the electronics: Duet/LCD, Bondtech, and some other various components from a printer that this one will be replacing.

@Devadath_P.R Benchy was the very first test print. I’m surprised it came out as good as it did considering there was no PTFE tubing in the heat break causing retraction issues. The extruder jammed right after the Benchy test print and that’s when I found out about the missing PTFE tubing.

@Kyle1 Is the bed AC heated by any chance?
@Adam_Steinmark Yes, 750watt Keenovo 120VAC
@Kyle1 if you don’t mind me asking, what parts of the frame did you ground? Just the buildplate or all the frame parts as well? I’m trying to figure out how much I need to ground in my machine. I’m using an 800W Keenovo 120V AC heater.
Machine is grounded to earth ground from ac line. All shield ground wires ground at single point. The bed should also ground to this single point as well. Do not mix Earth grounds with isolated power supply DC grounds. I suggest googling proper system grounding and difference between Earth ground and isolated DC supply grounds.
Absolutely beautiful. Please share prints!
@Kyle1 Yeah I’m using a switch for power which runs to my DC supply and an SSR for the bed. I’m just trying to figure out of I need to run a wire to AC ground directly from anything besides the bed.
It’s a good idea to ground the frame since it can act as an emi antenna.
@Kyle1 Did you just ground a single component of the frame? I’m trying to figure out what’s reasonable.
The whole frame is grounded. I grounded to a single point in the frame. The frame peices being aluminum are conductive (I machined through the anodizing where the bolts are at all joints) thus grounding to a single point anywhere on the frame will ground the frame. However you have to make sure there is continuity throughout the frame using a multi meter and checking for continuity from your single ground point to all frame peices.
