Hi, everyone. I am trying to get my Bukito DIY knock-off 3D printer (X-Y-Z Cartesian co-ord) up and running but I am having problems getting my head around
the relation between various configuration items in the Config file. I have had a hard time getting as far as I have (couldn’t even communicate with the X5
mini board at first, Windows driver problems, etc.). It is somewhat my fault that I have had problems - I have told people I am trying a combination I
haven’t seen : sort of like trying match a Toyota Corolla car body, with a Ford Focus motor and a Mazda transmission.
What I have so far : (I will try to post a photo)(OK I tried but I guess I have low Karma! “Guests and low-karma users are not allowed to publish links on this site.”, even though I’m logged in)
Hardware : homemade, DIY copy of a Bukito (modified & slightly enlarged). The hardware part is pretty well finished.
Note : the Z axis is a 3/8-16 threaded rod in a Delrin nut to eliminate play
I have limit switches placed at X (min) (table all the way to the right), Y (max) (extruder all the the way to the back) and Z (min) (extruder all the
the way to the bottom)
Controller : Azteeg X5 Mini Smoothie Board
Extruder : E3D V-6 hot-end in a Bowden configuration (I have not assembled, installed or tried this yet)
Software : Repetier Host
What I have accomplished so far (I can communicate with my X5 Mini using Repetier Host (via USB).)
- I can now manually move the 4 stepper motors (X, Y, Z and the extruder motor)(using the Manual Control tab)
- I have been trying to get each axis to move smoothly and accurately.
- I played with the following parameter to get the motors to sound reasonably good :
alpha_steps_per_mm = 300 (I understand that this is the parameter to get the axis to move a real, correct distance) - I used the Belt Calculator (to calculate “alpha_steps_per_mm”); I input the following values for my machine : Motor step angle = 1.8, Driver Microstepping
1/32 (as per the documentation, I put a jumper over the M0 and M2 to get the 1/32 step size), Belt pitch = 2 mm (GT2 belt), Tooth Count = 30. The
calculated result was 106.6667, however, when I used that value, the motors sounded very rough. When I raised it to 300, the motors sound much better,
however, now the axis moves much further
- In regards to this - when I ask (i.e. the X axis) to move 1 unit, what actual distance is Repetier Host asking the axis to move ? (it seems to move about
1 inch - though I thought all movements were in mm?)
- I measured the movements with a ruler while moving in Manual Control :
Axis Value Commanded Actual measured movement G-Code Command
==== =============== ======================== ==============
X,Y 0.1 units ~ 9 mm G1 X0.1 F100
Z 1.0 units ~ 3 mm G1 Z1 F1000
- I can also HOME the X, Y and Z axes.
- The items I played with were the following items : (they work pretty well, though there is NO WAY that the X & Y axes are retracting 1 mm (more like 1
inch !) - the units seen very weird)
alpha_fast_homing_rate_mm_s = 2.5 # feedrates in mm/second (however, the X axis moves very quickly)
beta_fast_homing_rate_mm_s = 2 # same for the Y axis
gamma_fast_homing_rate_mm_s = 4 # the Z axis works perfectly, though the distance seems not correct because of the 3/8-16 threaded rod
alpha_slow_homing_rate_mm_s = 1 # the axis moves much faster than 1 mm/sec
beta_slow_homing_rate_mm_s = 1 # the axis moves much faster than 1 mm/sec
gamma_slow_homing_rate_mm_s = 2 # the axis moves much faster than 2 mm/sec
alpha_homing_retract_mm = 1 # distance in mm (retracts something like 2 or 3 inches)
beta_homing_retract_mm = 1 # distance in mm (retracts something like 2 or 3 inches)
gamma_homing_retract_mm = 5 # distance in mm (retracts something like 1/2 inch or so)
Note : while homing,
- the X & Y seem very rough and move about 3 inches while retracting
- the Z axis movement is very smooth and retracts about 1/2 inch
My Questions :
-
what actual distance is Repetier Host asking the axis to move when I ask it to move 1 unit? (it seems to move about 1 inch - though I thought all
movements were in mm?) -
I have a sneaking suspicion that the following paramters are somehow inter-related (though I don’t completely understand the relationships) :
default_feed_rate 100 # Default rate ( mm/minute ) for G1/G2/G3 moves
default_seek_rate 1000 # Default rate ( mm/minute ) for G0 moves

beta_steps_per_mm 300 # Steps per mm for beta stepper
gamma_steps_per_mm 300.00 # Steps per mm for gamma stepper

acceleration_ticks_per_second 500 # Number of times per second the speed is updated
microseconds_per_step_pulse 1 # Duration of step pulses to stepper drivers, in microseconds

gamma_max_rate 200.0 # mm/min actuator max speed
alpha_fast_homing_rate_mm_s 2.5 # feedrates in mm/second
