Today I
decided to change the way how the main controller board is mounted.
By
default is just hanging on the frame and waiting to be shorted by the aluminium
profile underneath. It is not mounted securely (only one edge of the board, 2
small screws in plastic mountings).
I have
used jodbe’s design on Thingiverse (http://www.thingiverse.com/thing:193965). It has really smart solution to hold
all the wires – it has built in canals so the wires are not sticking out
anymore and the unit becomes very flat.
I have
just modified it slightly by removing fan’s mounting points, cutting away side
of the board and adding 2 mounting points for my frame clips. Depends on the
location on the frame, FULL
or FLAT
clip may be used.
This is
my design:
And
this is the print out:
Then I have
labelled all the connectors (X-Y-Z axis, Extruder, X-Y-Z end stops, Fan, 2
heaters and 2 temperature sensors:
In the
next step I have removed the board completely and mounted it on the printed
base:
Then I
have added 2 of my previously designed clips and mounted the base on the printer’s
frame:
After routing all the wires and connecting all the connectors I have
ended up with this:

How do you cool your controller board?
ReplyDeleteI don't :)
DeleteThe hottest parts are the stepper motor controllers - and these reach temperatures of 80C max.
My ambient temperature is usually 20-22C - if yours is higher and/or your bed is not running smooth (more resistance on a motor = more work on the controller) and/or you are getting steps skipped because of built-in over temperature protection in the controllers (they will switch off to cool down) - then I would consider even a small fan blowing onto the board.

почему у меня не выходит ось Z,X? в чем дело может в контроллере???
ReplyDeleteHi,
DeleteI see 4 possible issues:
- mechanical: the rods are not parallel and the bed can't move to the home position but this does not apply to the Z axis of course,
- software: are you using Repetier or for example OctoPi sitting on RaspberryPi? What happens when you press Home?
After powering up the printer, the current position is treated as a 'home' so you can't lower the Z axis as the printer thinks this is the '0' position and you can move it only up (then down but only to the previous position). That's why homing is important so the printer learns its origins.
- slicer settings: one of the first commands in g-code should be to home the printer. This allows the printer start from the home position before every single print,
- printer settings: did you change printer's home location in the settings? The printer may now apply an offset to it's home position. You can define where the home location is.
Cheers,

Да нет в ручном режиме тоже оси не двигаются вот по Y все нормально и в перед и назад двигаются а по X только в одно положение двигается по Z вообще не двигается
ReplyDeleteНу спасибо хоть кто то отвечает
Hi, do you have an oscilloscope for example to see if the logic board tries to rotate the motor? It's weird that the stepper motors operate only in one direction.
DeleteWhat if you press 'home' button and then manually the axis stop buttons mounted on the frame and under the bed?
может что с контроллером????
