Another revelation!
Part cooling fans. When you buy your part fan (5015 blower fan) make sure you get the ball bearing version! The other one make a serious racket when printing fast. I spent a solid year trying to figure out what was rattling on my V4. It was the fan…
Question for all of you that built the V5. Did you upgrade your V4 or build a new V5?
I am having a quandry about this. I have two Hypercube CoreXY machines, a modified Ender3, a FLSun-SR and my V4. Neither of the Hypercubes gets used these days and the Ender is relegated to the basement also.
The Ender has Dual Belt Drive (KevinAKASam) and new Manta control boards with CB1 and prints like a champ.
The original Hypercube is running Marlin with Octoprint and honeslty has not been turned on in years.
The Bigger Hypercube has a Manta M4p and CB1 in it with a H2 on it.
My Options:
Tear down the V4 and convert it to a V5 using the Manta M8P in it so I have the extra drivers to run my Trad Rack.
Tear down the Hypercubes and move the M4P to the Ender3. Use the Manta E3EZ with the 5 drivers to run a New V5 (Can bus on the tool head so that handles the 6th driver. I think I can use the SKR board on the original Hypercube to run the Tradrack Via USB… maybe. or just get the BTT board and move forward.
I seem to remember someone doing a partial upgrade but I can tseem to find it.
Maybe @orob ?
Yes, I did a v4 to v5 upgrade. I had to chop 25 mm off the x carriage linear rail and widen the frame for X about 3 mm and get longer pieces for the bed T-bar support, move some extrusion a bit, resquare it, and buy new belts and a couple more toothed idlers. It looks very similar. I used laser cut acrylic for the milled pieces because I don’t yet mill aluminum. I’m struggling with flooring pieces.
Aluminum might be easier 
That engineered wood flooring is notorious for dulling up sawblades
At this point is where I have now decided to build a new frame. I like my ACM panels on the V4 too much! Need to see just how much 2020 I have stashed away. Will probably reclaim a bunch as I tear down the Hypercubes also.
I agree with @Michael_Melancon . That stuff is horrible to cut with anything.
I built a new V5 and still have my V4. But I do plan to rebuild the V4 into a V5 one of these days. I have new extrusion here so I can add the 25mm extra to X and not have to cut the linear rail down. I added that extra on the V5 and have liked having the extra space. Also plan to do a new frame so I can add the top section that the V4 didn’t have. I have all the panels and such drawn up in CAD already just need to build it all.
I also have a pair of Honey Badger stepper motors here to try out on one of them. Those same motors came in the kits for my Ender 5 Pro and Plus Zero G upgrades. They run the same klipper configuration for the steppers as the MP3DPs do and they are practically silent where the MP3DP’s are LOUD! Cant really see where the motor would make a difference but worth a try at least lol.
I was surprised how little the frame change was and the fact that I had to cut the X rail to have the same amount of travel for X. it is still 300x300. Maybe I did it wrong… but it works well.
No the V5 does use less X rail than the V4 for the same travel. I don’t think you did anything wrong. And its good that you are seeing the benefits of the V5 over the V4!
Anything you’d like to change, or do differently for a future 5.x build?
Figure out how to make the motors quieter 
My V4 is super loud to and whenever I try to turn on Stealthchop it starts losing steps badly.
I think that is where I am too. I am trying to not spend a lot extra and use the stuff I already have around. The Hypercubes will net me 7 motors so I should be covered there…
I wasn’t loosing steps with stealthchop, and it was quieter sometimes, but when a travel move would hit, wow that was the worst noise ever. Way worse that with it off lol.
My V5 is a little louder than the V4, but mostly because its a different tone. That one has TMC5160 drivers and 48v going to the X and Y motors
You going for the sub 2 minute benchy?
No not even close. That orbiter is great but it cant melt enough plastic any where near fast enough for that.
Mostly it was me just wanting to learn and see if it was any better/different. I will say out of 4 printers that I have basically built from the ground up, that one has the best accelerations and all. The V4 and both ZeroG printers cant keep up with it in that aspect. But the hotend I have on both the ZeroG printers will walk circles around the Orbiter V3. That’s why I want to try to fit an orbiter v2 and Rapido on the V5, then see what it can really do.
That is where the Stealthburner comes in!
I know! That’s why I am watching this and hoping you get it all figured out so I don’t have to LOL
I got some nut inserts from a friend. But i dont have an extruder setup for a stealthburner mount. What were you planing to use?
I had planned on using a V6 that i had lying around but ran into some issues with the filmetrix cutter mod with it. I have a Voron Revo coming next Monday.
Lookimg at cost there are other cheaper options but as i am running a revobon the v4 it made sense to stay with it.
