Disregarding maximum flow rate, cooling issues and keeping speeds the same, a 0. A good hardened steel nozzle costs just as much, and the volcano options aren't cheap either. Many in the industry have become solely fixated on cubic feet per minute (cfm) numbers, placing importance on a number that is easily manipulated and ignoring other data about a cylinder head’s performance. . I again calculated new flow values with which I ran a 3rd test interation after which the walls of each temperature were pretty close to 0. If we take this Benchy right here and compare glossy and matte surfaces to the flow visualization, so how much material is extruded per second, we can see that they perfectly correlate. It depends on the design requirements and needs. PLA. Next, the thermistor short check – to test this, locate the thermistor connector on your mainboard, then set a temperature and with for example some tweezers, short out the two pins of the thermistor connector. I just wanted to do t. Don’t remove that mesh. I just wanted to do the same. . 1 like September 8 at 3:48 PM. 9. RE: Automated method from CNC Kitchen to evalute the maximum volumetric speed. Unfortunalty as mentionned by @mahtDFR ( and also in the CNC Kitchen publication ) This solution seems to be not very efficient on a Bowden machines running under Marlin. Here we see the flow rate on the x-axis and the amount of expected under-extrusion on the y-axis. The final extrusion multipliers were 113% for 190°C where no foaming occurs, and 57% for 220°C, where we have the maximum expansion. The stringing test looked a bit hairy but the PC blend was able to reproduce the details very. Import the STL to slice, you may import multiple models. In terms of printing. This is precisely what happened to me a bunch of weeks ago while filming my filament recycling video. Do you want to become a reseller?

Make sure your Extruder acceleration is set high enough to take affect in the Klipper config. Seeing that, I instantly thought it would be cool to see how the ported Iron would fare. to individually adjust the Project for any printer. Fixing my flowrate through a slicer seems much more suboptimal than printer config/firmware so I'm wondering what my options are here as I've also already done pressure advance tuning. As the name RapidChange already suggests – one of the main advertised features of Revo is the ease and convenience of nozzle changes because no tools are needed, and it can and should be done, while the hotend is cold.
