Well… **DISCLAIMER** I'm not a fan boy of any one particular company. I'm buying everything with my own money so I have a certain amount of expectations as a customer. Like stuff working without having to tinker. This is my honest assessment of the printer from a relatively new to the hobby experience. This is not inteted to piss anyone off so no stone throwing.
It was horrible at first, but I think it was more about my less than a year experience with 3D printing. Up to now it's been the E3v2 and that thing has been modded to superiority. Waiting for a smart dude or dudette to do a good Marlin firmware build for the Vyper. Stock firmware does the most basic of jobs, but nothing special. I have read about some issues with the pressure sensor or something with the ABL on it. Mine seems to be fine. I had a hard time getting anything in Cura to print right. The extruder makes some noise during retractions, like a Creality style bowden setup. It does have a nice thumbscrew for adjusting though. Works fine with Octoprint and after fooling around with S3D for about a day (versus weeks on Cura) I got it pretty well dialed in. I will be throwing my profile up on this platform. I should have waited for the inevitable v2, but I'm happy with it now. Oh yeah, what the Vyper did prove to me is the tolerance of cheap filament. I had some garbage filament that was just horrible. I also print SLOW, like really slow. I think I'm ready to increase the speed after layer 3 since I got the bed adhesion pretty solid. Basically it's not a out of the box slice and print product, I don't think anything on the market is that yet, but, this is kind of close to that. Not having to manually level is nice. I recently put TH3D solid bed kit on my Ender with EZABL. I'm not a huge fan of the filament holder. It works, but just. It's not strong enough to really hold a full spool, recommend downloading and printing one of the many spool mods for this printer. even with that, it tends to lean under the load of a full spool. Not having to buy dual z axis kit's aftermarket is cool. This is longer than I anticipated so I'll wrap it up.
Would I buy another one? Yes, on sale. especially knowing it can produce really high quality prints with minimal tinkering.
Recommendations/what I would like to see improved? Use quality filament (of course), I would like to see the Firmware get a good Marlin facelift so M600 filament changes will work properly. I understand this is as much about the LCD as it is the firmware. So hopefully the screen will work with that. As with any 3D product out of the CCP, documentation that is more clearly written and not just a copy/paste of some other companies documentation. The screen shots should also match what's actually on the printer and not for the customer to fumble through.
Anyway, that's my two cents. I'm happy with the printer. It's got some warts but nothing thats a real show stopper. What it ultimately boils down to is that it's just another CCP clone of a clone of a clone. I think it would be funny to see a family tree of 3D printers.
