@deckingman Ian, your setup is very interesting, I have never seen counterweights used in this way,

I also have a melt efficiency concern as I will run 200mm/s, 0.4mm nozzle, 0.3mm layer height will a normal e3d hotend manage that throughput?

ps. I´m working on a welding robot that will weld printed pla components using a hotend and extruder. The problem is that I need to get into 90 degree corners with the nozzle and pump filament into them, it needs to be close enough to the material to bond to it before it cools. Most heating blocks and nozzles are not shaped for this and will not fit into corners, do you know if there are any more compact nozzles and hotends out there that might work for this job?

@wilriker Hi Manuel, Thank you for taking the time to help me with my project.

I see from your calculator that going beyond nema 17 is unnecessary.

What width of (GT2) belt would you use, the Y axis belt will be very long and 5mm seems narrow for a 3800mm long belt?

Hi

I´m planning a large Duet 2 xycore with a print volume of 550 x 1000 x 50mm (x,y,z) It is for a specific project an I will exclusively use PLA with print speed as main objective (200mm/s) at the expense of quality.

my concern is that even with bowden the moving mass will be between 700-900gr and that at these speeds a nema 23 will not be sufficient. If that turns out to be the case, would servos for the x/y axis be feasible?

ps, can you also tell me the most reliable method of calculating the torque requirements of this system?

best regards
Gísli
