Repetier CNC with TB6600

prakash11

Hello,

I am willing to run my cnc using tb6600 but motors dont move. i checked them with follwoing program-

**************

#define dirPin 40
#define stepPin 46
void setup() {
  // Declare pins as output:
  pinMode(stepPin, OUTPUT);
  pinMode(dirPin, OUTPUT);
  // Set the spinning direction CW/CCW:
  digitalWrite(dirPin, HIGH);
}
void loop() {
  // These four lines result in 1 step:
  digitalWrite(stepPin, HIGH);
  delayMicroseconds(70);
  digitalWrite(stepPin, LOW);
  delayMicroseconds(70);
}

**************

  Note for delay is 70. stepper running fine at this delay.

But on repetier STEPPER_HIGH_DELAY 70 resulting in no move.

Also applied -

#define X_ENABLE_ON 1
#define Y_ENABLE_ON 1
#define Z_ENABLE_ON 1

(Note- No of extruder and thermistor is zero for  CNC purspose)

But no luck.  Stepper not moving

What next to do?

RAyWB

change STEPPER_HIGH_DELAY 70  to 1 , that´s the setting i have on my cnc for TB6600.

prakash11

Already did that with configuration defaults. In that condition drv8825 running fine but when replaced with tb6600, it stopped.

RAyWB

what´s your board and how about wiring?

prakash11

It is arduino mega+ramps1.4 and from ramps step,dir and enable pins to their respective motors of x y and z axis as shown in here -

limit switch- x min, y min, z min+max

RAyWB

just following this thread should make it work.

step+ , dir+ and enable+ connected to +5vdc

step- to step pin

dir- to dir pin

enable- to enable pin

and

#define X_ENABLE_ON 1
#define Y_ENABLE_ON 1
#define Z_ENABLE_ON 1

that´s the settings i work with

prakash11

Actually i am trying to build one from last 5 months but no luck. tried grbl for uno and mega. no result. tried marlin. no move. now at repetier. no progress.

My stepper driver dont have step- dir- enable- they all are +

here is the image-

RAyWB

can you post a picture or drawing of your wiring?

prakash11

Here it is https://photos.app.goo.gl/QbwPYnsffciRtGn99

Nothing is different just taking inputs from ramps to drives. Only one endstop is plugged as of now to just check. only 2 stepper drivers are connected for testing.

5V from ramps to 5v input to tb6600

RAyWB

there is a purple cable connecting the +5V inputs of the stepper drivers.

I cannot see the connection from there to 5V of Ramps

prakash11

5v coming from 5V pin on ramps. Yellow cable (At bottom) is providing 5v from ramps to tb6600 drivers.

RAyWB

did you ever measure the servo 5v pin? not shure if the 5V are really there as far as i know ther is a jumper necessary

RAyWB

try to get 5V from Aux1 connector, then it should work ,

5V at servo Pin is not supplied from arduino.It has to be supplied from external as servos draw a lot of current.

prakash11

Connected from vcc pin from ramps as it is providing 5v output (tested using multimeter). when trying to home x or y axis board hangs as can be seen on display attached to ramps.

RAyWB

set STEPPER_HIGH_DELAY  to 1 or 2  before testing

prakash11

when i power them all using 24v supply it shows idle. In idle state en is at 5v dir at 5v and step at 0v. When homing command issued Dir is 0v Step at 5v and enable at 0v. These are readings on multimeter.

RAyWB

what are your settigs from this`?

#define X_ENABLE_ON 1
#define Y_ENABLE_ON 1
#define Z_ENABLE_ON 1

maybe you have to change these to 0  or if they are 0 change them to 1

guess after homing command enable has to be 5v

prakash11

Changed stepper high delay to 2 and aslo
x enable on 1
y enable on 1
But no progress. Pressing home for any axis hang ramps as no sound from rotatory encoder until pressed reset.

RAyWB

whats the endstops settings?

after starting homing firmware waits for endstop to be triggered/untriggered

so it does not really hang

What´s reported after sending M119 ?

prakash11

End stops working fine, normally off when pressed shoes on on riprap display.

RAyWB

what happens when you send gcode ?

f.e. G1 X50 Y50 F500

After commanding this gcode sound of fan from PSU24V goes down. Now i can not hear that sound but before command execution that was pretty much clear.

After disconnect and reconnect sound became as loud as earlier.

RAyWB

sorry, no more idea from my side .

but as you wrote :"After commanding this gcode sound of fan from PSU24V goes down"

I you should check 24V during operation.

not shure what happens

BTW:

15:47:15.793 : FIRMWARE_NAME:Repetier_0.92.9 FIRMWARE_URL:https://github.com/repetier/Repetier-Firmware/ PROTOCOL_VERSION:1.0 MACHINE_TYPE:Mendel EXTRUDER_COUNT:0 REPETIER_PROTOCOL:3

why are you using this old Firmware?

prakash11

OMG. Thanks a ton. Now repetier firmware latest version compiled and uploaded. It is moving. I was using that old version bcoz it was stable release.

Now let me check everything working fine of not from display.

Thanks for firmware version suggestion.

RAyWB

i remember, it´s a hard way to get the first machine runnig, so have fun now!

prakash11

Now it seems that stepper missing steps bcoz moving y axis moves stepper in one direction and sometimes opposite direction. Should i try delay? And what is that coming just below of printer name on smart display? how can i change that showing $&#... like characters?

RAyWB

changing direction is usually steppers current setting, refer drivers manual how to do.

also might be loose cable on dir input

regarding display no idea

prakash11

i mean to write that i am rotating the encoder in one direction but motor is misbehaving.

RAyWB

btw : hope you don´t supply ramps/arduino by 24V

this will kill arduino's voltage regulator soon.
