i believe i have the current adjusted properly now, and in the mid range of the signal it works fine, but the start and end it just buzzes, this is freely running the nema 17 with no load. I think based on my experience building a cnc, that the acceleration settings need to be adjusted.what do you think, below is current
//#define DEFAULT_AXIS_STEPS_PER_UNIT {36.36,36.36,640,640} // default settings for for mUVe 1-1.1
#define DEFAULT_AXIS_STEPS_PER_UNIT {36.36,36.36,400,400} // default settings for for mUVe 1.5 or if you have the leadscrew upgrade
#define DEFAULT_MAX_FEEDRATE {600, 600, 20, 20} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {4000,4000,4,4} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
#define DEFAULT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for retracts
how did you come up with the z axis height 320000 figure?
i am so close! everything seems to be responding much better, just that the motor shakes back and forth, so probably a board or wiring problem...
i have a acer 6510 run off pi3, so I dont need the pwm connection you mentioned right?
Can some uber successful user PLEASE post a youtube video how to connect
-nema 17 1.8 degree 200 steps per rotation, 16 rotations per inch
-ramps 1.4 with polulu step drive .8volts
-nanodlp step settings?
-ramps proper marlin code for z axis, limit switches, steps, etc. acceleration
my printer plate is run by a m8 screw. Thanks. ready to chuck it all and buy a form 2 but I have $600 invested already.
I get a little noise, a little movement, and my total z height around 125mm with limit switches on both ends.
good news bad news.
ok I got it working!!!! Thanks!!!
bad news
I have an Arduino mega with a ramps board on it and 5 polulu stepper drivers. my printer z axis is run on a stepper nema 17.
I may or may not have fried a lot of it on the last project, but before I started this one I tested and was able to get one of the stepper locations to run the motor.
I loaded the muve marlin software on the board and tested the usb connection to make sure I have it listed right in the nanodlp. but cant seem to get anything moving.
whats the easiest way to connect up a z drive stepper for this? direct to pi, or direct to Arduino or......
does it matter if I have steppers instead of servo?
any help appreciated. Thanks
thanks, based on that info i probably have installed it 5 times over. now to figure out the rest....
Can someone help me install nanodlp on a raspberry pi. Ive spent all day and cant seem to get it done.
I got rasbian jessie loaded and pixel and the pi works fine.
i loaded nanodlp.img on to a sandisk 16 and 32 using several different types of programs(unetbootin, win32) but no success. i close down the pi, take out the sd, put in the sd with nanodlp on it, and power on.
the program seems to be loaded tons of lines, then the screen goes black. if i hit enter after a few minutes it says something about deleting libraries files.
