If fillament is 1.75, OD of PTFE tube is 4mm. solution is to tight fit little bearing with inner diameter 4 mm to extruder, and glue ptfe to inner of bearing...or slightly bigger bearing to fit one more printed part inside that will tight fit to tube and extruder..one of solutions i have ordered arduino+ramps, stepper motors, when components arrives then i play with it also have i think 12 pcby woo - Polar Machines, SCARA, Robot Arms
yes, for extruder...when hot end nozzle is centered in the middle of bearing, there is no problem, right? one dumb question...in wich file are kinematics config files? for example i open repetier firmware and in configuration.h are delta settings(arm lengths etc) but i missed subroutine wich calculate that parameters to linear motion-defines delta kinematics.. sorry for stupid question, like iby woo - Polar Machines, SCARA, Robot Arms
something new to this topic: my final configuration will be ramps+arduino, 4 pcs nema 17 2.5A, 4 pcs tb 6560...wish me a luckby woo - Controllers
well, first, i have diy cnc router for few years, so fabricating parts isnt problem. i look those anti cartesian machines for atleast 10 years Z axis, well rising table looks ok to me... in diy I always choose to fix 2 axis to frame, because if i have play in first axis, that play multiplies with play on second axis and so on... design goal is to make it ultra light and, actually this designby woo - Polar Machines, SCARA, Robot Arms
Hey, anyone use this drivers? any reviews? will they work plug n play with ramps?(b version)by woo - For Sale
hello,before many years i have spotted a interesting plotter design, i made simple sketch, but i dont know whats name of this design. it looks simple, and very light, what do you think for xy?by woo - Polar Machines, SCARA, Robot Arms
Hello, i have just one simple question i have cnc machine for 5-6 years emc driven (actually it was fun to make it, i dont mill anything at home because i have mills, laser cutters etc on job haha) now i have plan to make delta reprap, with standalone arduino, so...can i use steppers, drivers, powersupply with any arduino board? steppers are nema 23 i dont remember how strong, have 4 tb6560 coby woo - Controllers
