Looking for a new 3d printer

[AutoWiz]

From all that I have read it sounds to me like you need a custom built 3d printer. Something hand made by someone of high skills to perform a specific task for you. The things that make a printer run fast do not come on store bought rigs. Marlin, Rep Rap Firmware(RRF), and all the custom firmwares out there are all second best to Klipper in the name of fast printing which requires a raspberry pi to run. The only way you will end up with that on your own is to buy a printer and start modding it. But also print speed at the end of the day is ultimately determined by how fast we can extrude and lay down that filament. So as we chase the high speed printing we need specialized extruders that won't skip on the filament or deform it before it feeds it into the hotend. And the hotend itself needs to have a larger melt zone in it to allow for the faster moving filament to have a chance to melt on its way to the nozzle. And then the controller. Can you believe a lot of the printers sold today are still running 8 bit control boards?! You will never print at a good speed with a machine that has an 8 bit brain that can think as fast and as much as 16mhz. That's like trying to get a brain damaged retard to stop drooling on himself and do your math test for you. Ya know? And 32 bit mainboards are all so very different from one another in terms of processing power. And that really matters as we chase actual print speed because the faster we hope to print directly translates into the faster the brain has to make more decisions. And then there is inertia. All of these printers are weak sauce and their frames so much less rigid that you would believe. And you will learn that as you try to ramp up speed on ANY printer. Because it is hard to stop a train and once we sling a carriage one direction at a certain speed inertia keeps that carriage moving a touch past the point where the stepper motor stops or goes the other direction. This inertia caused distortion in our print quality that is also identified as 'ringing' can be mitigated by correctly and thoughtfully bracing the frame and it's axes. By someone who actually knows how to do this I mean. It is for all these reasons that anybody in this hobby could only agree with that I suggest and extend my offer to you to build you a 3d printer custom tailored to your needs. I just need you to send me a whole lot of money and tell me more about what you would require out of your ideal 3d printer and we can get started ordering some parts and designing others.
